CREATION OF EFFECTIVE COMBINATIONS OF BIOFERTILIZERS USED IN SUNFLOWER GROWING

Abstract

The article presents information on the effect of applying organomineral fertilizers on the formation of their crop structure to the sunflower crop planted as a secondary crop in Uzbekistan. In this combination, the weight of 1000 grains and the yield rate of 1000 grains in the 4th variant were the highest among the variants, which were 76.4 grams and 37.23%, respectively. The yield was 32.1 c/ha in option 4 and 30.6 c/ha in option 8, which was 8.2 and 7.7 c/ha higher than the corresponding control options.
