Abstract

Among oilseed crops, groundnut is an important edible oilseed crop of our country and edible oil economy primarily depends upon groundnut production. Calcium, magnesium and sulphur requirements are highest in oil seed crops followed by pulses and least in cereals. Secondary and micronutrient fertilization is essential for enhancing the productivity of groundnut crop. The response of groundnut to secondary and micronutrients was studied on sandy loam soils of Agricultural College Farm, Mahanandi, Andhra Pradesh during rabi 2015. The experiment comprised 10 treatments consisting of recommended dose of NPK through soil application and foliar application of secondary and micronutrients. Combined foliar application of secondary and micronutrients along with RDF recorded significantly highest pod yield of 2654 kg/ha and haulm yield of 3603 kg/ha as compared to RDF (1500 and 2551 kg/ha 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 use of all the nutrients.
