BULLETIN 1374, U. S. DEPARTMElsrT OP AGRICULTURE 



bolls had to be taken into consideration in the counts that year. 

 Frost in 1922, however, did not occur till December 19, and at the 

 time the counts were made that season many nearly mature green 

 bolls were still on the plants. These bolls were recorded at the same 

 time the counts were made, and in this way the figure for ' ' Percentage 

 of crop open" was obtained. The percentage of nonpickable cotton, 

 however, is based on open bolls only. Had the counts been post- 

 poned until after the frost, the amount of nonpicakble cotton would 

 have been greater, for many of the green bolls would have had time 

 to open, and they were all heavily infested. This would not have 

 been comparable with 1921, on account of the lateness of frost. As 

 it was, the results for irrigated cotton are more nearly comparable 

 for the two years, since those in 1922 were made not very long after 

 the time of the year when frost occurred in 1921. The extremely 

 low figure for the unirrigated cotton in 1922 can be partly explained 

 by the earliness of the counts. Had these been made at the end of 

 October the percentage nonpickable would have more nearly ap- 

 proached that of the unirrigated fields in 1921.

1 Zoca fields. "Planta" is planted cotton; "zoca," volunteer cotton. 

 Average nonpickable, all classes, 1921, 12.8 per cent: 1922, 7.97 per cent. 



The great variations shown in the nonpickable cotton on different 

 ranches are due to several things and will be taken up later. One
