What is Assessing yield and economic impact of introducing soybean to the lowland rice system in southern Brazil about?

Lowland irrigated rice in southern Brazil is typically grown in monoculture, with one rice crop per year. However, during the past 10 years, some farmers have switched from the traditional continuous rice system to a 2-y soybean-rice rotation. Here we performed an on-farm assessment about the impact of introducing soybean to the lowland continuous rice system in southern Brazil. The goal was to determine how the soybean-rice rotation compared to continuous rice in terms of yield and profit. We used farmer-reported survey data collected from lowland rice-based systems in southern Brazil over three growing seasons. Cropping-system yield, profit, and return-to-inputs were compared between fields following continuous rice versus soybean-rice rotation. In addition to the survey data analysis, we evaluated the long-term economic impact of adopting the rotation using a combination of a crop simulation model and Monte-Carlo stochastic modeling. Average rice yield was 26% higher in the rotation compared to continuous rice. Besides the rotation effect, sowing date, N fertilizer, and weed management explained most of the field-to-field variability in rice yield. Cropping-system yield and gros
