The effect of biofertilizers on the productivity of oats and clover-thymopheic mixture in the conditions of the Non-Chernozem region

Abstract

In the link of crop rotation of fodder crops on sod-podzolic soil (83% of arable land) in the conditions of the Novgorod region, the use of Azotovite and Phosphatovite for the cultivation of crops on two backgrounds of mineral fertilizers was studied. The use of biofertilizers in technological operations twice (pickling of seed material and non-root spraying) against the background of full mineral fertilizer, in accordance with the plan, received the highest yield of cultivated crops: oat grains 4.3 t/ha and green mass of a clover-thistle mixture of 1 year of use (2 mowing) 60.9 and 2 year of use (1 mowing) 38.4 t/ha and the maximum nutritional value of feed per hectare: collection of dry matter 0.7, 15.2, 9.6; feed units–4.3, 13.0, 8.4 thousand tons; digestible protein 0.37, 1.16 and 0.74 tons with low energy intensity of production of cultivated crops 3.1, 0.7 and 1.0 GJ/thousand tons k units and high energy efficiency coefficients of 5.3, 16.1 and 12.5 units, respectively.
