With 19 per cent of world's area and 10 % of world's production India is one of the oilseed producing countries in the world. In the domestic agricultural sectors, oilseeds occupy a distinct position after cereals sharing 14 % of the country's gross cropped area and accounting for nearly 6 % of the gross national product and 10 % of the value of all agricultural products. India accounts for 9.6 % of the world's total output of oilseeds. With more than 25 million hectares of land under oilseeds the world's largest area under oilseeds. However, at present the average yield of oilseed is only 900 kg as against world average of 1275 kg and a yield of 2500kg/ha in USA. Gujarat accounts for one third of the country’s groundnut production. About 75 per cent of this production is confined to Saurashtra region of the state characterized by rainfed farming with high risk and low yield. The results of the present study will provide the information about the yield gap in groundnut production...
