BULLETIN 1219, U. S. DEPARTMENT OF AGRICULTURE. 
Moisture and temperature conditions in the greenhouse were 
comparable to what would be termed ideal field conditions. The 
experience of large farmers over a period of years covering extensive 
plantings show conclusively that under average field conditions the 
variation between the time required for the germination of ginned and 
closely delinted cottonseed is greater than that shown in the table 
and chart referred to. Under unfavorable field conditions, especially 
where a deficiency of moisture is a factor, the results in favor of 
delinted seed are much more pronounced. 
EFFECT OF DELINTING ON THE PLANTING CAPACITY. 
Delinting increases the planting capacity of cottonseed per unit. 
It reduces the weights of the individual seeds, hence increases the 
number of seeds per unit of weight. The planting capacity per unit

Fig. 3.— Delinting reduces the weight of a given number of cottonseed and increases the number of seeds 
and consequent planting capacity per unit of weight. Such reduction in weight or increase in planting 
capacity is in direct proportion to the quantity of linters removed per ton of seed. 
of weight is increased in the same proportion as the number of seeds 
and the percentage of increase in planting capacity is slightly greater 
than the percentage of reduction in the weights of the individual 
seeds. The reduction in the average weight of the individual seeds 
and the extent to which the number of seeds per unit of weight, and 
consequent planting capacity, is increased at varying rates of delint- 
ing, are shown in Table 5 and are illustrated in Figure 3.
