Full textAbstract:
Demand for potatoes has grown rapidly in eastern Africa due to rapid population growth, urbanisation and life style changes. This has made potato an important commodity crop in the region contributing to food security and enhanced livelihoods. However, potato productivity in the region is low; ranging from 6 to10 t/ha against potential yields of over 30 t/ha. One of the major causes of low yields is the chronic shortage of good quality seed potatoes for planting, which also limits adoption of new and improved varieties. Therefore, the objective of this paper is to highlight the opportunities and progresses in the production and availability of good quality seed potatoes in the East African region to bolster the productivity and commercial value of the crop. The first section of the paper discusses the status of good quality seed potatoes production and availability in the East African region. The second section looks at the farmer-based seed potato production technologies while the third section focuses on the efforts of both the private and public sector in production of good quality seed potatoes. Availability of good quality seed potatoes constitutes < 1% of the requirement in eastern Africa. These seeds are mainly produced by public research institutions as well as some private players. Consequently, most farmers opt to plant seed potatoes from informal sources. However, seeds from informal sources are mostly of poor quality and often accelerate the spread of tuber-borne diseases, especially viruses and bacterial wilt. To improve seeds from informal system, some technologies have been identified and promoted to enhance farmer-based seed production and distribution. These include seed plot technology (SPT), positive selection techniques (PST) and Quality Declared Seed (QDS) systems. In addition, there has been adoption and promotion of rapid multiplication techniques (RMT) such as stem/shoot cuttings, aeroponics, sandponics, and hydroponics among others. Other measures that have been taken include importing seeds of new potato varieties. The imports increase the quantity of seeds and the number of potato varieties available to farmers. Despite these efforts, the quantity of good quality seeds available is still far below the requirements. There is need for the governments, private sector players as well as farmers to enhance their efforts and save the situation. Governments need to invest seriously in local breeding activities and multiplication of early generation seeds. These and other measures may increase availability of good quality and affordable seed potatoes in East African region.

The experiment was conducted at the research field and post graduate laboratory of Plant Pathology Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during 2015 - 2016 to find out the performance of different source’s seed potatoes and select suitable methods for improvement of farm saved seed potatoes. In the experiment, farm saved seed was compared with the certified seed, positive selection’s seed, seed plot technique’s (STP) seed Potato and Truthfully level seed potato as of BARI Alu-8(Cardinal). The maximum yield (27.72 t ha-1) was recorded from positive selection’s seed, which was similar to Certified and SPT seeds. The maximum plants of farmer’s seed potatoes (≥ 8 %, 7.33 % and 4.17 %) were infected by PVY, PLRV and PMV, respectively. The seed potatoes of positive selection and seed plot technique were the best alternatives to supplement the certified seed.

Full textAbstract:
The potato seed production system in Kazakhstan needs to be modernized to meet modern conditions and market requirements. There are cases when seed material of poor quality, both domestically produced and smuggled from abroad, is detected, which ultimately leads to low yields and the spread of diseases. In this regard, an objective and reliable assessment of the conformity of seed potatoes for the purposes of certification will act as a driver in increasing competitiveness and ensuring high quality, and taking into account the appointment of potatoes as an industrial crop and food crop, it will contribute to the issue of increasing the food security of the country as a whole. When developing a certification system, it is important to conduct a conformity assessment procedure by an arbiter independent of the producer and consumer of seed potatoes, that is, a third party. The introduction of a certification and inspection system will ensure transparency and objectivity in the cultivation of potato seeds, which will create prerequisites for a significant increase in investment in seed production and the development of seed exports. Work on the development of a certification and inspection system for seed potatoes meets the needs of the seed potato market, is in demand, timely and relevant. As a result of research on the development and implementation of the seed potato inspection service, an algorithm was developed for the work of the inspection service of the designated authority for the inspection and certification of seed potatoes and the interaction of the designated authority with other organizations on the issue of inspection and certification of seed potatoes.

Full textAbstract:
Empirical evidence suggests that certified seed potatoes (CSPs) are critical in boosting potato yield, increasing income, and improving nutrition and food security at the household level. Availability and access to certified seed multipliers increase the chances of smallholder potato farmers’ (SHF) uptake and use of certified seed technologies and practices. Most farmers cannot access certified seeds from these multipliers, forcing them to use and reuse the seeds saved from their local storage facilities. The paper sought to determine whether access to certified seed multipliers influenced potato smallholder farmers’ use of CSPs in Kipipiri Sub-County, Kenya. A closed-ended, researcher-administered survey was used in collecting data from 106 SHFs selected from the area. Descriptives and binary logistic statistics were used to answer the study objectives. The findings indicated a significant relationship between access to certified seed multipliers and the use of CSPs. From the study, only 40 % of smallholder farmers had access to certified seed multipliers, while the majority (60%) did not. This trend would be why the respondents opted to use other sources of seeds from farmer stores. Additionally, the high cost of certified seeds and lack of awareness of existing certified seed sources/multipliers were recorded as the significant barriers hindering farmers from accessing certified seed potatoes in the study area.

Full textAbstract:
The potato has been a widely used vegetable crop in temperate countries for a long time. Its consumption and the area of its cultivation has increased significantly over the past decades in the tropics and subtropics as well. The main problems of potato producers in the tropics and subtropics are the unsatisfactory quality of seed potatoes, mainly derived from the informal seed supply system, and the insufficient availability and high cost of certified seed potatoes. The hope for improving this situation can be the application of soil-less technologies for minituber production under controlled conditions. This publication focuses on important advantages of the aeroponic system in the production of pre-basic seed potatoes in the tropics and subtropics. It also highlights some deficiencies that can be overcome with the involvement of several actors in the potato industry, including local universities and the private sector. It emphasizes that innovative aeroponic installations are an opportunity to increase the production of high-quality seed potatoes in the countries of the tropics and subtropics, which, in many cases, will result in less dependence on expensive imported seed potatoes, often from a different climate zone. The introduction of aeroponic installations conserves the shrinking natural soil and water resources and contributes to their protection.

