FIELD: agriculture. ^ SUBSTANCE: method involves determining dose of nitrogenous fertilizers to be introduced and amount of precipitations for May; forecasting yield of corn for silage from mathematical dependence: Y=16.3+0.15N-0.1 Pm, R=0.82, where Y is yield of corn for silage, t/hectare; N is dose of nitrogenous fertilizers of from 11.5 to 119.9 kg/hectare of effective substance; Pm is amounts of precipitations for May of from 17.7 to 104 mm; R is coefficient of multiple correlation. ^ EFFECT: reduced labor intensity and increased precision in forecasting yield of corn for silage. ^ 1 tbl, 1 ex |
