The article presents data on the study of influence of planting dates, planting schemes and doses of mineral fertilizers on the formation of yield of seed and product fractions of potato varieties of Smolensk selection Zabava and Smolyanochka. he research was carried out on the basis of FSBSI FSC LK (former FSBSI Smolensk GOSHOZ) on sod-podzolic medium loamy soil. Observations of the growth and development of potato plants in the studied varieties showed that the maximum number of stems was observed with the placement scheme of 70x25 cm against the background of mineral fertilizers N60P72K90. For the Zabava variety, the optimal planting time was May, 8, for the Smolyanochka variety-May, 14. In General, the Zabava variety had a higher stem-forming ability. The maximum yield of both varieties was obtained on a mineral ground N60Р72К90. The highest yield of tubers of seed fraction was noted at 70x25cm scheme and the planting date of May, 14. The maximum yield of food potatoes in the Zabava variety was obtained when the planting date was May, 8, and in the Smolyanochka variety-May, 14. It was established that the variety Zabava, regardless of plantig time, was affected by tubers with scab and foot rot. In the Smolyanochka variety, only scab was observed from diseases.

Dry matter yield is an objective indicator of assessing the productivity of corn hybrids grown for silage and green fodder. The aim of the work was to identify optimal planting dates to obtain maximum yield of dry matter at the late milk stage of development for hybrids of corn depending on groups of maturity under rain-fed conditions of the Crimean steppe zone. The sowing dates of the field experiment were on April 5th, 15th, and 25th. We studied hybrids of corn of different groups of maturity. Soil – chernozems southern low-humus. Meteorological conditions in 2016 were characterized by increased moisture availability (Selyaninov Hydrothermal Coefficient (HTC) 1.46). In 2017, severe drought was noted (HTC 0.34). Moisture availability was insufficient in 2018 and 2019 (HTC 0.79 and 0.78, respectively). In 2016-2019, the best planting date for hybrid ‘Nur’ was April 15th; the dry matter yield in the late milk stage was 6.69 t/ha. For the medium- early hybrid ‘Mashuk 220 MV’, the best sowing dates were April 15th and 25th; dry matter yield was 5.95 and 5.78 t/ha, respectively. Hybrid ‘Mashuk 355 MV’ demonstrated higher dry matter yield on April 5th and 15th (7.12 and 6.99 t/ha). However, the planting date of April 25th led to significant yield decreased (to 6.1 t/ha).

The Impact

The impact of today’s optimal planting dates on sudden death syndrome (SDS) (caused by Fusarium virguliforme) development and soybean yield loss are not yet well understood. Field trials established in Hancock, Wisconsin during 2013 and 2014 investigated interactions between planting date and cultivar on SDS development and soybean yield. In 2013, disease index (DX) levels differed among cultivars, but results showed no difference between the 6 May and 24 May planting dates. Significantly lower DX levels were observed for the 17 June date. Greatest yields were found in the 6 May planting date, and yield losses were 720 (17%), 770 (20%), and 400 kg ha−1 (12%) for the 6 May, 24 May, 17 and June planting dates, respectively. In 2014, cultivars again differed for DX, but results showed highest DX levels in the 5 May planting date, with little disease observed in the 22 May and 11 June dates. Yield losses were 400 (12%) and 270 kg ha−1 (9%) for the 5 May and 22 May dates, respectively, but no difference was found in the 11 June date. Despite the most symptom development, these results suggest early May planting coupled with appropriate cultivar selection provides maximum yield potential and profitability in Wisconsin.

