摘要: High energy sorghum (Sorghum bicolor (L.) Moench) cultivars have been recently developed for grain and biomass production. Whole plant utilization is the target of this concept. The objective study was to identify relationship between harvest date yield. Experimental trials were conducted with cultivar BR 505 in years 1984/85, 1985/86 1986/87 determine its performance as a high crop. sugar yields obtained at physiological maturity stage plants. Sucrose total sugars increased continually from visible spikelet maturity. However, reducing level showed fall over same period. In 1984/85 yield 38.9 52.0 t/ha respectively. Late sowing which occurred year elimination supplementary N fertilization reduced significantly well stalks. Grain production complementary not affected significantly.
