GRASS-CROP AREAS 87 
The leading alfalfa states are all west of the Missouri 
River, although it is note-worthy that the state of first 
rank, Kansas, lies on the eastern border of the region. 
With the exception of Tennessee, the leading millet 
states lie between the Mississippi River and the Rocky 
Mountains. 
The states leading in the production of forage classi- 
fied as “other tame or cultivated grasses” are those of 
the New England division, together with the adjacent 
state of New York, and the more remote states of Minne- 
sota, Kentucky, Tennessee and Texas. In the north- 
eastern states the most important element is redtop. In 
Texas, as in other southern states, Johnson-grass is an 
important factor. In Tennessee and Kentucky orchard- 
grass is an important forage plant. The states leading in 
the production of wild hay, with the exception of Wis- 
consin, lie in the Great Plains region where the bulk of 
the product is made up of mixed prairie grasses. In Wis- 
consin an important factor is blue-joint (Calamagrostis 
canadensis). 
Most of the elements in the classification of hay and 
forage represent summer-grown crops. The category 
referred to as “grains cut green”? assumes importance in 
two regions, the Pacific coast and the southern states. In 
the first region the best conditions for grain-growing 
obtain in the winter season, during which the greatest 
rainfall of the year occurs. Because of these conditions 
hay made from grain is the most available forage. In the 
second region cowpea hay is an important crop. Canada 
field pea, an important crop along our northern border, 
is included in the figures for ‘‘grains cut green.’”’ Under 
the last heading, ‘‘coarse forage,” are included corn and 
sorghum cut for forage.
