Effect of Nitrogen Fertilization on Yield and Economic Efficiency of Cultivation of Winter Wheat Varieties and Lines

There are presented the results of the evaluation of the economic efficiency of winter wheat varieties Moskovskaya 39, Moskovskaya 28, Vasilievna, and a line Erythrospermum 606/19 cultivation depending on the level of nitrogen nutrition (N0, N60, N120, N180, N240 kg a.i./ha). The analysis showed that the increase in fertilizer dose contributed to the growth of yield and net income, with the highest economic efficiency achieved at application of N180–N240, where the maximum value of conditional net income and profitability were observed.
