Conclusions

For rainfed corn production systems in Isabela, Philippines, the recommended planting date for the location can be estimated by determining the historical end of the rainfall occurrence based on available climate data, and deducting from this period about 55 days to avoid water stress during the critical period of the reproductive stage from flowering until the end of grain formation. During wet season cropping, however, the use of advanced climate information to determine the recommended planting date may not be useful and practical as the crop will not experience significant water stress throughout its growing period since there is adequate soil moisture available. This excludes the fact that the wet season is also characterized by atmospheric disturbances due to typhoons with strong winds and heavy rainfall which may destroy the crops.

Field research results have demonstrated that corn farms which used climate information to base the planting date obtained higher crop yields and higher net income compared to areas which were planted based on farmers' decision of planting date. Farms which used advanced climate information-based planting date had a generally higher yield than the average level in the entire village. These results had shown that using advanced climate information in farm-level climate-related decisions in corn production system can lead to increased yield and farm income and can minimize risks due to climate variability.
