The implementation of potato potential yield (30-40 tons per hectare) in the forest-steppe zone of the Middle Volga is possible with the introduction of highly adapted varieties, the use of evidence-based farming cultivation. The authors studied the efficiency of promising new varieties of potatoes on gray forest soils in the Republic of Tatarstan. It was founded that when treating by calculated dozes of fertilizer potatoes of Rozhdestvenskiy, Impala, Sprint, Feloks, Red Skarlet varieties on gray forest soils of the Middle Volga steppe on average for three years the planned harvest tubers 40 or more tons per hectare was formed. The yield of Aroza, Nevskiy, Adretta varieties was 36,51-37,30 tons per hectare. In the more favorable moisture 2009 year, the high yields of tubers were formed by varieties: early-maturing Impala (58.35 tons per hectare), Red Skarlet (57.02 tons per hectare), Feloks (55.83 tons per hectare), middle-maturing Adretta (57,22 tons per hectare), Rozhdestvenskiy (56.13 tons per hectare). In drought 2010 year, in the application of irrigation higher yields of tubers formed early-maturing varieties: Sprint (21.52 tons per hectare), Red Skarlet (21.06 tons per hectare), Impala (20.59 tons per hectare) and Aroza (20.53 tons per hectare) and middle-maturing variety Nevskiy (21.74 tons per hectare). Less yields in 2010 were such varieties as Adretta - middle-maturing (14.58 tons per hectare) early-maturing Rokko (13.67 tons per hectare). The difference in yield of these varieties in this year reached 7.16 tons per hectare, the higher yield more than 20 tons per hectare was provided by 5 species of 9 studied (20,53-21,74 tons per hectare).

The authors showed that in Kazakhstan northern region grain harvesters of 4, 5 and 6 classes did not provide the required level of productivity due to low yields. Longer harvesting period increased product losses. It was found that the harvesting machines were working in the incomplete loading mode of the thresher. The authors revealed the discrepancy between the standard sizes of the used reaping machines and regional zonal features.(Research purpose) To substantiate the parameters of headers and reaper-headers for combine harvesters in the incomplete loading mode of the thresher.(Materials and methods) The authors performed technical and economic calculations according to the criterion of operating costs for direct combining with a yield of 0.5 to 2.5 tons per hectare. The calculation was carried out for combine harvesters Vector-410 (class 4), Acros-550 (class 5), Essil-760 (class 6), aggregated with headers of different working widths.(Results and discussion) The authors determined that for the combine Vector-410 the rational width of the header was 9 meters in the yield range of 0.5-1.5 tons per hectare, and with a yield of 2.0-2.5 tons per hectare – 7-9 meters. For the combine Acros-550 the rational width of the reaper-header was 16 meters with a yield of 0.5-1.0 tons per hectare, with 1.5 tons per hectare - 9-12 meters, and with 2.0-2.5 tons per hectare – 7-9 meters. For the combine Essil-760 these values were 16; 12 and 9 meters respectively.(Conclusions) It was found that when comparing grain harvesters of 4, 5 and 6 classes with a yield of 0.5-2.0 tons per hectare, the lowest operating costs were provided by Acros-550 and Essil-760; with a yield of 2.0 tons per hectare - Vector-410; with a yield of 2.5 tons per hectare the Acros-550 was more effective.

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.

In modern conditions, one of the priority directions of potato growing is the selection of new highly productive varieties, resistant to the action of abiotic and biotic factors. When potatoes are cultivated, the optimization of mineral nutrition and the depth of planting of seed tubers is an important factor for obtaining sustainable yields. The experiments were laid on gray forest medium loamy granulometric composition of the soil of the forest steppe of the middle Volga region. It was established that the highest yield - 52.50 tons per hectare was formed when fertilizer doses (manure 50 tons per hectare + N135-153P135-145K179-184) were calculated for 50 tons per hectare of tubers, when planting to a depth of 8-10 cm. On tte background fertilization in a dose of manure 50 tons per hectare + N120P120K140 when planting at the same depth yield was 49.50 tons per hectare. On the variant with a planting to a depth of 6-8 cm, the yield of tubers was to 2.89 and 2.92 tons per hectare lower.

