shows the averages for all dates in all years. The yields also are 

 graphically shown in figure 6. 



FETERITA. 



The agronomic data recorded for feterita in the date-of-seeding 

 experiments are shown in Table VI, and the yields are shown also in 

 Table IX, for comparison with other varieties.

The stands of feterita in general were not as good as those of Dwarf 

 milo. In 1914 the stand in the early-sown plat was only one plant to 

 approximately 53 inches of row space, and in 1919 the plants in the 

 plats sown on early and normal dates averaged 35.2 inches and 63.4 

 inches of row space, respectively. These stands produced suckers to 

 the extent of 75 per cent, which reduced the stalk space to distances 

 ranging from 9 to 16 inches. Even then, however, these plats were 

 not directly comparable with the others in the same years. When 

 there is a large number of suckers, usually some of them are late and 

 do not form heads. These tend to increase the total crop yield, but 

 add nothing to the grain yield. 



There is a wide range in yield from the different dates in the same 

 year and in the different years. The early date made the low yield 

 each year. The normal date made the high yield in two of the six 

 years, while the late-sown plat led in four years. These yields are 

 compared in Table IX and may be seen at a glance in figure 7.
