Influence of biochemicals on the productivity of maize green mass and grain cultivated on sod-podzolic light loamy soil

The paper discusses the effects of PolyFunKur and Agromik biofertilizers on the biometrics of maize, as well as on its green mass and grain yield on sod-podzolic light loamy soil. Methods: phenological, agrochemical, microbiological. The use of Agromik and PolyFunKur biochemicals increases biometric indicators of maize during its development phases in comparison with the control. The highest yield of the maize green mass for silage was in the test with the treatment of seeds and vegetative organs in the tillering phase in Poli funk ur. In this test, the yield increased up to 57.2 c/ha over the control. In the agromik test, the increment of green mass was slightly lower, i. e. 43.3 c/ha over the control. Comparison the polylinker and agro Mik tests reveal the difference to be 13.9 centners/ha. The highest maize grain yield was noted in the PolyFunKur test to be 1.9 c/ha more than in Agromik test and 7.3 c/ha more than in the control.
