Abstract: Among the nine oilseed crops, groundnut is an important edible oilseed crop of our country and edible oil economy primarily depends upon groundnut production. Zn deficiency in Indian soils is likely to increase from 49 to 63% by 2025. India is leading in groundnut acreage but behind the China in production due to less productivity. Apart from rain dependent cultivation and mineral nutrition play a vital role in groundnut productivity. Among the nutrients, Zn deficiency cause yield loss to the maximum of 40% in groundnut. The average response of groundnut to zinc fertilization ranged from 210 to 470 kg ha-1. Hence, it is ideal to follow suitable crop improvement and agronomic management strategies to enhance the uptake and availability of Zn in peanut. Keeping in view the above facts, the present review reveals the effect of zinc on growth, yield, nutrient uptake and quality of groundnut.
