years. One fact to be emphasized is that Sunrise kafir has a tendency 
to produce many suckers when the stand is thin, and this character 
is doubtless the' reason why the difference between the yields from 
the different rates is so slight. 
SECOND DIVISION", ROWS SS INCHES APART. 
Table 30 gives the data obtained from Sunrise kafir in rows 88 
inches apart" in the spacing experiments. Five plats were grown 
each year, each plat representing a different rate. With the excep- 
tion of the thick rate in 191s the desired stands were approximated 
in the different rates for the five years.

The number of suckers for each plant increased with the row space 
per plant, as in the rows 44 inches apart. The average number of 
suckers to the plant varied from 0.11 for the thick spacing rate 2) 
in 1921 to 2.55 suckers per plant for the thin spacing (rate 10) in 
1917. One fact to be noted is that with the same number of plants 
to the acre the plants in the rows 44 inches apart average more 
suckers per plant than those in the rows 88 inches apart. On the 
other hand, where the spacing between plants in the rows i- the same
