A field experiment was conducted during 2002 to 2003 to study the effect of pre-sowing seed treatment with water soaking, 1% KCl, 1% KH 2PO 4, 0.1% (NH 4) 6MO 7O 24 4H 2O, rhizobium culture and foliar spray of nitrate salts with 0.25% KNO 3, 0.50% KNO 3, 0.203% Ca (NO 3) 2 and 0.406% Ca (NO 3) 2 on growth and yield of greengram [Vigna radiata (L.) Wilczek] in Gangetic alluvial (Entisol) land at the experimental farm of the Calcutta University, Baruipur. Pre-sowing seed treatments improved growth and physiological parameters like leaf-area index, crop growth rate, relative growth rate and net assimilation rate; yield attributes and increase of grain yield by 14 to 86% over the control. Pre-sowing seed treatment with rhizobium culture and 0.1 % (NH 4) 6MO 7O 24, 4H 2O exerted most conspicuous effect on growth and yield attributes and thereby resulting in 86 and 61% increase in grain yield respectively over dry seed (control). Foliar spray of nitrate salts during 50% flowering stage showed beneficial effect on growth parameters, and yield attributes and recorded higher gram yield ranging from 7 to 23%. Among the foliar spray treatments, spray of 0.406% Ca(NO 3) 2 and 0.5% KNO 3 exhibited maximum increase in grain yield by 23 and 19% respectively over the control. Pre-sowing seed treatment with rhizobium culture along with foliar spray of 0.406% Ca(NO 3) 2 proved most beneficial in greengram production.
