The efficiency of the use of biological products in cultivation of spring wheat in Western Siberia

Abstract

In an experiment on quasi-gleyed agrochernozem in the south of Western Siberia, it was found that biological preparations (biological fertilizers and growth stimulants) are effective when used for spring wheat by seed treatment method. With a yield of 2.41 t/ha in the control variant, the use of biological preparations contributed to the formation of 2.70-2.88 t/ha of grain. The greatest effect is obtained from the use of variants: azotovit + phosphatovit and azotovit + phosphatovit + potassium humate. The use of biofertilizers has a positive effect on the soil nitrate nitrogen and mobile phosphorus content. The use of stimulants did not significantly affect the fertility level. Biological fertilizers and growth stimulants had a positive effect on crop quality indicators. It was revealed that the sum of amino acids increases from 9.24% without fertilizers to the highest 9.81% in the variant with potassium humate.
