36 EXPERIMENT STATION RECORD. 



The varieties of sweet corn tested and the number of days required for their growth 

 for table use were as follows: Mammoth White Cory, 95 days; Crosby, 111 days; 

 Country Gentleman, 125 days. Crosby appeared to lead in quality. Five varieties 

 of potatoes grown in 227 tests gave the following yields: Empire State, 221.9 bu.; Bur- 

 pee Extra Early, 172.6 1m.; Early Pinkeye, 164.1 bu.; Early Ohio, 125.lM.ii.; Stray 

 Beauty, 118.8 bu. Level culture has given slightly better yields than hilling. The 

 average results for 4 years show that sprinkling seed potatoes with land plaster 

 increased the yield about 9 bu. per acre throughout Ontario. 



Culture experiments in 1902-3, A. Damseaux {Bui. Agr. [Brussels'], 20 {1904), 

 No. l,pp. 34-43). — The yields perare of the leading varieties of cereals undertest in 

 1903 were as follows: Schlanstedt rye, 34 kg. of grain and 97 kg. of straw; < Jros bleu 

 spring wheat, 34 kg. of grain and 76 kg. of straw; Albert barley, 48 kg. of grain and 

 60 kg. of straw; and Kirsche oats, 45 kg. of grain and 80 kg. of straw. 



An experiment was made to determine the influence of lime on the action of 

 superphosphate. Sugar beats which in addition to superphosphate had received 

 4,000 kg. of lime per hectare developed well, indicating that the efficiency of the 

 superphosphate was not diminished. When 8,000 kg. of lime per hectare was 

 employed the quality of beets was reduced through deformity. It was also shown 

 that barley was more sensitive to a heavy application of lime in connection with 

 superphosphate than oats. The author concludes that where the application of lime 

 is increased the quantity of superphosphate should be increased in proportion to 

 avoid an excess of lime which in many cases renders phosphoric acid insoluble. 



The study of the substitution of sodium for potash was made with oats and barley 

 grown in pots. The yield of oats with a complete fertilizer was 12 gm. per pot; with 

 the same application without potash, 6 gin.; with the complete application in which 

 the potash was replaced with an equal quantity of sodium, 16 gm. ; with potash 

 alone, 2 gm.; and with sodium alone, 2.5 gm. The corresponding yields of barley 

 were 11, 6, 8.6, 4.4, and 2 gin., respectively. 



Among 11 varieties of sugar beets, Elite Kleinwanzleben led with a yield of 

 43,800 kg. of beets per hectare representing a value of 1,059.96 francs. The highest 

 sugar content, 14.8 per cent, was obtained in Kirsche which variety also ranked 

 high in purity. 



Sulphocyanid of potash as a fertilizer interfered with the germination of barley 

 and winter wheat, while the growth of oats seemed to be benefited. Sugar beets 

 also proved very sensitive to this substance. Applying 300 k<_ r . of sulphocyanid of 

 potash and ammonia at planting reduced the yield of sugar beets by 1,800 kg. per 

 hectare; the sugar content, 0.6 per cent; and the quotient of purity by 2.4 as com- 

 pared with results obtained where an equal quantity had been applied a month 

 earlier. Plats receiving barnyard manure together with nitrate of soda at the time 

 of planting yielded 37,000 kg. of sugar beets per hectare with a sugar content of 14.20 

 per cent, while those receiving the manure in March and the nitrate at planting or 

 the manure and part of the nitrate in March and the rest of the nitrate at planting 

 yielded 37,400 kg. with 13.70 per cent of sugar and 38,400 kg. with 14.40 per cent of 

 sugar, respectively. 



The comparative yields of 6 varieties of fodder beets are reported. In the pro- 

 duction of beets, Kirsche stood at the head with a yield of 91,200 kg. per hectare, 

 containing 10.42 per cent of dry matter, while Dauerrunkel, the leading variety in 

 dry matter, containing 14.41 per cent, stood third with a yield of 72,800 kg. 



Equal quantities of seed were planted of 17 varieties of potatoes. The leading 

 varieties, mentioned in the order of productiveness, were Professor Maercker, 

 Up-to-date, Excelsior, and President Kruger. 



A mixture of corn, vetches, peas, and horse beans produced from 20,000 to 28,000 

 kg. of green forage per hectare.
