these plantings. During the period from July 13 to July 31, the date 

 when flowering practically ceased, the May 5 planting produced the 

 largest number of flowers relative to the number of plants, while the 

 April 19 planting produced the smallest number. The total number of 

 flowers counted during the entire season was nearly the same in each 

 of the first three plantings, being, respectively, 2,606 for the April 19 

 planting, 2,517 for the April 28 planting, and 2,620 for the May 5 

 planting. On the two 50-foot rows of the May 12 planting 866 

 flowers were counted. The small number of flowers produced on 

 these rows was due to the very irregular stand of plants.

 in successive plantings at San Antonio during the period from June 26 to July

Most of the flowers produced after the middle of July were shed as 

 a result of adverse climatic conditions. The ability of late-planted 

 cotton to continue flowering under severe conditions is to be noted, 

 however. This probably was connected with the continued produc- 

 tion of interhodes on the lower fruiting branches of the late-planted 

 cotton, which occurred both at San Antonio and at Charleston. 



SHEDDING OF BOLLS IN EARLY AND LATE PLANTINGS 



As a result of dry weather considerable shedding of bolls occurred 

 in the different plantings. In order to compare the extent of boll 

 shedding in these plantings, the numbers of shed bolls were recorded 

 from the 50-foot sections of rows on which the flower counts were 

 obtained. These counts do not represent the total number of bolls,
