Effect of Organic Manures, Biofertilizers and Cow Urine Spray on Growth, Yield and Quality of Clusterbean (Cyamopsis tetragonoloba L.)

Abstract

A field experiment was conducted during the kharif season of the year 2021 at Agronomy Instructional Farm, Department of Agronomy, CPCA, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to evaluate the “Effect of organic manures, biofertilizers and cow urine spray on growth, yield and quality of clusterbean (Cyamopsis tetragonoloba L.)” under loamy sand soil. The experiment was laid out in randomized block design with three replications. Thirteen treatments comprises different organic sources viz., T1: 100% RDF through chemical fertilizers (control), T2: 100% RDN through castor cake (CC), T3: 100% RDN through poultry manure (PM), T4: 100% RDN through neem cake (NC),  T5: 75% RDN through CC + biofertilizers (NPK), T6: 75% RDN through PM + biofertilizers (NPK), T7: 75% RDN through NC + biofertilizers (NPK), T8: 75% RDN through CC + 5% cow urine, T9: 75% RDN through PM + 5% cow urine, T10: 75% RDN through NC + 5% cow urine, T11: 75% RDN through CC + biofertilizers (NPK) + 5% cow urine, T12: 75% RDN through PM + biofertilizers (NPK) + 5% cow urine and T13: 75% RDN through NC + biofertilizers (NPK) + 5% cow urine. The results revealed that an application of 75% RDN through PM + biofertilizers (NPK) + 5% cow urine (T12) recorded significantly higher plant height, number of branches per plant, number of pods per plant, seed index, seed yield, stover yield and crude protein content in seed. However, gum content in seed was recorded significantly higher in treatment T13. Therefore, the application of different organic sources of nutrients treatment application significantly influenced the growth, yield and quality of clusterbean. It is concluded that the combined application of poultry manure, biofertilizers and cow urine spray (T12) can be obtained maximum seed and stover yield with better seed quality.
