Yields of uiixtures of oats, rye, and vetches were very 

 low and are not given in the table. Similarly, mixtures of gluyas 

 and Union wheats with vetches gave low yields and a poor hay in 

 each case. The inclusion of wheat in these experiments was dis- 

 continued in the following seasons. 



The hay produced from either Cape barley or rye with vetches 

 was not readily eaten by stock, so that these crops were also omitted 

 from the hay mixtures after 1917. 



From a study of the above results it will be .seen that the sowing 

 of greater quantities of vetch seed than 20 lb. to the acre were not 

 justified in oat and vetch mixtures.

Yields marked * are averages of two plots. 



Peas were found to give an impalatable hay, and moreover the 

 crop proved too early for any of the varieties of oats grown. The 

 growing- of peas was in consequence discontinued in these experi- 

 ments. 



Although Smyrna oats and spring vetch have given a slightly 

 better return of hay to the acre than Algerian oats and hairy vetch, 

 yet the Smyrna oat cannot be recommended for the purpose of hay, 

 as it yields relatively coarse fodder. 



Where a mixture of oats and vetch is to be ^lown for silage the 

 Smyrna variety could with advantage be grown with a variety of 

 vetch ; since it is about fourteen days earlier maturing than Algerian 

 oats, spring or French winter vetch should be chosen in preference 

 to hairy vetch. 



At this stage of the experiment it was concluded that not less 

 than 50 lb. of oat seed to the acre should be sown along with vetches 

 in order to obtain maximum yields of hay.

* These yields are average's for five plots in each case and represent, therefore, good standards 

 of comparison of the various combinations of cereal and vetch.