The article presents the results of a long-term analysis of the organization of the crop rotation system, saturated to varying degrees with grain crops in comparison with the permanent cultivation of winter wheat, barley and also permanent clean fallows on the gray forest soil of Kama region of the Republic of Tatarstan. Crop rotations with clean and occupied fallows were studied: pure fallows-winter rye - spring wheat; vetch-oat mixture - winter rye - spring wheat; peas for grain - winter rye - spring wheat. The accounting area of the plots was 800 m2. The experiment was repeated three times; the options were randomized. The experience is based on two backgrounds of fertilizers: medium and high. Fertilizers were calculated by the calculation and balance method for a given yield. For the average background, the given pea yield per grain was 2.0 tons per hectare, vetch-oat mixture per green mass - 20.0 tons per hectare, winter rye - 2.5 tons per hectare. For an increased background, pea yield per grain was set at 3.0 tons per hectare, vetch-oat mixture per green mass - 28.0 tons per hectare, winter rye - 3.0 tons per hectare. A relatively high yield (3.7-3.9 tons per hectare) of pure steam on calculated fertilizer backgrounds was achieved due to uniform seed placement (91.9%), good field germination (85.4-88.4%) and more intensive growth and development of winter rye. However, it should be emphasized that the yield of winter rye in occupied pairs is not inferior to the yield in pure fallows in years with optimal moisture.

Research was conducted to study the reaction of early varieties of Bellarosa potato to the application of calculated fertilizer doses and planting density in the conditions of the forest steppe of the Middle Volga region. Experiments were laid in 2012-2015 on gray forest soil of medium loamy granulometric composition, on the experimental field of the Transcaucasian Republic of Tatarstan. The article presents the results of 4 summer studies. It was established that the average yield for the 4 years was 41.17 tons per hectare, with a planting density of 66.6 thousand tubers against the background of nutrition, calculated to produce 40 tons per hectare. The introduction of calculated fertilizer doses for a potato yield of 30 tons per hectare, depending on the planting density, increased the productivity of tubers to 8.17-10.96 tons per hectare. The highest yield against this background – 31.18 tons per hectare on average for 4 years was formed at a density of planting 66,6 thousand pieces per hectare. It should be noted that the introduction of calculated fertilizers at this yield level increased the efficiency of increasing the density of planting, where the yield increase from this intake was 4.22 and 5.81 tons per hectare. The effectiveness of increasing the density of planting with a further increase in the background of nutrition was not so high. So, against the background of fertilizers calculated for yield of 35 tons per hectare, the increase from the increase in the density of planting to 60.6 and 66.6 thousand, compared to 55.5 thousand pieces per hectare, was 1.62 and 2.62 tons per hectare. Against the background, calculated for harvesting 40 tons per hectare on average over 4 years, an additional 1.60 and 2.90 tons per hectare of tubers were obtained.

The article presents the results of studies on the effect of nutritional background on productivity and quality of spring soft wheat seeds of Yoldyz variety. The agrometeorological conditions of the growing season had a decisive influence on the harvest of spring wheat. In more favorable weather conditions in 2017 and 2018 years, the difference in yield compared to the dry 2016 was 0.4-0.42 tons and 0.48-0.59 per hectare on fertilized backgrounds. The use of calculated rates of fertilizers for 3 tons per hectare of grain contributed to an increase in yield of 0.55 tons per hectare. A further increase in the fertilizer dose to obtain 4 tons per hectare of grain did not give a significant increase to the fertilizer background of 3 tons per hectare. The level of mineral nutrition has improved the seed sowing qualities. With an estimated nutrition level of 3 tons per hectare, on average for three years, the seed germination energy increased by 4.8% compared to the control, on the 4 tons per hectare variant - 5.2%, laboratory germination, respectively, by 1.8-1, 4%, growth rate - 4.1-5.7 percent. Seeds grown on fertilized backgrounds per 3 and 4 tons per hectare of spring wheat grain had increased yield properties. The yield increase to the control was 0.67-0.75 tons per hectare. Under the conditions of gray forest soils of Kama of the Republic of Tatarstan, spring wheat of Yoldyz variety should be grown on seed crops at the background of the application of calculated norms for fertilizers of 3 tons per hectare of grain.

The study of growth regulators efficiency in the cultivation of early-maturing potato of Red Scarlett variety was conducted on gray forest soil of Kama of the Republic of Tatarstan. The reaction of the new early maturing potato of Red Scarlett variety was examined, when assessing ways to use drugs Silk and Albit (soaking seed tubers, foliage cultivation, combined processing (tuber + foliage twice). It was found, that the use of growth regulators of Silk for the treatment of tubers before planting, depending on the nutrition background, increased the productivity tubers to 2.33 – 3.32 tons per hectare, Albit drug application increased the harvest to 1.55-1.70 tons per hectare. Foliar treatment by Silk twice during the growing season has increased the yield by 3.31-4.05 tons per hectare, by Albit by 2.30-3.16 tons per hectare. When complete machining (tubers + tops) respectively by 5.18-7.16 and 4.16-5.20 tons per hectare. The most efficient option was at the processing of tubers + twice vegetative plant with growth regulator Silk in the background of calculated dozes applicant, rated on the tuber yield of 30 tons per hectare, when yield increase was 7.16 tons per hectare.