Full textAbstract:
The aim of the research was to determine the crop productivity, yield of tubers of seed fraction and infection of basic potato seeds with viral infection depending on the period of potato desiccation, application of mineral oil Sunspray, the number and species of winged aphids in the Polissia region of Ukraine. The study was conducted in the prebasic seed production nursery garden of the Institute for Potato Research, NAAS under the conditions of spatial isolation from the main sources and vectors of viral infections of potatoes, located in Nemishaieve, Borodiаnka distr., Kyiv region in the southern part of the Polissia region of Ukraine. The subject of the research is pre-basic and basic seed material of potatoes of mid ripening varieties Myroslava, Predslava, Alians.
On average for 2018-2020 years of studies, the highest seed yield was obtained by potato desiccation 10 days after flowering of potatoes - 82.4-85.3 %.
However, the level of total and seed yields was low. The efficiency of seed potato production increased with the haulm removal after 20 days - with the total yield depending on the variety 20.6-30.0 t/ha, the yield of seed tubers was in the range of 20.6-22.9 t/ha with the seed content in the crop structure - 71.0-76.3 %. Late haulm removal – on 30th and 40th days after potatoes flowering caused an increase in the yield of tubers of non-standard fraction, with desiccation on 30th day, the seed content in the crop decreased by 61.1-66.0 %, and with desiccation on 40th – by 54-59.8 %. Thus, during the early haulm removal, part of the crop was lost, which during haulm removal in the late stages consisted of large tubers.
It has been found out, that potato plants, where the haulm removal during 2018, 2019 was carried out within 10 days after flowering, which was 4.0 % (9.0 % for the check) for the Myroslav potato variety, 3.0 % (10.0 % for the check) for the Predslava potato variety and 4.0 % (9.0 % for the check) for the Alians potato variety were the least infected with PVM. The level of PVM infection when removing the haulm on the 10th day after flowering with the application of Sunspray mineral oil at a rate of 6.0 l/ha decreased on average for the three varieties by 1.5–2.5 %. The best option to preserve the quality characteristics of seed potatoes was to desiccate the potato haulm on 20th day after flowering of potato varieties Myroslava, Predslava and Alians and the application of mineral oil Sunspray - 6.0 l / ha. The yield was 28.8-30.0 t/ha, seed fraction 20.6-22.9, seed yield - 71.0-76.3 %, viral PVM infection was 2.0 3.0 %

Full textAbstract:
The importance of sowing vigorous seed is particularly well recognized by commercial growers of small-seeded sexually propagated crops. The possibility of producing clean potato seed tubers with true potato seed (TPS) has existed in many developing countries since the seventies. In China, about 15,000 ha of potatoes are grown with seed tubers originally derived from TPS. The possibility to establish a fast field-stand and to produce a commercial crop of potatoes within 90 days after transplanting TPS seedlings has only been recently realized. This paper outlines the methodology used and the results obtained during 10 years of study focusing on the most critical factors involved in the production and preservation of high-quality TPS. Seed dormancy accounts for the most important difference between the undomesticated TPS and other related crops such as the tomato.

Full textAbstract:
In the supposed or proven incidence of bacterial ring rot caused by <i>Clavibacter michiganensis</i> subsp. <i>sepedonicus</i> (<i>Cms</i>) in certified seed and commercial potatoes, five periods can be identified in the Czech Lands from 1910 to 2006: (<i>i</i>) high incidence of <i>Cms</i> in potato crops is claimed (about 1910–1929); (<i>ii</i>) very low incidence in certified potatoes and sporadic occurrence in commercial potatoes (about 1930–1985); (<i>iii</i>) increasing incidence of <i>Cms</i> in certified seed potatoes and its sporadic occurrence in commercial potatoes is assumed (about 1986–1997); (<i>iv</i>) a relatively high percentage of potato tuber samples proved to be infected by <i>Cms</i>, namely 1.14% in seed potatoes in 1998 and 4.13% in commercial potatoes in 1999 (1998–2004 period); (<i>v</i>) progressive decrease of <i>Cms</i> incidence to zero in seed potato samples and 0.19% in commercial samples in 2005, followed by a slight increase to 0.15% in seed potatoes and 0.23% in commercial potatoes in 2006 (2005–2006 period). Thus, up to 2006, <i>Cms</i> was and is not widely distributed in the CR and is actively and effectively controlled, mainly through the zero tolerance for ring rot bacterium in the seed potato certification program. In the CR, <i>Cms</i> has a relatively low capacity for damage and can hardly be considered as a pest of national economic importance. Strictly speaking, <i>Cms</i> does not fulfill the criteria for a quarantine organism. If, however, the quarantine status of <i>Cms</i> will be maintained, the severe post-entry measures against it should be relaxed.

Full textAbstract:
The potato became an important crop in the Faroe Islands early in the 19th century and subsequently vital in the 1820s and 1830s, when crofters started to enclose and cultivate small plots of land. These plots of land were crucial in ensuring population growth and in extending cultivated land. Local officials followed these events closely. During the 1830s problems emerged concerning the quality of seed potatoes and the limited supply, problems which only intensified as time passed. Concern was raised by one sheriff that difficulties in finding new seeds would prevent the expanding cultivation, whilst others worried that the deterioration in seed quality would result in a decline in growth, thus jeopardizing the livelihood of crofters. In this article the story of seed potatoes purchased by governor Pløyen in Orkney in 1839 is followed. The point being made is that by acquiring these seed potatoes the authorities ensured that the progress of the previous 20 years continued. Furthermore, the purchasing of a shipment of seed potatoes is linked to other modernization plans for Faroese society, which governor Pløyen and others worked on at the time. For these plans to succeed, it was vital to ensure the living conditions of the crofter families as change would not emerge from the old peasant society.

