The phenology study in Lamb’s quarters (Chenopodium album L.) revealed that the spike initiation starte d from 35 days after sowing (DAS) and completed at 40 DAS. Th e flowering period initiated at 43 DAS and reached 50 per cent at 54 DAS and completed at 65 DAS. Seed development a nd maturation results showed that the seed takes abo ut 45 days to attain its physiological maturity from the anthe sis. Eight different stages of seed development were observed based on the changes in seed colour. Therefore, seed was grey ed brown (RHS N199A)in colour and possess 12.7 per ce nt moisture content at the time of seed maturation. Also the max imum seed fresh weight (2.20mg seed ) and dry weight (1.55mg seed -
