have a good seed-bed. The latter is then more important 

 than early seeding. The particular date will of course 

 be earlier toward the north. In northern Kansas, winter 

 wheat seeding should be about September 15-20, in 

 southern Kansas, September 20-25. Rye can be sown a 

 little later. Winter barley should be sown a little earlier 

 than winter wheat. When the Hessian fly is prevalent, 

 it may be wise to delay seeding (522). In Oklahoma, 

 September 25 to October 5 appears to be about the right 

 period for seeding winter grain. 



Results of experiments at the Amarillo, Texas, Cereal 

 Field Station show that winter wheat should be sown in 

 Texas Panhandle about October 15 to November 1. In 

 similar experiments with winter barley at Channing, 

 Texas, about October 7 seemed the best date for that 

 crop. At this place late seeding of winter barley seemed 

 to reduce strikingly the quantity of loose smut in the crop 

 (Ross and Leidigh, 1913, pp. 29, 45-47). 



At the Judith Basin, Montana, substation, experiments 

 on the date of seeding Turkey winter wheat for 5 years re- 

 sulted in August 1 giving the best average yield, though 

 September 1-7 was nearly as good, and better than 

 August 13. As September 15-20 gave still poorer results, 

 it seems only that some date in August is the proper time 

 (Atkinson, 1914, p. 155). In Alaska, winter rye and winter 

 wheat must be sown early in August or last of July. 



393. Time of spring seeding. For spring cereals, 

 also, comparatively early seeding is usually preferable, in 

 order that the crop may escape the midsummer drought. 

 The proper date is later toward the north. The actual 

 date will often be governed largely by the quantity of 

 moisture in the soil. If the soil moisture is deficient for 

 some time, seeding may be much delayed. On this ac-
