Response of NPK and Neem Cake on Soil Properties, Growth and Yield of Cluster Bean

At the soil science and agricultural chemistry research farm, an experiment was carried out during the 2023–2024 growing season. Nine treatments were arranged in a randomised block design with three replications for the current investigations. The pre-sowing soil sample used for the analysis of the cluster bean was taken for the study. The soil has a sandy loam texture, and the cluster bean responds considerably to the various treatment combinations. Under treatment T9 -, the highest phosphorus was measured at 30.43 kg ha-1 in 0–15 cm deep and 27.65 kg ha-1 in 15–30 cm depth. and in treatment T1, the lowest phosphorus levels were 18.81 kg ha-1 at 0–15 cm depth and 15.74 kg ha-1 at 15–30 cm depth. Treatment T9 produced the highest potassium levels, 252.9 kg ha-1 in 0–15 cm depth and 186.7 kg ha-1 in 15–30 cm depth, while treatment T1 produced the lowest potassium levels, 199.7 kg ha-1 in 0–15 cm depth and 166.8 kg ha-1 in 15–30 cm depth.
