Abstract:
Weed control is an important technological operation in the cultivation of all types of agricultural crops, especially row crops, vegetables and grains. Since weeds have an increased ability to grow and develop at low temperatures in early agrotechnical terms. Then the fight against them in the preparation of the soil before sowing is a necessary condition for maintaining moisture and obtaining consistently high crop yields. When carrying out agrotechnical measures aimed at weed control, cultivators for continuous tillage are used, which are used for tillage before sowing and when caring for fallows. But when cultivating, the cut weeds overhang on the rack of the working body of the cultivator. This violates the agrotechnical requirements for tillage and reduces the productivity of the unit during cultivation. To eliminate these shortcomings, a device has been developed that provides protection for the cultivator leg rack from overhanging cut weeds during cultivation. The created working body can be installed on the existing frame structure of the steam cultivator without its modification. The operation of a steam cultivator with an improved working body allows you to increase the productivity of work on cultivation by 15%.

Abstract:
Abstract The aim of the study was to determine the influence of cover crops biomass, mixed with the soil on different dates and with the use of different tools in field conditions. The cover crop biomass had a beneficial influence on the total porosity of the 0-20 cm layer of the soil after winter. The highest porosity was achievedwith cover crops of buckwheat, phacelia and mustard, the lowest with rye. During the vegetation period the highest porosity of soil was observed in the ridges. Among the remaining non-ploughing cultivations, pre-winter use of stubble cultivator proved to have a beneficial influence on the soil porosity, providing results comparable to those achieved in conventional tillage. The differential porosity of the soil was modified not only by the catch crops and the cultivation methods applied, but also by the sample collection dates, and it did change during the vegetation period. The highest content of macropores after winter was observed for the phacelia cover crop, and the lowest in the case of cultivation without any cover crops. Pre-winter tillage with the use of a stubble cultivator increased the amount of macropores in soil in spring, and caused the biggest participation of mesopores as compared with other non-ploughing cultivation treatments of the soil. The smallest amount of mesopores was found in the ridges.

Abstract:
The saving technologies of agricultural crops cultivation was discussed. The main ways to achieve resource savings were reflected in the article. It was revealed, that one of the main conditions for successful implementation of resource-saving technologies is the use of high-performance agricultural machines. We proposed a ridge cultivation technology for row crops and mechanization means for its implementation, in particular, ridged seed planter and row-crop cultivator, equipped with combined working parts. The ridged seed planter performs the following operations for one pass: sowing cultivation, sowing, ridging the soil over the seeded seeds and packing. An application of row-crop cultivator allows to perform care for row crops with a high quality, with the complete destruction of weeds in the protection zones of rows without using environmentally harmful herbicides. When using a ridge cultivation method, several activities carried out in a single pass of a machine, and it reduces the energy and resource consumption, maintains soil fertility and improves the environment.

Abstract:
Protected cultivation is an important initiative for cultivating the high value horticultural crops especially during the off-season which enables the farming communities to generate higher revenues in the limited area. In this context, a study has been undertaken to find out the viability of the protected cultivation structures for the cultivation of horticulture crops of capsicum and tomato in the regions of Kalyana-Karnataka. The research study was conducted in the district of Koppal and Ballari in regions of Kalyana-Karnataka based on the existence of highest number of protected structures. The study was based on primary data through personal interview method of the farmers who have adopted protected cultivation technology. A sample of 60 farmers were drawn as respondents from each district based on their size and composition of the structures and also on the basis of crops grown under protected condition. The data collected from the farmers with respect to the cost and return of capsicum and tomato under protected cultivation were analysed using cost and returns analysis techniques. The results reported that, the net returns of capsicum and tomato crops in protected cultivation were Rs. 2,92,768 and Rs. 2,28,289 respectively in an area of of 1008 sqm and the B:C ratios of capsicum and tomato crops were reported as 1:3.40 and 1:2.89 respectively. Thus, the protected cultivation structures in the regions of Kalyana-Karnataka for the cultivation of tomato and capsicum crops were found as economically viable unit. Hence, effort may be needed from the farmers of this region with further government support for increasing the adoption of protected cultivation structures in the cultivation of high value horticultural crops like tomato and capsicum.

