Abstract
Rapeseed productivity will not be very high. Therefore, it is necessary to study the effect of biologically active substances on the productivity and quality of spring rape. Biologically active substances have effective, fast-acting factors that contribute to improving the quality of crops and crop yields. With the help of which the metabolism changes, affects the chemical composition of plants, the accumulation of proteins, fats, carbohydrates and the quality and quantity of products. In this work the questions of efficiency of use of biologically active substances at cultivation of spring rape in the conditions of SKO are considered.
