Abstract
A field experiment entitled, “Yield and quality of cotton genotypes as influenced by different
sowing time”, was conducted at the research area of the Cotton Section, CCS Haryana Agricultural
University, Hisar, during the kharif season of 2017. This experiment comprised of four sowing times
(1st fortnight of April, 2nd fortnight of April, 1st fortnight of May and 2nd fortnight of May) in main plots
and three genotypes (RCH 650, H 1098i and HD 432) in sub-plots. Total thirty six treatment
combinations were tested in split plot design with three replications. The crop sown on 2nd fortnight of
April gave significantly higher seed cotton yield (4556 kg/ha) than the other three sowing times, it was
mainly attributed to more plant height, dry matter production, leaf area index, no. of bolls/m2, no. of
sympodial branch and boll weight. Sowing time have shown non-significant effect on fiber quality
parameters such as micronaire value, fiber strength, span length and upper half mean length (UHML)
because these parameters are genetically controlled and therefore less influenced by sowing time.
Among the three genotypes, RCH 650 produced significantly higher seed cotton yield (4395 kg/ha)
than the genotype H 1098i (3344 kg/ha) and HD 432 (2488 kg/ha). More dry matter production, leaf
area index, no. of sympodial branch and boll weight might have accounted for the highest seed cotton
yield of genotype RCH 650. The difference in seed cotton yield among the genotypes might be due to
different genetic characteristics of these three cotton genotypes. Genotype RCH 650 has shown better
fibre quality traits such as micronaire value (4.42 10-6g/inch), fiber strength (28.21 g/tex), span length
(82.41 mm) and UHML (27.67 mm) than the genotypes H 1098i and HD 432. Genotype HD 432
produced higher seed cotton yield when sown on 1st fortnight of April and H1098i produced higher
seed cotton yield during 1st fortnight of April and 2nd fortnight of April.
