given uniformly poor results. Alfalfa seeded shortly after the grain has been 

 removed in the late summer has given the most satisfactory stand and produced 

 higher yields the first year after planting. Early-seeded spring grains have 

 given much better results as to both quality and yield than late-seeded spring 

 grains." 



In variety testing with winter cereals, reported by J. H. Martin, Turkey 

 selection wheat has given the highest average yield, 36.3 bu. per acre, for the 

 '.' years 1915 to 1917. inclusive. Kharkof was second with an average yield of 



35.7 bu. Swedish (Minn. No. 2) and North Dakota No. 998 rye produced 25,5 

 bu. and 25.3 bu. per acre, respectively. Winter emmer and winter spelt have 

 not proved sufficiently hardy for this locality. BZubanka, a durum variety, has 

 produced the highest average yield of the spring wheal varieties tested, with 



21.8 bu. for the period of 1913 to 1917. inclusive Marquis, with an average 

 yield of 16.8 bu., is deemed the besi common wheat White Russian oats, a late 

 variety, has given the highest average yield for the past yean, 45.8 bu. per 

 acre, while Silvermine, With B .''.-year average yield of 51.6 bu.. is said to be 

 one of the most promising of the midseason sorts. Early oats have not proved 

 very productive under Irrigation. Hannchen and Ohevalier barleys, 2-rowed 

 types, have outylelded all the 6-rowed varieties. Chevalier II produced an aver- 



of 31.1 bu. per acre for the 4 years 191 1 to 1917, as compared with 20.3 bu. 

 for Manchuria (Wis. No. 13); Hull-less types have produced from 19.2 to 

 bu. for the same period. While spring emmer yielded 4&3 bu. for a 4-year aver- 

 but the yield In pounds of grain per acre has l a somewhat less than that 



of the better varieties of barley. Damont hax has given the highest av. 

 yield for the past 4 years, 13 bu. per acre, with Russian (N. Dak. No. 15.". i 

 ond with 12.6 l ui. 



Marten White Dent. Northwestern Dent, and Payne White I rn have 



produced average yields for the B years, 1913 to 1917, amounting to 42.8, 42.7, 

 and 40.9 bu. per acre, respectively. Genu Flint has yielded an average of 

 39.8 bu. for the pasl .". years and is said to be the earliest ripening of all the 

 varieties. Marten White Dent, Payne White Dent, Red Cob, and Sweet Fodder 

 corn, grown for silage in comparison with Mammoth Russian sunflower, pro- 

 duced 9.55, n»..">7. 11.98, and 8.67 tons per acre, respectively, the average yield 

 for the sunflowers being 12.59 tol

 Agr. So. Aust., 21 (1918), No. 7, pp. 576 588).— Variety, cultural, and fertiliser 

 tests with wheat conducted at three experimental centers during the seasons 

 of 1916 and 1917 are reported, In continuation of work previously noted (B. 3. 

 It., 38, p. 433). 



Rolling the land after plowing for wheat gave practically the same yield. 

 about 16.3 bu. per acre, for 6 in. plowing as BUbpacfclng after plowing. For 

 8 in. plowing the respective yields were approximately 15.5 and 14.5 bu. 

 See also an earlier note (B. S. R., 38, p. 240). 



Applications of 2 and 3 cwt, o( superphosphate per acre materially Increased 

 wheat yields.
