Effect of Integrated Use of Fertilizer P, Pressmud and Psm on N, P, K and S Content and Uptake by Summer Groundnut under Gujarat Condition

In order to confirm the efficiency of intigration of inorganic fertilizer with pressmud and psm for yield, nutrient content and uptake of groundnut, the field experiments were conducted for two years on college research farm at, Navsari. The results indicated clearly that pod, haulm, karnal and shell yields of groundnut were significantly higher under optimum dose of 15 kg P from SSP (inorganic) + 5 t pressmud (organic) + 2.5 kg PSM (biofertilizer) ha^-l. In gernal, the higher N, P and S content in Kernal was found as compared to haulm and shell. The higher N and K content in haulm were found as compaired to shell, where as P and S content in shell were higher than haulm during both the years. The higher N, P, K and S content and uptake were recorded by optimum dose of 15 kg P from SSP + 5 t pressmud + 2.5 kg PSM ha dynamics of manganese fractions in the LTFE’s soils.
