The experiment was repeated in 1912 on field A-III. The results 

 are shown in Table V.

Fig. 3.— Red clover on plat A-II-S, photographed June 13, 1912. This was planted in 1911, and yielded 



at the rate of 3.7S tons per acre in 1912. 



Table V shows that early planting resulted in higher yields than 

 those from late planting, as was the case on field A-IV in both 1911 

 and 1912. The row planting yielded even less favorably on field 

 A-III than it did on field A-IV. 



All the results so far obtained favor early planting. They oppose 

 planting in rows where irrigation is practiced and where the crop is 

 cut for hay. Further time is required to determine the fuial influence 

 of the nurse crop. 



GRASS MIXTURES. 



While it is recognized that alfalfa is likely to remain the leading 

 forage crop of the })roject, information is often desired as to the 

 value of other forage plants, especially grasses, clovers, and grass 

 mixtures. Such information will be ])articularly useful to farmers 

 who expect to engage in dairying and wh<^ will therefore have need 

 for cow pastures during a part of the j'car. In 1911 and 1912 an 

 experiment in which grasses and clovers (fig. 3) were tested singly 

 and in difl'erent combinations was conducted in cooperation with the