Control Analysis

Barley is a crop, requires the availability of available nutrients in the soil, especially at the be-ginning of the growing season. The aim of the research was to determine the effectiveness of the aftereffect of using vermicompost when growing spring barley on different backgrounds in the Donetsk region. The studies were carried out according to the methodology of the field experiment of B. A. Dospehova. Research methods: field, supplemented by analytical studies, measurements, calculations and observations. The studies were conducted in 2017–2019 by laboratory-field method in field crop rotation in the experimental sections of the Donetsk SSES NAAS. The repetition in the experiments is 3-fold. The location of the plots is systematic. The soil is alkaline-chernozemic carbonate, having an average supply of mineral nitrogen and mobile phosphorus, low – potassium. The humus content of 4,2 % indicates a high potential soil fertility, but to realize the potential of the culture, additional application of phosphorus-potassium fertilizers is necessary. The technology for growing crops is generally accepted for the farms of the region, with the ex- ception of the factors studied. Variety of barley spring Avers. The experience scheme provides for: control (without fertilizers); background – saturation of crop rotation with vermicompost granular 2 t/ha; background + N30P30K30; background + N60P60K60; N30P30K30. The use of organic fertilizers under the predecessor in crop rotation provided improve nutriti-on conditions for plants, which positively affected the growth and development of spring barley plants. So, on the variants with the use of mineral fertilizers, the highest indices of the number of productive stems and the structure of the crop were noted in the background. The variant where N60P60K60 was added in the background produced the largest mass of 1000 grains – 49,8 g, which is 4,6 % higher than the control. Analysis of the study indicates the positive effect of the aftereffect of organic fertilizer (ver-micompost) on the yield of spring barley. The maximum yield of spring barley was obtained against the background of aftereffect of vermicompost 2 t/ha and the application of mineral fertilizers N60P60K60 – 5,05 t/ha, but due to high production costs, the profitability level is 114,9 %. The application of organic fertilizers under the background provides a yield of 3,67 t/ha and the highest level of profitability of 140,6 %. The optimal technological option provides for the introduction of mineral fertilizers in the norm N30P30K30 amid predecessor saturation with vermicompost. This allows increasing the yield up to 4,90 t/ha (by 1,46 t/ha or 42,4 % to the control) and obtaining a profitability level of 136,1 %. The use only of mineral fertilizer N30P30K30 in severely arid weather conditions of the steppe zone allows increasing the yield by 0,70 t/ha compared to the control but, due to the high cost of pro-duction, leads to a low production profitability of 99,6 %. Key words: spring barley, background, vermicompost, mineral fertilizers, yield, economic effici-ency.

Relevance. The aim was to study the reaction of new potato varieties early ripening group Zabava and middle-ripening group Smolyanochka on the timing of planting and doses of mineral fertilizers for obtaining maximum yield of seed potatoes. As mineral fertilizers used azophoska, superphosphate and potassium chloride.Results. It was found that the variety Zabava compared to the variety Smolyanochka, had a higher stem-forming ability and exceeded the parameters of the stem in all variants of the experiment. This is due to the biological characteristics of the studied varieties, since the Zabava variety, unlike the Smolyanochka variety, had more multiple eyes on the surface of the tuber. Against the background of applying mineral fertilizers N60P72K90, the density of the stem was higher, compared with the background of applying N32P32K32 in both the Zabava variety and the Smolyanochka variety. It should also be noted that there was a tendency to reduce the stem at a later date of planting in all variants of the experiment. The percentage of viral diseases affected increased with later planting dates and was highest with the planting dates of 14 and 20 may. The highest yield of tubers of the seed fraction was obtained in the variant with a planting date of may 14 against the background of balanced doses of mineral fertilizers (N60P72K90) and amounted to 13.3 t/ha in the Zabava variety, 13.0 t/ha in the Smolyanochka variety. It should be noted that different backgrounds of mineral fertilizers did not have a significant impact on the percentage of potato tubers affected by diseases. At the same time, the incidence of tubers with diseases did not exceed the regulatory requirements of GOST R 53136 – 2008 "Seed potatoes. Technical conditions».

