It depends greatly on location, type of wheat, and different farming practices. In top wheat producing states Kansas, North Dakota, and Montana, non irrigated wheat yields are typically 30-50 bushels per acre with there being 60 lbs in a bushel. Irrigated yields in certain areas are over 100 bushels per acre. The highest non irrigated or dry land wheat yields in the nation are in the palouse region of Eastern Washington and Northern Idaho. Winter wheat yields in Whitman county Washington averages 83 bushels an acre and Latah county Idaho averages 82 bushels an acre. Yields of up to 150 bushels an acre have occurred there. The USA came 45th in yield for the 2010/2011 crop, with an average of 46.4 bu. The Netherlands came first, at 132.5 bushels per acre (almost 3 times the USA yield.)
North Dakota and Kansas are the top contenders, and usually play with first and second place. However, in 2011, Kansas was the top producer of wheat.
Kansas produced the most wheat in 2008, but North Dakota produced the most in 2007, 2009 and 2010.
It varies from year to year, of course, but the average is 41 bushels per acre for the period 2006 through 2011.
Kansas produced the most wheat in 2008 and 2011, but North Dakota produced the most in 2007, 2009 and 2010.
There's too many variables here to be able to answer this question. However, just for example, the US average yield from all states of all barley types for the period from 2006 through 2011 is 66.7 bushels per acre, according to the USDA.
In 2011, Iowa produced 2.4 billion bushels of corn. Nebraska produced 1.5 billion bushels of corn. Illinois produced 1.9 billion bushels of corn.
This question cannot be answered as is because since there are multiple crops, there are also multiple answers. For example, for the 2011 crop year, North Dakota produced the most spring wheat and flaxseed, Idaho produced the most barley, and South Dakota produced the most sunflower.
