The present study was conducted to know the cost of cultivation, different costs and benefit-cost ratio incurred in carrot production in different farm size groups that is marginal, small, medium and large. The research was undertaken in Sikandrabad block of Bulandshahr district of Uttar Pradesh, which was selected purposively on the basis of high production and high number of carrot growers in Sikandrabad block from which 110 growers selected from 7 villages of Sikandrabad block. The cost of cultivation of carrot varied among the size groups. The cost of cultivation incurred in carrot production per hectare was highest in large size growers Rupees 150079.63 and lowest for marginal size growers was Rs. 142277.62. Cost incurred for small and medium size growers was Rs. 144496.84 and 147814.17 per hectare respectively. The cost concepts on different size of farm group per hectare, cost A1 was highest for large size of farms Rs. 115371.03 per hectare followed by medium size farms Rs. 108898.24, small size farms Rs. 103536.13, marginal size farms Rs. 102779.54 per hectare respectively. Cost A2 was highest in large size farms Rs. 137371.03 per hectare and lowest for marginal size farm Rs. 124779.54. Cost B was highest in large size of farm groups Rs. 140677.11 per hectare and lowest in marginal size farms Rs. 127465.47 per hectare. Cost benefit ratio was highest in large size farms 1: 1.81 followed by medium size farms 1: 1.71, small size farms 1:1.69 and lowest in marginal farm size 1: 1.66 respectively. The total yield was highest in large size of farm groups which was 60.5 tonne per hectare and lowest in marginal size of farm groups which was 52.6 tonne per hectare.
