These data are in turn used to evaluate global supply and use estimates. The evaluation of a crop's yield response is based upon the cumulative effects of weather during crop development. The crop's response to anomalous weather is a function of crop type and growth stages. This reference handbook provides the framework for assessing the weather s impact on world crop production by providing the latest available information on climate and crop data for key producing regions and countries. Coverage includes major agricultural regions and crops, including coarse grains, winter and spring wheat, rice major oilseeds, sugar, and cotton.
World maps show the normal developmental stage of regional crops by month.
