subject to rot and the latest-ripening varieties least so in 1904 as well as 

 1905. 



In the average for 4 years the following varieties produced the greatest 

 yields at 9 weeks after planting: Early Andes 174, Early Fortunate 170, Six 

 Weeks 169, and Early Dominion 107 bu., and the lowest average yields at the 

 end of the same length of time were produced by Burpee Extra Early, 113, and 

 Stray Beauty. 124 bu. per acre. The results of 11 years of continuous seed 

 potato selection show that in 1905 204 bu. was obtained from large whole 

 potatoes, 183 bu. from medium-sized whole potatoes, 142 bu. from small whole 

 potatoes, and 105 bu. per acre from very small whole potatoes. The percentage 

 of small potatoes in the crops increased as the size of the seed decreased. 



The use of 1 2-oz. potato set in the hill in the average for 6 years gave 211.9 

 bu., 2 1-oz. pieces 203.7 bu.. and 4 i-oz. sets in the hill 1S2.5 bu. per acre. The 

 largest percentage of marketable tubers was secured from the 1 2-oz. set per 

 hill planting. In 6 out of 7 years, planting potato sets 1 ft. apart in the row 

 gave better yields than planting them in squares 33 in. apart each way. The 

 average results for 7 years rather favor hilling than level cultivation. An 

 application of 2 tons of poultry manure per acre gave better yields than the 

 use of smaller or greater quantities, the yield of potatoes being increased by 

 5r> bu. per acre. 



In 1905 the following varieties of swedes ranked first in yield : Rennie Queen 

 22.8. Cropwell. 22.5, Good Luck and Sutton Queen 21.3. and Keepwell 21.1 tons 

 per acre. Thinning the plants at one-half, 2, 5. and 8 in. in height resulted in 

 the best yield from the thinning when the plants were very small. The yield 

 of roots per acre from applications of cow manure and mixed fertilizer was 

 about the same. The average yields with 4 varieties of fall turnips grown for 

 5 years were as follows: Red Top White Globe. 27.9, White Egg 23.1, Early 

 American Purple Top 22.1. and Cow Horn 20.3 tons per acre. 



Among 15 varieties of mangels grown for 5 years Yellow Leviathan stood 

 first with an average yield of 33 tons of roots per acre, being followed by 

 Steele-Briggs Giant Yellow Intermediate, Sutton Mammoth Long Red, and 

 Mammoth Golden Giant. The average yield of tops per acre of the 15 varieties 

 ranged from 2.1 to 6.4 tons per acre. In 3 out of 4 years seed soaked for 12 

 hours gave greater yields per acre than seed not soaked before sowing and that 

 soaked for 24 and 36 hours. 



Notes are also given on experiments with sugar beets and carrots. In experi- 

 ments with varieties of silage corn it was observed that there was a variation 

 from 15.2 to 24.1 tons of total crop per acre between the lowest and the highest- 

 yielding strains of White Cap Yellow Dent, one of the best general purpose 

 varieties for southern Ontario. Deep cultivation immediately after planting, 

 followed by shallower cultivation as the season advanced, produced the largest 

 yield per acre. In general, planting in hills 40 in. apart both ways with 4 plants 

 in each hill, has given better results than planting 10 in. apart in the row. 

 The results with several other forage crops, including sorghum, millet, rape, 

 kale, cabbage, sunflowers, grass and grass mixtures, and a number of leguminous 

 plants are reviewed.

 pp. 30-33). — The different lines of experimental work in progress are briefly 

 described and some of the results obtained are given. 



Fulcaster winter wheat proved one of the best-yielding varieties. Winter 

 wheat, winter barley, and winter oats gave the best results when sown 

 September 30 and winter rye when sown a month later. The yields of these 

 winter crops were as follows: Fulcaster wheat 17 bu., Union barley 32 bu., 

 Culbertson oats 56 bu., and Excelsior rye 26 bu. per acre. Of 25 varieties
