Response of Integrated Nutrients on Soil Health and Yield Attributes of Cluster bean (Cyamopsis tetragonoloba L.) cv. Neelam

An experiment was conducted during Zaid season 2022 to study “Response of integrated nutrients on soil health and yield attributes of Cluster bean (Cyamopsis tetragonoloba L.) cv. Neelam” on central Research farm Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj. The design applied was randomized block design consisted nine treatment three @ NPK, Vermicompost and Zinc @ 0, 50 and 100%, respectively. The best treatment was T9 (@ 100% RDF + @ 100% ZnSO4 + Vermicompost @ 10 t ha-1) has effect on physical and chemical property of soil and yield of cluster bean. The data observed in post-harvest soil were significantly increased maximum values of percentage pore space (46.533%), water holding capacity (41.103%), organic carbon (0.56%), Nitrogen (328.32 kg ha-1), Phosphorus (20.270 kg ha-1) and Potassium (234.893 kg ha-1). Plant height at different days 30, 60 and 90 DAS was (23.03, 54.22 and 121.86 cm), No. of leaves per plant at different days 30, 60 and 90 DAS was (29.11, 47.74 and 82.60) Pod length (14.11), number of cluster plant-1 (6.47), number of pods cluster-1 (7.47), number of pods per plant (48.35), number of seed pods (9.76), pod weight (2.35 g). The combination of T9 (@ 100% RDF + @ 100% ZnSO4 + Vermicompost @ 10 t ha-1) showed slight decrease in pH (7.250), bulk density (1.172 Mg m-3) and particle density (2.228 Mg m-3) The maximum cost benefit ratio (C: B) 1:2.67, maximum gross return 750900.00, Rs ha-1 maximum net profit 469604.00 Rs ha-1, and highest yield with 25.03 q ha-1 in T9 (@ 100% RDF+ @ 100% ZnSO4 + Vermicompost @ 10 t ha-1).
