to 1915, inclusive, because of the minor importance of the crop, the 

 proso varieties were grown only in rows. These rows usually were 

 60 feet long and replicated two or three times. During this period 

 the highest average yields were obtained from the Turghai and Eed 

 Russian varieties. 



In 1916 a few of the leading varieties of proso from the nursery 

 row experiments were sown in plats. These were continued for 

 three years more and several additional varieties also were grown in 

 1917 and 1919. The Dakota Kursk, a millet of the foxtail group, 

 was included in both the nursery and plat experiments for compari- 

 son with the prosos. The yields of the varieties are shown in 

 Table XXV.

As shown in Table XXXVI, the Eed Russian variety produced the 

 highest average jdeld during the 4-3'ear period. The TVhite Ural, 

 the next highest jnelding variety, produced 3.4 bushels per acre less 

 than Eed Russian. Both the Black Voronezh and the Hansen yielded 

 less than the White Ural. The Turghai was the highest yielding 

 variety in the nursery experiments, but it did not yield as well as 

 Red Russian in the plat experiments. It was not grown in plats 

 in 1918, however. 



Average agronomic data for the proso varieties grown in 1917 and 

 1919 are shown in Table XXVI.
