This zone covers about 80 percent of the total area of cotton in the state. The study focused on the efficiency of resource use. Two villages namely 4C and Mirjawala were selected from Sri ganganagar tehsil of the zone. Sixty farmers were selected at random in proportion to the total number of farmers in each size group from the list of Bt cotton farmers group and similarly another 60 farmers were selected from American cotton farmers group. The Cobb Douglas production function, revealed that the Bt cotton farmers were underutilized seed and human labour inputs, where as American cotton farmers were underutilized fertilizer. Key word: MVP/MFC, Resource use efficiency, Bt. cotton, American cotton. INTRODUCTION bales, in 2011-2012 area was 121.78 lakh India ranks first in cotton area in the world and hectares and production was 353.00 lakh bales third in production. About 15 million farmers and in 2012-2013 area was 119.78 lakh in the country spread across 10 states are hectares and production was 365.00 lakh bales. engaged in cotton production. Cotton is grown Area under cotton in Rajasthan (2010-11) was in about 10 million hectares in India and is 3.35 lakh hectares and production was 10.10 cultivated in three distinct agro-ecological lakh bales, area was (2011-2012) 4.70 lakh regions viz., North, Central and South. Out of hectares and production was 18.00 lakh bales total, 21 per cent area is under cultivation in and in 2012-2013 area was 4.50 lakh hectares North zone which is 100 per cent irrigated and and production was 17.00 lakh bales (bales of contributes 25 per cent of the production. 170 kg) 1. The major cotton producing states in About 80% of the total cotton area of the country are Maharashtra, Gujarat, Andhra the entire state of Rajasthan is being grown in Pradesh, Punjab and Tamil Nadu. In India Irrigated North Western Plain zone Ib. This 2010-11, the area under cotton was 111.42 zone covers Sriganganagar and Hanumangarh lakh hectares and production was 339.00 lakh districts of Rajasthan.

Amongst all previous year 2012-13. The farmers who did the pests which attack cotton in India, not grow cotton were deleted from the list. The bollworms namely, American bollworm farmers from the list were divided into two (Helicoverpa armigera), spotted bollworm groups (i) Bt. cotton farmers and (ii) American (Earias insulana and Earias vitella) and pink cotton farmers. The farmers of each group bollworm (Pectinophora gossipiella) cause were divided into following three size groups. major damage.
