tailieunhanh - Conservation agriculture: An efficient tool to overcome the drawbacks of conventional agricultural system towards sustainable crop production

Conservation Agriculture (CA) consists of the practical application of three interlinked principles, that is no or minimum tillage, mulching of soil surface and crop species diversification, in conjunction with other complementary agricultural practices of integrated crop production. In India several efforts have been made to develop, refine and disseminate conservation agricultural technologies for the past two decades and have made significant progress even though there are several constraints that affect adoption of CA. | 2020 9 7 1333-1340 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 7 2020 Journal homepage http Review Article https Conservation Agriculture An Efficient Tool to Overcome the Drawbacks of Conventional Agricultural System towards Sustainable Crop Production Saju Adhikary1 Benukar Biswas1 and Anjali Priya2 1 Deparment of Agronomy Bidhan Chandra Krishi Viswavidyalaya 2 Department of Agricultural Chemistry and Soil Science Bidhan Chandra Krishi Viswavidyalaya Bidhan Chandra Krishi Viswavidyalaya Mohanpur Nadia741252 West Bengal India Corresponding author ABSTRACT Conservation Agriculture CA consists of the practical application of three interlinked principles that is no or minimum tillage mulching of soil surface and Keywords crop species diversification in conjunction with other complementary agricultural practices of integrated crop production. In India several efforts have been made to Conservation develop refine and disseminate conservation agricultural technologies for the past agriculture Conventional two decades and have made significant progress even though there are several agriculture constraints that affect adoption of CA. The technologies used in CA benefit the Constraints environment increase crop diversification improve efficient use of resources Resource use save water and nutrients increase yields and provide opportunity to reduce the efficiency Tillage cost of production. However there are several constraints for promotion of CA Article Info technologies such as lack of appropriate seeders especially for small and medium farmers unavailability of skilled and scientific manpower burning of crop Accepted residues competition of crop residues between their usage in CA and livestock 11 June 2020 Available Online feeding and overcoming the biased mindset about tillage.
