Abstract:
A field experiment was conducted during Summer season of 2020 at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, to study the "Influence of different organic sources on quality, uptake, soil microbial population and economics of summer clusterbean (Cyamopsis tetragonoloba L.) under organic farming. The experiment comprised of nine treatments viz. T₁: 5.0 t/ha FYM, T_2: 1.0 t/ha castor cake, T₃: 2.5 t/ha FYM + 0.5 t/ha castor cake, T₄: 5.0 t/ha FYM + NPK consortium, T₅: 1.0 t/ha castor cake + NPK consortium, T₆: 2.5 t/ha FYM + 0.5 t/ha castor cake + NPK consortium, T₇: 5.0 t/ha FYM + Rhizobium + PSB, T₈: 1.0 t/ha castor cake + Rhizobium + PSB, T_9: 2.5 t/ha FYM + 0.5 t/ha castor cake + Rhizobium + PSB were evaluated in randomized block design replicating three times. Significantly higher protein content (26.73%) and protein yield (239.10 kg/ha) recorded over all other treatments. Total uptake of N and P by clusterbean, treatment T₉ (2.5 t/ha FYM + 0.5 t/ha castor cake + Rhizobium + PSB) recorded significantly higher uptake of N and P. Significantly the higher Rhizobium (242.20 CFU × 10⁴/g soil) and PSB (272.88 CFU × 10⁴/g soil) count were recorded in treatment T₉. On an average maximum net realization (₹36463/ha) and benefit: cost ratio (BCR) (2.39) were obtained with treatment T₉ followed by treatment T₆.
