We observed the production of oil crops in the Omsk region in 2016–2020. There are presented data on dynamics of sowing areas under oil crops (sunflower, soybean, oil flax, spring rapeseed, false flax, etc.). Production of oil crops is economically profitable due to sharp rise in sale prices of seeds and decrease in prime cost as a result of lowering of expenses for production. A level of profitability during a research period varied hard depending on expenses for chemicals. The most economically resulting was 2020, yields of oil flax and spring rapeseed was the highest. We studied impact of climatic conditions on yield of oil crops, namely precipitation amount in a period flowering–maturing. Increased interest to oil flax, rapeseed and soybean is conditioned with high economic efficiency of production, good adaptability to the climate of the Western Siberia, high yield and oil content, creating of favorable background for the further crops in rotation. Growth of oil crops production in the Omsk region can be reached both by intensive and extensive components of production. Intensive direction is realized by a range of factors including formation of varietal structure of crops, implementation of an intensive technology including all elements of oil crops cultivation. An extensive way proposes expansion of sowing areas involving fallow lands into sowing structure and northward expansion of early maturing crops cultivation, such as spring turnip rape, false flax and mustard.

Seed Growing

In modern world plant growing soybeans are among the most important protein-oil crops and continue to gain popularity among Russian farmers. The total area under soybean in season 17/18 increased to 2.64 million hectares (+ 18% against season 16/17), with an increase of 21% in the European part of Russia, and 1.64 million tons of oilseeds were harvested. To obtain a high yield with good seed quality, it is very important to create very early, highly productive, ecologically adapted varieties for specific soil and climatic conditions. In the conditions of the Institute of Seed Growing and Agrotechnology - the branch of the FBBUU FNAC VIM in 2013-2017. in breeding nurseries an analysis of the variability of quantitative soybean characteristics was carried out. It has been established that such a feature as the duration of the growing season is characterized by weak variability (6.1%). The average variable characteristics include the number of productive nodes on the plant, the mass of seeds from 1 plant and the mass of 1000 seeds. The widest range of variability (27.3-41.8%) is observed in terms of: plant height, number of branches and beans on the plant, seed yield. In our studies, the lowest coefficient of variation (Cv) was found in the George variety - 24.8%. Studies have shown that the yield of seed varieties of varieties over the years ranged from 0.79 to 3.04 t / ha. The evaluation of the soybean breeding material for productivity in different years of research in meteorological conditions showed that the most productive and stable, irrespective of weather conditions, are H 24/11 and H 2/14 varieties with a vegetation period of 102 days.

Search and introduction of new potato varieties that can be recommended for cultivation in soil and climatic conditions of the Komi Republic are especially important against the background of the average yield in the region of 12.1 t/ha, that is 6.7 t/ha lower than the average in Russia. In 2019-2020 on the basis of the A. V. Zhuravsky Institute of Agrobiotechnology of the Federal Research Center of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences, there were tested potato varieties of the early maturing group – Armada, Meteor, Gulliver, Taifun and Krepysh (standard) and the mid-season group – Varyag, Vympel, Krasa Meshchery, Kumach, Fritella, Vychegodskii and Zyryanets (standard). From the early maturing group, the varieties Armada and Gulliver have been selected as giving a consistently high yield, which exceeded the standard by 6.8-7.1 t/ha on average for two years. Among mid-season varieties no one reliably exceeded the standard variety Zyryanets in terms of yield productivity. The highest yield and marketability was noted for the Fritella variety – 30.5 t/ha and 97 %. All the varieties under study, except for Vychegodskii, showed an average resistance of the tops to late blight damage. Moderate early blight damage of the tops (up to 20 % of the leaf surface) was noted in three varieties – Meteor, Taifun and Vychegodski. The following varieties showed high resistance to common scab - Vympel (no damage), Zyryanets (few lesions) and Gulliver (up to 10 % of tuber surface damage). In all studied varieties the potato tubers were not affected by late blight during both years of research. For cultivation, the agricultural producers of the Komi Republic should use the varieties Armada (29.7 t/ha), Gulliver (28.1 t/ha), Vympel (29.2 t/ha), Fritella (30.5 t/ha), which have good resistance to phytopathogens and high quality of tubers.

