The presented article reveals the extent of mineral fertilizers impact on plant growth and development, and the ripening periods of a new spring wheat (Triticum aestivum L.) cultivar Stolypinka. The research objectives included the study of the influence of mineral fertilizer rates on yield structure, productivity, grain quality and economic efficiency of the variety Stolypinka. Field observations and the laboratory analysis of the data obtained proved the positive effect of mineral fertilizers on the yield structure components (the amount of productive stems, the number of kernels in a spike, the weight of 1000 seeds) in the studied cultivar. As a result of the research it has been found that the application of fertilizers at the rate for the planned yield is optimal for obtaining the maximum yield 3.5 t/ha of good quality grain containing the crude protein 15.8 % and gluten 32.3 %. In terms of economic efficiency, at the rates of fertilizers application N30 and N60 we have got the highest payback output (8.2 and 9.0 thousand rub./ha, respectively) and the lowest prime cost of 1 t grain (4.6 and 4.7 thousand rub./ha, respectively). The highest level of profitability (92.3 %) was observed in the option with the application of sole nitrogen at the rate 30 kg of active substance per 1 ha. Of the variants with a complex mineral fertilizer, using N60P45К45 is the most expedient in case of the gross grain harvest in the amount recouping the invested production costs.
