Economic and productive analysis of irrigated rice crops using a multicase study

Abstract: The objective of this work was to evaluate the relationship between grain yield and production costs flood-irrigated rice (Oryza sativa) in state Rio Grande do Sul, Brazil, order determine range that maximizes profit farmers. There are estimations pointing out for farmers is about 75 85% potential; however, still needs be validated irrigated Brazil. To validate these values, a technical economic monitoring carried eight rice, whose were measured compared with mean percentage potential achieved. each crop, SimulArroz, process-based model developed simulation growth South used. achieved by ranged from 6.3 11.0 Mg ha-1 (48 83% yield), R$4,197.00 R$6,227.00 ha-1, R$-52.00 R$3,599.00 ha-1. Farmers who reach 69 achieve highest profitability. investment planning based on calculated SimulArroz can efficiently adopted crops.
