Globally, preferences for fruit trees have fluctuated over time. However, the most desirable attribute of cultivated fruit tree species has not been consistent across all species and locations. Therefore, the purpose of this study was to determine farmers' preferences for fruit tree species and the associated problems they face in four different study sites, categorized by gender and family size. Equal sampling techniques were used in each selected study site, resulting in a total of 120 household heads participating in structured interviews. The data collected was then analyzed using SPSS version 26 software, utilizing the Mann-Whitney U and Kruskal-Wallis tests. Across the study sites, a total of fourteen fruit tree species from ten families were found to be preferred. The preference for fruit trees based on gender showed no significant difference among respondents between kebeles per woreda. However, the preference for fruit trees based on family size showed a significant difference between kebeles per woreda. The number of species preferred for their subsistence value was twice as large as those preferred for commercial reasons. The proportions of these preferred species and the percentage of observed problems with fruit trees varied significantly across the studied sites. Of all the interviewed household heads, 70% in Fenika, 36.6% in Kite, 66.6% in Shesheka, and 50% in Kometa kebeles encountered severe problems during fruit tree planting. The most common problems identified were disease or pest infestation, lack of expert support, land availability, knowledge, and access to seedlings. In order to address these issues, it is important to utilize indigenous knowledge and scientifically tested research approaches to alleviate the factors that influence farmers' preferences.

The productivity of agricultural crops is determined by the choice of varieties, planting material, the optimal time of sowing and planting depending on the climatic conditions of the region, the use of organic and mineral fertilizers, and care methods. Planting material plays an important role in the growth and development of onions and the formation of yield. Onions are very demanding in terms of nutrition, this is due to the length of the growing season, growth rates and poorly developed root system. To obtain high and high-quality onion yields, it is necessary to use fertilizers in an accessible form. Water-soluble complex mineral fertilizers quickly and evenly penetrate deep into the soil. Fertilizers improve the growth and development of plants, regulating nutrition processes, increase the yield and quality of the resulting products. As a result of many years of research, it was found that optimizing the mineral nutrition of onions through the use of fertilizers in active form provides a significant increase in the yield of onions. A comparative assessment of the productivity of onions when grown from sets of different fractions using water-soluble complex mineral fertilizers in the conditions of the Udmurt Republic has been little studied.Materials and methods. The purpose of the research: to improve the technology of cultivating onions depending on the fraction of the set and fertilizing with water-soluble complex mineral fertilizers. In 2020–2021 On onions of the Stuttgarter Riesen variety, a two-factor experiment was carried out to study the effect of fertilizing with Aquarin and Rastvorin fertilizers when using different fractions of sets for planting. The studies were carried out using generally accepted methods.Results and its discussion. In the Udmurt Republic, the optimal for planting Stuttgarten Riesen onions is the medium and large fraction of the set, and the positive effect of water-soluble complex mineral fertilizers Aquarin and Rastvorin on the yield and its structure has been revealed. However, it is more economically profitable to use the fine fraction of sets when growing onions.

This article describes the history of the industrial development of the essential oil industry and the prospects for cultivating such essential oil crops as dill and coriander, including in the territory of Transbaikalia. Data are provided on the volume of essential oil production in Russia in different years. The noted morphobiological features of dill and coriander suggest the possibility of obtaining a high yield of fruits when they are cultivated by agricultural producers in the dry steppe zone of Transbaikalia. For the first time, in the conditions of the dry steppe zone of Transbaikalia, field research was carried out to study the effectiveness of some agricultural practices for cultivating zoned varieties of dill and coriander. The results of three years of research (2021-2023) on the formation of fruit yield of plants of the Umbrella family with a one-year development cycle - dill (Gribovsky, Lesnogorodsky varieties) and coriander (Karibe variety) in the driest soil-climatic zone of Transbaikalia are summarized. It was revealed that the heat supply of the growing season affects the formation of the fruit yield of the studied crops. The highest fruit yield was obtained from the Gribovsky dill variety at an average sowing time, and from the Lesnogorodsky variety when sowing early. At the same time, the Gribovsky variety is superior in yield to the Lesnogorodsky variety. The coriander variety Caribe provided the maximum fruit yield at a late sowing time in all years of research. In general, the soil and climatic conditions of the dry steppe zone of Transbaikalia make it possible to obtain a harvest of aromatic dill and coriander at the level of other regions of Russia, which determines the future development of essential oil crop production in our region.