Being one of the basic food products in the Russian Federation, potatoe requires special attention to themselves as a crop from the certification bodies of seed material. Currently, in the Russian Federation, 83.5% of the used seed material of potatoes meets the requirements of the standard. However, this situation cannot be considered satisfactory, since the mass producers of potatoes continue to use non-certified seed. The article proposes measures to remedy this situation.

Full textAbstract:
The most important problem of the introduction of advanced potatoes seed system is to protect against repeated infection the healthy potatoes by viruses in the open field. In our republic the greatest risk to re-infection the healthy potatoes seed is Y - potato virus. The principal vectors of Y – potato virus, developing the largest number, are three types of aphids - buckthorn (Aphis nasturtii), alder (Aphis frangulae) and bean (Aphis fabae). The bean aphid is dominant, in some years its size rises up to 2406 copies. Relatively low coefficient of harmfulness (0.1 equivalent unit), provided the mass settlement on the plants can significantly increase the contamination of potatoes seed. The climatic conditions of the growing season, precipitation, relative humidity, which significantly affect the development and dispersal of aphids on host plants are of great importance.

Full textAbstract:
Virus-free seed potatoes are generally divided into pre-elite seeds and certified seeds. To study the differences in dry matter accumulation and distribution between pre-elite seeds and certified seeds through a field randomized block two-factor experiment, pre-elite seeds and certified seeds of four varieties were selected to explore the differences in growth characteristics between the two levels of virus-free potatoes and to find a way to improve potato seed expansion efficiency. The results showed that the growth process of pre-elite seeds was slower and the growth period was longer than certified seeds. The dry matter accumulation of pre-elite seeds in various organs was lower than in certified seeds, and the distribution ratio in the roots and stems of each variety was also lower than the certified seed, while there was no significant difference in the leaf and tuber distribution ratio. The average dry matter accumulation rate in both pre-elite and certified seeds was sorted by size of tubers > leaves > stems > roots; however, it was significantly lower in pre-elite seeds than in certified seeds. Tuber fresh weight, tuber volume, tuber number, and the theoretical yield of certified seeds were higher than those of pre-elite seeds. Experiments have shown that appropriately prolonging the harvest time of virus-free potatoes, especially pre-elite seeds, and increasing the proportion of dry matter allocated to roots and stems by pre-elite seeds in the early growth stages can effectively increase yield.

Full textAbstract:
To improve the efficient and precise seeding of potatoes, a novel combination vacuum and spoon belt metering device was designed. The overall structure and working principle of vacuum and spoon belt metering devices were illustrated and analyzed. The stress of the potato seed situated on the vacuum and spoon belt metering device was analyzed theoretically. The structure and parameters of the key parts of the seed metering device were studied and calculated. Three-factor and three-level response surface experiments were designed based on the Box–Behnken central composite experimental design principle. After selecting seeding speed, spoon aperture, and cleaning-seed air amount as the experimental factors and selecting missing seed index, multiple seed index, and qualified seed index as the experimental indexes, the performance of the seed metering device with high efficiency and precision was verified by the experiments. The mathematical model of the response surface was established, and the influence of each factor on the performance of the seed metering device was analyzed using Design-Expert 10.0.4 software. To improve the efficient and precise seeding of potatoes, the three experimental factors were optimized. Experimental results show that the order of the factors affecting the missing seed index was seeding belt speed > cleaning air pressure > spoon aperture; the order of the factors affecting the multiple seed index was spoon aperture > cleaning air pressure > seeding belt speed; the order of the factors affecting the qualified seed index was seeding belt speed > cleaning air pressure > spoon aperture; when the seeding belt speed was 0.43 m·s−1, the spoon aperture was 15.72 mm, and the cleaning air pressure was 2.94 kPa, the experiment had realized potato’s highly efficient and precise seeding and the missing seed index was 3.97%, the multiple seed index was 4.65%, and the qualified seed index was 91.38%. This paper can provide a theoretical and technical reference for improving the efficient and precise seeding of potatoes.

Full textAbstract:
The research was carried out in 1990-2020 in order to analyze the state and level of potato growing sub-sector development in the Russian Federation and in Kostroma region with further identification of priority areas for improving its efficiency for the production of high-quality seed potatoes. Over the past three decades, the potato industry of the country has undergone serious changes. During the period from 1990 to 2020, the area of potato planting in the Russian Federation decreased by 1935.4 thousand hectares, or by 62%, the gross harvest decreased by 11240.8 thousand tons, or by 36.4%.In 2020 the level of self-sufficiency in potatoes, defined as the ratio of products produced in the country to its domestic consumption, amounted to 89.2%, which is lower than the indicator established by the Food Security Doctrine of the Russian Federation by 5.8 percentage points. In Russia, leading agricultural organizations have appeared, working on innovative technologies of world standards and reaching record yields of 45...50 t/ ha. However, the average potato yield in the country remains one of the lowest in Europe – at the level of 17 t/ha. A significant factor in obtaining high potato yields is the use of high-quality seed material of the best varieties. Potato seed production is effective only in optimal soil and climatic conditions with the use of reliable methods of accelerated reproduction of virus-free material and prevention of re-infection with diseases. This problem is successfully solved by organizing special protected areas with favorable climatic and phytosanitary conditions for growing healthy seed potatoes. The Kostroma region, subject to the effective use of its geographical location, favorable soil, climatic and phytosanitary conditions, can take a leading position in the production of high-quality potato seeds.

