GREEN FORAGE AND HAY CROPS 111 
‘tions, as in the case of second-growth sweet sorghum, and must be 
fed with great care in the green condition (Fig. 14). 
Sudan grass (Andropagen sorghum var.) has been recently 
introduced into southern States. It is an annual, drought-resistant 
plant, closely related to the sorghums. It resembles Johnson grass 
somewhat in appearance, but, unlike this grass, it has no root- 
stocks and is not, therefore, likely to become a pest. Sudan grass 
makes a fair quality of hay, giving two cuttings in a season. The 
yields obtained will range from two to eight tons per acre, according 
to climatic and soil conditions. It is well suited for use as a soiling 
crop and may also prove valuable for the silo. This grass promises 
to be of special value to southern agriculture and in irrigated regions 
as a forage to be fed supplementary to alfalfa. é 
Millets.—The millets are annual forage plants. They are rarely 
grown for the sake of the seed in this country, as is the case in 
Asia, where millet seed is a common grain crop. They include a 
very large number of different species. Those grown in this country 
may be separated into four groups: The foxtail or common millet, 
broom-corn, barnyard, and pearl millets. The most important of 
the millets for sto¢k feeding are the German millet and the Hun- 
garian grass, both of which belong to the group: of foxtail millets. 
Millets are essentially hot-weather grasses and: are drought- 
resistant, which renders them especially valuable hay crops under 
semi-arid conditions. They are grown chiefly in central western 
States, like Kansas, Nebraska, and Missouri, for the purpose of 
supplementing the hay crop. Under favorable moisture conditions 
they will yield from three to five tons of cured hay per acre. They 
should be cut as soon as the blossoms appear; on account of the 
small, hard seeds and woody stems they make an unsatisfactory 
feed if the cutting is delayed till a later stage of growth. Cut early 
and fed in moderate amounts, the millets make a valuable hay for 
horses, cattle, and sheep. They should not be fed exclusively or for 
long periods at a time to horses, as they are likely to cause digestive 
and other troubles in that case. The millets do not differ greatly 
in chemical composition or feeding value from Indian corn fodder 
or sorghum, but are not relished by stock to quite the same extent. 
Foxtail is a common weed in grain fields and meadows in many parts of 
the country. It is especially troublesome in alfalfa fields in the western 
States. The first crop of alfalfa on old weedy fields is often rendered use- 
less through the growth of foxtail therein, unless it be cut early, while the 
beards are still soft and can be eaten without injury. If cut at this time,