Relevance. In Uzbekistan, especially in the south of the republic, in recent years, early ripe varieties of onion Sumbula, Ravnak, Bakhora have become widespread. However, the technology of seed production of early maturing varieties has not been developed. In this regard, several studies were carried out to identify the optimal time for planting the mother plants of the early maturing onion variety Sumbula by using the favorable climatic conditions of southern Uzbekistan.Material and methodology. The material for the research was the early ripe onion variety Sumbula, bred by the Research Institute of Vegetable and Melon Crops and Potatoes. The studies were carried out according to the Methodological guidelines for the ecological testing of vegetable crops in the open field etc. The dates of seed planting were studied.Results. Studies have shown that the highest seed yield (0.97 t/ha) was obtained in the early autumn planting of mother plants on September 1. It was 20% more than in the control variant – September 15. At later planting dates, the seed yield decreases sharply.When mother plants were planted on October 30, the seed yield was only 0,46 t/ha, or 59.7% of the control.The yield of onion seeds increases, mainly due to the more powerful development of plants during early autumn planting – the formation of large leaves, inflorescences, and additional arrows. The more large and powerful leaves, the more plants have the ability to synthesize plastic substances in the process of photosynthesis and accumulate a high yield.

This study analyses farmers’ adoption of improved rice technology, taking into account farmers’ risk preferences; the unobserved spatial heterogeneity associated with farmers’ risk preferences; farmers’ household and farm characteristics; farm locations, farmers’ access to information, and their perceptions on the rice improved varieties (i.e., high yield varieties, HYV). The study used data obtained from field experiments and a survey conducted in 2016 in Nigeria. An instrumental-variable probit model was estimated to account for potential endogenous farmers’ risk preference in the adoption decision model. Results show that risk averse (risk avoidant) farmers are less likely to adopt HYV, with the spatial lags of farmers’ risk attitudes found to be a good instrument for spatially unobserved variables (e.g., environmental and climatic factors). We conclude that studies supporting policy action aiming at the diffusion of improved rice varieties need to collect information, if possible, on farmers’ risk attitudes, local environmental and climatic conditions (e.g., climatic, topographic, soil quality, pest incidence) in order to ease the design and evaluation of policy actions on the adoption of improved agricultural technology.