The technological process of growing potato seed material begins with the acquisition of the source material and its accelerated reproduction to the required volumes. To include new perspective varieties and hybrids in seed programs, they must be released from a viral infection. Exemption from viruses is a responsible, time-consuming and costly process that requires professionalism, but in the absence of this stage, promising varieties cannot participate in the implementation of seed programs. Only in vitro, a material thoroughly assessed with regard to the presence of pathogens, the varietal typicality and severity of the main variety distinctive features can ensure the high quality of seed potatoes in basic seed production.

The potato yield, planned on the basis of calculated methods of fertilizer application, in practice can fluctuate over a wide range. Many factors influence the increase in the removal of nutrients and potato yields. One of the most important factors for potatoes, as a vegetatively propagated culture, is the quality of the seed material. The purpose of the research was to substantiate the algorithm for obtaining high potato yields on the basis of determining the influence on the productivity of quality factors of seed material, the background of fertilizers, irrigation, the use of chemical etchant and biologically active preparations. Experiments of Kortni and Nevskiy varieties were conducted in Laishevsky district of the Republic of Tatarstan. It was revealed that in gray forest soils under experimental conditions, the optimal background of fertilizers with the main application on the bog was N120P140K140, on irrigation - N100P120K120. Higher doses of fertilizers on irrigation and on the bog caused lower yields. The use of the Maksim chemical preservative on the bog in the arid conditions of the year increased productivity by 6.0 ... 12.0%, on irrigation - reduced by 18.0 ... 24.6%. Biologically active preparations increased productivity in moist soil by 14.0 ... 17.0%. The consistent increase in the yield of a healthy seed of Kortni variety occurred under the influence of factors: the quality of seed material - from 10 to 15.5 tons per hectare - by 55%, the background of fertilizers N100P120K120- from 15.5 to 26.3 tons per hectare - by 70% irrigation - from 26.3 to 54.0 tons per hectare - by 105.3%, treatment with zircon - from 54.0 to 61.5 tons per hectare - by 14%. Against the backdrop nutrition of N100P120K120, calculated to yield of 20 tons per hectare, with additional factors, a yield of 61.5 tons per hectare (+ 208%) was obtained. In the degenerate seed material of Nevskiy variety, the increase in productivity with the progressive use of factors occurred to a much lesser extent: from the quality of the seed material - from 10.0 to 12.0 tons per hectare - by 20%, the fertilizer background N100P120K120 - from 12 to 17.5 tons per hectare - by 46%, irrigation - from 17.5 to 23 tons per hectare by 31.4%. Against the nutrition backdrop of N100P120K120, calculated to yield of 20 tons per hectare, Nevskiy yielded 23 tons per hectare (+ 15%). The importance of seed quality is a key in obtaining high yields of potatoes. In healthy seed potatoes, with additional factors - irrigation, fertilizers, BAP - much higher yields are created, compared to the addition of the degenerate seed material under the same conditions. On the basis of the obtained results, the following algorithm for applying the factors for obtaining high potato productivity is recommended: healthy seeds + irrigation + fertilizers + biologics.

The aeroponic production of certified seed potatoes is a booming alternative for arid and semi-arid areas where fresh water is scarce and soil-borne diseases and nematodes preclude field production. Although widely used in aeroponics, nutrient-solution salinity effects have not been evaluated in potatoes. This study aimed to (1) establish the best of two nutrient solutions (Otazú vs. modified Furlani) at 20, 50, 100, and 150% of the crop-recommended dose for seed-potato production, (2) evaluate growth indexes to diagnose plant-N status, and (3) establish a prognosis for the yield of nuclear seed potatoes under aeroponics. At 21 days after transplanting, there was a significant correlation between the nitrate-N petiole-sap test and some of the parameters measured. The 4th leaf indexes correlated with yield parameters indicating that they can be used to prognosticate the final minituber yield. The best parameters to diagnose the N status in potato plants were: 4th leaf area, length, and dry weight (Otazú’s), SPAD, and 4th leaf area (modified Furlani’s). Although both nutrient solutions had similar nitrogen concentrations, Otazú’s nutrient solution at 100% of the recommended nitrogen dose had lower salinity than the modified Furlani’s solution and was the best to produce nuclear seed potatoes.

Potato is an important food and cash crop globally and faces many challenges in Pakistan. These challenges include issues with soil fertility, pest and disease pressure and shortages of high-quality seed potatoes. The scarcity of high-quality seeds is a massive hassle in Pakistan. Farmers in Pakistan, often reuse their seeds or obtain them from informal sources. This practice leads to increased seed quality deterioration and tuber-borne diseases, resulting in decreased yields. To address this situation, aeroponic techniques can effectively meet this challenge. Aeroponics is a novel technique for producing high-quality seed potato, aiming to address the challenge of seed production. Aeroponic techniques are commercially practised in many countries. Thus, in this review, we have highlighted the importance of aeroponic technology and how this technique can help uplift/boost up the seed potato production system in Pakistan. The overview concludes that aeroponic seed production offers numerous benefits, including improved yields, and resistance, even as keeping natural resources. Despite the challenges, the evaluation indicates that the implementation of aeroponic seed production technology in Pakistan may offers a promising and sustainable technique for seed potato production in Pakistan.

The aim of this article is to assess the competitiveness of domestic and foreign potato cultivars grown in the country and to analyze the use of certified seed potatoes by the producers. The agronomic and utility value indicators were adopted as the measure of competitiveness of varieties. It has been shown that table cultivars of polish breeding in relation to foreign cultivars have generally higher agrotechnical value and higher yields but at the same time in many characteristics they have lower utility value (for example the look of tubers). The rate of use of certified seed potatoes depends on the degree of marketability of particular potato production sectors. It ranges from just 6.4% in multidirectional production to 25% in table and starch potato production, up to 40% in the production of early table potatoes and for food processing.