Abstract:
The purpose of the studies was to establish the quantitative composition of bacteria Bacillus spp. and Pseudomonas spp. and their antagonistic effect towards soil-borne fungi after the cultivation of oats, spring vetch and tansy phacelia as intercrop cover plants. The total population of bacteria in 1 g dry weight of the soil from the experimental combination where mulch of oats was used was larger than in the combination with spring vetch or tansy phacelia. Totally, approximately three times as much Bacillus spp. was obtained from soil samples as compared to Pseudomonas spp. Tests showed that the most isolates of antagonistic bacteria out of the enumerated genera occurred in the soil after oats cultivation, and the least in the soil after the cultivation of tansy phacelia. Antagonistic Bacillus spp. and Pseudomonas spp. inhibited the growth and development of Fusarium oxysporum, Haematonectria haematococca and Thanatephorus cucumeris in the most effective way. The greatest total antagonistic effect of Bacillus spp. and Pseudomonas spp. towards Altenaria alternata, F. culmorum, F. oxysporum, H. haematococca, P. irregulare and T. cucumeris was found out after managing the mulch of oats. The smallest total antagonistic effect of bacteria was observed after managing the mulch of tansy phacelia.

Abstract:
The Precision Cultural System (PCS) developed by the Louisiana Agricultural Experiment Station allows simple and precise cultivation of vegetable crops; however, speed of the cultivators in small vegetable crops has been limited. The standard PCS sweep cultivator was limited to about 1.6–2.4 km·h–1 in small crops because it would throw soil over the crop plants at higher speed. The standard PCS rotary tiller cultivator could operate at 3.2–4.8 km·h–1 in small crops but could not be operated faster in larger crops, due to its tendency to “walk” out of the soil at higher speeds. The standard PCS sweep cultivator was modified by replacing the sweeps between the twin drills with two pairs of straight finger-wheel (“rolling cultivator”) spiders non-angled and in tandem. The finger-wheel gangs on the bed sides were also inactivated by raising them above the soil. The resulting PCS cultivator was successfully operated in very small crop plants (≤25 mm high) at speeds of 8–10 km·h–1 with no crop damage. The cultivator could then be easily refitted for standard sweep cultivation on subsequent passes. No reductions in weed control or yield of mustard, kale, turnip, or spinach were noted when using the high-speed system.

Abstract:
In order to examine the influence of inter-row cultivation on the soybean yield, a trial was set up in the Agricultural School in Backa Topola from 2015 to 2017. Three soybean varieties were selected at the Institute of Field and Vegetable Crops in Novi Sad. Galina, Sava and Rubin were used. The trials included the different number of inter-row cultivations: control - without inter-row cultivation, one inter-row cultivation, two and three inter-row cultivations of soybean crops. Obtained results showed that an average yield of soybean increased with an increase in the number of inter-row cultivations during the soybean vegetation period. With one inter-row cultivation, the yield increase was 5.33%, with two inter-row cultivations - 7.10% and with three cultivations - 7.33%. In the years with a lower precipitation, the influence of intra-row cultivation was much more effective. In 2017, the increase ranged from 10.33% to 13.62%, and in 2016 from 3.09% to 4.27%. Yield was increased due to reduced evapotranspiration of soil moisture as well as prevention of descending of water into deeper layers. During summer, this allowed better water conservation in the soil for critical periods, and also increased the activity of microorganisms as well as more intensive mineralization of organic matter, which ultimately influenced the yield.

Energy crops offer ecological advantages over fossil fuels by contributing to the reduction of greenhouse gases and acidifying emissions. However, there could be ecological shortcomings related to the intensity of agricultural production. There is a risk of polluting water and air, losing soil quality, enhancing erosion and reducing biodiversity. In the scope of the project Future Crops for Food, Feed, Fiber and Fuel (4F Crops), supported by the European Union, an environmental impact assessment study was developed and applied to the cultivation of potential energy crops in the Mediterranean Europe. The categories selected were: use of water and mineral resources, soil quality and erosion, emission of minerals and pesticides to soil and water, waste generation and utilization, landscape and biodiversity. Results suggest that annual cropping systems have a more negative impact on the environment than lignocellulosic and woody species, namely regarding erodibility and biodiversity. Annual systems and woody crops are also more damaging to soil quality than herbaceous perennials. However, differences among crop types are not as evident in the remaining indicators. Impact reduction strategies are limited to crop management options, but, site specific factors should be accurately assessed to evaluate the adequacy between crop and location.

