Study on constraints faced by farmers in adoption of green technologiesin rice based ecosystem

The current study was carried out in Madurai and Trichy districts of Tamil Nadu. Two blocks from each district were chosen. The various constraints faced by farmers in adoption of green technologies in rice based ecosystem was measured by using Garret ranking technique. For this study, a total sample size of 240 people was used. It was observed that labour scarcity was ranked as first followed by poor quality of inputs as second and lack of advanced planning about the purchase and application of manures and fertilizers as third. Farmers had lack of knowledge in identifying pests and diseases and applied extra doses of fertilizers which inturn cause harm to themselves as well as to the crops.
