 ABSTRACT

A field experiment was conducted to study the photothermal requirement of chickpea cultivars during rabi season of 2018-19 and 2019-20 at Regional Agricultural Research Station, Nandyal. The experiment was laid out in factorial RBD with three replications consisted three sowing dates 1st fortnight of October, November and December and fifteen genotypes viz., NBeG 47, NBeG 49, JG 11, Jaki, NBeG 452, NBeG 738, NBeG 776, NBeG 779, NBeG 857, NBeG 119, NBeG 399, NBeG 440, NBeG 458, Vihar and KAK2. The genotypes were evaluated for various morpho-phenological and heat units accumulation under different dates of sowing. A significant genotypic variability was recorded in plant height, number of branches, phenological stages and photothermal indices viz growing degree days (GDD), heliothermal units, photothermal units and heat use efficiency. Results revealed that duration of phenological stages and thermal unit from sowing to maturity decreased with successive delay in sowing. Crop sown during November produced significantly higher seed yield as compared to October and December sowings. Among the desi genotypes NBeG 779 and in kabuli genotypes NBeG 440 exhibited significantly higher seed yield.
