Abstract
Conservation agriculture, based on direct seeding, offers an ecological production method based on an integrated and sustainable management of mulch and soil resources. The techno-economic and environmental impacts of this production alternative are variable depending on the production system and the agroecological zone. This work aims to assess different impacts of conservation agriculture compared to conventional agriculture, using a set of agronomic, economic and environmental indicators at the scale of an experimental station. The experimental device combines a set of crop rotations, in rainfall and irrigated system under conventional and conservation agriculture. The analytical methodological framework used the tools of descriptive statistics and multidimensional analysis, including principal component analysis (PCA). Results show the added value of conservation agriculture, which has higher economic and agronomic performance and positive environmental benefits.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
