section. In these the highest average yield, about 15 bushels per 

 acre, has been obtained at Redfield. The average yields at Moccasin 

 range from 8 to 12 bushels per acre; at Havre, 4 to 6 bushels per acre: 

 at Sheridan, 2\ to 3 bushels per acre; and at Dickinson, 12 to 14 

 bushels per acre. At all these stations the Kaiser has given the 

 highest average yield of s.eed. At Edgeley held peas have given very 

 satisfactory results as pasture for hogs. 



FIELD PEAS WITH GRAIN MIXTURE. 



The practice of sowing a mixture of field peas and one of the small 

 grains for forage is common in some parts of the country. Tests 

 have been conducted at Havre and Moccasin for several years to 

 determine whether this practice has any advantages over peas sown 

 alone. The results are shown in Table 21. At Havre the results 

 favor sowing the peas alone, but at Moccasin the difference is in favor 

 of the mixture. The difference between barley and oats in the 

 mixture with the field peas is not enough to be significant.

 and Moccasin in stated years.

SOY BEANS. 



As a result of the introduction and development of shorter season 

 varieties of soy beans, the crop has increased in popularity during the 

 last few years (fig. 16). This interest has extended to the eastern 

 part of North Dakota, South Dakota, and Nebraska. However, 

 they have not as yet given promise of being of any great value in most 

 of the region under consideration, as they do not appear to be sulli- 

 ciently drought resistant to produce prod table yields where the 

 rainfall is much less than 20 inches. While soy beans have produced 

 fairly good seed yields at Redfield, S. Dak., the average production 

 for a period of years is loss than that of wheat. Because of this ii 

 would be necessary for them to bring a considerably higher price per 

 bushel to offset the smaller yield, if they are to compete successfully 

 with wheat as a grain crop. As a forage 4 crop at Redfield they have 

 QOl proved at all successful when sown broadcast, and in rows they 

 can not compete with alfalfa and sweet clover from the standpoint of 

 yield. Furthermore, they are a more expensive crop to produce. 



In t he extreme eastern part of this region soy beans are occasionally 

 planted in corn for silage. For this purpose the Manchu variet\ i-
