 Cotton culture, R. J. Ket>ding {Georgia Sta. Bui. 31, pp. 389-417). 



Synopsis. — As a result of experiments at the station. King Improved variety, a dis- 

 tance of 1 by 4 ft., 400 lbs. of a complete fertilizer per acre, applying two-thirds 

 of the fertilizer before ]ilaating and one-third with the seed, supei'phosphate 

 instead of Tennessee soft phosphate, and leaving the cotton without topping, 

 are recommended. 



This is a continuation of work published in Bulletin 27 of the 

 station (E. S. E., 6, p. 884). 



Test of varieties (pp. 391-397). — Eighteen varieties were tested. The 

 yield at each picking, number of bolls to the i)ound of seed cotton, 

 number of seeds in 1 lb., yield of lint and seed, percentage of lint, and 

 total value of lint and seed are tabulated. The largest yield of lint 

 (511 lbs. per acre) was made by King Improved, which stood fourth 

 in the yield of seed cotton and seed, thirteenth in size of boll, 

 and second in earliness. In a comparative trial of Jones Improved 

 and King Improved, the latter yielded 1,759 lbs. of seed cotton per 

 acre, surpassing Jones Improved by 108 lbs., and in money value of 

 yield by $6.27 per acre. 



Distance experiments (pp. 397-402). — In rows 4 ft. apart single stalks 

 were left at distances of 1, 2, 3, and 4 ft. During this and the 4 ju'e- 

 vious years, on the manured and unmauured plats, the largest yield 

 was made on the plats planted at distances of 1 by 4 ft. 



The following table gives the yield of seed cotton for different dis- 

 tances for each year of experiment : 



Yield of seed cotton at different distances. 



In an experiment on the distance between rows, Avith a uniform 

 number of plants i)er acre, the largest yield was from the 2-foot rows. 



Effect of increasing amount of fertilizers (pp. 402-405). — In this experi- 

 ment a comidete fertilizer was applied at the rate of 400, 800, and 1,200 

 lbs. per acre and the results compared with those obtained on check 

 plats. With the variety King Improved a profit of 189 per cent was
