Abstract

Eighteen sweet sorghum genotypes including two checks (CSV 19SS and SSV 84) were studied for dry matter positioning in kharif and rabi 2009. The results revealed that the proportion of dry matter accumulation diverted to stalk (stem) was substantially greater in kharif than rabi season. The post rainy crop gave 18.9% less total dry matter than kharif season. The genotypes RSSV 106, CSV 19SS, RSSV 138, RSSV 167, RSSV 82 and RSSV 99 during kharif season, while the genotypes RSSV 138 and RSSV 167 during rabi produced the higher total dry matter. The sweet sorghum genotypes accumulated higher dry matter during kharif season and translocated 13.33, 56.25 and 30.42% for leaf, stem and panicle development, respectively. During rabi season, it translated 10.85, 50.58 and 38.57 for leaf, stem and panicle development, respectively.
