Evaluation of Off-season and Cropping Season Weed Management Practices in Irrigated Cotton

摘要

Cotton has a pride of place among the commercial crops in India as it provides almost 80% of raw material for textile industries in the country Cotton can also be called as "money spinner". The productivity of cotton is 410 kg ha~(-1), which is lowerthan the world average of 595 kg ha~(-1), consisting the necessity for inclusion of better technology for narrowing down the productivity gap, Cotton, being a wide spaced and relatively slow growing crop in early stages, is subjected to a severe weed menace. Weed infestation in commercial crops, particularly in cotton, has been reported to offer severe competition and causing yield reduction to the extent upto 74% in the cotton crop (Shelke and Bhosle, 1990), Continuous use of the same method leads to build up of tolerant weeds. It is, therefore, necessary to combine or integrate two or more methods of weed control, Off-season land management followed by cropping season weed management practices controlled the weeds effectively and economically.
