Effect of seedling age on yield and lint quality of cotton



 

ABSTRACT: The study was conducted in the experimental field of the Cotton Research, Training and Seed Multiplication Farm, Sreepur, Gazipur during June 2018 to February 2019 to find out the effective age of cotton seedling for transplanting. Five categories of seedlings viz.,10, 15, 20, 25 and 30 days old were tested along with direct seed sowing as control treatment. Survival rate of the seedlings among the age categories ranges from 79 to 96%. The highest and lowest survival rates of the seedlings were observed in direct seed sowing and 30 days age category seedlings, respectively. The seedling age did not affect yield and yield contributing agronomic traits like plant height and boll weight. Other agronomic traits namely number of plant per hectare, monopodial branch, sympodioal branch and boll per plant among the seedling age categories differed significantly. The highest numbers of monopodial branch and boll per plant were found in control category and the highest number of sympodioal branch per plant was observed in 15 days age category. The seedling age categories had insignificant effect on lint quality characteristics like length, strength and micronaire value of the lint.
