Abstract:

The vegetable production in India is largely produced by small and marginal farmers from small scale subsistence level farming systems. Even at the time of producing the crops and at the time of selling them, they face a lot of hurdles and obstacles. Keeping this in view the study focus on the real factors responsible for the less productivity in vegetable crops and to give suitable measures. The research was conducted in Madurai district of Tamil Nadu, India with 90 respondents. Interview schedule was used for collecting data. Fruit borer (70.00 %), blossom dropping and less fruit setting percentage (68.33%), sunscald (61.66 %), tomato cracking or split tomato problem (53.33%), yellow or green tomato shoulders and deformation of tomato fruit (51.66%) were the major biological factors for yield gap. With regard to brinjal the major problems are fruit and shoot borer (76.66%), fruit rot /blossom end rot (40.00%), brown streaking (36.66%) and small size and unsized hard fruits (30.00%). With regard to bhendi the major problems are fruit borer and powdery mildew (50.00%).  Bhendi curling/small size of fruit/discoloration and hardness (40.00%) was expressed by the farmers which reduce the yield. Rise in fertilizer and pesticide prices, unavailability of timely and quality inputs, lack of knowledge to identify pest and diseases, lack of communication and training cum demonstrations on improved practices were felt by 35-45 percent of the farmers as other factors for yield gap. Support of research and extension is necessary for narrowing the yield gap.
