• Resumen

  • 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.
