Abstract

Sugarcane is a crop of major social, economic and environmental importance for Brazil. In order to meet the increasing demand for sugar and ethanol, sugarcane areas have been expanding strongly over the last decade reaching areas with adverse soil and climatic conditions. The analysis of sugarcane production in these marginal areas for decision support and planning is possible using dynamic process based crop models. This project aims to couple a sugarcane process-based crop model with the soil water balance provided by SWAP model, and improve the canopy processes simulation by using a plant architecture approach. Several experimental data of sugarcane growing and developing will support the model calibration and evaluation of model performance. This approach is expected to improve the simulation of soil components for sugarcane crop leading to more detailed yield predictions.
