The impact of soil treatments and fertilizer application rates on increasing the yield of winter wheat varieties in southeastern Kazakhstan

New and resource-saving tillage technologies meet the requirements of soil and environmental agriculture to a greater extent than traditional ones (soil structure disturbance, degradation, erosion, etc. are excluded). In agricultural culture, including in irrigated agriculture of irrigated regions of Kazakhstan, new, non-traditional approaches based on the cultivation of field crops are required, ensuring the achievement of potential opportunities for varieties and hybrids of cultivated crops, with the aim of rational use of land and water resources, as well as preserving and increasing potential soil fertility. The article provides long-term experimental data on the advantages of resource-saving technologies and their positive impact on the quality and cost of crop production, which compete with previously used traditional technologies. The purpose of our research is to determine the effectiveness of tillage, the seeding rate of different varieties of winter wheat and the dose of fertilizers to obtain a high yield of grain with the best qualities. In the conditions of semi-secured bogara in the south-east of Kazakhstan, plowing to a depth of 20-22 cm and minimal tillage turned out to be the optimal sowing period for the second with a seed sowing rate of 3 million. germinated seeds per hectare and with the addition of 60 kg of nitrogen and phosphorus fertilizers. The optimal sowing period with zero tillage was the third with a seed sowing rate of 3 million. germinated seeds per hectare and with the addition of 60 kg of nitrogen and phosphorus fertilizers.
