Otimização do padrão de cultivo em áreas irrigadas em função do volume de água disponível.

Abstract

Using two linear programming models, based on the crop production response to water availability, it was verified the effect of five water availability conditions upon the irrigated areas optimization. It was studied a model with fixed water depth and another with alternative depths. It was determined the optimal crop tillage planning to be recommended for the Nilo Coelho Irrigation Project, in Petrolina-PE. For both models, it was verified that the financial returns increase as the water availability increases, but the increment in the income decrease. Independent on the model, the total area cultivated increase with a higher water availability.