Potato production is one of the key branches of crop production that determines the food security of Kazakhstan. The Republic needs over 800,000 tons of seed potatoes per year. In addition to seed potatoes, which are grown in Kazakhstan, about 30,000 tons of seed potatoes are imported annually, while about 80% of this volume is imported from the Netherlands through private companies [1]. In 2018, 193.0 thousand hectares were occupied under potatoes in Kazakhstan, while the gross harvest amounted to 3806.9 thousand tons. At the same time, the yield in 2018 was only 19.8 t/ha. While in neighboring Uzbekistan in 2018, the yield was 33.68 t/ha, the maximum yield in New Zealand in 2018 was about 50.41 t/ha[2]. It is known that one of the main reasons for low potato yield is low-quality seed material. In Kazakhstan, mainly after obtaining virus-free plants in vitro through meristem culture, minitubers are obtained from them in most technological processes; in rare cases, microtubers are obtained from meristem plants in vitro and then minitubers from them. Research has shown that the bioreactor can massively clone meristem plants and get full-fledged virus-free microtubules reducing a significant proportion of manual labor, thereby reducing the impact on the result of the human factor, reduce infections, and reduce labor costs and material costs.

To reduce the missing rate caused by the arching phenomenon of seed potatoes in the traditional seed boxes of cup-belt potato planters, a conical-shaped seed box comprising a seed-metering box and a reseeding box connected together was proposed. The method in this paper combined the discrete-element-analysis method and response-surface method and took the movement of the seed-potato group in the seed box as the research object. First, by analyzing the force and speed of seed potatoes, the main structural parameters affecting the seed-box seed-metering performance were determined, and the indices for evaluating the seed-box seed-metering performance were established. Additionally, a single-factor simulation test and orthogonal test were carried out for the main structural parameters of the seed box. Using the optimized structural parameters of the seed box, a trial conical seed box was produced, and bench-verification tests were carried out. The results showed that the multiple rate, missing rate and coefficient of the variation of the plant distance for the conical seed box were reduced by 4.76%, 4.0% and 9.18%, respectively. The research results have practical significance as guidance for improving the sowing performance of cup-belt potato planters. At the same time, the research results have reference value for solving the arching problem for granular materials in the box.

Full textAbstract:
The aeroponic plant root environment has a significant role in producing high-quality seed tuber potatoes. However, in lowland and tropical regions, the aeroponic system cannot yield high-quality potato seed because the average environment temperature year-round is high. In a high-temperature environment, the potato plant roots cannot optimally absorb the nutrient solution for healthy plant growth. This paper presents the method used to maintain the aeroponics root chamber temperature conditions. An air conditioning system was adopted to supply air with the optimal temperature range for mini-tuber potato seed cultivation. The vapor compression refrigeration type was applied in the air conditioning system. The root chamber temperature is controlled and monitored using an Arduino Uno board system. The mini-tuber potato seed cultivation field experiment results show the proposed method can maintain the aeroponic root chamber temperature. The root chamber temperature treatment operated in the 10 °C–20 °C range. This temperature range improved the potato seed tuber yield. The potato seed tuber yield potential is observed from the stolon number produced by the mini-tuber potato plants cultivated in the root chamber with the conditioned temperature. The field experiment reveals that the stolon number produced by potato seeds cultivated in the root chamber with conditioned temperature was up to 77% greater than the number of potato seeds cultivated in the root chamber with the unconditioned temperature.

The response of corn, beans and potato was evaluated in a 3 crop intercropping system at constant population density of corn (37,050 plants/ha) and three densities of beans (66,000 132,000 200,000 plants/ha) and potato (13,000, 36,000, 44,000 plants/ha) at low soil nitrogen in 2 seasons. Intercropping at the highest plant densities of beans and potatoes reduced the yield of corn, beans and potatoes by 65, 80 and 51 per cent respectively and produced a land equivalent ratio (LER) of one. The LER increased with decrease in the density of companion crops up to 1.24, indicating that intercropping at lower densities was more beneficial than monocultures. Increasing the density of beans and potatoes reduced corn height, leaf width and size of ears as well as leaf N, P and K. In beans the number of pods per plant was reduced while seeds per plant and seed weight were constant. In potatoes tuber size and numbers per plant declined.. The results indicate that the triple crop density which maximizes yield and income should not exceed 2/3 of optimum bean and potato sole crop densities.

Abstract Potato (Solanum tuberosum L.) is a staple food belonging to the three most important crops worldwide. In the recent five years, potato production in Indonesia tended to decline. One of the factors that cause the low productivity of potatoes is the limited availability of superior seeds. Micropropagation is the alternative to the conventional propagation of potatoes. The seed production technique of potatoes can be designed with in vitro multiplication through either plantlet regeneration or micro tuber production. This research aimed to investigate the effect of sucrose and potassium dihydrogen orthophosphate concentration on potato var Granola growth and development by in vitro. This research was conducted at the Plant Tissue Culture Laboratory, Proliteknik Negeri Lampung, from August to October 2021. Treatments were factorially arranged in a completely randomized design with three replications, each replication consisted of three culture bottles containing one explant. Data analysis using ANOVA and HSD test. The result of this research showed that the best growth and development of potato culture was obtained on media containing 340 mg.l-1 potassium dihydrogen orthophosphate and 60 g.l-1 sucrose.

This study focuses on the impact of pre-planting irradiation of seed potatoes on the phenophases of the root crop and proliferation of fungus Rhizoctonia solani on the new crop tubers. A two-year monitoring of seed potatoes after irradiation shows that treatment of tubers with 30-40 Gy decreases the spread of fungal infection on the surface of the tubers. It was found that low-energy electrons, used in the experiment, are the most effective irradiation treatment, since they penetrate in the upper layers of potato tubers affected by the fungus.

