Highlights: While mostly dry conditions prevailed across much of the country, a slow moving low pressure system settled in over much of east Texas, the Delta, and the Southeast dumping more than 4 inches of rainfall in numerous locations and hampering harvest and other fieldwork. Temperatures were below normal across much of the Southwest, southern Great Plains, and northern Atlantic Coast. In contrast, above average temperatures allowed for rapid crop development in the northern Great Plains and much of the Corn Belt.

Corn: Nationally, 97 percent of this year's corn acreage was at or beyond the dough stage by week's end, slightly behind last year and the 5-year average. Denting advanced to 80 percent complete, 9 points behind last year and 13 points behind the average. Denting was most active in North Dakota and the Great Lakes States where drier, unseasonably warm weather promoted late-maturing summer crop development. Nine percent of the corn crop matured during the week, leaving progress, at 21 percent, 9 points behind last year and 34 points, or over 2 weeks, behind normal. Crop maturity was behind in all estimating States; however, the most significant delays were evident in Illinois and Indiana, the second and fifth largest corn-producing States.

Overall, 68 percent of the corn crop was rated in good to excellent condition, down slightly from last week but 9 points better than last year.

Soybeans: Leaf drop progressed at a rapid pace during the week, as ideal growing conditions prevailed throughout most of the major soybean-producing States. By September 20, leaves had dropped in 40 percent of the soybean fields, 1 point behind last year and 18 points behind the 5-year average.

Overall, 67 percent of the soybean crop was rated in good to excellent condition, down 1 point from last week but 10 points better than last year.

Winter Wheat: Seeding of the 2010 winter wheat crop advanced 11 points to 24 percent complete by week's end, 4 points ahead of last year but 1 point behind the 5-year average. Mostly dry weather across much of the country west of the Great Plains continued to promote fieldwork, allowing over 20 percent of the winter wheat fields in Colorado, Montana, Nebraska, South Dakota, and Washington to be seeded during the week.

Cotton: Bolls opened in 11 percent of the cotton fields during the week, leaving progress, at 46 percent, 2 points behind last year and 11 points behind the 5-year average. Delays of 40 points or more were evident in Alabama, Arkansas, and Missouri. Producers had harvested 7 percent of the Nation's crop, 2 points behind last year and 4 points behind the average. Harvest was underway in several States, but was most advanced in Arizona. In Texas, the largest cotton-producing State, harvest in the Blacklands and East Texas was delayed due to excessive rainfall. Overall, 50 percent of the cotton crop was rated in good to excellent condition, down slightly from last week but 2 points better than last year.

Sorghum: Acreage at or beyond the coloring stage advanced to 81 percent complete by September 20, three points ahead of last year but 2 points behind the 5-year average. Forty percent of the crop was mature, 2 points behind last year and 9 points, or slightly more than 1 week, behind the average. Despite significant advancement during the week, double-digit delays remained in Illinois, Kansas, Missouri, Nebraska, Oklahoma, and South Dakota. The harvest pace remained steady but slow in all estimating States except Illinois, Nebraska, and New Mexico where harvest had yet to begin. By week's end, 31 percent of the crop was harvested, 2 points behind last year and 4 points behind normal. Overall, 49 percent of the sorghum crop was rated in good to excellent condition, down 1 point from last week and 4 points below last year.

Rice: Producers harvested 5 percent of the Nation's crop during the week, leaving the overall pace on par with last year but 15 points behind normal. The most harvest activity occurred in California, as producers cut mature fields while actively draining late-planted fields in preparation for harvest. Overall, 61 percent of the rice crop was rated in good to excellent condition, down 2 points from last week and 1 point from last year.

Small Grains: Spring wheat producers had harvested 85 percent of their crop, 11 points behind last year and the 5-year average. Harvest in South Dakota and Washington was completed during the week. In Minnesota, Montana, and North Dakota, producers utilized over 6 days suitable for fieldwork to harvest 18, 16, and 21 percent of their acreage during the week, respectively.

Barley producers harvested 8 percent of their acreage during the week, leaving progress, at 91 percent, 3 points behind last year and 6 points behind the 5-year average. Harvest was complete in Washington ahead of last year and on par with the average.

Other Crops: Peanut producers had harvested 4 percent of the Nation's crop by week's end, 2 points behind last year and the 5-year average. In Georgia, the largest peanut-producing State, the harvest pace stalled as wet weather set in toward the end of the week. Overall, 69 percent of the peanut crop was rated in good to excellent condition, down 1 point from last week but
3 points better than last year.

Producers had harvested 6 percent of their sugarbeet crop by September 20, one point ahead of last year but on par with the 5-year average. Harvest was equal to or ahead of the normal in all estimating States.
