The purpose of the study was to evaluate the influence of mineral fertilizers and methods of basic tillage on the yield and oil content of sunflowers in the north of Kazakhstan. The experiment was conducted in the agricultural experimental Station Zarechnoye limited liability partnership with southern thin chernozem soils. Records and observations of the growth and development of sunflowers were carried out using modern methodological recommendations. The used agricultural technique of sunflower cultivation in the experiments was the one recommended for the study area. The authors studied new sunflower hybrids and different variants for the use of mineral fertilizers and methods of basic tillage. The paper concludes that it is important to use new sunflower hybrids Sumatra, Suzuka and Sumiko which achieve yields at the level of 1.34-1.46 c/ha with an oil content of 48.52-48.88%, which is the scientific novelty of the study. The combined use of mineral fertilizers according to the scheme N40P40 in the autumn + N20P20 in spring when sowing + N10P10 fertilizing in the conditions of the study zone increased the yield and harvest of sunflower oil to 1.34 and 0.65 t/ha. The no-till technique improved the biometric and productive yield indicators. In this variant, a high yield of sunflower was obtained (1.31 t/ha) with a high oil content (48.49%) and a higher oil yield of 0.63 t/ha was provided. These improvements in the quality and productivity of sunflower as the main oilseed crop are of significant importance for food security and sustainable agriculture in Northern Kazakhstan.

This article discusses the issue of digitalization of the agro-industrial complex, using the example of two locations of the same size, soil cover, predecessors, put up two sowing units "John Deere 1820", a navigation system was installed in one of the units. According to the results of the sowing works, we see a positive moment from the agronomical point of view in the reduction of the terms of work. The introduction of digitalization on the example of a farm provides an opportunity to clearly monitor the positive dynamics, both from an economic point of view and a positive impact from an agronomic point of view, that is, yield increase, soil improvement using the law of return of substances to the soil, in a word level of farming. The value of this article lies in the timely detection of the initial stage of development of plant diseases in order to take preventive measures to localize and eliminate them. Here, the timeliness factor will help prevent up to 40% of the potential yield loss from diseases and prevent a decrease in the quality of grain. If we recount it for the whole sown area of the republic, the benefit will be enormous.

The aim of the research is to carry out field and office work on conducting a sub-satellite survey on test sites of the Kostanay region of the Republic of Kazakhstan. Grain-sowing districts of the Kostanay region were selected as the objects of examination: Karabalyk, Fedorov, Mendykara, Uzunkol, Sarykol, Altynsarin, Kostanay, Denisov, Karasu, Taranov, Zhitikara, Auliekol, Kamysty, Naurzum. The determination of the reserves of productive soil moisture in the 0-100 cm layer by control points (100 points) carried out in the pre-sowing season of 2019 showed that the soils are characterized by satisfactory and, for the most part, insufficient moisture. The fields fixed in the coordinate system were evaluated by five indicators - pH, humus, nitrate nitrogen (N-NO3), mobile phosphorus (P2O5), and exchange potassium (K2O). Most of the soils examined had a soil solution reaction that was neutral or close to neutral. In terms of humus content, soils of the Karabalyk, Fedorov, Uzunkol and Sarykol districts had an average degree of availability, which exceeded the indicators of other districts of the Kostanai region and depended on the type of soil. The content of the basic elements of plant nutrition - nitrogen and phosphorus - varied within various limits, and, to a large extent, was determined by the previous culture, tillage, fertilizer application, and climatic conditions of the year. The level of exchangeable potassium in the soils of the examined districts of the Kostanay region was characterized as elevated or very high.

Перспектива развития сельского хозяйства в Казахстане набирает огромные темпы. Идет развитие деверсификации сельского хозяйства, увеличиваются площади и под масличные культуры. На сегодняшний день одной из перспективных и востребованных масличных культур является подсолнечник, площади возделывания которого увеличиваются с каждым годом. Также подсоднечное масло является самым востребованным продуктом среди населения республики. Отсюда возникает вопрос повышения урожайности подсолнечника, включая различные технологии возделывания, тем самым адаптируя их к агрометеорологическим и почвенным показателям региона возделывания. Цель данной работы заключалась в том, чтобы сравнительно изучить и оценить влияние минеральных удобрений на урожайность и масличность подсолнечника на Севере Казахстана. Эксперимент проводился в ТОО «Сельскохозяйственная опытная станция «Заречное» с южными маломощными черноземными почвами. Учеты и наблюдения за ростом и развитием подсолнечника проводились с использованием современных методических рекомендации.Агротехникавозделывания подсолнечника в опытах рекомендованная для зоны исследования. Изучали разные варианты использования минеральных удобрений. В работе сделан вывод о важности совмещенного использования минеральных удобрений по схеме N40P40 осень+N20P20 весной при посеве+N10P10 подкормка в условиях зоны исследований увеличило урожайность и сбор масла подсолнечника до 1,34 т/га и 0,65 т/га. Указанные улучшения качества и увеличения продуктивности подсолнечника как основной масличной культуры имеют значительное значение для продовольственной безопасности и ведения устойчивого сельского хозяйства в Северном Казахстане