Inoculation of seeds of legumes (soybean - Glycine max L., mung bean - Phaseolus aureus L., wild beans - Phaseolus) grown as a secondary crop after winter wheat before sowing with nitragin and application of mineral fertilizers in different doses affected the amount of endogenous bacteria formed in the plant root as well as the agrochemical properties of the soil. Inoculation of legume seeds with nitragin before sowing and application of mineral fertilizers at different rates increased the amount of humus in the topsoil (0-30 cm) layer by 0.025-0.029% compared to the initial values, and the total nitrogen content by 0.009-0.012%. The formation of endogenous bacteria in the root of the plant was inoculated with nitrogen before sowing the seeds of soybean, moss, bean crops. The amount of legumes was 22.7-36.7 pieces in the variant, in which the mineral fertilizers N30 R90 K60 kg/ha was applied, whereas it was 12.0-15.6 pieces in the variant without any mineral fertilizers.

The effect of planting dates between September 30 and November 30 on the yield and some fibre properties of two cotton cultivars has been studied over three seasons. The yield of the commercial cultivar (Deltapine Smoothleaf) fell by an average of 20 kg ha-1 day-1 delay in planting after October 20, earlier planting dates having equal yields, producing a plateau effect. The yield of an early maturing cultivar (Short Sympodial) fell linearly by 11 kg ha-1 day-1 delay in planting. Planting dates after mid-October had an adverse effect on micronaire in the commercial cultivar, but lint length and strength were not affected. Thus maximum yield and micronaire for plantings after mid-October came from the early cultivar. Tolerance to low temperature is an important factor in cultivar earliness, and accounts for the performance of Short Sympodial in these experiments. The number of days from first flower to first frost was as reliable as growing degree days in explaining yield variation within a cultivar

Relevance For the successful introduction of a new variety of potatoes into production, it is important to know the technological parameters of its cultivation, both for seed and food purposes. Methods Studies on the timing, planting schemes and doses of mineral fertilizers, providing maximum yield of seed and food tubers of a new potato variety Smolyanochka breeding Smolensk GOSHOS, were conducted in 2017-2018. Experience, observations and accounting were carried out according to generally accepted methods. The studies were conducted in the field short-term experience of the Smolensk Institute of agriculture (ex. Smolensk GOSHOS) on sod-podzolic medium-loamy soil with low humus content, weak acid reaction of the soil environment, high content of mobile phosphorus and high potassium content. Results Observations of the growth and development of potato plants of the Smolyanochka variety showed that the length of the growing season decreased from early planting to later. Planting schemes and fertilizer doses did not have a significant impact on the duration of development phases in all variants of the experiment. The density of the stem per unit area decreased by 5-18% from earlier planting dates to later and increased with an increase in the dose of mineral fertilizers to N60P72K90 by 12-28%, compared with the background of N32P32K32. The highest percentage of plant viral diseases during the growing season was observed with a more thickened planting scheme (70x25 cm) and increased with later planting dates. The maximum yield of potato tubers when grown for both seed and food purposes was noted against the background of mineral fertilizers at a dose of N60P72K90 when planted earlier. Post-harvest tuberous analysis of potatoes showed that all the studied variants of the experiment did not have a significant impact on the affection of potato tubers with fungal diseases.

The article summarizes the results of studies (2013 and 2018) conducted on leached heavy loam Chernozem in the Republic of Mordovia. The object of study is oats (Horizon variety). In the experiment, against the background of plowing, tillage and disking, the effect of mineral fertilizers was studied, which were represented by a complete mineral fertilizer (N32P32K32 –background), and fertilizing with mineral nitrogen in doses of 30 and 60 kg of active gradient/ha against this background. Analysis of oat yield shows that the collection of grain plowing in options without the use of mineral fertilizers (2.34 t/ha) had an advantage over the tillage and disking (2.15 and 2.04 t/ha), and in general, the experience increased the yield of oats by 0.43 and 0.53 t/ha. The maximum yield increases from the use of mineral fertilizers were obtained from the background of plowing, their value ranged from 0.49 to 1.03 t/ha compared with the option without fertilizers, there were less increases on the background of non-dump treatment of 0.21–0.57 t/ha and disking of 0.22–0.62 t/ha. Fertilizing with mineral nitrogen at a dose of 30 kg of active gradient/ha regardless of the methods of tillage showed an almost equivalent increase in the yield of oats by 0.20–0.24 t/ha compared with the background options (2.83, 2.36 and 2.26 t/ha, respectively, plowing, dump-free processing and disking). The most effective (an increase of 0.54 t/ha) was fertilizing with nitrogen at a dose of 60 kg of active gradient/ha against the background of applying a full mineral fertilizer using plowing.

