CORN. 



The corn on both the pasture rotation and the harvest rotation 

 died of drought before making grain, and no yields were obtained. 



ALFALFA. 



A scarcity of fall pigs and the poor condition of the alfalfa pastures 

 necessitated using half-acre areas. The areas having the best stand 

 of alfalfa were fenced off and used for grazing. Both the broadcast 

 and row plats were stocked on May 19 at the rate of six pigs per 

 acre. The lot placed on the row plat totaled 772 pounds per acre, 

 while that on the broadcast plat weighed 728 pounds per acre. 



The alfalfa on each plat, though somewhat thinner as to stand than 

 desirable, was about 6 inches high and seemed to be making a good 

 growth. Though the season was dry, the crop made continuous 

 grazing for a period of 70 days. The pigs were removed on July 28. 



The pigs on the row plat increased 436 pounds per acre, or at the 

 rate of 1.04 pounds per day each and at the ratio of 1 pound of gain 

 to 3.04 pounds of corn. The pigs on the broadcast plat made a total 

 gain of 402 pounds per acre, which averaged 0.96 of a pound per pig 

 per day. This lot had a ratio of 3.3 pounds of corn fed for each 

 pound of gain. 



No alfalfa was obtained from the check plats because of drought 



BROME-GKASS. 



In order to use areas having fairly uniform stands of brome-grass 

 for pasturing, one-half acre of the row plat was used and one-fourth 

 acre of the broadcast plat. When the pigs were placed on these plats 

 on May 19, the brome-grass averaged 6 inches in height. The stand 

 on each plat was thinner than was desirable. 



The row plat was stocked at the rate of six pigs per acre, with an 

 initial weight of 732 pounds. The lot on the broadcast plat was at 

 the rate of eight pigs per acre, totaling 1,01^2 pounds. The row plat 

 produced continuous grazing for a period of 70 days, but on the broad- 

 cast plat the hogs had to be removed at the end of 62 days. 



A gain of 0.74 of a pound per day for each animal, or 310 pounds 

 per acre for the lot, was made on the row plat, while the individual 

 daily average of the pigs on the broadcast plat was 0.9 of a pound, or 

 a total of 436 pounds per acre. 



Corn fed to the row-plat hogs totaled 1,246 pounds to the acre, or 

 4.02 pounds of corn for a pound of gain. The pigs on the broadcast 

 plat received an acre total of 1,412 pounds of corn, or 3.24 pounds of 

 grain for each pound of gain. 



No yields were obtainable from the check plat of brome-grass 

 because of the drought. 



The duplicate perennial pastures seeded in 1919 and fallowed in 1920 

 were reseeded in the spring of 1921. 



STUDY OF THE RESULTS WITH DIFFERENT CROPS.* 



The data on pasturing the four crops, rye, peas, barley, and corn, 

 in the 4-year rotation for the years from 1916 to 1921, inclusive, are 

 assembled in four tables, one for each crop. The averages at the 

 bottom of each table were determined for the number of years the 

 crops were actually pastured, exclusive of 1915. 



* For Information on the pasturing of irrigated crops with hogs and the feeding of hogs while on pasture 

 and in the feed lot, see the published reports of the work of the Huntley experiment farm, Bureau of Plant 

 Industry, for the years 1913 to 1921, inclusive, by Dan Hansen, Farm Superintendent.
