Abstract: A field experiment was conducted at the Agricultural farm of Visva-Bharati University, Birbhum, West Bengal during Pre-kharif (Summar) season of 2012, to study the effect of foliar spray of seaweed extracts (prepared from Kappaphycus alvarezii & Gracilaria crassa) on the growth and productivity of black gram. The foliar spray was applied thrice at different concentrations (0, 5.0, 7.5, 10.0 and 15.0% v/v) of seaweed extracts. Foliar applications of seaweed extracts significantly enhanced the growth and yield attributes. The highest grain yield was recorded with applications of 15% Kappaphykus + recommended dose of fertilizer which at par wth 15% Gracilaria extracts + RDF resulting in an enhanced by 51 and 44% grain yield, respectively compared to the water applied plots. The highest straw yield was also achieved with the application of 15% seaweed extracts. The nutrient uptake (N, P and K) which influenced due to the application was also with seaweed extract.
