FIELD CROPS. 237 



the order of their yields, were: (Tolden Beauty, Mammoth Cuban, Western Yellow 

 Dent, Nebraska White Prize, Lenoeher Homestead, Star Learning, Iowa Silver Mine, 

 Western White Dent, Iowa Gold Mine, Pride of the North, and (ioddard King of 

 Earlies, all yielding over 67 liu. per acre. The average results for t\\o years show 

 yields of 71.9 bu. per aere with deep cultivation, and 82.4 bu. when shallow cultiva- 

 tion was given. Several of the most important varieties tested are described, and a 

 number of typical and imperfect ears are figured, and the selection of corn is dis- 

 cussed. A score card for judging ears is presented. 



Of 35 varieties of oats tested for 2 years in succession 12 gave an average yield of 

 over 50 bu. per acre. New Salt Lake gave the best yield, 58.8 bu. per acre, followed 

 by Silver Mine with 58.7 bu., Nebraska Gold Mine with 58.2, and Green ^Fountain 

 with 57.5 bu. per acre. The earliest variety, Early Champion, ripening .Inly 6, gave 

 an average yield per acre of 55.2 bu. White Russian, the latest variety, ripened 

 July 25, and gave the lowest average yield per acre, 39.3 bu. Early Champion and 

 Early Dawson are recommended as being little ai)t to rust and well suited as nurse 

 crops for clover and grasses. 



Of 19 varieties of barley grown for three years in succession, Manshury, Com- 

 mon 6-rowed, Success, Champion Beardless, and Black Hulless, with average yields 

 of 74.4, 70.4, 56.9, 53.8, and 44.4 bu. per acre, respectively, were best suited to Iowa 

 conditions. 



The yields for the season of 1900 of a number of cross-bred wheats grown since 

 1898 are reported. Of 24 varieties, the best yielding were Minnesota No. 71, Early 

 Java, Minnesota No. 185, White Russian, Preston, Minnesota No. 188, and Minnesota 

 No. 66, giving a yield of 33, 30.5, 27.5, 27.5, 26.8, 26.7, and 25.7 bu. per acre, respec- 

 tively. All varieties yielded over 19 bu. per acre. Early Java, a promising variety 

 obtained from southern Nebraska, ripened July 20. Growing wheat and oats in a 

 mixture of different proportions gave better yields than growing either alone. A 

 nnxture of 4 pecks of oats and 4 of wheat yielded 1,860 lbs. per acre, a better yield 

 than any other proportion of oats and wheat for seed. Spelt yielded 2,200 lbs. of 

 thrashed grain per acre in 1899 and 1,960 lbs. in 1900. Sorghum sown May 21 and cut 

 August 27 yielded 29 tons of green fodder or 12 tons of sorghum hay per acre. The 

 use of 40, 80, or 120 lbs. of seed per acre gave practically the same results as to yield, 

 but the thicker-sown crop grew better and contained more water and less saccharine 

 matter than the crop from thinner sowings. Sorghum, sown after barley had been 

 harvested in July, was about 7 feet high and in full head by September 20. It was 

 cut September 29 and gave 21 tons of green sorghum per acre, which cured into 7 tons 

 of hay. 



Rape sown May 24 and harvested on September 10 yielded 21 tons per acre in 1898, 

 and in 1899 60 bu. of oats and 18 tons of rape were grown on an acre when 6 pecks 

 of oats and 1 lb. of rape were sown together in the spring. In 1900 rape and oats 

 sown together were successful only on the higher and poorer land. On bottom land 

 the rape completely smothered the oats, even when sown 10 days later. Successful 

 culture tests of kohl-rabi and soy beans are reported. Owing to a wet season the 

 work with sugar beets did not give satisfactory results.

 tests with cereals, root and forage c-rops were carried on at the experimental farms in 

 Ottawa, the Maritime Provinces, Manitoba, British Columbia, and the Northwest 

 Territories (E. S. R., 12,p. 535). The results of the variety tests with the different 

 crops in 1900 have been previously reported ( E. S. R., 13, p. 34). Tiie plan and scope 

 of the experiments this season were practi(;ally the same as described in preceding 

 abstracts, and the results are reported in the usual form. Owing to the prevalence
