made in the west end of the May 12 planting because of the very poor 
stand. 
Flower counts were started on June 26 and were made daily until 
July 7. From that time until July 31 they were made every other 
day. The counts from each section of row in each planting are given 
in Table 9, with the total number of flowers counted each day in each 
planting shown graphically in Figure 5. 
The total number of flowers counted on the west end of the rows 
is usually smaller than the number on the east end. This was due 
to retarded plant growth in the west end of the rows caused by 
Johnson grass in that part of the field.

Fic. 5.—Total number of flowers recorded daily from all sections of each cotton planting at San 
Antonio, Tex. 
The flowering of the April 19 and April 28 plantings was delayed 
by the removal of early squares from the plants on June 12, as pre- 
viously stated. Owing to this delay, the first flowers appeared at 
peut the same date in the plantings made on April 19, April 28, and 
ay o. 
The plants in the April 19 and April 28 plantings were larger than 
those in the May 5 planting, however, and produced more flowers 
during the first half of the flowering period. During the period from 
June 26 to July 13, inclusive, the total numbers of flowers counted 
on the respective plantings were 1,966 on the planting of April 19, 
as compared with 1,635 for the planting of April 28 and 1,539 for 
that of May 5 Only 404 flowers were counted during the same 
period on the two 50-foot rows of the M fay 12 planting.

flowers during the first half of the flowering period, ‘the first. three 
plantings reached the peak of flower production on the same: day,
