Biofuels from soybean and corn oil can potentially create new markets in Brazil. The key to a stable biofuel production is the use of high-yielding varieties tolerant to environmental stresses. The inter-annual variability of rainfall caused by large scale
meteorological phenomena, such as El Nino-Southern Oscillation and irregular distribution of precipitation has been a major cause of uncertainty in agricultural production in Brazil. The objective of this study was to perform an inter-annual and inter-regional analysis of soybean and corn yield in relation to water deficit in a transitional zone between subtropical and tropical climate in southern Brazil. The study was conducted in the state of Parana (22?26º S), one of the main soybean and corn producing areas in the country. The state was divided into six regions (Northwest, North, West, Midwest, Southwest, and South), and the year with the highest productivity in each region was used as a reference to calculate the relative yield losses per year. These losses were correlated with the accumulated water deficit between November and January. The relative yield losses of soybean and corn had a nonlinear relationship with water deficit within each region. Based on the market prices of each year, we estimated that the total losses due to water deficit over the nine growing seasons were $8.36 and $2.67 billion for soybean and corn, respectively. In terms of productivity, the South region showed the highest stability, whereas the Northwest region the lowest stability in response to water deficit. The results show that inter-annual and regional variability of water stress play an important role in soybean and corn productivity in the transition zone between tropical and subtropical climate in southern Brazil.
