Wheat is a type of grass grown all over the world for its highly nutritious and useful grain. It is one of the top three most produced crops in the world, along with corn and rice. Wheat has been cultivated for over 10,000 years and probably originates in the Fertile Crescent, along with other staple crops. A wide range of products are made from it by humans, including most famously flour, which is made from the grain itself.

Today, wheat is a grass that grows between 2 and 4 feet (0.6 to 1.2 meters) tall. The physical appearance of the grain is familiar to most consumers, with a long stalk that terminates in a tightly formed cluster of plump kernels enclosed by a beard of bristly spikes. The plant is an annual, which means that at the end of each year, fields must be plowed and prepared again to grow the grass.

Ancestral wheats probably looked very different, with much smaller kernels. The early domesticators obviously wanted to select for plants with particularly large kernels, since more nutrition could be eked out from each stalk. Because wheat is generally a self pollinating plant, each plant tends to produce clones of itself. When farmers want to hybridize a strain, they must physically pollinate the different plants. Farmers blending wheat for various purposes usually combine different seeds at harvest time and spread them evenly over the field.

The crops grown in the United States fall into two categories: winter wheat, which is planted in the fall and matures in the summer, and spring wheat, which is planted after the danger of frost is over and also matures in the summer. The plant's characteristic golden color at harvest time is well known and often appears in artwork.

When wheat is ready for harvest, the heads of the grain start to bend the stalks with the weight of the kernels. This, in combination with the golden color, indicates that it is ready. After harvest, the grain is separated from the stalks and chaff. The stalks are used in a variety of applications: mulch, construction material, and animal bedding, for example. On organic farms, livestock are often turned loose on the field after harvest to clean up the leftovers.

Once the kernels have been separated, they can be ground into flour. There are many classifications for flour, depending on what part of the seed is used and how hard the endosperm, the largest part of the kernel, is. The kernels have three parts: the small germ, the large endosperm, and the rough outer casing known as the bran. Hard wheats are suitable for making pasta and bread, and soft wheats are used for other products that do not require a high gluten content.

If a flour is made solely from the endosperm, it is known as white flour. If the germ is ground as well, the product is called germ flour. Flour that uses the whole kernel is called whole wheat. When making flour that doesn't use the whole kernel, the bran and germ are processed and sold separately.

After harvest, the field is cleared and prepared for planting again. Farmers using good rotation practices do not plant it in sequential years, although they may return to the field later.

Why do the USDA and FDA push wheat products even though it is common knowledge that gliadin within the gluten protein causes dozens of autoimmune disorders including skin problems, autism, heart disease, alzheimer's, and cancer? It is also known that the lecithins in wheat cause Crohn's and colitis. The sugar in wheat causes diabetes. The exorphin component of gliadin makes it addictive.

All one needs to do is check the nearly 300 references in the book "Wheat Belly" by cardiologist William Davis. Prove it to yourself. Wheat is poison.

Washington state, particularly where I live in Whitman county, is number 6 in wheat production, but number 1 for wheat production yield per acre. The Northwest is the primary white wheat producer in the United States.

Washington, Oregon, Idaho produced 86 percent of U.S. white wheat in 2008 and continue to keep that lead.

I am a Kansas farmer and I will try to answer some of the questions.

Wheat is a cereal grain. The seeds are harvested and used ground into flour for baking breads.

The major wheat producing states are Kansas, Texas, and the Dakotas. Kansas is the leading state with Texas and South Dakota flip flopping depending on rainfall, or lack of it.

Winter wheat needs to be seeded early enough in the fall that it has adequate time to develop roots and tiller, tillering is developing additional shoots from the main one. But not too early that it has a too much growth, unless it is to be grazed by cattle during the late fall and early spring.

Wheat has a very high nutrient demand. Corn might get criticized for a high nitrogen per acre use, but corn requires 0.8 units of nitrogen per bushel while wheat requirements are over 2 units per bushel. Whenever someone tells about the per acre nitrogen needs of a certain crop always find what the input to output is. Researchers are finding zinc and sulfur deficiencies in wheat the past few years.

Legumes, beans and clovers have exorbitant nitrogen requirements, but they are able to extract nitrates from the atmosphere and convert them to nitrogen, if the correct bacteria is present in the soil.

Durum wheat is the kind of wheat that is used to make pasta. Spring varieties are primarily raised in the northern plains, Montana and Alberta, Canada. Some winter varieties are raised in the Central Valley of California.

Soft wheat is raised in the higher rainfall areas typical of corn belt states: Illinois, Indiana, Ohio, etc.

Wheat will grow in areas with rainfall as low as 15 inches. Generally wheat fields in these arid areas will not a have a crop for a full year before the wheat.

Straw is the stalk, and after harvest some farmers will bale it and use it as livestock bedding or sell it for people to use to mulch garden plants.

The kernel is the grain or the seed that the plant produces.