In different agro-climatic zones of melon growing, an assessment was carried out and two-year results of agro-ecological tests of watermelon varieties of the Kuban and Volgograd selection were obtained. The cultivars of the Federal Research Center of Rice and Bikovskaya cucurbits breeding experimental station, which can be grown and are guaranteed to receive high yields of watermelon in the Central zone of the Krasnodar Territory and the Middle Volga region, are distinguished by yield and quality. Growing varieties of the Kuban selection Nitsa and Yubilyar in the steppe zone of insufficient moisture of the Volgograd Trans-Volga region for two years ensured a high yield of watermelon fruits – 16.0-17.4 t/ha, with a content of dry soluble substances in the fruit pulp of more than 10%. When testing varieties of the Volgograd selection in the Central zone of the Krasnodar Territory, varieties of the late-ripening group Ikar and Rubin showed a stable yield. Under different weather conditions of the growing season, the maximum yield of fruits was obtained. The Volzhanin variety was highly rated for quality with a sugar content of more than 12%, but under extreme weather conditions it may be inferior in yield to the varieties of the Kuban selection. A two-year agro-ecological test of watermelon made it possible to evaluate and identify varieties that are recommended to farmers for a particular growing area.

Quinoa (Chenopodium quinoa Willd.) is a cultivated plant of the Amaranthaceae family of Peruvian origin with high nutritional value. The Krasnodar region of Russia is a region with favorable climatic conditions for growing quinoa. The studies were carried out on the basis of Quinoa Center LLC, located in the Novokubansky district of the Krasnodar Territory. Four quinoa varieties were used as research material: Blanca de Juli, White Peru, Salcedo, the local variety Seva (included in the State Register of the Russian Federation in 2017) served as the standard. Various morphological parameters of plants were assessed and phenological observations were carried out.The results showed statistically significant differences between varieties in plant productivity. The White Peru variety responded positively to the new conditions and was introduced without irrigation. The productivity of the panicle was on average 100 g, for the standard variety Seva - 70 g. In the dynamics of the ontogenetic development cycle of four quinoa varieties, it was established that the optimal sowing time in the conditions of the Krasnodar Territory is May. The tested varieties were also assessed for grain quality. In the conditions of the Krasnodar region they showed good results, thanks to selection for white grain and panicle uniformity. However, not all of them can be adapted, since they need constant watering and for late-ripening varieties autumn rains negatively affect their yield. The local early ripening variety Seva is of interest to Peru. In Peru, the main problem reducing production is low yield caused by frost in the Puno Peru region. The Seva variety reaches phenological phases: the beginning of panicle formation (R6), panicle formation (R7), flowering (R8) and full panicle ripening, physiological maturity (R12) and due to its early ripening it avoids frost. Therefore, the Seva variety can be recommended for sowing in the Puno-Peru region, since it has a gene pool that provides cold resistance but this requires detailed study. In general, to optimize the introduction of quinoa in Russia further research on adaptability in the Krasnodar region is necessary.
藜麦(藜麦野生)是一种栽培植物苋菜科的秘鲁原产地具有很高的营养价值。俄罗斯克拉斯诺达尔地区是一个气候条件有利的地区，适合种植藜麦。这些研究是在位于克拉斯诺达尔地区新库班斯基区的藜麦中心有限责任公司的基础上进行的。四种藜麦品种被用作研究材料:Blanca de Juli, White Peru, Salcedo，当地品种Seva(于2017年列入俄罗斯联邦国家登记册)作为标准。评估了植物的各种形态参数，并进行了物候观察。结果表明，品种间植物生产力差异有统计学意义。秘鲁白品种对新条件反应积极，引进时没有灌溉。穗产量平均为100克，标准品种Seva - 70克。在4个藜麦品种的个体发育周期动态分析中，确定了克拉斯诺达尔地区条件下的最佳播种期为5月。并对试验品种进行了籽粒品质评价。在克拉斯诺达尔地区的条件下，它们表现出良好的结果，这要归功于白粒和穗均匀性的选择。然而，并不是所有的品种都能适应，因为它们需要不断的浇水，而对于晚熟品种来说，秋雨对它们的产量有负面影响。秘鲁对当地的早熟品种Seva很感兴趣。在秘鲁，减产的主要问题是普诺秘鲁地区霜冻造成的低产量。Seva品种达到物候阶段:穗形成开始阶段(R6)、穗形成阶段(R7)、开花阶段(R8)和全穗成熟、生理成熟阶段(R12)，由于早熟，避免霜冻。因此，Seva品种可以推荐在普诺-秘鲁地区播种，因为它有一个提供抗寒性的基因库，但这需要详细的研究。综上所述，为了优化藜麦在俄罗斯的引种，有必要进一步研究藜麦在克拉斯诺达尔地区的适应性。

