Cotton
fiber color is determined by the effect of fiber reflectance (Rd) and fiber
yellowness (+ b), which are important standards for determining cotton price.
This study was conducted to determine effects of different sowing times on
fiber color components in widely grown four cotton varieties in 2015 and 2016
under Harran Plain double crop conditions. The
experiments were conducted on the experimental area of Agricultural Faculty of
Harran University at Eyyubiye Campus. Seeds of cotton cultivars were sown
according to sowing dates with completely randomized split plot experimental
design with three replications. Sowing dates (June 1st, June
10th , and June 20th) were kept
in main plot and varieties (Stoneville 468, BA 119, DP 499 and PG 2018) were in sub plot. Four cotton varieties (Stoneville 468,
BA 119, DP 499 and PG 2018), which are certified for Harran Plain, were used as
plant material. As the result of the
study, the fiber color of Şanlıurfa province, where all varieties are in
the light and white class according to the HVI color scale, but white color is
changing from standard 2 to standard 3 and standard 4 grade. All the varieties used in the experiment were
affected by sowing time in terms of fiber color and whiteness of color was
found to be dulled with the delay in the sowing time. For this reason, early
and late harvests should not be mixed and should be stored separately.
