OBJECTIVE: The objective of this study is to explore some of these necessary conditions for effective use of seasonal climate forecasts maize production systems of the Argentine Pampas.
METHODOLOGY & RESULTS
Simulation of Maize yields and economic profits
Table 2-Gross margin of each managent under different ENSO phases
Figure 1. Conceptual representation of climate influences on land assignment decisions in an idealized farm in the Pampas.
Figure 3. Cumulative probability distributions for simulated gross margins obtained under various combinations of ENSO phase and crop management strategies. Strategies compared are those resulting from managing crops as in neutral scenarios (ignoring climate information), as suggested from the decision map (consensus management, with incorporation of climate information) and applying optimal management in each ENSO phase as resulted from crop simulations.
