Abstract

Groundnut is an important edible oilseed crop of our country and edible oil economy primarily depends upon groundnut production. Secondary and micronutrient fertilization is essential for enhancing the productivity of groundnut crop. Calcium, Magnesium and Sulphur requirements are highest in oil seed crops followed by pulses and least in cereals. The response of groundnut to secondary and micronutrients was studied on sandy loam soils. Combined foliar application of secondary and micronutrients along with RDF recorded significantly highest pod yield of 2654 kg ha-1 and haulm yield of 3603 kg ha-1 as compared to RDF (1500 and 2551 kg ha-1 of pod and haulm yield, respectively) and also the highest uptake of primary nutrients (N, P and K) by haulm and pod at harvest which might be because of highest dry matter production with the combined application of all the nutrients.
