352 EXPERIMENT STATION RECORD. 



emmer, 7 tests, 56.85 bu.; Red spelt as compared with emrrmr, 31.58 bu. ; New Cana- 

 dian Beauty field peas, 22 tests, 30.03 bu.; Silver Hull buckwheat, 4 tests, 23.38 bu.; 

 Marrowfat field beans, 10 tests, 30.:;:; bu.; Imperial Amber winter wheat, 3 tests, 

 22.47 bu.; and King Philip corn, 9 tests, 55.99 bu. 



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

 arte: Yellow Leviathan mangels, 5 tests, 29.31 tons; New Danish Improved sugar 

 beets, 9 tests, 31.29 tons; Magnum Bonum Swede turnips, 4 tests, 22.17 tons; Redtop 

 White Globe turnips, 1 test, 33.48 tons; Mammoth Intermediate Smoot White 

 carrots, 2 tests, 16.16 tons; Henderson Eureka fodder corn, 2 tests, 21.22 tons; Early 

 And >er sugar cane sorghum, 1 test, 18 tons; grass peas in comparison with vetches, 

 4 tests, 5.90 tons; and Dwarf Essex rape, 1 test, 25.72 tons. Dwarf Bonanza rape 

 gave a yield almost as large as Dwarf Essex. 



The leading varieties of hay crops were Japanese Barnyard millet, Mammoth red 

 clover, lucern as compared with sainfoin and Burnet, and tall oat grass tested with 

 several other common grasses. The results with sowing hairy vetches, winter rye, 

 and crimson clover in the fall show that hairy vetches gave a yield of 6.8 tons and 

 winter rye of 4.3 tons of green crop per acre during the last 2 seasons, while crimson 

 clover was badly winterkilled in each of the 2 years. 



The average yields of Empire State and American Wonder potatoes, 2 late varieties 

 grown in 62 tests, were 224.5 and 221.8 bu. per acre, respectively. Of medium early 

 varieties Rose of the North stood first, with an average yield of 200.4 bu. per acre in 

 55 tests, while among the early varieties, Early Andes in 163 tests ranked first with 

 170.8 bu. Hilling potatoes gave better results than level cultivation, which is con- 

 sidered due to a cool, damp season. The results of 17 tests show that seed potatoes 

 coated with land .plaster yielded 228.2 bu., as compared with 213.2 bu. per acre for 

 untreated seed. 



In 1904 experiments with fertilizers were confined to swedes, and the yields 

 obtained per acre for the different methods of treatment were as follows: Check plat 

 24 tons; 160 lbs. of nitrate of soda per acre, 26.1 tons; 160 lbs. of muriate of potash, 

 26.7 tons; 320 lbs. of superphosphate, 28.1 tons; 213 lbs. of complete fertilizer, 29.3 

 tons; and 40,000 lbs. of cow manure, 32.5 tons. 



In 8 tests with sweet com Mammoth White Cory ranked first in yield, quality, 

 and earliness. This variety required only 71 days to produce ears ready for table 

 use. Field corn planted in hills yielded 2.14 tons of ears per acre, while corn in 

 drills yielded 1.58 tons. In total crop the average of 4 tests showed but little differ- 

 ence between the 2 methods of planting. 



Report on the manuring of seeds hay, 1904, W. Allan (Edinb. and East of 

 Scot. Col. A (jr. Bui. 5, pp. 21). — Fertilizer experiments in connection with growing 

 different grass mixtures were conducted at 21 centers. 



Nitrogen was used at the rates of 20, 30, and 40 lbs. and phosphoric acid and potash 

 at the rate of 40 and 30 lbs. . respectively. Nitrogen proved to be the most effective 

 element, the best results being obtained where a mixture of nitrate of soda and sul- 

 phate of ammonia was used. When the 2 substances were applied alone, nitrate of 

 soda gave better results than sulphate of ammonia. The largest quantity of nitrogen 

 used gave a larger yield and better financial returns than the smaller quantity. 



When applied alone nitrogen gave. satisfactory results, but potash and phosphoric 

 acid each given alone were not very effective. The largest yields and the greatest 

 profits in the entire series of tests were obtained from the use of complete applica- 

 tions. 



Culture and fertilizer tests on heath soils, B. Hardt (Deut. Landw. Presse, 32 

 (1905), Xo. 29, pp. 253, 254). — Experiments were conducted for 4 years to deter- 

 mine the effects of lime and marl on new heath soil, and to ascertain the possibility 

 of growing oats under such soil conditions.
