INOCULATION TEST WITH CLOVER (IRRIGATED). 



That it is necessary to inoculate the land to get the best results with alfalfa in 

 southern Alberta has been quite conclusively demonstrated, so it is not surprising to 

 find that Red Clover requires the same treatment. It might be well to mention, how- 

 ever, that the bacteria that work on the roots of clover are quite distinct from those 

 that live on the roots of alfalfa, so that the soil from an alfalfa field would not be suit- 

 able to use to inoculate land on which Red Clover was to be sown. 



To test the effect of inoculation with Red Clover, three plots of about two square 

 rods each were seeded down without a nurse crop in 1909. The following table gives 

 T,he results of the first cutting in 1910 expressed in yield per acre. By the time the 

 second cutting was ready to be made, no difference in the appearance of the plots could 

 be noticed. The germs had no doubt been distributed by the irrigation water, as the 

 plots were quite small and were adjacent to each other. By the time the second crop 

 was ready, all three plots appeared to be equally good so they were all cut together 

 ?nd yielded at the rate of 2 tons and 750 pounds per acre. 



Inoculation Tests with Clover. 



TIMOTHY (IRRIGATED). 



As yet we have only one plot of one-fourth acre of straight timothy. This was 

 sown in 1908. It was irrigated at the same time as were the mixtures of grasses and 

 alfalfa. It was cut July 13. The yield was at the rate of 2 tons and 140 pounds per 

 acre. 



brome grass (Bromus inermis). 



One-fourth acre of Brome grass was sown in 1908. It was irrigated at the same 

 time that the mixture of grasses and alfalfa were, and was cut July 13. It yielded at 

 the rate of 2 tons and 160 pounds per acre. The second growth would have made 

 excellent pasture, but it was not heavy enough to warrant cutting for hay.
