Abstract

Five varieties of Sorghum bicolor: Jawahar 69, MP Chari (multicut), Vidisha 60-1, Jawahar 6 and Jawahar 30 (single cut), were selected to study the fluctuation in the amount of prussic acid at different growth stages, and the crude fibre, crude protein, sugar, fat and mineral constituents at harvest. Jawahar 6 gave the highest green-fodder yield (36700 kg/ha), medium DM percentage and the lowest amount of hydrocyanic acid at every stage of growth. It proved fairly safe at 35 days of growth for feeding to animals, whereas other varieties contained toxic amounts of HCN even at 44 to 60 days of growth. Jawahar 6 gave the lowest percentage of crude fibre (29.61), the highest percentage of sugar (12.27), protein (6.21), fat (2.75), CaO (0.781), MgO (0.580), P2O5 (0.294), K2O (2.67), Na2O (0.060) and S (0.095). There was a high positive correlation between green-fodder yield and its constituents, but a negative correlation with HCN and crude fibre.ADDITIONAL ABSTRACT:Of five varieties studied, Jawahar 6 gave the highest green-fodder yield, had an intermediate dry-matter percentage and showed the lowest hydrocyanic acid (HCN) content at every growth stage. It was fairly safe as animal fodder after 35 days of growth whereas other varieties still contained toxic amounts of HCN after 44 to 60 days. Jawahar 6 had the lowest content of crude fibre and highest contents of sugar, protein, fat and minerals
