Abstract

The agricultural production systems, increasingly more sustainable strategies are adopted. Systems that perform rotations with soybeans and rice, may have technical, economic and environmental benefits for farmers, because unlike soy to be a distinct species of rice ensures through a merged system of cultivation, breaking dominance of weeds, especially the red rice. Due to increasing growth of soybean cultivation in flood plains in the state of Rio Grande do Sul, the objective of this work was to make a diagnosis of the use of rotation soy/rice crop in the lowland areas in the municipality of São Gabriel (RS). First we carried out a bibliographical survey of rice, soybeans and environmental benefits of crop rotation of rice/soybean. Subsequently, we applied a questionnaire directed to farmers where we sought information on crop development in rural properties and its positive and negative aspects related to environment and sustainable development, it was concluded that soybean cultivation in places floodplain, enables control of weeds ervar, higher income and also reduces production costs. Therefore represents a more sustainable alternative in the economic, technical and environmental aspects.
