count, the range in time of seeding may be considerable. 

 It extends from about February 25 to April 15, at Amarillo, 

 Texas, though in one year best results with oats were 

 obtained from May seeding. Late-sown spring grain is 

 apt to rust. 



Results of experiments, so far, indicate that April 15 

 to May 1 is the best period for seeding spring grains at 

 Archer, Wyoming, which would apply to considerable 

 adjoining portions of Nebraska and Colorado. In North 

 Dakota, it appears to be the general experience that a 

 medium date of seeding is safer than either late or early 

 seeding. Near April 15 seems a good average time in the 

 state. In Saskatchewan, it is recommended to sow from 

 May 15 to 25. In Alaska, spring grain is sown May 10 

 to 20. 



In Oklahoma, early seeding of an early variety is con- 

 sidered to be important. At the Kansas Station, in two 

 years' experiments, about March 30 was found to be the 

 best time for seeding both oats and barley. It is stated 

 that oats should be sown " as early in the spring as the 

 soil is in fit condition; and in order to prepare an early 

 seed-bed, and have the soil well settled and in good tilth, 

 the ground should be fall plowed for oats " (Ten Eyck 

 and Shoesmith, 1904, p. 190). 



394. Rate of seeding. In the Great Plains area, the 

 best rate of seeding is usually less than in the Eastern 

 area. For eastern Colorado, the following rate to the 

 acre has been recommended : Wheat 45 to 60 pounds ; 

 oats 40 to 60 pounds ; barley 50 to 60 pounds ; rye 35 to 

 50 pounds; and emmer 45 to 60 pounds. There should 

 be little or no difference in rate of seeding in different 

 latitudes, but the rate should decrease a little as dryness 

 increases.
