A study on economic impact assessment of tomato var. Kashi Aman using the economic surplus model

ICAR-Indian Institute of Vegetable Research, Varanasi, developed a ‘Kashi Aman’ tomato variety in 2013. Farmers in different parts of the country widely adopt and cultivate this variety. The present study helps in estimating the economic surplus generated as a consequence of research outputs for the development of tomato variety ‘Kashi Aman’. The approximate spread of area under Kashi Aman variety was estimated at 247876.13 ha from 2014-15 to 2021-22, covering 146 districts in 25 states. The economic surplus model’s estimated results showed a producer surplus of Rs. 19.18 crore, consumer surplus of Rs. 30.44 crores and total economic surplus of Rs. 49.62 crores generated from the variety. The Net Present Value (NPV) generated was Rs.48.83 crores and Net Present Benefit (NPB) was Rs.49.62 crores. The Internal Rate of Return (IRR) was 85% and Benefit Cost Ratio (BCR) 62.91 in the present technology. The total cost of cultivation of Kashi Aman variety of tomato was Rs. 194101 per hectare compared to Rs. 211303 per hectare of local variety. The net return in the Kashi Aman variety of tomatoes was Rs. 294149 per hectare while it was Rs. 218697 per hectare in local variety of tomatoes. The BC ratio was 2.52 and 2.04 for Kashi Aman variety and local variety of tomatoes grown by the farmers. The present study indicates that the investments made for the development of Kashi Aman variety of tomato was highly economical and provided evidence to the policymakers supporting the research investment.
