Effect of integrated nutrient management on growth and yield of pigeon pea (Cajanus cajan) in changing climatic condition of Bihar

A field experimental was conducted at Krishi Vigyan Kendra, Khodawandpur as well as Gadhpura and Barauni blocks of Begusarai district to study the effect of integrated nutrient management for sustaining the productivity of pigeon pea [Cajanus cajan (L.) mill sp.] under rainfed conditions. Growth and yield attributing characters viz., plant height, yield induced such as days to 50% flowering, branches/plant, leaf area, pods/plant, pod length, number of grains/pod, 100 seed weight, grain and stalk yield and benefit-cost ratio were significantly higher at recommended dose of fertilizer (RDF) than organic manure and bio fertilizer. Application of RDF with vermi compost @ 2 tones/ha, Farm Yard Manure (FYM) @ 5.0 tones/ha and bio-fertilizer singly and combined enhanced the yield attributes grain yield parameters. Seed inoculation with Rhizobium + phosphate solubilizing bacteria (PSB) alone or combined inoculation were found effective and significantly enhanced the yield attributing and grain and stalk yield of pigeon pea.
