Abstract

                                Field experiment conducted with groundnut var. CO 2 to evaluate the efficacy of micronutrient chelates on the yield, yield attributes, micronutrient availability and their uptake by the crop revealed that, the soil application of either FeSO4 or ZnSO4 influenced the yield attributes in early stages while at later stages, the foliar spray of chelated micronutrient mixture @ 0.5% registered the highest values. With regard to micronutrient availability and their uptake. foliar spray of chelated mixtures increased the respective micronutrient concentrations besides their uptake.

Key words : Yield, yield attributes, chelated micronutrients, DTPA micronutrients, content, uptake
