Introduction

Developing countries account for over 97.6% of world groundnut area (21.7 m ha) and about 95.5% of total production (33.0 mt) with average yield of 1522 kg ha-1. Production is concentrated in Asia and Africa, where the crop is grown mostly by smallholder farmers under rain-fed conditions with limited inputs.

Groundnut is an annual legume. Its seeds are a rich source of edible oil (43-55%) and protein (25-28%). About two thirds of world production is crushed for oil and the remaining one third is consumed as food. Its cake is used as feed or for making other food products and halums provide quality fodder.
