Abstract :
Thirteen sorghum genotypes including four checks were evaluated for key physiological parameters that
help to survive under drought conditions. This experiment was conducted in root box structure by maintaining medium type of soil. The root number, length, volume and fresh mass all these root parameters were significantly higher in irrigated condition than rainfed condition. Under irrigated condition highest root number (82.33), root
length (97.67 cm), volume (136.00 ml) and fresh mass (164.00) was recorded by genotype CRS–19 while same genotype also recorded highest root parameters under rainfed condition. Moisture limitation under rainfed condition also
decreased chlorophyll content, photosynthesis rate, grain and fodder yield. Genotype CRS– 19 was also found superior
for root parameters , morpho– physiological , yield and yield contributing characters under rainfed and irrigated condition.
