It will be observed that Smyrna oats was replaced by Texas for 

 the reason previously mentioned that the former does not make a good 

 hay. 



Two rotation experiments in a range in which wheat is grown 

 every third year, and is followed by two crops of oats for hay in one 

 case and two crops of a mixture of oats and vetches in the other, 

 furnish comparative results in respect of the hay produced. 



These results are given in Table VII hereunder. 



Table VII. 

 Hay Yields. 



There were five plots under each treatment, >o that the results in 

 each case are averages of five plots. 



In both the years 1918 and 1919 the same plots carried the same 

 crops. In 1920 the whole range will again carry wheat. The 

 rotation for the two halves of the range will be : —

As regards the actual yield of hay, oats alone gave a higher yield 

 in 1918 than oats and vetch, but in the following year the position 

 was reversed. The oats in the oats and vetch plots appeared more 

 vigorous during the period of growth in 1919 than that in the plots 

 under oats alone. 



The feeding value of oat and vetch hay is far superior to that of 

 oats alone. Stock also prefer the mixed hay. Although there is 

 more work involved in the curing of the mixed hav (this applies to 

 all legumes), yet the farmer is well compensated for the extra trouble 

 and expense involved in the higher feeding value of the hay produced. 



Vetch hay, whether it be the hairy, spring, or French winter 

 variety is greatly relished by stock, and in protein content it stands 

 on a level with lucerne hay. An oats and vetch mixture makes good 

 ensilage. The crop should, however, be cut when the oats are in the 

 dough stage if possible. For ensilage a mixture of 50 lb. Smyrna 

 oats and 20 lb. spring vetch or French winter ""an be recommended. 

 Such a crop should be sown early so that it can be cut and put into