The article presents the results of research conducted in different soil and climatic conditions of the Middle Volga region on the influence of regulated factors, as well as environmental factors on the production process of plants of various types of spring wheat. The amount of photosynthetically active radiation (PAR) is enough to obtain yields within 12–13 tons of dry biomass or 6–7 tons of grain. Natural precipitation is able to provide 3.82–4.36 t of spring wheat grain from 1 ha, and 4.5–6.3 t/ha by the total influence of solar energy, heat and moisture supply. Natural level of soil fertility without application of organic and mineral fertilizers allows to receive about 2 tons of spring wheat grain from 1 ha. Application of nitrogen in the form of ammoniac water (N-20.5 %) increased the yield in comparison with the use of nitrogen in the form of ammoniac saltpeter: the increase was 0.14 t per 1 ha. In the conditions of grey forest soil in the Predkamye region of the Republic of Tatarstan the optimal norm of sowing of spring wheat Triticum dicoccum Schuebl (spelt) depending on the feeding background was established. Growth of yield at sowing of 6 million seeds per hectare at all levels of nutrition in comparison with sowing rate of 4 million tons per hectare was 0.18 tons per hectare against the natural background, against the estimated background of NRC on 2.0 tons of grain – 0.19 tons and 2.5 tons of grain – 0.24 tons per hectare. The maximum yield increase was received at a combination of a mineral foodstuff with an optimum norm of sowing and has made on a settlement background 2 tons of grain from hectare – 0.20 tons, on 2.5 tons of grain – 0.34 tons from hectare. Thus, the aim of our research was to develop methods of growing high yielding quality grain of different types of wheat adapted to the conditions of forest-steppe in the Volga region.

The studies were carried out to determine the effectiveness of applying calculated doses of fertilizers to the planned potato tuber yields of the early-ripening Molly and Colette group in the conditions of the forest steppe of the middle Volga region. The influence of mineral nutrition backgrounds, calculated on obtaining tuber yields of 25, 35 and 45 tons per hectare in comparison with the unapproved control, has been studied. The analysis of the leaf area dynamics of potato plants, the parameters of the leaf photosynthetic potential, the coefficient of photosynthetically active radiation factor showed that these indicators of photosynthetic activity are directly dependent on the level of mineral nutrition. Against the background of natural fertility, the Molly variety produced 16.76 tons of tubers per hectare and 18.32 tons of the Colette variety. Fertilizers, calculated for 25-45 tons of tubers per hectare, ensured the formation of Molly 28.23-43.57 t ons per hectare, Colette - 29.72-42.54 tons per hectare. The introduction of calculated doses of fertilizers at 25 and 35 tons of tubers per hectare did not result in a significant decrease in the starch content in the tubers, and the doses that were calculated for a yield of 45 tons per hectare increased the amount of nitrates and reduced the starch content in the tubers.

The aim of the thesis was to design the transformation of production using the simplex algorithm. My thesis is focus on the transformation of the original Bachelor thesis, for which I created the initial production of the holding, with a focus on plant and animal production. The transformation concentrates on the conversion of the milk's production to production focused on breeding cows without market milk production. The base stone was redoing the plant production. Plant production has been used not only for the production of custom feeding, but for the sale of plant commodities on the market to increase profits. The new production focuses on the cultivation of the crop production purely for their own consumption as feed for livestock. All profits create livestock production. The intention was therefore to transform the plant and livestock production, so as to obtain the most effective new way to use areas, for a change of the production.

