BULLETIN 752, U. S. DEPARTMENT OF AGRICULTURE. 
ful production of field peas requires a wise selection of a variety 
from a very large number and careful attention to the cultural re- 
quirements of the crop. The crop undoubtedly is adapted to the con- 
ditions in most irrigated districts, except, perhaps, those in the South- 
west, where high summer temperatures prevail. The present indica- 
tions are that, as farmers learn to grow the crop successfully, its use 
as hog feed will be widely adopted. 
Data are available from 18 of these tests in which field peas were 
hogged off. In eight of these tests the peas were grown without addi- 
tional grain. In six tests the peas were grown with wheat. Peas 
were mixed with oats in one case and with barley in three cases. In

Fig. G. — A field of peas being pastured off by hogs on an irrigated farm. This field con- 
tained 4.6 acres, and 97 shotes gained at the rate of 843 pounds per acre in 37 days. 
12 of the 18 tests no supplementary feed was given. In the remaining 
instances the pigs had access to alfalfa from which usually the sea- 
son's hay crops had been harvested. The time of turning the pigs 
into the field in these tests ranged from late July to mid- September. 
The pigs may be turned in as soon as the peas show signs of ripening. 
The duration of the hogging period will depend on the time required 
to clean up the crop. This depends on the size of the crop and the 
age and number of the pigs. In these tests the hogging period ranged 
from 12 to 68 days. A view of one lot of pigs (lot 15 in Table XX) 
in a field of peas is shown in figure 6. 
The very wide diversity in the results secured was due largely to 
the variation in the size of the crops hogged off. The tests were all 
conducted on practical farms in cooperation with their owners on 
five reclamation projects. The results are presented in Table XX.
