Abstract |
|
|
|
The use of delinted cotton seeds in cotton planting instead
of fuzzy cotton seeds has spread recently. Cotton planting
area of the world was 32,150,000 ha in 2003 - 2004.
Approximately 45 - 50% of the planting seed in the world is
delinted. This signifies that nearly 16,000,000 ha cotton
area is planted by delinted cotton seed. In this study,
coating fuzzy cotton seeds is proposed as an alternative to
delintation. Coating makes fuzzy cotton seeds more suitable
for the pneumatic spacing planter. Also, unlike delintation,
sulphuric acid is not used for coating and this eliminates
the problems associated with its usage such as seed loss,
pollution and threats to human health. The results show that
the cultivation of coated cotton seeds has no disadvantage
regarding the agronomic and technological characteristics of
cotton seed; coating may even improve the characteristics of
the seeds.
Also, no significant difference exists in terms of yield.
Hence, seed coating has the
potential to expand organic cultivation of cotton, as the
coated seeds can be easily planted with pneumatic spacing
drills and as organic seed procurement would be provided
with the seed coating method.