Большое значение в увеличении продуктивности картофеля имеет внедрение в производство перспективных высокоурожайных сортов и гибридов, приспособленных к местным природно-климатическим условиям возделывания, от чего зависят эффективность отрасли и себестоимость продукции. Цель работы – изучить влияние климатических условий на продуктивность и качественные показатели сортов и гибридов картофеля, а также использование ими благоприятных почвенно-климатических условий высокогорья Республики Дагестан, для размножения и внедрения в производство новых перспективных, высокоурожайных, приспособленных к условиям среды выращивания сортов картофеля с комплексом хозяйственно-ценных признаков. Объектом изучения послужили сорта картофеля раннего, среднераннего и среднего сроков созревания российской, белорусской и иностранной селекции. Полевые опыты закладывали в 2014–2017 годах на высоте 2000–2200 м, на землях горного опорного пункта «Курахский» Курахского района и на равнинной провинции (Прикаспийской низменности) на территории дачного массива «Наука» Махачкалинского района Республики Дагестан. Схема посадки – 70×30 см, повторность – четырехкратная. Технология выращивания картофеля – гребневая. При проведении полевых опытов использовали общепринятые методики. Практически все сорта картофеля, выращенные на равнинной провинции, сформировали высокий урожай в первый год и при дальнейшем размножении в результате развития вирусных болезней резко снизили свои продуктивные качества. Наиболее высокая урожайность в среднем за три года отмечена у сортов Жуковский ранний (20,8 т/га), Импала (20,5 т/га), Невский (17,8 т/га), Предгорный (16,9 т/га) и Удача (16,3 т/га). В свою очередь, горная провинция Дагестана характеризовалась благоприятными почвенно-климатическими условиями для возделывания как продовольственного картофеля, так и для организации первичного семеноводства на безвирусной основе и размножения перспективных сортов этой культуры. В среднем за годы исследований в горной провинции по урожайности выделились сорта Сильвана (37,4 т/га), Удача (37,6 т/га), Рокко (33,3 т/га), Импала (31,7 т/га), Жуковский ранний (29,0 т/га), Предгорный (27,7 т/га) и Примобелла (27,7 т/га), а также гибриды № 12.40/17 (43,1 т/га) и № 13.61/61 (38,8 т/га). The introduction of promising high-yielding varieties and hybrids adapted to the local natural and climatic conditions of cultivation is of great importance in increasing the productivity of potatoes, which determines the efficiency of the industry and the cost of production. The aim of the work is to study the influence of climatic conditions on the productivity and quality indicators of potato varieties and hybrids, as well as their use of favorable soil and climatic conditions in the highlands of the Republic of Dagestan, for breeding and introducing into production new promising, high-yielding, adapted to the growing environment of potato varieties with a complex of economically valuable characteristics. The object of the study was potato varieties of early, mid-early and medium maturation periods of Russian, Belarusian and foreign selection. Field experiments were conducted in 2014–2017 at an altitude of 2000–2200 m, on the lands of the mountain stronghold Kurakhsky of the Kukhar district and on the plain province (the Caspian lowland) on the territory of the suburban area Nauka of the Makhachkala district of the Republic of Dagestan. The landing scheme is 70×30 cm, the repeatability is four times. The technology of growing potatoes is combed. When conducting field experiments, generally accepted methods were used. Almost all potato varieties grown in the lowland province formed a high yield in the first year and, with further propagation, as a result of the development of viral diseases, sharply reduced their productive qualities. The highest yield on average for three years was observed in the varieties Zhukovskiy ranniy (20.8 t/ha), Impala (20.5 t/ha), Nevsky (17.8 t/ha), Predgornyy (16.9 t/ha) and Udacha (16.3 t/ha). In turn, the mountain province of Dagestan was characterized by favorable soil and climatic conditions for the cultivation of both food potatoes, and for the organization of primary seed production on a virus-free basis and the reproduction of promising varieties of this crop. On average, over the years of research in the mountain province, the varieties Silvana (37.4 t/ha), Udacha (37.6 t/ha), Rocco (33.3 t/ha), Impala (31.7 t/ha), Zhukovskiy ranniy (29.0 t/ha), Predgornyy (27.7 t/ha) and Primobella (27.7 t/ha), as well as hybrids No.12.40/17 (43.1 t/ha) and No.13.61/61 (38.8 t/ha) were distinguished by yield.

The economic efficiency of the cultivation of grapes as a branch of agriculture depends on the adaptation of grape varieties to the soil and climatic conditions of the place of growth. When developing new agricultural practices and technological solutions for the cultivation of grapes, it is necessary to assess the econom-ic efficiency of the proposed innovative ap-proaches. The cultivation of such grape varie-ties is becoming important and relevant, which, with high productivity and the use of differen-tiated care technology, require minimal costs when servicing the bushes and harvesting. In-creasing labor productivity in the viticulture industry is the most important condition for the intensive development of production. One of these conditions today is the formation of a bush according to the technology element, the shape of a bush AZOS-1, which allows to re-duce the cost of care and harvesting of grapes. The conducted research on the technology of cultivation of table grape varieties in connec-tion with the use of a new form of bush made it possible to economically substantiate the economic efficiency of growing grapes.
