      Dr. Ashim Chakravorty , Dr. P.D. Ghosh
Abstract: The present paper deals with the phenological study on broad leaved kharif weeds of randomly selected fifty one species of angiosperms from the agricultural farm of Zonal Adaptive Research Station, Krishnagar, Nadia and different blocks and village area like Bhaluka, Nabadwip and other adjoining areas of Krishnagar, Nadia, West Bengal during June 2008 to May 2011. The emergence of weeds took place from June to September showing early arrival in case of Amaranthus spinosus, Croton bonplandianum and Jatropa multifida and late arrival in case of Aerva lenata, Utricularia bifida and Wahlenbergia marginata. Initiation of flower bud blooming was early in Evolvulous, Bacopa, Hydrilla and Bromus while late emerging weeds had late initiation of floral buds and blooming. The earliest commencement of fruiting was in July in E. alsinoides while it was as late as December in seven species. Percentage of dicotyledonous plants was more than that of the monocots. Most of the members are edible and have more or less good local medicinal uses in the village areas. A good number of weeds belonging to the families which are prevalent in this alluvial zone are Amaranthaceae, Rubiaceae, Liguminaceae, Pappilionaceae, Solanaceae, Malvaceae, Labiateae, Scophularaceae and Compositeae.