The work analyzes methods for creating initial material for virus-free potato seed production. Determined that, elites grown from healthy tubers using the apical meristem method have higher productivity than seed potatoes grown from starting material created by other methods. Installed that, with visual observation and serological analysis, in comparison with the control, the average plant height is 5 cm, the number of stems is 0.4, the absorption surface is 2.3 thousand m2 per hectare, virus infection in an obvious form is 1.5%, in a latent form - 4.4% less, with a yield of 3.7 t/ha. For example, during visual observation and serological analysis, the average height of plants was 84 cm, the number of main stems formed per plant was 4.4, and it was found that the absorbing surface was 34.9 thousand m2/ha per hectare. In the control variant, these indicators remained at the level of 79 cm, 4 pcs. and 32.6 thousand m2/ha, respectively. Based on a visual assessment of the initial buds and serological analysis, in the selected variant, only 8.25% of plants showed obvious symptoms of a viral disease, while in the control variant, these indicators showed symptoms of the disease in 9.7% of plants. It has been researched that, in the case of using buds treated by the meristem method, obvious symptoms of the virus were observed in 5.8% of plants, and in the control variant - in 9.7% of plants. In the case of using healthy buds using the triple meristem method, the level of plant infection with latent viruses was the lowest - 14.6%, while in the case when seed buds were selected only on the basis of visual assessment, this figure averaged 21.4%. That is, in addition to the currently used only visual selection of source material, it has been established that selection using serological tests reduces infection of plants by latent viruses by 6.8%. Research has shown that when growing potatoes from generative seeds, the greatest yield is obtained with the 1st reproduction of tubers obtained by this method. In this option, the yield per unit area is 31.2 tons. organized This result is explained by the fact that when potatoes are propagated by botanical seeds, viruses are not transmitted to offspring, and the concentration of infection in the first generation of such seedlings is low. Developed in research, that cultivating elite potato seeds from generative seeds of the crop can be an effective approach for generating seed stock for primary planting of potatoes, as seeds from 1-2 reproductions of tubers obtained in this way. confirms that it can be used.

. In 2021–2022, experiment on growing potatoes with preliminary seed tubers storage in the environment of the ethylene phytohormone was conducted at the Russian Potato Research Centre. The aim of the research was to determine the influence of seed tubers treatment with phytohormone ethylene on growth, development and yield of potatoes, taking into account the preplant doses of mineral fertilizers and variety specificities. Ethylene appliance at a concentration of 15 ml/m3 was carried out in the potato storage from November till the end of April at a temperature 4 0C and a relative humidity 90-95%. As a result of research, it was found that the use of ethylene while seed potatoes storing of varieties Grand and Vympel provided the 2-3 days earlier emergence of seedlings; an increase in plant height by 1.5-12.4%; an increase in number of stems per plant by 11.4-26.3%; an increase in leaf surface area by 5.5-11.3%. The total potato yield due to ethylene appliance increased by 5.6-12.9% or 1.3-1.8 t/ha (Grand) and by 5.6-27.7% or 1.1-3.6 t/ha (Vympel). The most significant increase of yield was noted when growing potatoes with mineral fertilizers dose N30P30K45. Ethylene seed treatment did not have a significant effect on the percentage of commercial tubers. The Grand variety, compared with the Vympel, turned out to be more responsive to the use of high doses of mineral fertilizers. It was found that the most significant factor that provided an increase in total yield by 4.2-12.4 t/ha or by 25.3-93.9% (depending on the variety and ethylene treatment) was the dose of fertilizers.

Pre-basic seed potatoes are disease free potato minitubers produced by transplanting pathogen free in vitro potato plantlets under protected condition in aphid-proof glasshouse and/or screen house. Double antibody sand witched - enzyme linked immuno-sorbant assay is used to test six major potato viruses, namely PLRV, PVS, PVX, PVY, PVA and PVM. Thermotherapy cum meristem tip excision techniques are used to eliminate these viruses. Virus free in vitro potato plantlets are rapidly propagated by single nodal cuttings on modified MS media. For pre-basic seed production disease free in vitro potato plantlets are transplanted in the sterile sand soil substrate under glasshouse and screen house, once in autumn season and next in spring season. Since 1990, National Potato Research Program has been producing about 200,000 pre-basic seeds annually. So far, PBS of 19 different recommended and released potato cultivars has been produced. Till date 3,465,799 PBS had been produced and 3,217,666 pre-basic seeds distributed to the different seed potato growers groups, District Agriculture Development Offices, government farms/research stations, and NGOs/INGOs for subsequent basic seed potato production.

Full textAbstract:
Mustard seed meal (MSM) derived from Sinapis alba controls weeds for several weeks following application to soil, but also has potential to injure the planted crop. Producers of certified organic potatoes typically utilize a combination of cover crops, soil hilling, harrowing, and cultivation for weed control. Once the potato canopy nears row closure, most late emerging weeds are suppressed by the dense potato canopy. MSM may have value for early season weed suppression in potato, but has not been previously tested. Our objectives were to determine the weed control efficacy and potato tolerance to MSM. We evaluated response of potatoes and weeds to MSM applied at 1.1, 2.2, and 4.5 MT ha-1 applied in a band on the potato hill just after a shallow harrowing and prior to potato emergence as part of an integrated weed management program in potatoes. MSM applied at 2.2 and 4.5 MT ha-1 reduced early season grass and broadleaf weed density 73 to 99% and 54 to 98%, respectively, in potato and reduced late season broadleaf weed biomass 71 to 94% in all three years tested. Early season grass weed density in potato was reduced by MSM at 2.2 and 4.5 MT ha-1. Late season grass weed biomass was reduced by the highest rate of 4.5 MT ha-1. MSM at 4.5 MT ha-1 caused minor injury to potato (3 to 15%) at 3 weeks after emergence, but did not reduce total tuber yields or percentage of US No.1 tubers. MSM could be a component of an integrated weed control program in potato.

