DAWN KAFIR. 



Table VII shows the agronomic data for Dawn kafir in the date- 

 of-seeding experiments. The yields are shown also in Table IX and 

 graphically in figure 8. 



Good to fair stands were obtained in most plats in all years during 

 which the experiments were conducted. In most of the plats the 

 row space to the plant ranged from about 5 to 11 inches. A few 

 plats had thinner stands, in one the row space being 26 inches to the 

 plant. On the average the early seeding gave the thinnest stand 

 and the normal seeding the thickest, making a difference of about 3

Fig. 8. — Annual and average yields per acre, in bushels, of Dawn 

 (dwarf) kafir (C. I. No. 340) in the date-of-seeding experiments at 

 the Amarillo Cereal Field Station in the 6-year period from 1914 to 

 1919, inclusive. Horizontal lines show averages for the period. 



inches of row space to the plant. These stands are similar to those 

 of Dwarf milo. 



The vegetative period ranged from 71 days for the late date in 

 1914 to 118 days for the normal date in 1916. The total growing 

 period ranged from 93 days for the normal date in 1917 to 156 days 

 for the early date in 1918. The early date usually required a longer 

 total growing period than either of the other seedings. This was 

 due in part to the slow growth made in the early part of the season 

 while the soil temperatures were low and in part to the large number 

 of suckers, which are usually later than the main stalk. 



The production of suckers varied greatly in the different seedings 

 in the same year and in the same seeding in the different years. In 

 1914 the early seeding produced 49.3 per cent of suckers, and the late 

 seeding produced only 12.6 per cent. In 1915 a large number of
