Abstract

An experiment was conducted at Uttar Banga Krishi Viswavidyalaya, Pundibari, Cooch Behar, West Bengal during the Pre-Kharif season of 2008-2009 in a randomized com­plete Block with twelve treatments to study the effect of organic sources of nutrients on Agronomic efficiency, Partial factor productivity and Seed yield of groundnut. Pooled data over two years revealed that application of PM @ 2.5 t ha-1 + NC @ 2.5 t ha-1 + VC@ 2.5t ha-1 + PC @ 2.5 t ha-1 produced 19.32 and 267.05 % more seed yield of groundnut over 100 % RDF and control, respectively. Among the sole application of organics phosphocompost @ 5 t ha-1 recorded higher seed yield, though all the sole applied organic treatment recoded lower seed yield than 100 % RDF. Maximum partial factor productivity (PPFN) of 63.02 kg seed kg-1 N and agronomic efficiency (AEN) of 42.53 kg seed kg-1 N of groundnut was observed with 100 % RDF. Partial factor productivity of phosphorus (PFPP) was found to be maximum (27.33 kg seed kg-1 P) under neem cake @ 5 t ha-1, where as phosphocompost @ 5 t ha-1 gave significantly maximum (161.80 kg seed kg-1 K) partial factor productivity of potassium (PFPK). Highest internal efficiency (13.71 and 17.35 kg seed kg-1 N uptake) was obtained from vermicompost @ 5 t ha-1 during 2008 and 2009, respectively.
