This study analyzes the farmers' buying behaviour with reference to hybrid vegetable seeds. The research was carried out in the major six vegetable growing blocks of Coimbatore District, Tamil Nadu. A total of 120 farmers were selected using the simple random sampling method. The major Hybrid vegetables grown in the study area were tomato, gourds, bhendi, chilli and brinjal. Yield, price, quality, pest and disease resistance were the major factors influencing the farmers’ buying behaviour of vegetable seeds. Pest and disease attacks and high seed prices were the significant problems that the sample farmers were facing when cultivating hybrid vegetables. Field demonstrations and free samples to vegetable growers were the two most common promotional activities used by hybrid vegetable seed companies.
