Abha Chauhan, Usha Parmar, Jagmeet Kaur and J.S. Sandhu

Abstract

Foliar spray application with SNP (Nitric oxide donor-150 and 300 μM) was undertaken at the vegetative stage (30 DAS, Days After Sowing) and repeated after 10 days till maturity in two chickpea cvs IC-424234 (chilling tolerant, CT) & PBG-1 (chilling sensitive, CS). SNP (150 μM) treated plants of PBG-1 recorded increased number of flowers plant-1, total number of pods plant-1, pod setting (%), percent filled pods, 100 seed weight, yield plant-1 & finally the total yield (kg/ha) as compared to those of the control plants, whereas in case of IC-424234 pollen viability (%) was recorded highest with SNP (150 μM) treatment as compared to PBG-1.