Crop physiology has been called “the retrospective science” by one plant breeder because we physiologists elucidate what the breeders have already achieved. Indeed, such explanations occupy the first part of this chapter, the whence of greater crop production. We shall also peer ahead, the whither in my title. But physiologists have learned that past increases in crop productivity have often come from unexpected and initially unrecognized directions, in many cases driven by developments in agronomy, mechanization, and demand. The integrating power of empirical selection for yield potential has, so far, proved more effective than ideological selection for specific physiological characteristics, presumably because yield is the integrated end result of a great variety of processes that must act in a balanced and coordinated way. Crop production can be increased in several ways, such as by extending the arable area, by increasing yield per hectare per crop or the number of crops per hectare per year (called intensification), by displacement of lower by higher yielding crops, and by reducing postharvest losses. Until the 1960s the major contribution for the world as a whole came from increases in the area of arable land and in the proportion of it under crop. Since then, however, the limited increases in arable area, in South America and Africa mostly, have largely been matched —though not in land quality —by losses to urbanization, transport, and degradation. The proportion of rainfed arable land under crop continues to increase slowly, currently being about three quarters for the developing countries as a whole. The intensification of arable land use is most important in warmer and wetter climates, particularly under irrigation. Double cropping of rice has been prominent in China since Sung times. Cropping intensity in the Punjab now approaches 200%, and FAO projects that 13% of the increase in crop production in developing countries by A.D. 2010 will come from intensification, compared with 21% from extension of the arable (Alexandratos, 1995). Further intensification will depend heavily on extension of the irrigated area, but much can also be achieved by the breeding of earlier maturing varieties coupled with improvements in fertilizer use and minimum tillage procedures.

<em> Abstract.</em>—Tilefish stocks along the Atlantic coast of the United States have a history of rapidly becoming overfished. Since 1916 when the unexploited southern New England– mid-Atlantic stock yielded 4,500 metric tons (mt), there have been three 20- to 25-year cycles of rapidly increasing landings followed by equally rapid declines to very low levels of catch. Landings have exceeded the long-term potential yield (approximately 1,200 mt) during each of the periods of high catches, especially from 1977 and 1982 when the fishing mortality rate was three times that necessary to obtain maximum yield per recruit.

Bio-organic agriculture considers the medium- and long-term impact of agricultural interferences on the agro-ecosystem. It aims to produce food while setting an ecological balance to soil fertility. Bio-organic agriculture takes a proactive design as opposed to treating problems after they emerge, so the study was conducted for studying two factors: First: the cultivars (Riviera and Arizona) class A resulting from cultivation of class E imported and cultivated in spring season 2018. The second factor: fertilizer combinations (bio-organic fertilizers compared with traditional chemical fertilizers). Arizona cultivar significantly achieved the highest values, in most of the study parameters compared to Rivera cultivar. Significant differences were observed between the treatments of fertilizer combinations, the treatment (organic fertilizer + bio-fertilizer + 25% chemical fertilizer) significantly achieved the best values compared to the control. Bi-interaction treatment (Arizona cultivar + organic fertilizer + bio-fertilizer + chemical fertilizer 25%) achieved the highest yield per hectare (43.24 tons.ha−1).

This chapter used nonparametric methods to establish the parameters of cash crop insurance contracts based on zone yields. The secondary historical yields data obtained from the Food and Agriculture Organization of the United Nations, for the period of 1961 through 2018, for cotton and cashew nuts, were used both in estimating the kernel density function and forecasting the mean yield. The estimated kernel density and mean forecasts were used to tabulate, at a different level of coverage, the probability of loss, the expected yield shortfall (kilogram per hectare, denote kg/ha), and the actuarial-fair premium rates for each crop. The results showed that, at different levels of coverage (i.e., from 50% to 90%), the actuarial-fair premium rates range between 0% and 32% of the sum assured. However, the range for cashew nuts is narrow (0% to 8%) while that of cotton is 4% to 32%, a very wider range compared to cashew nuts. Further, the expected losses for cotton, in the same coverage intervals, ranges from 11.58kg/ha to 256.06kg/ha while that of cashew was 0.44kg/ha to 19.69kg/ha.

Cotton, a crop of choice, occupies the second premier position next to food crops in providing clothing. Though 53 species of Gossypium are available, only four species are cultivable and among the four, the major cultivable area falls under G. hirsutum. Though varieties with medium, superior medium, long and extra long staple cotton were released earlier, with the advent of machineries, ginning facilities, mills were literally requiring cotton fiber of any length. With the advent of Bt technology and the release of hybrids during 2002, cotton productivity had a momentum. However, considering the duration, cost involved in manual harvesting etc., farmers were looking for alternate option and High Density Planting System (HDPS) offered a promise in this direction. Farmers were looking for genotypes that could yield better under higher planting densities with fewer bolls per plant, synchronized maturity with uniform bursting. Efforts have been taken all over the World in this direction and India is not an exception. Handful of varieties fitting to this situation has been released from many of the Universities. This chapter essentially summarizes the genetic, agronomic, plant protection interventions and the futuristic requirements for achieving at least 700 kg of lint per hectare.

