Abstract:

With the benefits of conserving water and soil，conservation tillage has become an important technology for sustainable agriculture. In order to understand farmers perception for conservation tillage during its adoption and extension process in North China Plain, and provide guidance for optimizing this technology, a face\|to\|face questionnaire survey in conservation tillage demonstration area of Henan province was conducted. The results indicated that the majority of farmers had accepted conservation tillage. No\|till with residue retention for maize has been widely adopted in this region. Due to its benefits in saving water and conserving soil, 83% of the farmers had positive attitude towards conservation tillage, while 74% of the total farmers received the technical guidance from the extension department and hoped to have some guidance for conservation tillage from relevant department. The majority of farmers considered the principal limiting factors for adoption of conservation tillage were high amounts of residues, increasing crop diseases and insect pests, and unstable crop yield. Combining farm machinery with agronomic techniques, strengthening government support, selecting superior cultivars, and improving matching technologies, etc. can surely promote the development and extension of conservation tillage.
