Abstract

An experiment was carried out on an experimental field of Hanoi University of Agriculture to determine nutritive values of some selected sorghum varieties grown during the winter period of the year. Results showed that all the selected sorghum varieties were tolerant to drought and low temperature condition of winter and gave very high green biomass yield (97.99-133.99 tons/ha/3 cuts). In addition, the sorghum varieties also gave relatively high seed yield (1.05-2.43 tons/ha) which can be used as animal feed or human food. The chemical composition of the sorghum varieties was characterized by low crude protein content (10.08-11.39%) and high crude fiber (27.03-28.67%). The investigated sorghums contained a noticeable amount of HCN (17.8-20.8 mg/kg) which is harmfull to animal health.  Among the investigated varieties sorghum S4 (Ban Pho-Tun Chua, Cao Bang) and sorghum S5 (M90386, imported from India) gave the highest green and seed yield (125.66 &133.99 tons of green biomass/ha/3 cuts, and 2.12 &2.43 tons of seeds/ha, respectively)
