General
- Cotton is a
subtropical, perennial plant with an indeterminate growth habit.
Vegetative and reproductive development occurs simultaneously. While
vegetative growth is necessary to support reproductive growth,
excessive vegetative growth can be detrimental. Under excessive
vegetative growth, fruit abortion may increase, crop maturity may be
delayed, and harvest reduced. Growth habits of cotton varieties are
inconsistent, with many characterized by their tendency for aggressive
vegetative growth.
- The growth habit
of these varieties combined with exposure to high availability of
nutrients, timely rainfall or irrigation, and delayed fruit retention
can encourage excessive vegetative growth. Cotton plants produce
several natural growth regulators or plant hormones, which modify
plant growth and divert energy allocation within the plant.
Ginning Of
Cotton
-
Cotton
ginning is seasonal. It begins with the maturing of the cotton crop,
which varies by region, and ends when the crop is finished. Each year
the cotton ginning season starts in the lower Southwest region in
midsummer, continues through the south central and other geographical
regions in late summer and early autumn, and ends in the upper
Southwest region in late autumn and early winter.
-
Cotton
is subjected to three basic conditioning processes--drying, cleaning,
and extracting--before it is processed for separation of lint and
seed. To ensure adequate conditioning, cotton gins typically use two
conditioning systems (drying, cleaning, and extracting) in
series.
-
The
role of the cotton gin has changed dramatically in the last 50 years
to keep up with technological and production changes in the cotton
industry. At one time, the gin's only function was to remove
cottonseed from the fiber. Today, gins must not only separate the seed
from the fiber, they must also dry and clean the fiber and package it
into bales before it reaches the textile mill.
Applications Of Surgical
Cotton
-
Surgical
Cotton also known as absorbent cotton wool or purified cotton is used
at large in surgery as a dressing material for burns & wounds as a
cotton bedding for maintaining a uniform temperature in inflamed parts
and therefore finds applications in Hospitals, Dispensaries, Nursing
homes, etc.
Market
-
Cotton,
the most important fibre crop of India plays a dominant role in its
agrarian and industrial economy. It is the backbone of our textile
industry, accounting for 70% of total fibre consumption in textile
sector, and 38% of the country's export, fetching over Rs. 42,000
crores. Area under cotton cultivation in India (8.9 million ha) is the
highest in the world, i.e., 25% of the world area and employs seven
million people for their living.
-
Cotton
productivity in India is quite low as compared to world standards. The
modern cotton production technology relies heavily on the use of
fertilisers and on chemicals to control insect pests, diseases, weeds
and growth regulators. Cotton cultivated on 5% cultivable land
consumes 54% of total pesticides used in Indian agriculture, and in
some pockets, the rates are higher than this, leaving immense
ecological and human hazards as reported by World Health Organisation.
