Abstract
The field experiment was conducted at central research farm Soil Science and Agricultural Chemistry, SHUATS Prayagraj, (U.P.) on sandy loam soil to see response of Integrated nutrient management on soil properties of green gram (Vigna radiata L.) var. Samrat during Zaid season of 2022. There are nine treatment combinations were comprised in randomized block design with three replications. The soil samples were taken in two depth (0-15 cm & 15-30 cm) for analysis. The results showed that the application of NPK, Vermicompost and neem cake had a significant and non-significant effect on soil physico-chemical properties. The maximum bulk density 1.53 and 1.52 Mg-3, particle density 2.60 Mg m-3 and 2.61 Mg m-3, pH (7.33 and 7.35) and EC 0.33 and 0.32 dS m-1 was recorded in T1 (Absolute control) at 0-15 and 15-30 cm depth respectively. Similarly, the maximum percentage pore space 48.82 and 48.16%, water holding capacity 45.20 and 44.75%, percentage organic carbon 0.52 and 0.50%, available nitrogen 286.66 and 285.66 kg ha-1, phosphorus 29.60 and 28.85 kg ha-1 and potassium 192.74 and. 191.87 kg ha-1 was recorded in T9 [100 % NPK + 100 % Vermicompost + 100 % NC].
