Abstract:

Cotton, popularly known as “King of fibre” and“White gold” is the most important fibre and commercialcrop of India. The contribution of India to global cottonfibre and edible oil production is 44 and 10%,respectively. Though India has the largest area (26%)of cotton in the world, due to its lower productivity theshare to the total world cotton production is only 12%.Weeds consume 5 to 6 times of N, 5 to 12 times of Pand 2 to 5 times of K more than cotton crop and thusreduced the cotton yield from 54 to 85% (Jain et al.1981). Cotton is very sensitive to crop-weed competitiondue to slow growth during early stage and widerspacing.Weed infestation in cotton has been reportedto offer severe competition causing yield reduction toan extent of 74 percent (Shelke and Bhosle, 1990), 50to 85 percent (Sharma, 2008) depending upon thenature and intensity of weeds.
