Abstract
To achieve self-sufficiency in good production, cotton should be grown after barley in the southern part of Korea. But, this cropping system reduces cotton yields and fiber qualities in the current leading cotton varieties because of the short frost-free growth period. Ethrel-treated plots shortened the time to open boll by about 20days, increased the percentage of open bolls before the first frost from 38% to 93% and increased yield by 15-38%. There are not significant differences in staple length, tensile strength of the fiber, single bollweight, 100 seeds weight and germination percentage of the seeds between Ethrel-treated and untreated plots. Ethrel should be recommended to the farmers growing cotton after barley harvest.
