EXPERIMENTAL FARMS 



4 GEORGE V., A. 1914 



The above tabic would seem to indicate that no results are gained from discing 

 alfalfa. 



RATES OF SEED PER ACRE. 



The following fields were sown in the spring of 1911 on land on which grain 

 was grown the year previous. They were irrigated once on June 13. Only two 

 cuttings were made, viz., the first on July 3 and the second on August 15. Size of 

 plots, I acre. 



GRASSES AND MIXTURES. 



A plot of one-quarter acre of Timothy was cut July IS, and yielded at the rate 

 of 1 ton 1,400 pounds per acre. A plot of one-half acre of Brome grass was cut July 

 IS, and yielded at the rate of 3 tons 30 pounds per acre. A plot of one-half acre of 

 Western Rye grass, cut July 18, yielded at the rate of 1 ton 1,400 pounds per acre. 

 A plot of -92 acres of Clover and Timothy mixed, gave two cuttings, one on July 15 

 and the other September 10, the two cuttings giving a yield at the rate of 3 tons 

 1.413 pounds per acre. 



IRRIGATION OF HAY. 



It has been found that to get the best returns with hay under irrigation it should 

 be irrigated thoroughly in the fall. The advantage of fall irrigation is that the land 

 is in a moist condition in the spring, which gives the hay a good, vigorous start 

 quite early; and if the water is not turned into the ditches until rather late in the 

 season, as is often the case, the crop does not receive as serious a cheek as would 

 otherwise be the case. 



The advantage of fall irrigation applies to alfalfa, and still more particularly 

 to the grasses. With fall irrigation a deep-rooted crop, like alfalfa, will, in an 

 ordinary season, give a maximum yield at the first cutting without again being 

 irrigated in the spring, but with such shallow-rooted crops as Timothy and Brome 

 grass, etc., it is necessary to irrigate in May, and often two or three times before 

 cutting time.
