  winter wheat
Unusually mild winter temperatures caused China's 2007/08 winter wheat and rapeseed crops to emerge from dormancy well ahead of schedule and grow abnormally fast, weakening their resistance to extreme weather.
The wheat crop was in the jointing to flowering stage as of April 20.
As of April 30, the winter wheat crop was in the boot/flowering stage on the North China Plain and in the flowering/grain fill stage in the Yangtze River basin.

 Irrigation of Winter Wheat
Winter wheat is predominantly a dryland crop in Colorado, but the importance of irrigated winter wheat has increased as farmers become concerned about reducing the costs of pumping water for production of other Crops.
Winter wheat responds to supplemental irrigation, but careful irrigation management is important to produce consistently high yields with minimum costs.
Winter wheat irrigated with a sprinkler system can be fertilized more efficiently by injecting liquid fertilizer through the system.

 Wheat Streak Mosaic
Infection of winter wheat may occur in the fall if volunteer wheat, spring wheat, grassy weed hosts or corn plants infected with the virus and infested with mites are still green at seedling emergence of winter wheat (Figure 4).
Infection of spring wheat depends on winter survival of the mite on winter wheat, volunteer winter wheat, or perennial grasses and on buildup of the mite population in the spring (Figure 4).
Spring Wheat: Avoid late planting of spring wheat near winter wheat that is maturing, as virus-bearing mites are likely to be wind-blown to the spring wheat while it is still young and especially vulnerable.

 Teagasc - Project Report - 4316 - Bi-Cropping of Winter Wheat and White Clover
While the results indicate that winter wheat can be successfully established in an understorey of white clover if sown early in good conditions, competition from grass weed species represents a serious impediment to successful bi-cropping in the longer term.
Winter wheat (Hereward) was sown into the clover plots with a Hunter Rotaseeder drill at a seeding rate of 200 kg/ha, 22.8 cm row spacing and in the conventional plots at 200 kg/ha, 12 cm row spacing.
Wheat yields should eventually increase in the bi-cropped area due to the supply of legume fixed nitrogen based on the fertility of clover containing pasture swards (Cowling, 1982; Clement and Williams, 1967).

 ERS/USDA Briefing Room - Wheat: Background
Wheat varieties grown in the United States are classified as "winter wheat" or "spring wheat," depending on the season each is planted.
Wheat milling byproducts—such as bran (outer seed coat of a wheat kernel), shorts (more inward layers of the seed coat that contain some starchy or floury components), and middlings (an intermediate fraction that consists of a combination of bran and shorts)—are used by feed manufacturers in the production of animal feeds.
Loss of wheat acreage to row crops on the Plains reflects strong genetic improvements in corn and soybeans, producing varieties that could be planted farther west and north in the region, areas with drier conditions or shorter growing seasons.

 Six Basic Classes of Wheat   (Site not responding. Last check: )
Wheat is the principal U.S. cereal grain for export and domestic consumption.
Winter wheat, which normally accounts for 70 to 80 percent of U.S. production, is sown in the fall and harvested in the spring or summer; spring wheat is planted in the spring and harvested in late summer or early fall.
Wheat classes are determined not only by the time of year they are planted and harvested, but also by their hardness, color and the shape of their kernels.

Wheat is used to produce flour (for bread, pasta, pastries and macaroni) or livestock feed.
As the wheat plant dries down, wheat curl mites congregate on green tissue in the upper parts of the plants where they are picked up by wind currents and carried to their summer grass hosts.
Following seeding, as the young wheat sprout grows from the seed to the surface of the soil, spores on the seed or in the soil germinate in response to moisture and form slender infection threads (mycelium) that enter the seedling.

 Guide to Wheat Diseases and Pests
Symptoms: The pericarps of maturing wheat kernels turn dark brown to fl, with the discoloration usually restructed to the germ-end of the kernel (33; 34 is healthy seed).
Hosts/Distribution: Wheat, triticale, rye, oats, and other related grasses can be affected by the disease, with wheat being the most susceptible; winter wheat and fall-sown spring wheat are more frequently damaged.
Wheat lines having solid or partially solid stems are much less susceptible to attack.
