Effect of sulphur and boron on nutrient content and uptake by summer groundnut (Arachis hypogeal L.)

An experiment was conducted during summer of 2016 to study the effect of sulphur and boron application on nutrient content and uptake pattern of N, P, K, S and B in groundnut. The experiment showed that increase in application of sulphur led to an increase in the concentration and in turn uptake of N, P, K, S and B in pods and haulm up to 45 Kg/ha. However, the increase in nutrient concentration and uptake parameters with the increase in sulphur from 30 Kg/ha to 45 Kg/ha showed no significance. Owing to boron application similar trend was followed in N, P, K, S and B concentration and uptake by the crop. However, it was found that higher levels of sulphur and boron showed antagonistic effect on nutrient content and uptake of summer groundnut at pod harvesting stage. The study suggested that soil application of sulphur and boron in clay loam soil in waghai, Dangs increased the availability of primary nutrients in addition to sulphur and boron causing their absorption by summer groundnut.
