Description |
A field experiment on different sorghum cultivars namely CSV SR, SPV 504, SPV 913, M 35-1 and SPH 504 was conducted in red sandy loam soils at the farm of National Research Centre for sorghum, Rajendranagar with a view to study their root growth, water extraction pattern, nutrient uptake and drought tolerance capacities. The stu~ies indicated that a maximum grain yield of 8730 kg ha was observed in SPV 504 followed by SPV 913, CSV SR, SPH 504 and M 35-1. A minimum quantity of wFter of 29.33 cm was extracted by CSV BR followed by pPV 504 which extracted 31.0 cm during the entire growth period. The maximum uptake of N a~~ Po observed in SPV 504 were 224.05 and 54.81 kg ha ris~ectively. A maximum drought tolerance index of 7.7 was observed in M 35-1 followed by 7.62 in SPV 504. A water extraction of 7.5 per cent lower, root contribution of 15.5 per cent higher and a grain yield of 34.9 per cent higher were observed in SPV 504 than in the local variety M 35-1. The studies clearly indicated that SPV 504 was found to be superior to CSV BR, SPV 913, M 35-1 and SPH 504 in extracting lower quantity of water, withstanding to relatively better drought conditions and in achieving maximum grain yields under rainfed conditions of agriculture in the red chalka soils of Rajendranagar.
