Abstract: A field experiment was conducted during Boro season of 2002 - 2003 and 2003 - 2004 to study the effect of irrigation and weed management on weed growth and relative yield performance of transplanted hybrid rice. Continuoils submergence of 5±2 cm depth of water considerably reduced the weed crop competition, and increased the grain yield and decreased the dry matter production of total weeds over 3 days after disappearance of ponded water. Hand weeding twice (25 and 45 DAT) and chemical weed control through herbicides are equally effective like weed free plots in reducing population and dry matter of weeds, improving grain yield, besides being significantly superior over unweeded check treatment. An increase in 14.75 to 24.03% grain yield was recorded due to adoption of weed management practices.
