A field experiment was conducted in the experimental farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal during 2009-2010 to study the effect of organics on yield, uptake and economics of green gram (Vigna radiata L.). The experiment was laid out in randomized block design with 12 treatments. Cultivar SML-668 was used in the trial. Results of the experiment revealed that average pod/picking, pod length, number of grains/pod, 100 pod weight and test weight was found to be highest under T4 (Neem cake @ 3.0 t ha-1) followed by T10 (NC @ 1.5 t ha-1+ PM @ 1.5 t ha-1) and T9 (VC @ 1.5 t ha-1+ NC @ 1.5 t ha-1). Based on pooled data treatment receiving neem cake @ 3.0 t ha-1 recorded highest grain yield of 847.50 kg ha-1 which was statistically at par with T9 (837.11 kg ha-1), however T11 (100 % RDF) fetched highest B:C ratio (2.58), might be due to lower treatment cost.
