HAIRY-VETCH SEED PRODUCTION. Mal 
is kept down by pasturing until the first blossoms appear. A mower 
is then run over the field to level the stand and unless the weather 
becomes very dry and hot a second growth of short stocky vines is 
sent up from the roots. These vines are quite heavily set with pods 
and are easily harvested. Such a seed crop is 10 days to 2 weeks 
later than that from the first crop, but is often of more uniform qual- 
ity. The chief objection to the practice is the danger of hot weather 
coming before the second crop is started, killing the plants. In no 
case should the vetch be pastured or mowed later than the first show 
of blossoms, as after that the plants are unable to recover. : 
USE IN THE ROTATION. 
Hairy vetch is sometimes grown with rye in the South, but more 
commonly with winter oats, which is a better hay plant and matures

more nearly with vetch. Abruzzes rye and Appler oats or other 
improved varieties are used quite generally by the hairy-vetch 
srowers. In the more northern counties, barley is preferred to 
either oats or rye, being more winter hardy than the former and more 
palatable than the latter. 
Because of the long growing season, the hairy-vetch seed crop 
fits into a greater variety of rotations in the South than in the North. 
Ordinarily the crop is sown in corn, cotton, or cowpeas at the last 
cultivation or follows directly after early potatoes, soy beans, or 
grain. (Fig. 7.) In many of the poorer soil areas, the hairy vetch 
is grown continuously until the soil has become rich enough for other 
crops. Cotton is especially useful to precede hairy vetch, as the
