The experiment was conducted with 18 sweet sorghum genotypes during kharif and rabi 2009. The heat unit efficiency studies revealed that the heat unit efficiency (HUE) for cane yield and dry matter production was higher during kharif season, while lower during rabi season. The HUE for grain yield was higher during rabi season than kharif season. The genotypes RSSV-260, RSSV-138, CSV-19SS, RSSV-106 and RSSV-167 in kharif and RSSV-138, RSSV-106, RSSV-192 and RSSV-167 in rabi season were observed to be the most efficient in conversion of absorbed heat into green cane yield. The genotypes RSSV-167, RSSV-138, RSSV-82, RSSV-192, RSSV-104, CSV-19SS and RSSV-106 during kharif season and the genotypes RSSV-138, RSSV-167, RSSV-106, RSSV-192 and CSV-19SS during rabi season were observed to be the most efficient in conversion of absorbed heat into dry matter production. As regards grain yield, the genotypes RSSV-82, RSSV-191, RSSV-104, RSSV-120, RSSV-166, RSSV-138, RSSV-106, RSSV-167, SSV-84 and CSV-19SS in kharif and the genotypes RSSV-82, CSV-19SS and RSSV-99 in rabi season were observed to be the most efficient in conversion of absorbed heat into grain yield.
