Conservation Agriculture (CA) enhances productivity and maintains the environmental safety and ecological sustainability. According to majority of the respondents, inadequate knowledge on CA as a package was perceived to be the major constraint in adoption of CA. Biophysical constraints predominantly included uncertain monsoon and lack of availability of labour. Technological constraints such as non-availability of desired CA technologies and machineries and policy constraints such as lack of priority, promotion and incentives for adoption were also considered as major constraints. Socio-economic constraints like strong belief in ploughing and institutional constraints like lack of market for alternate crops were also considered as major constraints to adoption of CA. | Constraints to adoption of conservation agriculture technologies among the farming community in Tamil Nadu India
