Centers of origin refer to geographic regions where a particular crop is believed to have first been domesticated and developed into its present form. Examples include the Fertile Crescent for wheat, the Andes for potatoes, and Central Mexico for maize.
The distribution of fodders and cash crops varies depending on the crop and the region. Fodders, such as alfalfa and clover, are typically grown in areas with a strong agricultural industry and are used to feed livestock. Cash crops, such as cotton and coffee, are grown in regions with favorable climate and soil conditions and are sold for profit.
Vegetable and horticultural crops also have a wide distribution, with different crops being grown in different regions depending on climate and soil conditions. For example, warm-weather crops such as tomatoes and peppers are typically grown in regions with a warm climate, while cool-weather crops such as broccoli and cauliflower are grown in regions with a cooler climate.