Relevance and methodology. In order to determine the effect of increasing the proportion of far red light (different ratio of red and far red light) in the total spectrum of polychrome irradiation on the growth rates of sugar beet plants of the Smena hybrid, they were grown for 82 days under LED lighting under controlled climate conditions in a Synergotron digital device of the ISR 2.01 model with a twofold increase in the proportion of far red light compared to control.Results. An increase in the proportion of far red light led to an increase in the specific weight of leaves with a smaller area of leaves in the initial period of plant growth, higher values of the quantum yield of photosynthesis, the rate of electron transport, and a decrease in energy losses mainly to heat. The biometric indicators of plants changed depending on the period of ontogeny. In the initial period, the biomass of the aerial part prevailed, in the subsequent period, the biomass of root crops. In the experimental variant, the accumulation of biomass in the aerial parts of plants in the initial period of the experiment turned out to be less than in the control, and only at the end of the experiment was an excess of the total biomass in the experimental variant by 12.2%. There was an increase in the accumulation of root biomass compared to the control by 38.7%. The predominant part of the aboveground biomass of sugar beet was made up of leaf blades, the proportion of petioles was much less and practically did not depend on the composition of the light. At the end of the growing period, the dry matter content in root crops increased by 2.44% compared to the control, sugar content – by 0.65%. The data obtained can be used in the development of technology for artificial lighting of sugar beets when grown in closed agrobiotechnosystems in order to increase the yield and sugar content of root crops.

Relevance. Potato varieties Eurasia and Onezhskiy were developed as a result of cooperation between the Murmansk State Agricultural Experiment Station – branch of the VIR and the Leningrad Scientific Research Institute of Agriculture "Belogorka" and were included in the State Register of the Russian Federation in 2014 (Onezhsky) and in 2017 (Eurasia). To determine the prospects for cultivation in the Kola North, the varieties were tested in the conditions of the Murmansk region.Materials and methods. The research was carried out on the experimental field of the Murmansk State Agricultural Experiment Station – branch of the VIR in 2018-2020. Potato varieties Eurasia and Onezhskiy were obtained from the Leningrad Research Institute of Agriculture "Belogorka". The plot in the experiment included 4 rows of 15 tubers in each row. The planting pattern is 70x35 cm. Repetition – four times. The location of the plots is systematic with the plots being shifted along tiers. Early maturity was assessed using one test coping on the 70th day after planting. The Elizabeth variety was used as a standard. The results were processed using the method of analysis of variance according to Dospekhov.Results. The research results showed that the Onezhsky variety is distinguished by high starchiness, non-darkening flesh and good taste, is resistant to pathogens: Synchytrium endobioticum (Schilbersky) Percival, Streptomyces scabies (Thaxter), Globodera rostochiensis (Wollenweber) Behrens, relatively resistant to Phytophthora infestans (Mont . De Bary), is weakly affected by Potato virus Y (PVY), Potato leaf roll virus (PLRV). The Onezhsky variety, on average, over three years of research exceeded the standard sample in terms of yield and plant productivity. The Eurasia variety has high starchy content, good taste, culinary type B, is resistant to pathogens: Potato virus Y (PVY), Potato leaf roll virus (PLRV), Globodera rostochiensis (Wollenweber) Behrens, Synchytrium endobioticum (Schilbersky) Percival, moderately susceptible to Phytophthora infestans (Mont. De Bary). The Eurasia variety also exceeded the standard sample in terms of yield and plant productivity. Thus, the Onezhsky and Eurasia potato varieties are recommended for cultivation in the Kola North.

To study the remobilization rate affected by growth regulators in wheat a field experiment was carried out in the south of Iran over 2017-2019 with a split-split plot design and three iterations in completely randomized blocks. The main plots were two irrigation regimes (full irrigation and irrigation interruption at the grain-filling stage), two wheat cultivars (Chamran 2 and Durum Karkheh cv.s) were as sub plots, and four growth regulators (control (no growth regulator), salicylic acid, jasmonic acid, and cytokinin) placed in sub-sub plots. Results revealed the significant impact of the triple interaction on grain yield. The highest grain yield (4803 kg/Ha) was observed for Chamran 2 cv. treated with complete irrigation and salicylic acid. Although grain yield declined by 15.5% in the Karkheh cv. with irrigation interruption at the grain-filling stage and non-administration of growth regulators, treatment with salicylic acid managed to attenuate the adverse impact of drought stress in grain yield. The highest current photosynthesis and its contribution were observed in cultivars treated with complete irrigation. Moreover, irrigation regimen and growth regulators each had significant impacts on proline, catalase enzyme, and stomatal conductance. Overall, results suggested that using salicylic acid in Chamran 2 cv. would be advisable to increase growth and grain yield and reduce decline under stress.

