Out of several options of resource conservation technologies, rotavator can improve inputs use efficiency, increase farm income by improving crop yield and protect soil biodiversity and natural resources, etc. The
present study was carried out in Chandauli district to assess the economic and environmental impact of resource conservation technologies. The study was based on primary data which were collected through personal interview. Chandauli district was purposively selected for the present study because large numbers of farmers were using rotavator for wheat cultivation. From the selected village, 30 rotavator adopters and 30 non-adopters were selected using snowball sampling method for primary data collection. Results suggested that after adoption of rotavator, wheat yield and net income from wheat were increased significantly as compared to non-adopters. In case of rotavator adopter, per hectare net income received from wheat production was Rs. 54493.29, whereas in case of non-adopter it was Rs. 33940 and incremental net benefit was Rs. 20553.29 over non-adopters. Per hectare wheat yield was found to be 45 and 37.5 q for rotavator adopters and non-adopters, respectively. The benefit-cost ratio was 2.06 and 1.63 for rotavator adopters and non-adopters respectively. The reduction in use of fossil fuel for land preparation, sowing of wheat crop and running diesel pump for pumping irrigation water lead to reduction in carbon emission. After adoption of rotavator, per hectare carbon emission was reduced by 11.69 kg as compared to nonadopters. It is suggested that government should provide more subsidy on purchase of rotavator and post sell technical support to farmers for large scale adoption of technology. This will not only increase the
wheat grain availability but also reduce the carbon emission.
Key words : Rotavator, CO2 emission, cost of cultivation, environmental benefit, economic benefit
