Impact of NPK, Rhizobium and FYM on Physico-Chemical Properties of Soil for Cluster Bean (Cyamopsis tetragonoloba L.) Cv. Radha SPL

An experiment was conducted to study the impact of NPK, Rhizobium and FYM on Soil properties, and Yield of Cluster Bean (Cyamopsis tetragonoloba L.) Cv. Radha SPL at Research farm of Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, during kharif season of 2023-24. The experiment with 18 treatments, was laid out in randomized block design with three replications. The pre and post-harvest soil samples taken for analysis revealed sandy loam in texture. and treatment T18 - [ N20P40K40+ FYM@ 5 t ha-1+Rhizobium@ 600 g ha-1] showed a slight decrease in soil pH (7.18), Db (1.21 Mg.m-1) and Dp (2.20 Mg.m-1) along with increase in EC, pore space, water holding capacity and organic carbon i.e.,0.29 dSm-1, 46.88%, 44.90%, 0.55% respectively. The maximum available nitrogen 292 kg ha-1, phosphorus 31.18kg ha-1 and potassium 264 kg ha-1 were recorded in T18. made it best treatment among soil health parameters.
