Tests of Varieties of Cotton in North far

Tests of Varieties of Cotton in North
 Carolina.
 In last weeks issue was given an ah- stract of the results of experimenIs made with corn at the three branch experiment station farms in North Carolina. In the same publication that contains those results are reports on parallel tests with cotton covering inc subjects of varieties and distance between plants.
 In 1905 twenty three varieties were tested at each of two substations. on sandy soil in the eastern part or the State the varieties yielding the highest combined values of seed and int were in order, Excelsior, Culpepper. Russell Hodge. and Cooks Improved On the red clay soil at a higher altitude in the Piedmont region, the five leading varieties were. in order, King, Hodge Cooks Improved. Culpepper, and Wepp, all these being early or medium in time of maturity.
 An instructive comparison may be drawn from the tables showing the relative yields of two of the most nonular bigboll varieties, Russell and Culpepper At the lower altitude with the long or growing season Russell outclassed Culpepper in four years, while Culpepper was ahead in the other two seasons. At the higher altitude where the season was shorter. the re- suits were just opposite. Culpepper leading in three out of four years. an outcome doubtless due to the greater earliness of this variety Comparing the yields of Toole and Cooks Inn proved. the varieties that stood first in the test at Auburn in 1905, we find that in each of the i've comparisons between these two varieties the ad- vantage was with Cooks Improved which usually stood near the head of the list.
 King and Shine. early varieties that have become the standards in the re- gions infested with the boil weevil. were compared four times and in eacn instance King afforded the larger value of total products. Berry's Big Roll in these tests was notable for an unusual combination of earliness with large size of boll but it's yield was not great. Russell was uniformly more productive than Truitt. even where the season was relatively short and to that extent unfavorable to late variety like Russell.
 The authors note the following as antaRonistic qualities in varieties of cotton. "Q) Earliness in maturity Is not usually conducive to large yields. although in areas where short grow ing period is afforded. the earlier
 
 greater yields (2) Varieties that have large seed generally yield small percentage of lint to seed. (3) Late maturing varieties do not generally produce seed cotton that yields a high percentage of lint although the number Of pounds of lint per acre may be large. (4J Small boiled varieties are not generally easily picked and hence are unpopular with pickers.
 The following were found as as- sociated characters. "G) Varieties that mature early tend to the production of seed cotton that contains a high percentage of lint to seed. t2) Varieties with short staple usually have high percentage of lint and vice versa. (3) Varieties with large bolls generally have large seed and small percentage of lint. C4) The larger the yield of seed cotton per acre. through tRoper fertilization or favorable sea- RO,>sA conditions, the lower the per