Over the last decade, there have been massive investments and research to improve rice yield per hectare. Alongside successful stories of improved rice yields are corresponding concerns stemming from pre- and post-harvest rice quality- and safety-related issues. Such concerns in rice production, handling, and storage systems present public health and economic problems. To consumers and producers, a serious concern is the potential growth of toxigenic fungi on rice during storage leading to contamination of the rice with mycotoxins. That withstanding, diminished functional, sensory, and nutritional attributes hugely impact the investment returns. The author understands that discourse on rice storage is incomplete without reflections on nutritional related losses. In rendering a strong chapter to meet a wider readership, the above issues are discussed with deliberate effort to highlight technological advances making headway in the rice industry; these are outlined in the introduction, at first, and then expounded on in subsequent sections.

Despite of increasing areas of short rotation willow plantations in Lithuania, only few studies have been done so far regarding the biomass production in these plantations. To fill this gap, the aim of this study was to develop biomass equations for fresh and for oven drywillow biomass and to estimate the yield of short rotation plantations as expressed in fresh and oven dry biomass. The data required by this study was gathered in the western part of Lithuania, in the Šilutė and Tauragė regions. For this purpose, sample plots were established in 21 short rotation willow plantations managed by “Klasmann-Deilmann Bioenergy“. All of them were first rotation plantations grown for 3 to 4 years. It was found that mean annual oven dry biomass increment varied in these plantations from 0.2 to 7.6 tons per hectare per year. Surprisingly, the productivity was not related to soil fertility. Additionally, the relations between stand level values were evaluated and a stand biomass yield model based on the mean height was developed. Relations on the shoot level were analysed as well. As a result we developed biomass models based on the individual shoot diameter for shoot height as well as for fresh and for oven dry biomass.

Rapid depletion of conventional sources of energy and the growing environmental concern of their use warrant urgent attention to look for suitable energy alternatives. In this regard the seeds of Jatropha curcas, constituting 40–50% bio-crude oil are considered as one of the most promising alternatives for the production of bio-diesel. It is estimated that about 1.5 tons de-oiled cake is produced from seeds obtained from one hectare of plantation, utilized for bio-diesel extraction process. Being non-edible due to its toxic contents, cost effective safe disposal of this by-product can only be possible if there is a meaningful utilization. India’s tobacco industry is the second largest in the world after China, having vast area under tobacco cultivation. The wastes from tobacco industry lead to significant environmental pollution that has severe impacts on both flora and fauna. A few studies on this aspect have revealed that Jatropha and tobacco bio-wastes have potential to be used as organic fertilizers. The present study aims at developing appropriate bio-processes and formulation that utilize Jatropha seed cake and waste of tobacco industry as organic fertilizer for improving the growth of Chrysanthemum, a flower variety valued for its beauty and fragrance and having wide applications in cosmetic and perfumery products. Pot experiments were carried out by adding specific proportions of Jatropha de-oiled cake and tobacco waste to normal garden soil. The growth and morphological parameters of Chrysanthemum plants grown in pots prepared by the treated soil were monitored for 4–5 months and the results were recorded. The results have been encouraging as the treatments lead to a significant enhancement in flower growth as well as yield. 11.5% increase in number of buds per plant was recorded for treated soil as compared to the control soil. The number of flowers per plant also recorded an increase of 16% to 24% due to the effect of formulation applied to the soil. Similar trends were observed for other parameters like flower size, flower head size, flower weight and ray floret number. Through experimentation new composted organic fertilizer formulations, tailored to specific commercial crop has been developed. The research findings would enable these bio-wastes to be used as a viable alternative to the energy intensive chemical fertilizers for floriculture, thus contributing to the mitigation of global climate change. This addition in the value chain would improve the financial viability of bio-diesel extraction process. This new synergistic organic fertilizer formulation when used as an alternative to nitrogenous chemical fertilizers would also provide an opportunity to earn carbon credits which is estimated to be € 67904 millions/year.

We studied the cellulolytic activity of the winter wheat rhizosphere soil in a stationary field experiment with the application of mineral nitrogen-phosphorus fertilizers (N15P23 per hectare of crop rotation area), straw, and seed inoculation. We estimated the crop yield depending on the intensity of cellulose decomposition in the soil. We established that the intensity of cellulose decomposition in the rhizosphere of winter wheat was most affected by the application of mineral fertilizers, as well as the combination of the application of mineral fertilizers, straw, and seed inoculation with the biopreparation rhizoagrin before sowing.

