Groundnut crop was largely grown under rain-fed condition and are more prone to biotic and a-biotic stresses. TMV 7 was grown by majority of the sample farmers. The average yield of groundnut was 1486, and 685 Kg/ha during kharif 2015 and 2016, respectively. The yield gap –I was -386 kg/ha and 415 kg/ha during kharif 2015 and 2016, respectively. In terms of ratio it was -0.35 and 0.38 respectively during the same period. The yield gap-II was 1108 kg/ha and 1168 kg/ha in Kharif 2015 and 2016, respectively. Attainable yield gap was 0.43 and 0.63 in Kharif 2015 and 2016, respectively which indicates that yield of groundnut can be increased by 43 to 63 percent. Low and erratic rainfall, labor shortage and high cost of seeds coupled with non-availability of quality seeds of varieties and hybrids were the major constraints faced by groundnut farmers in Tamilnadu.
