Abstract:
A field experiment was conducted during summer season of the year 2018 on loamy sand soil at College Agronomy Farm, B. A. College of Agriculture, Anand Agricultural University, Anand to evaluate the effect of chemical fertilizer, organic manure (Castor cake, Vermicompost and FYM) and bio-fertilizers (Rhizobium and PSB) on nutrient content, nutrient uptake and quality of summer cowpea (Vigna unguiculata L. Walp). Significantly higher nitrogen and phosphorus content and uptake by seed was recorded under treatment T₂ (RDF 20-40-00 NPK kg ha^-1). Whereas, highest potassium content and uptake by seeds was registered under treatment T₈ (FYM @ 4 t ha^-1 + PSB @ 5 mL kg^-1 seed). Significantly higher nitrogen and phosphorus content and uptake in haulm also recorded under treatment T₂ (RDF 20-40-00 NPK kg ha^-1). Moreover, higher content of potassium in seed and haulm was noted with treatment T₈ (FYM @ 4 t ha^-1 + PSB @ 5 mL kg^-1). Significantly higher protein content was recorded under the treatment T₂ (RDF 20-40-00 NPK kg ha^-1). The application of FYM @ 4 t ha^-1 +PSB @ 5 mL kg^-1 seed i.e. treatment T₈ remained at par with the treatment T₂ (RDF) with 22.30% protein content.
