The yield peracre of corn has remained remarkably constant for 55 years, of hay and wheat has in-creased about one-sixth, but the yield per acre of cotton has declined notably since 1914In general, production nad kept pace with population until recently, not primarily be-cause of increasing yields per acre, but mostly because of expanding crop acreage. A Graphic Summary of Amerk-an Ag^-iculture. 433. Fig. 21.—The eastern half of the United States produced in 1919 about 86 pev centof the value of all crops of the Nation ; the value of the crops produced in the CottonBelt and the Corn Belt being nearly 50 per cent. The value of the crops per squaremile of land area was about . in the Corn Belt, and $8,700 in the Cotton Belt, to only $673 in the Arizona-California Desert Region ; but the value per acrein crops was highest in the .irizona-California Desert ($95), where all crops areirrigated, and lowest in the Great Plains Region ($21), where most of the crops aregrown under semiarid conditions. 434 Yearhooh of the Department of AgricvZture, 1981.
