Wheat is produced in almost every state in the United States, and is the principal cereal grain grown in the country. The type and quantity vary between regions. The US is ranked third in production volume of wheat, with almost 58 million tons produced in the – growing season, behind only China and India (But the combined production of all European Union.

Factors Influencing Wheat Yield and Variability: Evidence from Manitoba, Canada Article (PDF Available) in Journal of Agricultural & Applied Economics 41(03). Agric. Meteorol., Wheat yields were examined for evidence of increased variability of weather and its synchronous variation in different farming regions.

Since in Argentina, Australia, Canada, India, and the United States, the standard deviation of wheat yields has not changed by: 8. This data product contains statistics on wheat—including the five classes of wheat: hard red winter, hard red spring, soft red winter, white, and durum and rye.

Includes data published in the monthly Wheat Outlook and previously annual Wheat Yearbook. Data are monthly, quarterly, and/or annual, depending upon the data series. This statistic shows the yield of wheat per harvested acre in the United States from to According to the report, the U.S.

Agric. Meteorol., The variability of wheat yields in England and Wales from to has been ana- lysed and compared with the results for other countries obtained by Waggoner ().

It is suggested that variations in yield from year to year were proportional to mean by: 3. County-level crop yields and daily precipitation and temperature data are pooled to quantify the impact of climate variability and extremes on four major staple crops in the United States.

Farmers have seen greater variability in winter wheat yields over the past decade than they did in the previous five years, according to analysis by Strutt & Parker.

They have tracked crop performance through its annual harvest survey, has identified that while average winter wheat yields have slowly climbed since its survey began 19 years ago.

The 30 year long (–) ° annual yield time series of maize, soybean, rice and wheat obtained from the global data set of historical yields [] and its update were data set includes two different types of grid-cell yields—uniformly disaggregated subnational yield statistics (or aggregated for small administrative units) reported by.

Wheat ranks third among U.S. field crops in planted acreage, production, and gross farm receipts, behind corn and soybeans. In /17 U.S. farmers produced a total of billion bushels of winter, other spring, and durum wheat on million acres of cropland.

Wheat production costs in the United Statesby type of cost Volume of insured acres of wheat U.S. U.S. annual sales of wheat for food Wheat grain yield levels are known to vary from 1 year to the next and this variability is frequently attributed to differences in rainfall.

However, within field variability of wheat grain yields as a function of time has not been extensively evaluated. Wheat grain yields from selected fields in Oklahoma were monitored.

Wheat is a grass widely cultivated for its seed, a cereal grain which is a worldwide staple food. The many species of wheat together make up the genus Triticum; the most widely grown is common wheat (T. aestivum).The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around BCE.

Botanically, the wheat kernel is a type of Clade: Tracheophytes. H istorical grain yields offer us a glimpse of yields yet to come, although like the stock markets, past performance is no guarantee of the future.

The historical yield data for corn in the U.S. illustrate the positive impact of improved crop genetics and crop production technologies. American farmers grew open-pollinated corn varieties until the rapid adoption of hybrid corn.

While agriculture in the United States continues to achieve enhanced productivity, it is also experiencing greater variability in crop yields and associated farm income in recent decades.

The increased yield variability is, in part, directly related to increases in extreme weather events during critical growth phases of crop develop-ment. The overall winter wheat yield for was t/ha, which was up 2% on the previous year’s average of t/ha.

The increase was largely attributable to the better performance of first wheats which yielded an average of nearly t/ha, compared to t/ha in Wheat growers frequently need to estimate wheat yields in the spring in order to make decisions about. potential recropping. This NebGuide discusses three methods of estimating winter wheat yield.
