Abstract:
An experiment was conducted during Zaid season (May-July) 2021 to study the “Response of Integrated Nutrient Management on Soil Properties, Growth and Yield of Cluster Bean (Cyamopsis tetragonoloba L.) Var. Deepti” on crop research farm department of Soil Science & Agricultural chemistry. The experiment was laid out in Randomized Block Design having three levels of NPK @ 0%, 50%, 100%, three levels of FYM @ 0%, 50%, 100% and three levels of Vermicompost @ 0%, 50% and 100% respectively. The treatment combinations were replicated three times and allocated at random in each replication. The result shows that the application of different levels combination of NPK, FYM and Vermicompost increased growth, yield of cluster bean and improved soil chemical properties. However, some parameter of soil physical properties decreased. It was recorded from the application of NPK, FYM and Vermicompost) treatment T₉ [NPK @ 100% + FYM@ 100% + Vermicompost@ 100% ] maximum Bulk density 1.359 Mg m^-3 in 0-15 cm and 1.360 Mg m^-3 in 15-30 cm, Particle density 2.552 Mg m^-3 in 0-15 cm and 2.557 Mg m^-3 in 15-30 cm, % pore space 46.630% in 0-15 cm and 46.656% in 15-30 cm, Water holding Capacity 70.02% in 0-15 cm and 72.56% in 15-30 cm, pH 7.73 in 0-15 cm and 7.71 in 15-30 cm, EC 0.260 dSm^-1 in 0-15cm and 0.230 dSm^-1 in 15-30 cm,% Organic Carbon 0.515% in 0-15 cm and 0.464% in 15-30 cm, Available Nitrogen 289.02 kg ha^-1in 0-15cm and 292.05 in 15-30 cm kg ha^-1, Available Phosphorus 29.06 kg ha^-1 in 0-15 cm and 28.01 kg ha^-1 in 15-30 cm, Available Potassium 161.96 kg ha^-1 in 0-15 cm and 196.10 kg ha^-1 in 15-30 cm. The economy of different treatment concerned, the treatment T₉ provides highest net profit of Rs. 94826.56 with Benefit Cost ratio 2.31:1.
