摘要

State-level usual planting and harvesting dates for major field crops appear in this report. In addition, dot maps show major areas of production based on 2007 Census of Agriculture data. The information was assembled by the National Agricultural Statistics Service, based on the best and latest information available. The same data for vegetables may be found in 'Usual Planting and Harvesting Dates for Fresh Market and Processing Vegetables', Agriculture Handbook Number 507, issued May 2007. The dates shown indicate the periods in which the crops are planted and harvested in most years based on 20 years of historical crop progress estimates, as well as the knowledge of industry specialists. Beginning dates indicate when planting or harvesting is about 5 percent complete and ending dates when operations are about 95 percent complete. The 'most active' range indicates when between 15 and 85 percent of the crop is planted or harvested. The 'usual planting dates' are the times when crops are usually planted in the fields. For transplanted crops, such as tobacco, the planting period refers to the time of setting plants in the field. The 'harvest dates' refer to the periods during which harvest of the crop actually occurs. Dates do not extend through the subsequent period in which some commodities are stored in the field after harvest.
