  • This experiment was conducted to know the difference in weed population in the five cropping patterns kept same for six years from 1976 such as ricebarley, potato-rice, pea-rice, rice-rye, and rice-fallow. More and many weeds were growing in single cropping field than double cropping field. Dominant weed species in pea-rice and potato-rice cropping patterns were M. vaginalis and S. hotarui, M. vaginalis and P. distinctus. Coefficient of similarity of the cropping patterns between pea-rice and potato-rice appeared higher than single cropping system. However, pea-rice and rice-fallow cropping patterns showed low coefficient of similarity.