Columbia root-knot nematode, Meloidogyne chitwoodi Golden et al. (1) was identified from potatoes, Solanum tuberosum L., collected from Dallam County, Texas in October 2000. Seed potatoes are the most likely source for this introduction. This nematode is currently found infecting potatoes grown in California, Colorado, Idaho, New Mexico, Nevada, Oregon, Utah, and Washington. Some countries prohibit import of both seed and table stock potatoes originating in states known to harbor M. chitwoodi. Lesions on the potatoes had discrete brown coloration with white central spots in the outer 1 cm of the tuber flesh. Female nematode densities averaged 3 per square centimeter of a potato section beneath the lesions. Nematodes were morphologically identified as M. chitwoodi based on the perineal pattern of mature females and the tail shape of juveniles per Golden et al. (1). Using polymerase chain reaction-RFLP of the rDNA ITS1 region and the mtDNA COII-16S rRNA region (2), individual juveniles were identified as M. chitwoodi based on their restriction fragment patterns. This is the first report of Columbia root-knot nematode infecting potatoes in Texas. The distribution of this nematode in potato fields throughout central United States should be determined.

The research was conducted for potato cultivation in Lesser Poland. In order to determine the environmental impact with the LCA method, the SimaPro application was used, ver. 8.1.0.60. The “cradle-to-gate” approach was adopted, taking into account the type of technological practices, as well as machines, duration of their operation, number of seed potatoes, fertilisers, pesticides, used fuel and water. The final results were referred to the area of cultivation (1 ha). It was, for instance, found that one of the greatest impact factors of potato cultivation affecting the natural environment is the use of seed potatoes and relatively high consumption of diesel.

Abstract Potato is an essential crop in Bali. The potato productivity in Bali is still low compared to other provinces in Indonesia. The main problem is difficulties in obtaining quality seeds at affordable prices. This study aimed to ensure the survival of tissue culture seedlings during acclimatization and produce good quality early-generation seed potatoes. The research was conducted at Batusesa Village, Tabanan, Bali, from March - July 2021. There were two experiments, the first was the production of G0 seed potato, and the second was the production of G1 seed. Production of G0 was done using Factorial Randomized Block Design with two factors, variety (Granola and Vega) and media (charred rice husk, charred rice husk + coco peat, charred rice husk + coco peat + soil). Each treatment combination consisted of 100 cuttings. Variables observed were harvest time, tuber weight, and total tubers per plant. The result shows that Vega has a shorter harvesting time (65 days) compared to Granola (70 days). Vega produced heavier tuber in all media trials. Granola made more tubers in M3 media. Experiment on G1 production was done using Randomized Block Design with two factors, variety (Granola and Vega) and G0 seed tuber size (<15 gram and ≥ 15 gram; <50 gram and ≥ 50 gram). Vega produced more tubers than Granola; while Granola produced bigger tubers than Vega. Bigger seed tubers had the highest tuber production and bigger size tubers in both varieties.

Utilizing a mid-altitude area for potato cultivation is one of the solutions to increase potato seed production. This study aimed to compare the growth and production of IPB CP1 G0 seed tuber in a greenhouse and screenhouse in mid-altitude with different numbers of shoot cuttings per polybag. This research was conducted with two factors. The first factor is the use of growth plant houses, i.e. greenhouse and screenhouse. The second factor is the number of shoot cuttings per polybag, i.e. 2 and 3 shoot cuttings per polybag. Growth parameters observed included plant height, number of nodes and leaves, and fresh and dry weight of shoots. The production parameters observed included the number as well as fresh and dry weight of tubers. The growth and production of IPB CP1 potatoes grown in the greenhouse were better than those grown in the screenhouse. The number of cuttings per polybag did not affect the growth and production of IPB CP1 potato.

The examinations of potatoes original seed nursery in north regions of Ukrainian marshy woodlands in 2012 (47 sorts) were performed. It was revealed that spreading of viral infection and diseases symptoms onset on potatoes cultivars increases with the number of field reproductions from 8,1 % (tube plants – seedlings) to 77–100 %. The wide-spreading of latent infections was observed – 57 % of tested samples. Potato virus М prevails in plantings as monoinfection (36,2 %) or in complex with other mosaic viruses (99 %), Potato virus Y was detected in 38,3 % of cultivars, with domination of necrotic isolates. The need of efficient protection and constant viral control of seed material with the use of laboratory methods and modern diagnostic facilities is emphasized.

Potato virus Y (PVY) is among the most economically impactful potato pathogens, yet the spread of PVY from infected seed potatoes within commercial potato fields has not been adequately studied. Test lots containing various seed-borne PVY levels were created by mixing different proportions of seed pieces from healthy and infected tubers drawn from the same seed source. These seed lots were planted in commercial potato fields near the Teton Seed Potato Management Area from 2010 to 2012. Regression analyses on data from these test plots produced models of the in-season spread of PVY originating from infected seed. Conventional ordinary least squares techniques were supplemented with the use of quantile regression; the resulting models indicate the significance of seed-borne PVY on end-of-season infection levels and highlight the need of seed potato buyers to review postharvest testing results.