Проблема и цель. В настоящее время при выращивании картофеля отмечается негативная тенденция, заключающаяся в использовании повышенных доз минеральных удобрений при одновременном сокращении внесения органики. Альтернативой традиционным минеральным удобрениям могут стать комплексные микроудобрения и гуминовые препараты. Цель работы – изучение влияния некорневых подкормок комплексными микроудобрениями и гуминовым препаратом на биометрические параметры роста и развития картофеля. Методология. Исследования проводили на двух сортах картофеля раннеспелой группы – Гала и Латона. Для некорневых подкормок использовали микроудобрения Страда N, Страда Р и гуминовый препарат Экорост. Картофель выращивали в 2017-2019 гг. в учебном хозяйстве РГАТУ на серой лесной почве. Варианты опыта: 1) контроль – без вегетационной обработки; 2) обработка гуматом Экорост в дозе 0,2-0,4 л/га; 3) обработка микроудобрением Страда N в дозе 3-5 л/га; 4) обработка микроудобрением Страда Р в дозе 3-5 л/га. Обработку проводили дважды – при появлении полных всходов и через 14 дней после первой. Остальные элементы агротехники культуры не различались по вариантам и были общепринятыми для нашей зоны. Определение биометрических параметров картофеля проводили по методике ВНИИКХ (1967) в три срока: в фазу бутонизации, цветения и начала отмирания ботвы. Результаты. Экспериментально доказано положительное действие некорневых подкормок комплексными микроудобрениями и гуминовым препаратом на динамику изменения таких биометрических параметров картофеля, как высота растения, количество стеблей, масса и площадь листьев, масса клубней. Заключение. Наиболее эффективным вариантом является некорневая подкормка микроудобрением Страда Р, использование которого улучшает условия развития растений, ускоряя рост ассимиляционного аппарата, что в конечном итоге отражается на продуктивности картофеля. Problem and purpose. Currently, when growing potatoes, there is a negative tendency, which consists in the use of increased doses of mineral fertilizers while reducing the introduction of organic matter. Complex micronutrient fertilizers and humic preparations can become an alternative to traditional mineral fertilizers. The purpose of the work is to study the efect of topdressing with complex micronutrient fertilizers and a humic preparation on biometric parameters of growth and development of potatoes. Methodology. The research was carried out on two varieties of early maturing potatoes - Gala and Latona. For topdressing, micronutrient fertilizers Strada N, Strada R and humic preparation Ekorost were used. Potatoes were grown in 2017-2019. in the educational farm of RSATU on gray forest soil. Experimental options were as it follows: 1) control - without vegetative treatment; 2) treatment with humate Ekorost at a dose of 0.2-0.4 l/ha; 3) treatment with micronutrient Strada N at a dose of 3-5 l/ha; 4) treatment with micronutrient Strada Rat a dose of 3-5 l / ha. The treatment was carried out twice - when full shoots appeared and 14 days after the frst treatment. The rest of the elements of agricultural cultivation did not difer in variants and were generally accepted for the zone. The determination of biometric parameters of potatoes was carried out according to the method of VNIIKH (1967) in three terms: in the phase of budding, fowering phase and the beginning of top withering away. Results. The positive efect of topdressing with complex micronutrients and a humic preparation on the dynamics of changes in such biometric parameters of potatoes as the plant height, number of stems, mass and area of leaves, mass of tubers has been experimentally proved. Conclusion. The most efective variant is topdressing with Strada R micronutrient, the use of which improves the conditions for plant development, accelerating the growth of the assimilation apparatus, which ultimately afects the productivity of potatoes
