Winter wheat is grown as a cash crop or a cover crop.Optimal growing conditions for winter wheat include high-drainage soil with medium texture. Mid-quality soil nutrient content is best for winter wheat, with an appropriate supply of nitrogen being critical for the wheat to be able to establish itself in time before winter dormancy.
Winter wheat at the end of March. Winter cereals, also called winter grains, fall cereals, fall grains, or autumn-sown grains, are biennial cereal crops sown in the autumn.They germinate before winter comes, may partially grow during mild winters or simply persevere under a sufficiently thick snow cover to continue their life cycle in spring.
In the North American plains, the wheat production axis that extends over a length of 1,500 miles (2,400 km) in a north–south direction from central Alberta to central Texas is known as the Wheat Belt. Hard red winter wheat is grown in the Central U.S. states of Kansas, Nebraska, Colorado, Oklahoma, Missouri, Iowa, Illinois, and Texas and ...
In Southern California, the temperature differences are approximately 4 °F in winter and 23 °F (2 °C and 13 °C) in summer. At the coast in Santa Monica , the average high in August is 75 °F (24 °C), while in Burbank , approximately 10 miles (16 km) inland, the average high in August is 95 °F (35 °C): a temperature gain of about two ...
California's Mediterranean climate supports irrigation events such as nitrification which encourage nitrous oxide production. Mean nitrous oxide emissions (the biggest contributor to ozone depletion of all the major agricultural greenhouse gases) have been reported to be "four times higher in irrigated compared to rain-fed systems".

Map of average growing season length from "Geography of Ohio," 1923. A season is a division of the year marked by changes in weather, ecology, and the amount of daylight. The growing season is that portion of the year in which local conditions (i.e. rainfall, temperature, daylight) permit normal plant growth.
Summer and early fall bring brief, but frequent thundershowers and tropical cyclones which create a wet summer and drier winter in the eastern Gulf and lower East Coast. During the winter, and spring , Pacific storm systems bring Hawaii and the western United States most of their precipitation.
Because of wheat’s central role in the global diet, crown rot represents a major economic concern. Not only is crown rot severe, it is also widespread. [9] Across the United States, average losses in winter wheat resulting from crown rot have been estimated to be as high as 9.5% through large areas of the Pacific northwest. [14]
