Abstract: Reduced soil tillage is a powerful means to mitigate soil degradation. However, in arid climates, no-till rainfed technologies often result in yield drop due to lack of soil moisture and mineral nutrition. Rainfed production of winter wheat using direct sowing and diversified fertilization in South Kazakhstan was studied in 2019–2020. Eight field-scale treatments using nitrogen and phosphorus fertilizers were studied for biometric parameters of winter wheat. An economic profitability of the amendments used was assessed. The soil managed to accumulate productive moisture to support plants’ needs during formation of productive organs. Use of phosphorus fertilizer at direct sowing accelerated grain maturation, and the combination of phosphorus and nitrogen fertilizer lengthened the growing season. The highest production cost of 1 tonne of grain was in the plots that did not receive any amendments, and the lowest cost was in the treatment with use of plant growth stimulants together with micronutrient fertilizer. For the first time, optimization of the soil nutritional regime with consideration of the biological and phenological demands allowed for the balance of the plant nutrition and cost efficiency of grain production with direct sowing of winter wheat in dry conditions in South Kazakhstan.
