of the size of the pieces and of the decrease in the distance between the 

 pieces in the row; thus, the highest average yield (177.6 bus.) was 

 produced by the two ounce pieces planted one foot apart in the row, and 

 the lowest yield per acre {107.3 bus.) was produced by the one ounce 

 pieces planted two feet apart in the row. 



Selection of Seed. For ten years in succession, large, medium- 

 sized, small, and very small potatoes have been selected continuously 

 and planted from season to season. The crop of 1904 shows, that as 

 the seed decreased in size not only was there a decrease in the yield of 

 potatoes per acre, but there was an increase in the percentage of small 

 tubers. 



Planting One, Two, and Four Potato Sets per Hill. For five 

 years in succession, an experiment has been conducted by planting one, 

 two, and four pieces of potatoes per hill, using the same amount of 

 seed throughout. The average results for the five years are as fol- 

 lows : One two-ounce piece in a hill, 195.2 bushels; two one-ounce 

 pieces in a hill, 182.9 bushels; and four one-half ounce pieces in a hill, 

 162.4 bushels per acre. The cutting of a potato tends to increase the 

 number of stems produced, and when from two to four potato sets are 

 planted in one place there is a greater number of stems produced than 

 where one large piece in used. Evidently a few large, vigorous stems 

 give better results than a large number of small, weakly stems, 

 which are almost sure to grow where more than one piece is planted 

 in each hill. 



Methods of Planting Potatoes. Some farmers favor planting 

 potatoes in rows 25 to 30 inches apart; while others favor planting in 

 squares, or hills, from 30 to 40 inches apart both ways. An experiment 

 has been conducted in our experimental grounds for seven years in suc- 

 cession, in order to compare the results of planting potatoes in rows 

 three and a third links (26 2-5 inches) apart and having the potato sets 

 one foot apart in the row in comparison with planting the potato sets 

 in squares 33 inches apart both ways. The same amount of seed was 

 used in each method, and the experiment was conducted in duplicate 

 each year. The average results for seven years show, that the pota- 

 toes which were planted in rows gave 179.6 bushels, and those planted 

 in squares gave 152.3 bushels per acre. 



Corn foe, Fodder and for the Silo. 



There has not been much variation in the area devoted to fodder 

 and silage corn in Ontario within the last ^w years. The average for 

 the last two years, however, is about nineteen per cent, greater than 

 for the past twenty-three years. 



Varieties. It should be quite evident to a person familiar with 

 the growth of fodder and silage corn throughout Ontario that no one 

 variety is equally suited to all parts of the Province. It is also a fact 

 that some of the varieties which give the best results in the middle
