Abstract:
This study was carried out
to determine the effect of different boron
application methods on cotton yield, plant
growth and fiber technological properties.
The study was conducted at Siirt
University Faculty of Agriculture
Department of Field Crops experimental
area as randomized complete block design
with four replications in 2018. Stoneville
468 cotton variety and boron liquid foliar
fertilizer were used as material. Seven
different boron applications were
performed as (Control, 1000 cc ha-1 at
pre-flowering stage, 2000 cc ha-1 at preflowering
stage, 1000 cc ha-1 at flowering
stage, 2000 cc ha-1 at flowering stage and
1000 cc ha-1 at boll formation stage,
2000 cc ha-1 at boll formation stage).
The results of statistical analysis showed
that there were significant differences
between applications methods in terms of
plant height and number of monopodial
branches. But there were non-significant
differences in terms of number of
sympodial branches, number of first node
of sympodial branch, number of nodes,
height/node ratio, number of bolls, boll
weight, seed cotton weight of per boll,
number of seeds per boll, first picking
percentage, 100 seeds weight, ginning
percentage, seed cotton yield and fiber
technological characteristics. In conclusion
different application methods of boron
increased plant height and number of
monopodial branches of cotton when
applied as 1000 and 2000 cc ha-1 at preflowering
stages.
