FIELD: agriculture, in particular, determining herbage yield without weighing. SUBSTANCE: method involves selecting plots for estimation; determining average height of herbage on selected plots and estimating yield. Biological yield is estimated by formula: y = 1.16x - 14.1, where y is biological yield of natural herbage, centner/hectare; x is herbage height, cm. EFFECT: simplified and efficient method and provision for obtaining precise data. 2 tbl, 1 ex