Abstract:
Field trials were conducted in 2010/11, 2012 and 2013 at the Royal Agricultural University’s Soil Association certified organic Harnhill Manor Farm, Gloucestershire, UK (NGR SP 075 006), to investigate suitable cultivation techniques and legume cover crops for winter and spring wheat production. Cultivation treatments included conventional tillage (CT), low residue non-inversion tillage (LRNiT) and high residue non-inversion tillage (HRNiT) as main plots while undersowing white clover (WC), black medic (BM) or no undersowing (Nus) as subplots. Wheat establishment, growth, grain yield and weeds infestation were assessed to determine the feasibility of these husbandry techniques. For winter wheat in 2010/11, LRNiT seems to be an acceptable alternative for CT. However, for spring wheat in 2012 and 2013, CT seems to be more reliable management option. The performance of undersown legumes was highly weather reliant and inconsistent in the seasons studied. Plant establishment and the succeeding yield parameters were positively related to grain yield. CT had significantly higher plant establishment than LRNiT or HRNiT in each season. For winter wheat, the competition and compensation on shoot density among CT and LRNiT did potentially outweighed cultivation-induced effects on plant establishment. This condition resulted in statistically equivalent crop growth and yields with LRNiT to that of CT. In contrast, for spring wheat in 2012 and 2013, CT that had significantly higher plant establishment also resulted in better crop growth and greater grain yields than other cultivation treatments. In all seasons, HRNiT had significantly lower plant establishment and also reduced grain yields, compared with LRNiT or CT. More soil cultivation also significantly reduced total weeds than less tilled soil such as HRNiT. On the basis of weed species, significantly higher broadleaf weeds were present under CT and significantly higher grass weeds were present under HRNiT. Out of three investigated years, legume cover crops effects were clearly observed only in 2012 with spring wheat. More vigorous growth of WC showed a significantly inverse relationship with broadleaf weeds and total weeds, compared with slow growing BM. This situation, resulted in non-significant yield components or grain yield reduction, compared with non-undersown spring wheat. In this context, white clover seems to be more suitable legume cover crop than black medic.

Abstract:
Conditions are predicted to become more favorable for protein-rich crops in Northern Europe, which bring opportunities for cultivation of protein-rich crops in Sweden. This study assessed the current suitability for cultivation of protein-rich crops in Sweden based on biophysical conditions. This study defined suitability indicators with suitability conditions for each crop regarding (i) soil texture, (ii) soil pH value, (iii) vegetation period length, (iv) and soil temperatures were created, and overlayed to create suitable areas for protein-rich crops. Suitable areas and distributions were found for: common bean, faba bean, field pea, lentil, narrow-leafed lupin, quinoa, and soybean. A present and future risk analysis with wet and dry periods was carried out to find suitable areas for the crops under the risk of wet and dry periods. The study found that Sweden have the possibility to cultivate protein-rich crops to a greater extent which is shown by the distribution of suitable areas for protein-rich crop. Quinoa was found suitable to be cultivated in nearly all arable land in Sweden. In the future, there is an increase in suitable areas for protein-rich crops that are not exposed to drought. A decrease was seen in suitable areas for protein-rich crops that are not exposed to flooding.

Abstract:
Bioenergy is expected to play an increasingly significant role in the global energy budget. In addition to the use of liquid energy forms such as ethanol and biodiesel, electricity generation using processed energy crops as a partial or full coal alternative is expected to increase, requiring large-scale conversions of land for the cultivation of bioenergy feedstocks such as cane, grasses, or short rotation coppice. With land-use change identified as a major contributor to changes in the emission of biogenic volatile organic compounds (BVOCs), many of which are known contributors to the pollutants ozone (O3) and fine particulate matter (PM2.5), careful review of crop emission profiles and local atmospheric chemistry will be necessary to mitigate any unintended air-quality consequences. In this work, the atmospheric consequences of bioenergy crop replacement are examined using both the high-resolution regional chemical transport model WRF/Chem (Weather Research and Forecasting with Chemistry) and the global climate model CESM (Community Earth System Model). Regional sensitivities to several representative crop types are analyzed, and the impacts of each crop on air quality and climate are compared. Overall, the high emitting crops (eucalyptus and giant reed) were found to produce climate and human health costs totaling up to 40% of the value of CO2 emissions prevented, while the related costs of the lowest-emitting crop (switchgrass) were negligible.

