One of 40 new maps showing major crop-producing areas in the United States and other nations.
A total of 40 new maps have been prepared, showing major crop-producing areas in the United States, China, India, Pakistan, and South Africa. Earlier versions of these maps appeared in the Major World Crop Areas and Climatic Profiles (MWCACP) handbook that contains climatological data, agricultural statistics, and crop calendar information for major agricultural areas worldwide, and serves as a reference for evaluating the effects of weather on world crop production. The new maps, listed by country and commodity, supplement the MWCACP publication by updating illustrations of cropping patterns in these countries: Read more »
Researchers in Njoro, Kenya, evaluating wheat for resistance to Ug99 in October 2005.
The Journal Nature today published a paper reporting that scientists from USDA’s Agricultural Research Service (ARS), as part of an international team, have completed a shotgun sequencing of the wheat genome. The achievement is expected to increase wheat yields, help feed the world and speed up development of wheat varieties with enhanced nutritional value. Wheat is one of the world’s “big three” crops, along with rice and corn, upon which the world’s growing population depends for nutrition.
Sequencing the genome of wheat was unusually daunting because the wheat genome is five times the size of the human genome, and has 94,000 to 96,000 genes. This sequencing effort involved the identification of essentially all of those genes and mapping their relationship to other genes. Previously, the size and complexity of the wheat genome had been significant barriers to performing a complete analysis, but the scientists overcame that problem by developing a new strategy that compared wheat genetic sequences to known grass genes, such as from rice and barley.

During the last week, much-needed rain developed across the northern and eastern Corn Belt and continued in the Southeast, stabilizing or even improving crop and pasture conditions. In the Midwest, some of the heaviest rain (locally 2 to 4 inches) fell from southern and eastern Wisconsin into Ohio. Substantial rain (at least 2 inches) also extended into the northern Mid-Atlantic States. Meanwhile, a second consecutive week of widespread Southeastern showers further revived pastures and aided immature summer crops. Weekly totals in excess of 4 inches were noted in the central Gulf Coast region and parts of the interior Southeast. Read more »
