430 EXPEEIMENT STATION KECOED. 



grown in this test. One-half acre of this variety planted in the fall and irri- 

 gated but once in the spring yielded at the rate of 2,3T6 lbs. of grain per acre. 

 A yield of 2,763 lbs. of grain was produced per acre foot of water. 



In a culture test with root crops 1 acre of the long red mangel produced 

 15.8 tons. 



Results of cooperative experiments in agriculture, J. Buchanan {Ann. 

 Rpt. Ontario Agr. and Expt. Union, 28 {1906), pp. 13-27). — Earlier results of 

 this work have been previously reported (E. S. R., 18, p. 27). 



In the cooperative experiments of 190G the leading varieties of grain crops 

 gave the following average yields per acre: Siberian oats, 104 tests, 51.18 bu. ; 

 Mandscheuri Six-rowed barley, 57 tests, 37.95 bu. ; Two-rowed Canadian bar- 

 ley, 3 tests, 23.88 bu. ; Guy Mayle Hulless barley, 14 tests, 22.19 bu. ; Wild 

 Goose spring wheat, 23 tests, 24.19 bu. ; Common emmer, 11 tests, 39.4G bu. ; 

 Red spelt as compared with emmer, 27.64 bu. ; Japanese buckwheat. 3 tests, 

 27.78 bu. ; Early Britain field peas, 55 tests, 23.79 bu. ; White Wonder field 

 beans, 17 tests, 20.05 bu. : Early Yellow soy beans, 1 test, 16.33 bu. ; Banatka 

 winter wheat, 17 tests, 30.01 bu. ; Comptou Early corn, 16 tests, 60.16 bu. The 

 best and most popular mixture of grains consisted of 34 lbs. of Daubeney oats 

 and 48 lbs. of Mandscheuri barley per acre, which produced on the average in 

 12 tests 1,505 lbs. of grain per acre. In all cases except two the varieties here 

 mentioned ranked first in popularity, Mandscheuri barley and Early Britain 

 field peas being the exception. 



The leading varieties of field roots and fodder crops gave the following yields 

 per acre : Yellow Leviathan mangels, 7 tests, 42.66 tons ; Giant White Feeding^ 

 sugar beets, 7 tests. 39.13 tons; Sutton Magnum Bonum swedes, 6 tests, 20.83 

 tons; Mastodon White Intermediate carrots, 5 tests, 18.26 tons; Buckbee New 

 Sugar parsnips as compared with carrots, 14.19 tons; Henderson Eureka fodder 

 corn, 4 tests, 16.75 tons; Japanese Barnyard millet,-^ tests, 12.03 tons; Kafir 

 corn, 1 test, 9.80 tons ; Early Minnesota sugar cane as compared with Kafir corn, 

 9.24 tons; Dwarf Bonanza rape, 1 test, 25.48 tons. In 3 tests hairy vetches, 

 grass peas, and common vetches gave 7.87, 7.31, and 6.75 tons per acre, respec- 

 tively. Nearly all these varieties were the most popular with the experi- 

 menters, excepting Mastodon White Intermediate carrot and Henderson Eureka 

 fodder corn, which were outranked by Bruce Mammoth Intermediate carrot 

 and White Cap Yellow Dent fodder corn, respectively. Grass peas and common 

 vetches were preferred to hairy vetches. Mangel seed sown on the level pro- 

 duced a yield of 33.3 tons of roots per acre as compared with 30.7 tons where 

 the seed was sown in drills. 



Ringleader, Golden Bantam, and Mammoth White Cory sweet corn, requiring 

 70, 73, and 74 days, respectively, to mature for table use, were grown in 20 tests. 

 In comparative value. Ringleader and Mammoth White Cory outranked Golden 

 Bantam, which stood first in table quality. 



In the fertilizer experiments conducted in the previous years the greatest 

 average yield of oats for 5 years in 74 tests was secured by the use of the com- 

 plete fertilizer, while the greatest average yield of mangels for 5 years in 41 

 tests was obtained where nitrate of soda was applied. The total yield of fodder 

 corn for 8 years in 47 tests was the same from the use of nitrate of soda, the 

 complete fertilizer, and of muriate of potash. l)ut the yield of husked ears was 

 slightly in favor of the complete fertilizer. The highest average yield of swedes 

 for 4 years in 12 tests, 30.1 tons per acre, was secured where 40.000 lbs. of cow 

 manure was applied per acre. 



The average yields of 3 late varieties of potatoes, Empire State, Dempsy 

 Seedling, and American Wonder, grown in 86 tests, were, respectively, 174.67, 

 168.49, and 165.80 bu. per acre. Of 3 medium varieties, grown in 70 tests. Rose
