Zinc application on growth, yield parameters, yield, quality, nutrient uptake and economics of groundnut

Abstract

Groundnut (Arachis hypogaea L.) an important oilseed crop plays a major role in nutritional and economic aspects due to its higher demand in vegetable oil and confectionery items for human consumption. It is grown in dry and semiarid regions with improper nutrient management practices, lack of organic sources of nutrient supplement and no micronutrient application causes zinc deficiency. Zinc deficiency initially causes mottling and chlorosis in upper leaves finally chlorotic condition of entire leaflet at severe conditions. Zinc has various functions viz., activator of enzymes, biosynthesis, enhancement of plant cell development by auxin production. Growth attributes, yield parameters, nutrient uptake were enhanced resulting in higher assimilation, more nodulation and significantly increasing pod yield, productivity with zinc application in groundnut. A panoramic review was made and presented in this paper from research evidences of different eminent research scientist with zinc application in groundnut.
