The role of an agricultural forecrop in increasing the yield of winter wheat

The article presents data on the study of the influence of an agricultural forecrop on the yield of winter wheat varieties Moskovskaya 40 and Nemchinovskaya 17. The experiments were carried out in Ryazan region, Russia, on dark gray forest soils of Malinki enterprise in Mikhailovsky district. The most effective forecrop in the experiment was vetch-oat mixture for variety Nemchinovskaya 17, with the following yield structure: grains per spike are 46.8 pieces, 1, 000 seeds weight is 50.4 grams, with productive tillering of 1.80. On average, for two years, the maximum yield was observed in the variant with variety Nemchinovskaya 17 according to forecrop of vetch-oat mixture for green fodder (44.4 dt/ha) and in the variant with variety Moskovskaya 40 a forecrop was pea-oat mixture for green fodder (41.1 dt/ha). In studies, the maximum profitability was noted on the variant with forecrop of vetch-oat mixture in variety Nemchinovskaya 17 (153.1 %). In general, the profitability of the options was 109.5-153.1 %, that is highly profitable for agricultural crops in the region.
