| dc.description | The word "Qutum or kutum" has given rise to the English word "Cotton". The sanskrit
words kurpasa and karpasum denotes cotton (Watt, 1907). Cotton, a major agricultural
crop, is growing more than 60 countries of the world providing employment and income
to the millions of people. Bangladesh has a glorious historical reference to growing
superfine quality of cotton. The world famous "muslin" was greeted in every part of the
earth. After independence 1972, a comprehensive development program was taken in the
country. Now it meets 6-8% of our national demand but has enough feasibility to grow
more. It is a multipurpose crop and raw materials for the industry. There are 152 yarn
and textile mills in Bangladesh. Every year 6,00,000 to 7,00,000 bales of medium and
long staple cotton fibre are used in these mills, but our production is only 75,000 to
90,000 bales, maximum cotton is imported from abroad at the expense of costly foreign
currency (Anon, 2001) | en_US |
| dc.description.abstract | Study with the different varieties of cotton and its pests indicate that the varieties having
dense hairs and trichoms e.g. CB-9 and CB-5 are more tolerant to sucking pest’s rather
smooth varieties. But, bollworms and whiteflies have the positive co-relation with the
hairs. The serrated leaved variety SR-05 is potential enough for its less canopy volume
and well ventilated bottom environment. More over, a positive relation of predators is
found with the abundance of preys. Variety with desirable plant height, number of bolls,
boll size and individual boll weight plays an important role for substantial economic
return. | en_US |
