Effect of organic sources on growth, yield attributes and yield of summer clusterbean (Cyamopsis tetragonoloba L.) under organic farming

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 “Effect of organic sources on growth, yield attributes and yield of summer clusterbean under organic farming”. The experiment comprised of nine treatments viz. T1: 5.0 t/ha FYM, T2: 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, T9: 2.5 t/ha FYM + 0.5 t/ha castor cake + Rhizobium + PSB were evaluated in randomized block design replicating three times. Significantly higher plant height at 60 DAS and at harvest, Number of nodules per plant and dry weight of nodules per plant, number of pods per plant, seed yield per plant and seed index were recorded under treatment T9 Which was found at par with T6. In the case of Plant population at 30 DAS and at harvest, plant height at 30 DAS, Days to 50% flowering, Pod length, Number of seeds per pod treatments did not affected significantly. Significantly, higher seed yield (901 kg/ha) and stover yield (2709 kg/ha) were achieved with application of 2.5 t/ha FYM + 0.5 t/ha castor cake + Rhizobium + PSB (T9) which remained at par with treatment T6.
