of the Upper Peninsula shows that May and June are ideal growing 

 months and from July 1 to August 15 is usually weather favorable to 

 kernal development and ripening. This would indicate that about May 

 1 is the time to sow spring grains in this area so as to make the best 

 use of our weather conditions. The practice of our most successful 

 farmers is to sow their spring grains as early in May as possible. 



RATE TO sow PER ACRE. 



This is a cultural practice that will vary with the grain crop grown 

 and the type of soil under cultivation. The usual rate for spring wheat 

 is from 5 to 8 pecks per acre. When seeded early on a well-prepared 

 seed bed with a soil suitable for wheat, 6 pecks is about right. Oats 

 should be sown at the rate of 8 to 12 pecks per acre. Ten pecks is about 

 right for the average soil, 8 pecks on the lighter soils and 12 pecks on 

 the real heavy soils. Barley should be sown at about 8 pecks per acre 

 on average soil, about 7 pecks on light soil, up to 9 or 10 on the heavier 

 soils. 



Field peas* are so variable as to size that it is difficult to recommend 

 a definite rate for sowing. The smaller sorts, such as the French June 

 and Golden Vine at about 2 bushels per acre. The medium-sized, like 

 English and Arthur, at from 21^ to 3 bushels. The larger sorts, like 

 the Marrowfat, from 3 to 3l^ bushels. 



TABLE 12 RATE OF SOWING SPRING GRAINS.f 



fAlI tabulated data pertaining to cropte In this publication is tlie result of experimental 

 work done at the U. P. sub-station of the Michigan Agricultural College, at Chatham, Mich., 

 unless otherwise noted. 



The preceding data confirm the rates recommended in the preceding 

 paragraph. In some sections there is a tendency to sow heavier on the 

 lighter soils than on the more fertile ones. This is contrary to our knowl- 

 edge of light soils, as they tend to be more droughty and less fertile and 

 a somewhat lighter seeding will utilize available moisture and plant 



•Field peas, as a grain feed crop, occup.v a place in our s.vstem of cropping in the 

 Upper Peninsula very similar to the small grains, so they are herein treated under the 

 same cultural heading.
