Seed village programmes are becoming popular in developing countries due to their potential to supply of affordable seed to farmers in a timely manner. Under the programme, the profitability of seed growing farmers is important as it incentivizes them to grow more seed for distribution of seed to other farmers. This paper tried to analyze the impact of the seed village programme on profitability of seed growing farmers of paddy crop by using Difference-in-Difference approach. The study was conducted during the year 2020 in India. A significant increase in profitability of seed growing farmers compared to non-seed farmers was noticed due to the SVP scheme. It was observed that after the introduction of SVP, there was about 69.01% increase in profits of seed-farmers compared to only 5.63% among non-seed-farmers. Age, education, acreage under seed production and farming experience contributed 71.6% of the total variation in the higher profits through SVP in paddy crop, leaving the rest to extraneous factors. The difference-in-difference regression results showed that, with the introduction of the SVP in India, there was an increase in the profits of seed growing farmers by INR 13,032/acre (186 USD). These results show that most of the seed growing farmers are in favor of the growing seed under SVP and benefited from this programme.

The front line demonstrations were organised in 30 farmers fields during 2017–2020 in Nagarkurnool district. The IPM strategy included clipping and disposal of infested shoots, removal of fruits with boreholes, installation of pheromone traps @ 25 ha-1, spraying of Bacillus thurinjiensis @ 1 g l-1 and Emamectin benzoate 5% SG @ 0.4 g l-1. The mean of the parameters in 30 demonstrations during three years (pooled) revealed that shoot and fruit borer damage at a vegetative phase as shoot damage was 18.29% in demo field and 29.92% in farmers practice. Fruit damage was recorded low 23.02% in the demo field while in farmer’s practice it was 47.37%. Higher marketable fruit yield was recorded 274 q ha-1 in demo field and 17.6% yield increased over farmers practice (233 q ha-1) with benefit Cost Ratio of 2.97:1 and 2.11:1, respectively. Besides this, number of pesticide sprayings reduced significantly in the demo field (5.2 times) when compared to farmers practice (13.13 times). It is also observed that higher gross returns (` 264700 ha-1) and net returns (` 201806 ha-1) were recorded in the demo field than farmer’s practice (` 264700 and ` 131496, respectively). The technology gap and extension gap enumerated from this study ranged 252-367.5q ha-1 and 28.5-63.81 q ha-1 respectively with the technology index of 54% during demonstration years. The results clearly showed that the positive impact of front-line demonstrations over farmer’s practice towards increasing the productivity and reduce the cost of cultivation of Brinjal in Nagarkurnool dist. of Telangana State.
