Abstract

To investigate the effect of integrated nutrient management on cowpea under conservation agriculture, an experiment was conducted during the pre-Kharif seasons of 2013 and 2014 within a rice-wheat cropping system. The study employed a Factorial Randomized Block Design with three replications, evaluating different fertility levels through the application of inorganic sources, organic sources and biofertilizers. Observation on various parameters viz. growth, yield, quality and uptake of major nutrients under inorganic sources has led to the undisputed conclusion that treatment I3 (150 % RDF) was superior to the other two levels of inorganic sources (i.e., 50 % RDF and 100 % Recommended Dose of Fertilizer). All growth, yield and quality traits were observed to be highest in O5 (vermicompost @ 5 t/ha + PSB @ 10 g/kg of seed + Rhizobium @ 10 g/kg of seeds) however, regarding the uptake of NPK, it was peerless under organic sources of treatment O6 (FYM @ 7.5 t/ha + vermicompost @2.5 t/ha + PSB @10 g/kg of seed + Rhizobium @ 10 g/kg of seeds). Eventually as the economics cultivation of cowpea the treatment combination of 150 % RDF + FYM @ 15 t/ha + PSB @ 10 g/kg of seed + Rhizobium @ 10 g/kg of seeds (I3O4) (B: C ratio 3.04) followed by 150 % RDF + vermicompost @2.5 t/ha+ PSB @10 g /kg of seed + Rhizobium @ 10 g /kg of seeds (I3O6) (B: C ratio 2.77) could be well-suited for the terai region of West Bengal.
