The effect of mineral fertilizers on the yield and quality of winter wheat varieties Gubernator Dona, cultivated by non-fallow predecessors

In the experience laid down in the station, K the Department of agricultural chemistry and mineral nutrition of plants the Federal agrarian scientific centre of Rostov in Rassvet of the Rostov region studied the effect of mineral fertilizers on the yield and quality of winter wheat varieties, Gubernator Dona, cultivated by non-fallow predecessors. As a result of the research, the positive effect of the studied doses on crop yield and protein content in winter wheat grain was established. The greatest increase in protein in peas and spring wheat was obtained by applying 100 kg of nitrogen and 90 kg of potassium. For maximum yield of winter wheat Gubernator Dona in the cultivation on non-fallow predecessors, it is necessary to make a complete fertilizer dose of N100Р60К90 that allows you to crop within 66.1–72.15 centner per hectare. The maximum return is achieved when using nitrogen fertilizer in a dose of 60 kg per hectare, spring wheat predecessor and the application of phosphate fertilizers in a dose of 60 kg per hectare precursor peas.
