The present studies have significantly contributed to the methods of the phenological observations on 220 dominant and troublesome weeds of the Tea Gardens of Terai and Hills of Darjeeling district of West Bengal from ±125 m. to ±2010 m and also in in vitro condition. Repeated visit to different tea gardens in different months were made to record the stages of life cycle of different species of plants in the vegetation and a comprehensive phenological calendar were prepared, covering the period from 2017 to 2019. The Tea Garden weeds are mostly Therophytes or Annual herbs and most of them are local species. Different parameters or phenophases used for this study are germination, seedling appearance, vegetative stage, flowering, fruit-set, seed dispersal, death or perennation and modes of pollination which are discussed in this paper.References
