| Summary: | The article presents the results for 2004-2012 on study of comparative productivity of agricultural crops in crop rotations with legumes and cereals perennial grasses when using complex of agrochemicals. A study conducted in the Republic of Mordovia in the long-term stationary experiment on leached heavy loamy chernozem. Four factors were studied (3x2x2x5): liming, crop rotation, micronutrient fertilizers, mineral fertilizers. Doses of lime were calculated according to 0.5 and 1.0 hydrolytic acidity (GK). Rotations varied with cultivation of perennial grasses: lucerne and rump. Treatment of vegetative plants was carried out by liquid fertilizing-stimulating composition of trace elements (ZhUSS-2), 2.5 l/ha. Variants with fertilizers included three doses of nitrogen on the background of phosphorus-potassium fertilizer. The sequence of crops in grain-grass-till crop rotations - spring wheat with sowing of perennial grasses, grasses of 1st, 2nd and 3rd years of use, then the turnover of the soil - winter, spring wheat, soybeans, oats. The average annual productivity of legume crop rotation on the average for experience was 0.35 m GU/ha higher in compare with cereals crop rotation (2.51 t GU/ha). The action of lime was the most significant in the bean crop rotation, where the increase on the background of liming 0.5 GК was 0.13 t GU/ha. The effectiveness of crops treatment with preparation ZhUSS-2 was equivalent in both crop rotation (0.15 t GU/ha). |
