CIKCULAR NO. 123, BUREAU OF PLANT INDUSTRY. 



These experimental plantin<2;s by farmers were made under the 

 supervision of Mr. Ar^yk> McLachhvn and Mr. E. W. Hudson, both of 

 the Bureau of Phxnt Industry, Mr. Hudson devotin^]: his attention 

 chiefly to the work in the wSalt River Valley. 



ACREAGE AND YIELDS. 



Owino: to various causes, a portion of the acreapje planted to 

 Egyptian cotton failed to produce a crop. Among these causes 

 was the lack of irrigation water for some of the fields, while the soil 

 in other fields was too salty, and in one section high ground water, 

 resulting from a flood in the Colorado River, killed the crop in mid- 

 summer. About 480 acres came through the season to harvest. 

 From this acreage 375 bales of about 500 pounds each were finally 

 picked and ginned. Of the total number of bales 262 were ginned 

 in the Salt River Valley, 17 in the vicinity of Bard, Cal., and 96 in 

 the Imperial Valley. These figures do not include 24 bales produced 

 on the experiment farms at Sacaton, Ariz., and Bard, Cal. 



The yields from different fields varied greatly. Many of the 

 farmers who planted cotton were not familiar with the requirements 

 of the crop, and some fields were given very little attention after 

 planting. The average yield of lint per acre, determined from the 

 total quantity of lint known to have been picked and baled and 

 the total number of acres upon which this cotton was produced, 

 was approximately 400 pounds. The acreage upon which this 

 computation is based included, however, much land on which the 

 crop was very light. 



A number of fields were measured during the season, and records 

 were kept of the crop harvested. The yields determined from 

 fields in the Salt River Vallev are given in Table I.
