Abstract
TECHNOLOGICAL CIRCULARS NOS. 323 to 338 issued by the Indian Central Cotton Committee's Technological Laboratory during the first three months of 1938 exemplify very thoroughly the work which is being done in India to improve the cotton crop of the country. Each season early samples of the crops from different parts of the country are sent to the Laboratory for test and each circular summarizes the results obtained in the last six years. No. 336 deals, for example, with a pure line strain isolated in 1931 and · grown at the Government Experimental Farm, Akola, where the rainfall is 28 inches per annum, the soil black cotton soil, the growing period from June until November and the maximum temperature varies from 85° to 115° F. ; weight of cotton per seed, 30 milligrams, of seed, 62 mgm. 26 seeds per boll, 16 to 18 bolls per plant ; yield, 400-800 lb. per acre; 43 thousand acres under cultivation as against 120 acres in 1933. The average length of fibre (staple) is inch, the curve of deviation being approximately the error curve. In manufacture, the percentage of loss from dirt is low, that from carding is normal, about 8 per cent. Fibre strength was best in 1933 and then suitable for yarn of 31 counts, that is, 31 hanks of 480 yards to the pound.
