EXPERIMENTAL FARMS 



1-2 EDWARD VII., A. 1902 

 SUMMER-FALLOW COMPARED WITH UNPLOUGHED STUBBLE. 



This year the difference in favour of summer-fallow is less than usual, no doubt 

 owing to the rank growth on the latter. The stubble land had only borne one crop 

 since it was summer-fallowed. 



The size of plots used for this test was one-fortieth of an acre, and the soil was 

 a sandy loam. Both plots were sown on May 15. 



A TEST OF FERTILIZERS FOR THE GROWING OF WHEAT. 



Unlike last year's experience with this test, the conditions were quite favourable. 

 A shower followed directly after the spreading of the fertilizers, and they were at 

 once washed into the soil and the wind had no opportunity to blow them away. 



From the accompanying tables it will be noticed that the plants treated with 

 nitrate of soda have given the best returns. 



The size of the plots was one-fortieth acre, the soil was a rich clay loam which 

 had been summer-fallowed. All were sown on May 10, and all were harvested on Aug- 

 ust 23. 



The variety of wheat sown on all the plots was Red Fife, one and one-half bushels 

 of seed per acre. 



Red Fife Wheat, Fertilizers Applied. 



100 lbs. per acre of nitrate of soda, i sprinkled 

 when the grain was 2 in. high, balance when

SELECTED AND UNSELECTED SEED. 



During the harvest season of 1900, the largest heads were selected from the stand- 

 ing grain of thirty-four varieties of wheat and six of barley. The seed was sown this 

 year for a comparison with unselected seed from the same plots. 



The plots were all the same size, viz., 1-20 acre, and each pair was sown in close 

 proximity. The accompanying tables give the result of each individual variety and 

 also a summary which shows great variation in the returns, the average, however, 

 shows that the unselected wheat yielded 9 pounds per acre more than the selected, and 

 the selected barley 1 bushel 32 pounds per acre more than the unselected.