Abstract:
Conservation tillage tobacco production has gained little producer acceptance since introduction in the late 1960's. Yield reductions, tobacco quality issues, unacceptable weed control, and inadequate planting equipment limited practice adoption and substantiated the need for continued research. The recent developments of a Subsurface Tiller-TransplanterTM and the herbicide SpartanTM renewed producer interest in conservation tillage and led to an investigation with both flue-cured and Virginia dark-fired tobacco. Flue-cured tobacco was transplanted into rye mulch on bedded rows and subsequently cultivated at various timings. Conservation tillage significantly reduced soil erosion approximately 92 percent and tobacco yield approximately 23 percent when row cultivation was not applied. Row cultivation significantly increased tobacco yield without increasing soil erosion. The yield of conservation tillage tobacco receiving a minimum of two cultivations was similar to conventional tobacco. The second study evaluated wheat, rye, crimson clover, and mixtures of crimson clover with either wheat or rye as cover crop mulches for conservation tillage production of Virginia dark-fired tobacco. Conservation tillage, regardless of cover crop, reduced dark-fired tobacco yields approximately 779 and 488 pounds per acre in 1996 and 1997, respectively. The removal of cover crop residue for hay did not lower tobacco yield compared to leaving residue on the soil surface. Row cultivation increased conservation tillage tobacco yield approximately 247 pounds in 1997 regardless of cover crop. The nitrogen contribution of crimson clover was minimal in both years of the study and did not affect tobacco performance.

This chapter summarizes information on a selected range of common hydroponic crops to give basic procedures for each and an outline of the systems of production. These crops include tomato, capsicum or sweet bell pepper, cucumber, lettuce and other salad greens, strawberry and rose. Information is given on their hydroponic production systems and environment, propagation, plant density, pruning, pollination, fruit growth, crop nutrition, pests, diseases, disorders, harvesting and postharvest handling.

Abstract:
This paper aims to determine the economic efficiency that each of the three main oil crops can have, namely the sunflower, soybean and rapeseed in Romania. Starting from the cultivation technologies of these plants it can be determined the main expenses for the cultivation of one hectare. With the help of statistical data on the price of recovery and the average production per hectare, it can be determined the incomes obtained by cultivating each crop taken into consideration, thus, at the end of this paper, it can determined the economic efficiency of cultivating one hectare with one of the three crops studied. These calculations will be performed for two levels of production; thus, two scenarios will be estimated for each crop chosen.

Full text
Abstract:
One explanation for the increasing number of hectares with coca cultivation is that eradication strategies displace coca crops but fail to completely clear affected areas. In the drug policy literature, that dynamic shifting is commonly known as the balloon effect. This study integrates georeferenced agricultural data through spatially explicit econometric models to test the hypothesis that forced eradication displace coca crops. Using annual data for 1,116 contiguous municipalities in Colombia between 2001 and 2015, we estimate a spatial Durbin model with municipal and time fixed effects. Our results suggest that, on average, aerial fumigation in a municipality diffuses the benefits of this crime control strategy to neighboring municipalities.

Abstract:
Using treated wastewater (TWW) for crop irrigation represents an important opportunity for ensuring adequate food production in light of growing freshwater scarcity worldwide. However, the environmentally sustainable approach of using TWW for irrigation can lead to contamination of produce with fecal pathogens that may remain in treated water. The overall goal of this research was to evaluate the correlation between the presence of fecal indicator bacteria (FIB) and that of a suite of human pathogens in TWW, the irrigated soil, and crops. Field experiments were conducted to compare secondary and tertiary TWW with dechlorinated tap water for irrigation of tomatoes, a typical commercial crop, in Israel, a semi-arid country. Human pathogens including bacteria (Salmonella), protozoa (Cryptosporidiumand Giardia), and viruses (Adenovirus [AV Types A, B, C & 40/41] and Enterovirus [EV71 subtypes]) were monitored in two field trials using a combination of microscopic, cultivation-based, and molecular (qPCR) techniques. Results from the field trials indicate that microbial contamination on the surface of tomatoes did not appear to be associated with the source of irrigated waters; FIB contamination was not statistically different on tomatoes irrigated with TWW as compared to tomatoes irrigated with potable water. In fact, Indicator bacteria testing did not predict the presence of pathogens in any of the matrices tested. High concentrations of FIB were detected in water and on tomato surfaces from all irrigation treatment schemes, while pathogen contamination on tomato surfaces (Cryptosporidiumand Salmonella) was only detected on crops irrigated with TWW. These results suggest that regular monitoring for pathogens should take place to accurately detect presence of harmful microorganisms that could threaten consumer safety. A notable result from our study is that the large numbers of FIB in the water did not appear to lead to FIB accumulation in the soil. With the exception of two samples, E. coli that was present at 10³ to 10⁴ cells/100 mL in the water, was not detected in the soil. Other bacterial targets associated with the enteric environment (e. g., Proteusspp.) as well as protozoal pathogens were detected in the TWW, but not in the soil. These findings suggest that significant microbial transfer to the soil from TWW did not occur in this study. The pattern of FIB contamination on the surfaces of tomatoes was the same for all treatment types, and showed a temporal effect with more contamination detected as the duration of the field trial increased. An important observation revealed that water quality dramatically deteriorated between the time of its release from the wastewater treatment plant and the time it was utilized for irrigation, highlighting the importance of performing water quality testing throughout the growing season at the cultivation site.