Full textAbstract:
Throughout the world, potatoes, as a food crop, are very important. One of the main reasons for the poor quality of planting material, yield and potatoes themselves are viral infections. The use of virus-free seed material is one of the high-potential ways to increase the yield and efficiency of potato production. Aeroponics is a promising direction in obtaining a virus-protected crop. This study aimed to assess the potential and improve the technology for growing healthy mini-tubers of potatoes using the aeroponic method, which is a safe and economical method. Compared to the usual method of growing crops, aeroponics assumes lower water and energy costs per unit of production, as well as excludes soil diseases of the plant and does not allow damage to the tuber caused by pests. For growing different varieties of crops in different regions, artificial conditions such as additional lighting in greenhouses can be easily provided. In this study, economic calculations have shown that, from a practical point of view, Aeroponics technology may be appropriate for large-scale production of seed potatoes.

<p>Sistem perbenihan kentang yang ada saat ini terdiri atas lima kelas benih, yaitu G0, G1, G2, G3, dan G4. Kelas benih G0 sampai G3 merupakan benih sumber, sedangkan kelas benih G4 merupakan benih sebar. Banyak penangkar, petani maupun stakeholder lainnya berpendapat bahwa proses produksi benih kentang dari kelas G0 sampai G3 cukup lama sehingga penyediaan benih untuk kentang konsumsi (G4) tidak dapat dilakukan secara cepat. Kegiatan penelitian bertujuan untuk mengetahui tingkat produktivitas kentang masing-masing kelas benih G0 sampai G4 agar dapat direkomendasikan sebagai kelas benih untuk kentang konsumsi. Penelitian dilakukan di Kebun Percobaan Margahayu Balitsa Lembang dari bulan September sampai November 2012 menggunakan rancangan acak kelompok dengan enam perlakuan, yaitu kelas benih (G0, G1, G2, G3, G4, dan kontrol) dan empat ulangan. Parameter yang diamati meliputi pertumbuhan tanaman, produksi, dan mutu produk. Hasil penelitian menunjukkan bahwa kentang yang berasal dari kelas benih G3 menghasilkan produksi dan kelas umbi A dan B yang tertinggi sehingga cocok untuk benih sebar. Untuk peningkatan produksi ternyata kelas benih yang lebih tinggi (G0 dan G1) memiliki peningkatan produksi dan menghasilkan umbi kelas C dan D yang lebih tinggi daripada kelas benih di bawahnya sehingga cocok dikategorikan sebagai benih sumber.</p><p>Potato seed systems that exist today consists of five seeds classes, namely G0, G1, G2, G3, and G4. G0 to G3 seed is the source seed, while classes G4 seed was extension seed. Many breeders, farmers and other stakeholders argue that the process of seed production from G0 to G3 class was too long so that the supply of potatoes seeds for consumption (G4) could not be carried out faster. Research was conducted to determine the level of productivity of each class of potato seed G0 to G4 to be recommended as a seed class for potato consumption. The reseach was conducted at Margahayu Experimental Garden of Indonesian Vegetable Research Institute Lembang from September–November 2012 in randomized block design with six treatments : seed class (G0, G1, G2, G3, G4, and control) with four replications. The parameters observed were plant growth, production, and product quality. Hence, it can be concluded that potatoes derived from G3 class was quite suitable for extension seeds. The higher the seed class (G0 and G1) the higher the increasing rate and it produced higher number of C and D tuber grade.</p>

The article presents the results of conducting primary seed production of virus-free original and zoned potato varieties in the conditions of Northern Kazakhstan. The creation and introduction into the production of new virus-free highly productive potato varieties with a complex of economically valuable traits is a priority for the national economy of any state. Providing potato-growing farms with high-quality seeds of local varieties has been and remains an acute problem for the industry. The data on the yield and quality of tubers depending on the reproduction of potatoes are presented. So, when assessing the yield of virus-free potato varieties, a good indicator was observed in Dunyasha (12.7 t/ha), Zeren (9.2 t/ha), and Sante (6.4 t/ha). When harvesting from an area of 0.6 ha, 3.4 tons of super-elite potatoes were harvested with an average yield of 5.7 t/ha.

Full textAbstract:
Utilizing innovative agricultural practices that enhance the nutritional quality of staple foods such as potatoes provides farmers with tools to successfully meet the challenges of feeding a rising global population while sustaining organic food production. In the present study, we have demonstrated the potential of white mustard (Sinapis alba) seed meal extract to improve potato nutritional properties. Sinapis alba extract is a low-cost by-product of mustard oil extraction that contains a relatively high concentration of biologically active compounds. When applied to soil, S. alba extract had a positive impact on nutritional quality of potatoes. For example, total phenolic content in potatoes treated with S. alba extract increased by ~1.5 times, and potato nitrogen content increased from 1.52% to 1.73% with one application of S. alba extract. At the same time, application of S. alba extract had limited impact on the accumulation of anti-nutrients such as glycoalkaloids in potato tubers. The ability to boost the phenolics content of potatoes by applying an organic amendment is a valuable tool in organic farming as it creates more nutritional crop. To the best of our knowledge, this is the first study to examine the effect of S. alba extract on the nutritional quality of potatoes, or indeed of any food crop.

Root-knot nematodes are considered as one of the most destructive pathogens of potatoes, especially on tuber seed. Infected potato seed will cause tuber malformation and the most important thing is as the main spreading source of Meloidogyne spp. The objective of this research was to know the prevalence and identify the species of root-knot nematode which attack the potato seed in four sub-districts of potato production centre in Central Java, Indonesia. Molecular and morphological identification was conducted for the nematode species identification. PCR assay using MIG primer to detect three tropical root-knot nematodes followed by sequencing was conducted for molecular detection, while the perennial pattern was conducted for morphological detection. Results showed that root-knot nematodes on potato seed were generally distributed in Central Java with the prevalence percentage between 14.28-88.23% on the three from four sampling area. The molecular and morphological identification show that species of root-knot nematodes identified on potato seeds were Meloidogyne javanica, M. incognita, and M. arenaria.
