Chickpea (Cicer arietinum) is the most important crop sustaining the economy of district Karak, Pakistan. Weeds cause enormous losses to the quantity as well as quality of the crop. A survey was launched during February 2004, to record the phytosociological status of chickpea farms. A total of 21 chickpea growers from seven villages in district Karak, Pakistan, were randomly selected. At each farm, the density of weeds was determined using standard quadrate method. The density data were subjected to analysis to compute Relative density (%), Frequency (%), Relative frequency (%) and Importance value. Asphodelus tenuifolius emerged as the predominant species in the district. The highest importance value of A. tenuifolius weed was recorded (88.6) in Hada followed by Wachobaqas (65.2) and Bogara (64.8). Whereas, the highest (38.6) importance value of Medicago denticulata was observed in Lakki Ghundaki and Ahmad Wala (32.8). Medicago-Cynodon-Asphodelus community was recognized at Ahmad Wala, Medicago-Fumaria- Asphodelus was prevalent in Ambiri Kala, and Medicago-Asphodelus-Cynodon existed at Lakki Ghundaki and Asphodelus-Cynodon-Euphorbia commenced at Wachobagas. At Bagara, Hada and * Correspondence to: G. Hassan, E-mail: hassanpk_2000pk@yahoo.com H. Hassan et al. 70 Sarkhawa the communities predominant were Ashphodelus-Cynodon-Euphorbia, Asphodelus-Cynodon and Asphodelus-Medicago-Cynodon. Asphodelus, Medicago, and Cynodon in the decreasing order were the major weeds in chickpea farms of Karak.
