Abstract:

The quantitative survey of four selected irrigated farms namely; student`s Farm, Malir Farm, Latif Farm of Sindh Agriculture University Tando Jam and experimental fields of wheat Research Station. Tando Jam was carried out to determine the weed spectrum during the year 1996-7. In all twenty six weed species were collected, pressed, dried, preserved and poisoned with mercuric chloride and mounted on sheets. Most density populated as well as most frequently occurring weed was common lambsquarters (Chenopodium album). Its frequency was 30% and relative density was 13.53%. Whereas Heliotropium europacum L. was observed with least population density (0.52) as well as least frequently (3.33 %) occurring weed.
