Abstract
The article presents the results of studies of the effect of mineral fertilizers on yield of winter wheat cultivated on typical сhernozemic soils of forest steppe in Ukraine. A scheme of a field experiment was mathematically planned, that made it possible to process the data with modern statistical methods by a computer program. The optimum rate of fertilizer for winter wheat was the following: nitrogen - 65 kg/ha, phosphorus - 120 kg/ha P2O5. The authors developed a mathematical model of winter wheat yield forecasting for the typical сhernozemic soils of forest steppe in Ukraine. The main indicator of the mathematical model is an absolute term, which is equal to 65 kg/ha. Effect of factors (N, P, K) and their interaction increases the yield by 3.16 с/ha. The optimum rates of fertilizers for maximum yield, maximum profit, cost of power consumption and integrated indicator are determined.
