CROP STRUCTURE AND YIELD OF GRAIN LEGUMES DEPENDING ON AGRICULTURAL PRACTICES IN THE CONDITIONS OF THE FOREST-STEPPE ZONE OF THE VOLGA REGION
The influence of the main tillage and plant protection on the yield and its structure of grain legumes has been studied. Combined tillage with adaptively integrated plant protection increased the studied parameters by 5,4-8,7% compared to the minimum tillage and the first level of plant protection. The maximum yield was obtained on peas by the combined tillage in crop rotations of 2,65 t / ha, and with the minimum tillage – 2,36 t / ha. The effect of combined tillage on soybeans was also higher than on the minimum, where the yield was 2,25 t / ha and 1.94 t / ha, respectively. The yield of chickpea is also higher for combined processing – 2,27 t / ha, and at the minimum –1.94 t / ha. The yield of lupine for soil cultivation is 2,23 t / ha and – 2,00 t / ha.
