Abstract
Nitrogen (N) nourishment in legumes is essential for achieving greater productivity as biological nitrogen fixation by nodules in these crops ceases towards maturity. This study was conducted to elucidate the response of chickpea to foliar application of N through urea at differ-ent growth stages under irrigated conditions of Punjab, India. Plant nodule numbers, nodule dry weight and leghaemoglobin content increased significantly with foliar spray of 2% urea at different growth stages of crop over unsprayed control. Chlorophyll kinetics and highest quantum efficiency of Photosystem II was recorded with foliar spray of 2% urea at pod initiation stage. Yield attributes such as pods/plant improved significantly with 2% foliar spray of urea at different growth stages over no spray treatment. Foliar spray of urea (2%) at pod initiation stage recorded significantly higher grain yield thereby recorded highest gross returns, net returns and benefit cost ratio over unsprayed control.