Abstract:
Soilless crop production in protected cultivation requires optimization of many environmental and plant variables. Variables of the root zone (rhizosphere) have always been difficult to characterize but have been studied extensively. In soilless production the opportunity exists to optimize these variables in relation to crop production. The project objectives were to model the relationship between biomass production and the rhizosphere variables: temperature, dissolved oxygen concentration and water availability by characterizing potential growth and how this translates to actual growth. As part of this we sought to improve of our understanding of root growth and rhizosphere processes by generating data on the effect of rhizosphere water status, temperature and dissolved oxygen on root growth, modeling potential and actual growth and by developing and calibrating models for various physical and chemical properties in soilless production systems. In particular we sought to use calorimetry to identify potential growth of the plants in relation to these rhizosphere variables. While we did experimental work on various crops, our main model system for the mathematical modeling work was greenhouse cut-flower rose production in soil-less cultivation. In support of this, our objective was the development of a Rose crop model. Specific to this project we sought to create submodels for the rhizosphere processes, integrate these into the rose crop simulation model which we had begun developing prior to the start of this project. We also sought to verify and validate any such models and where feasible create tools that growers could be used for production management. We made significant progress with regard to the use of microcalorimetry. At both locations (Israel and US) we demonstrated that specific growth rate for root and flower stem biomass production were sensitive to dissolved oxygen. Our work also identified that it is possible to identify optimal potential growth scenarios and that for greenhouse-grown rose the optimal root zone temperature for potential growth is around 17 C (substantially lower than is common in commercial greenhouses) while flower production growth potential was indifferent to a range as wide as 17-26C in the root zone. We had several set-backs that highlighted to us the fact that work needs to be done to identify when microcalorimetric research relates to instantaneous plant responses to the environment and when it relates to plant acclimation. One outcome of this research has been our determination that irrigation technology in soilless production systems needs to explicitly include optimization of oxygen in the root zone. Simply structuring the root zone to be “well aerated” is not the most optimal approach, but rather a minimum level. Our future work will focus on implementing direct control over dissolved oxygen in the root zone of soilless production systems.

Abstract:
Review question / Objective: The objective of this review is to analyze the effect of zero-tillage and organic mulching (with emphasis on rice-straw) on several Key Performance Indicators (KPIs) related to productivity, resources-use efficiency, and soil health, as well as, C footprint, and weed control for growing potatoes in rice-based systems in Asia. Can zero-tillage and organic mulching increase agronomic gain in potatoes crop in Asia? Rationale: Potato cultivation under zero-tillage and mulching (PZTM) between rice or rice-other crops projects a sustainable intensification of rice-based systems reducing mechanical soil disturbance with a concomitant increase of soil organic matter. However, collection, analysis, and synthesis of experiences in Asia, where this technology was mainly reported, is missing in the scientific literature. This effort, presented in this review, is crucial as a starting point for establishing if PTZM experiences have improved indicators related to productivity, resource use efficiency and soil health, and C footprint and weed management to achieve Agronomic Gain.

Abstract:
This position paper explores the importance of promoting investment in alternative agricultural products in Kenya to enhance food security and foster a resilient food system. The paper analyzes the current state of maize production and consumption in Kenya, compares it to neighboring countries, and delves into the challenges and inefficiencies of maize cultivation and transforming household diets. By examining comparable crops within Kenya and East Africa, it highlights potential solutions to the issues plaguing maize production and consumption. The dietary diversity of Kenyan households and its changes over time are investigated to identify underlying causes, and the unchanging demand for calorie-dense foods like maize is scrutinized. The paper proposes a paradigm shift towards a diversified food system and assesses past structural and behavioral interventions, identifying gaps that require attention.

