RESULTS OBTAINED. 



As these experiments were largely demonstrational, it is of chief 

 importance to consider their economic phases. While more detailed 

 reports of the flower counts, boll counts, branch measurements, etc., 

 would be of interest from the standpoint of a scientific consideration 

 of the factors involved, these data are treated only incidentally in 

 this report. The interest at this time lies in knowing whether 

 single-stalk culture increased the yield of seed cotton, whether it 

 had any effect on the percentage of lint, and whether the quality 

 of the lint was in any way affected. 



YIELDS OF SEED COTTON. 



The experiments are herein discussed by States, in the following 

 order: Louisiana, Arkansas, North Carolina. In presenting the 

 yields of seed cotton obtained, each experiment is first considered in 

 detail, apart from the others. A summary table, bringing together 

 the total yields of all the experiments, is then presented to facilitate 



comparisons. 



Louisiana. 



The nine different experiments conducted in Louisiana, all under 

 boll-weevil conditions, are considered by parishes, as follows: Pointe 

 Coupee, in the south-central part of the State; Madison, in the north- 

 eastern part; Bossier and Caddo, in the northwestern part. 



POINTE COUPEE PARISH. 



Two experiments were conducted in Pointe Coupee Parish, on the 

 farms of Messrs. John Hebert and Alfred Robillard, near Ven tress. 

 They were about a quarter of a mile apart. Both are located on 

 sandy soil, typical of that drained by the Mississippi River in this 

 part of Louisiana, and in each instance the cotton was planted on 

 low beds in rows 4| feet apart. Unfavorable weather influenced 

 both crops early in the season, wet weather during March being 

 followed by drought. 



The Hebert experiment. — Mr. John Hebert planted Sugarloaf cotton 

 on May 10, which was considered unusually late in this section. 

 He planted at the rate of 25 pounds per acre, which was heavier 

 than usual. Germination was good, and an almost ideal stand was 

 secured. Single-stalk culture was compared with the usual method 

 in alternate rows, there being 14 rows of each. 



The old-method rows were thinned on May 25, when the plants, 

 3 to 4 inches high and with 2 to 3 leaves, were spaced about 18 

 inches apart. When the single-stalk rows were thinned on June 6, 

 the plants were 10 to 12 inches high and had 6 to 8 leaves. They were 

 spaced 6 to 10 inches apart. Had the thinning of the single-stalk 

 rows been done a little earlier, it is likely that it would have been
