All or part of the field may be hogged down. Four to eight acres can 

 be fenced off at a time. When the area is cleaned up, fences should 

 be moved to include an equal area of standing corn. 



Under average conditions, in corn yielding 40 bushels or 80 baskets 

 per acre, 4 to hogs can be carried per acre. Heavier yields will carry 

 more hogs. It will take 6 to 8 weeks for four or six hogs to clean up an 

 acre of good corn. 



It is advisable to plant rape, rye, or soybeans with corn which is to 

 be hogged down. Kape should be planted at the rate of two pounds 

 per acre of Dwarf Essex Rape at the last cultivation and rye at the rate 

 of one bushel per acre at the last cultivation. A mixture of the rape and 

 rye is often more effective for late fall pasture than either seeded alone. 

 Rye and vetch, at rates of 1 bushel of rye to 20 pounds of hairy vetch, 

 is another excellent seeding to be made with corn at the last cultivation. 



Six or eight pounds of soy beans, drilled in with planter attachment or 

 immediately after corn is planted, furnish additional forage for hogs. 



Rye can be grown separately to furnish an early grain for hogging 

 off. 



Professor G. A. Brown of the Department of Animal Husbandry sug- 

 gests that a protein supplementary ration be fed in cases where rape, 

 rye or soy beans fail. In addition to the corn being hogged off, he 

 suggests the feeding of skim milk or tankage. 



CORN IX ROTATION 



The corn crop is well suited to Michigan's cropping systems in all 

 sections where it is adapted. Corn is an excellent crop to grow after 

 meadow or pasture crops. The plant has been described as a "rough 

 feeder," owing to the fact that it can apparently make the best use of 

 organic matter, such as sod and manure which has not yet become 

 thoroughly incorporated with the soil. It is a crop which requires 

 thorough cultivation ; hence, offers excellent opportunity for the control 

 of weeds and grass after a sod. Preparation of the land for corn, and 

 the cultivation given the crop, leave the ground in excellent condition 

 for a following crop of small grain. 



Growing corn in rotation aids in maintaining fertility and prevents 

 extreme loss from insect pests or diseases. Corn smut does most dam- 

 age where corn follows corn for a number of years. Growing corn in 

 rotation with other crops is the only effective means of keeping this 

 disease in control. Occasionally considerable damage is done to corn, 

 when planted after an old sod, by the grubs or larvae of the June Beetle, 

 Early plowing and thorough working will minimize such loss. Fall 

 plowing is particularly effective. A newly turned meadow or pasture 

 sod will pave the way for a large corn crop. 



The usual rotations including corn are the following: 



1. Three year rotation: the first year, clover or meadow; second 

 year, corn ; third year, small grains seeded to clover. 



2. Four year rotation: first year clover; second year, corn; third 

 year, oats, and fourth year, wheat seeded to clover. 



3. Four year rotation including beans, and beets: first year, clover; 

 second year, corn, beans or beets; third year beans, beets or corn; and 

 fourth year oats seeded. 



4. Five year rotation including timothy, and clover meadow : first
