EFFECT OF DIFFERENT SEEDING DATES ON MORPHOLOGY AND YIELD OF DIFFERENT COTTON GENOTYPES

Abstract

The experiment was conducted at Cotton Research, Training and Seed Multiplication Farm, Sreepur, Gazipur during May 2006 to January 2007. The experiment was carried out to determine the appropriate sowing time of cotton. Twenty two genotypes of cotton were tested. The genotypes were planted in three different sowing dates viz. May 15, Junel5 and July 15. Among 22 genotypes five genotypes (NAM-77, C-2602, BC-0342, BC-0406 and CB-I 0) were found to be short durated in respect of early flowering (57, 57.67, 57.74, 58.87 and 57.29 days in June sowing respectively) and boll splitting time (9432, 87.19, 100.56, 102.67 and 95.56 days in June sowing) than the cultivated genotype CB-9 (68.33 and 130.41 days for first flowering and first boll splitting respectively)
