    Abstract
    Phytosociology of weeds were studied in horo rice in haor areas in relation to cultivars and crop growth stages through weed survey. Scirpus juncoides was the most important weed speciaes in all the rice cultivars. Perennial weeds dominated over annuals and broadleaf weeds usually dominated over sedges or grasses. Diversity of species increased with the age of crop plant up to 60 DAT when it declined. 5. juncoides was also the most important weed species at all crop growth stages. At these growth stages perennial weeds dominated over annuals and broadleaf weeds usually over sedges