Research results include the study of grain productivity of maize hybrids of three groups of ripeness against the background of fertilizer usage in autumn, nitrogen dressing in spring, and plant density. In the arid 2018, top dressing against the background without fertilization in autumn was more effective; in 2019, early ripening hybrid ‘Krasnodar 194 MV’ provided maximum yield at a rate of 6.05 t/ha when N30P30K60 fertilization was carried out in autumn and N30 top dressing in spring. The average yield (6.30 t/ha) provided early ripening hybrid when plant density was 70 thousand per hectare and fertilizer levels reached N60P60K60. Mid-season hybrid ‘Krasnodar 377 AMV’ under similar plant density and a half-dose of fertilizer led to obtaining maximum yield (7.67 t/ha).

The dominant technology for large Waste-to-Energy (WTE) facilities is combustion on a moving grate of “as-received” municipal solid wastes (MSW). However, there are circumstances where a low-capacity plant (<100,000 tons per year) is required. This study examines the technical, economic, and environmental aspects of some small-scale WTE technologies currently in operation. The Energos technology was developed in Norway, in order to provide relatively small communities with an economically efficient alternative to mass-burn incineration with equally low emissions to the atmosphere and flexibility in feedstock. All operating plants treat MSW plus additional streams of commercial or industrial wastes. Prior to thermal treatment, the materials are shredded in a high-torque, low-rpm shredder and ferrous metals are removed magnetically. The feedstock is partially oxidized on a moving grate in the gasification chamber where the fixed carbon is completely burnt off. The volatilized gases are fully combusted in a second chamber and the heat is transferred to a heat recovery system for steam generation. The Energos gasification technology is currently in operation at six plants in Norway, one in Germany, and one in the UK. As expected, the capital cost per ton of annual ton of capacity increases with decreasing plant capacity, while there is a linear relationship between energy recovery and capacity. Some other small-scale technologies are investigated in this study and will be reported at the NAWTEC meeting. Low capacity (<80,000 tons) WTE facilities require a relatively small footprint (1.5 to 2 acres; <1 hectare) and it is believed that these facilities can be built at a capital cost per ton that is as low, or lower, than that of large mass burn WTE facilities.

Optimization of planting dates and plant density for maize cultivation for green fodder is of particular importance under increased aridity in the Republic of Crimea. The aim of the research was to identify optimum planting dates and plant density for maize hybrids for green fodder harvested at the late milk stage under rain-fed conditions of the steppe zone of the Crimea. In the course of the experiment, we found that for the period from 2016 to 2019 yield of green fodder depended on the hydrothermal conditions of the year and plant density, as well as we observed the interaction of planting dates and conditions of the year. The optimum plant density was 70 thousand plants per hectare. On average, the yield of green fodder of early-ripening maize hybrid ‘Nur’ was 19.58 t/ha; medium early hybrid ‘Mashuk 220 MV’ – 19.25 t/ha, medium ripening hybrid ‘Mashuk 355 MV’ – 21.3 t/ha.

The phenotypic analysis of new candidate varieties at multiple locations could provide information on the stability of their genotypes. We evaluated the stability of 11 maize hybrid candidates in five districts in East Java Province, Indonesia. Maize hybrids with high yield potential and early maturity traits derived from a diallel cross were planted in a randomized complete block design with two checks (Srikandi Kuning and BISI-2) as a single factor with four replicates. The observed traits were grain yield per hectare and harvest age. The effects of environment, genotype, and genotype × environment interaction on yield were highly significant (P < 0.01). KTM-1, KTM-2, KTM-4, KTM-5, and KTM-6 showed higher average grain yield per hectare than the checks (Srikandi Kuning = 8.49 ton ha−1 and BISI-2 = 7.32 ton ha−1) at five different locations. The average harvest age of 11 candidates was less than 100 days. KTM-4 and KTM-5 had production yields that were higher than the average yield of all genotypes in all environments (Yi > 7.78 tons ha−1) and were considered stable on the basis of three stability parameters, i.e., Finlay–Wilkinson, Eberhart–Russell, and additive main effect multiplicative interaction (AMMI). KTM-2 had the highest yield among all tested genotypes (9.33 ton ha−1) and was considered as stable on the basis of AMMI but not on the basis of Finlay–Wilkinson and Eberhart–Russell. KTM-1 performed well only in Pamekasan, whereas KTM-6 performed well only in Sampang. Thus, these two genotypes could be targeted for these specific locations.
