TABLE 15 THE EFFECT OF DATE OF PLANTING ON THE YIELD OF WINTER WHEAT. 



Fall wheat should uot be grown unless it can be planted at the 

 proper time on a fertile well-prepared seed bed. Fall rye is a very suc- 

 cessful crop and should be encouraged. 



The rate of sowing will vary with the time of planting and the 

 fertility of the soil. In general the rate recomniended in the Upper 

 Peninsula for a winter wheat is five to seven pecks per acre, and for 

 fall rye is four to six pecks per acre. 



The use of the fanning mill to insure clean seed, the use of seed 

 treatment to control smut and the germination test is as important as in 

 the treatment of spring sown grains. 



VARIETIES. 



Winter Wheat — There are two qualities which a fall wheat variety 

 to be successful in the Upper Peninsula must have, they are (1) winter 

 hardiness and (2) ability to withstand or evade rust epidemics. 



Considerable experimental work has been done with winter wheat 

 but as yet no outstanding variety has been discovered. The results this 

 past year gave a favorable impression of Kanred, a Kansas variety of 

 the Turkey Bed type which is proving itself quite winter hardy and 

 also resistant to rust but has a tendency to lodge under real favorable 

 conditions. Ked Rock, one of Professor F. A. Spragg's introductions, 

 has proven to be quite winter hardy but has not been able to withstand 

 rust attacks. 



Winter Rye — Rosen rye developed by Professor F. A. Spragg at the 

 East Lansing Station is the outstanding variety of the Upper Peninsula. 

 All comparative tests over the peninsula and at Chatham sub-station 

 have given Rosen a big lead over common varieties. Heni*y Berquist, 

 Stephenson, in 1918 obtained 43 bushels per acre with Rosen. Henry 

 Lukkarinen, Marquette county, in 1918 obtained 30 bushels per acre 

 from Rosen and only 22i/^ from Common.
