Abstract
The article presents data on the yield of green mass of grain sorghum harvested in the phase of the beginning of panicle and milky-wax ripeness of grain. The variability of the yield of green mass is shown with varying the main agrochemical parameters of sod-podzolic sandy loam soil. The regression equations are presented that describe the pair and multiple correlation of the yield of green mass in both phases of mowing maturity with the exchangeable acidity of the soil, the content of humus, mobile forms of potassium and phosphorus. The quantitative parameters of the change in yield with an increase in the level of soil humus content, the content of P2O5 and K2O, and a decrease in the reaction of the soil environment are given.