Relevance. Tomato is one of the most beloved and popular vegetables among Primorye residents. But in the monsoon climate, the Far Eastern Primorye has the most intense infectious background in Russia. The yield losses of tomato fruits from alternariosis annually amount to 30% or more. Losses from late blight on the background of epiphytotics in years with wet and cold summers, as observed in 2019, depending on the stability of the variety, can reach from 17 to 100%. Despite the fact that the development and use of biological means of control has recently been a priority, it is still too early to abandon chemical protection measures. High efficiency and versatility of the correctly selected scheme of application of fungicides, short processing time – all this gives a quick and reliable result in protecting tomato crops and reducing the harmfulness of the complex of diseases.Methodology. The research was carried out in 2019-2021 at the Primorsky Vegetable Experimental Station (PVES) – a branch of the Federal Scientific Vegetable Center in the monsoon climate of the coastal zone of Primorsky Krai. We studied the effect of chemical preparations Signum, Orvego and their tank mixture with igum + Orvego on the development of diseases, yield indicators and the structure of the tomato crop varieties Odyssey, and Fitilek. Agrotechnics of cultivation are generally accepted in Primorsky Krai for tomato culture.Results. Testing of chemical fungicides in the conditions of Primorsky Krai showed that the development of alternariasis, starting with the appearance of the first signs of damage in the first half of the growing season, effectively restrains the fungicide Signum, contributing to the preservation of the working leaf surface. It is advisable to use the tank mixture With igum + Orvego starting from the first or second decade of August, when a complex of phytopathogens develops on the leaf surface. The introduction of these two fungicides into the tank mixture leads to an increase in the biological and economic effectiveness of protective measures in the fight against alternariasis and late blight of tomatoes, compared with the standard fungicide Acrobat MC. Joint Signum Processing+Orvego, by reducing the intensity of disease development and the share of the non-commodity part of the crop, has a beneficial effect on the mass of commercial fruit and contributes to a more complete realization of the productive potential of Odyssey and Fitilek varieties.
的相关性。西红柿是滨海边疆区居民最喜爱和最受欢迎的蔬菜之一。但在季风气候下，远东滨海地区具有俄罗斯最强烈的传染病背景。番茄交替病每年造成番茄果实产量损失达30%以上。正如2019年观察到的那样，在夏季潮湿和寒冷的年份，晚枯萎病造成的表观植物损失可达17%至100%，具体取决于品种的稳定性。尽管发展和使用生物防治手段最近已成为优先事项，但放弃化学防护措施仍为时过早。选择正确的杀菌剂施用方案，效率高、用途广，处理时间短，对保护番茄作物和减少复合病害的危害具有快速、可靠的效果。这项研究于2019年至2021年在滨海边疆区蔬菜实验站(PVES)进行，这是联邦蔬菜科学中心在滨海边疆区沿海季风气候下的一个分支机构。研究了化学制剂Signum、Orvego及其与igum + Orvego罐内混合剂对番茄品种奥德赛(Odyssey)和菲蒂莱克(Fitilek)病害发展、产量指标和结构的影响。在滨海边疆区，种植番茄的农业技术被普遍接受。在滨海边疆区的条件下进行的化学杀菌剂测试表明，在生长季节的前半段出现第一个损害迹象时，交替病的发展就开始了，有效地抑制了杀菌剂Signum的使用，有助于保存工作叶片表面。宜在8月上旬或下旬开始使用igum + Orvego混合液，此时叶片表面出现植物病原体复合体。与标准杀菌剂Acrobat MC. Joint Signum Processing+Orvego相比，将这两种杀菌剂加入罐混合物中，通过降低疾病发展的强度和作物非商品部分的份额，提高了防治番茄交替病和晚疫病的保护措施的生物和经济效益。对商品水果的质量有有益的影响，并有助于更全面地实现奥德赛和菲蒂莱克品种的生产潜力。
