THE EFFECT OF STIMULANTS ON CROTALARIA HAY YIELD AND QUALITY INDICATORS

Abstract

this article describes the effect of different biostimulants on hay yield and quality indicators of Crotalaria juncea in the cultivation of non-traditional leguminous plant Crotalaria juncea in the conditions of meadow gray soils of Jizzakh region. In order to get a high-quality hay crop from Crotalaria, it should be sown at the rate of 18 kg per hectare in the third ten days of April and along with sowing, 1.0 l of Geogumat biostimulant and 1.8 l at the time of 3-4 true leaves of the growing season, during the weeding period 500.0 /ha higher yield of blue mass was obtained when applied at the rate of 1.8 l/ha, 66.4 c/ha compared to the control option without biostimulant, 32.2 c/ha compared to the 6th option where Geohumat biostimulant was applied only with planting; With the planting of Geohumat biostimulator at the rate of 1.0 l/t and 1.4 and 1.6 l/ha in the 3-4 true leaving and branching periods, an additional yield of 24.5 and 15.8 c/ha was obtained compared to the 7th and 8th options. Also, the amount of nitrogen in crotalaria hay is 1.9-3.3%, and the amount of nitrogen is 0.4-1.4% higher in the options with stimulants than the control option, and the total proteins are 13.2-17.0%. It was explained that the biostimulant of Geohumat was 3.8% more compared to the control option in the options used at the rate of 1.0 l/t and 1.6 and 1.8 l/ha in the 3 4 true leaving and branching periods.