Abstract:
Despite notable progress in reducing global poverty and hunger in recent decades, about one out of nine people in the world suffers from hunger and malnutrition. Stakeholders charged with making decisions pertaining to agricultural production, development priorities, and policies at a region-to-country scale require quantitative and up-to-date information on the types of crops being cultivated, the acreage under cultivation, and crop yields. However, many low- and middle-income countries lack the infrastructure and resources for frequent and extensive agricultural field surveys to obtain this information. Technology supports a change of paradigm. Traditional methods of obtaining agricultural information through field surveys are increasingly being augmented by images of the Earth acquired through sensors placed on satellites. The continued improvement in the resolution of satellite images, the establishment of open-access infrastructure for processing of the images, and the recent revolutionary progress in artificial intelligence make it feasible to obtain the information at low cost and in near-to-real time. In this brief, we discuss the use of satellite images to provide information about agricultural production in low-income countries, and we comment on research challenges and opportunities. We highlight the near-term potential of the methodology in the context of Rwanda, a country in sub-Saharan Africa whose government has recognized early the value of information technology in its strategic planning for food security and sustainability.

Abstract:
1. Abstract: Over the past 25 years, vine cacti of the genera Hylocereus and Selenicereus have been introduced into Israel and southern California as new exotic fruit crops. The importance of these crops lies in their high water use efficiency and horticultural potential as exotic fruit crops. Our collaboration focused on the cytological, molecular and evolutionary aspects of vine cacti polyploidization to confront the agricultural challenge of genetic improvement, ultimately to improve success of vine cacti as commercial fruit crop plants. More specifically, we worked on the: 1- Identification of the putative ancestor(s) of the tetraploid H. megalanthus; 2- Determination of the number of origins of H. megalanthus (single vs. multiple origins of polyploidy); 3- Cytogenetic analysis of BC1 and F1 hybrids; 4- Determination of important agricultural traits and the selection of superior hybrids for cultivation. The plant material used in this study comprised interspecific Hylocereus F1 and first backcross (BC1) hybrids, nine Hylocereus species (58 genotypes), nine Selenicereus species (14 genotypes), and four Epiphyllum genotypes. Two BC1 hexaploids (BC-023 and BC-031) were obtained, a high ploidy level that can be explained only by a fertilization event between one unreduced female gamete from the triploid hybrid and a balanced gamete from the pollen donor, the diploid H. monacanthus. These findings are scientific evidence that support the possibility that “hybridization followed by chromosome doubling” could also occur in nature. Cytomixis, the migration of chromatin between adjacent cells through connecting cytoplasmatic channels, was observed in vine cacti hybrids and may thus imply selective DNA elimination in response to the allopolyploidization process. Evidence from plastid and nrDNA internal transcribed spacers (ITS) sequences support the placement of H. megalanthus within a monophyletic Hylocereus group. Furthermore, both plastid and ITS datasets are most consistent with a conclusion that this tetraploid species is an autopolyploid, despite observations that the species appears to be morphologically intermediate between Hylocereus and Selenicereus. Although the possibility of very narrow allopolyploidly (i.e., derivation from parents that are barely diverged from each other such as closely related species in the same genus) cannot be ruled out entirely based on our data (in part due to the unavailability of Hylocereus species considered to be morphologically the closest relatives of H. megalanthus), the possibility of H. megalanthus representing an intergeneric cross (i.e., Hylocereus × Selenicereus) seems extremely unlikely. Interestingly, the process of homogenization of ITS sequences (concerted evolution) is either incomplete or lacking in both Hylocereus and Selenicereus, and the inclusion of several artificial hybrids in the molecular study revealed the potential for biparental plastid inheritance in Hylocereus. The most important agricultural implication of this research project was the information collected for F1 and BC1 hybrids. Specifically, this project concluded with the selection of four superior hybrids in terms of fruit quality and potential yields under extreme high temperatures. These selected hybrids are self-compatible, avoiding the need for hand cross pollination to set fruits, thus reducing manpower costs. We recently offered these hybrids to growers in Israel for prioritized rapid evaluation and characterization.
