SUPPRESIVE CAPABILITY OF HERBICIDES AND PLANT EXTRACTS AGAINST CHICKPEA WEEDS

The effect of different herbicides (pre-emergence and post emergence) and two plants water extracts (Parthenium and Eucalyptus) on weeds and yield of chickpea was evaluated in a field trial at Agricultural Research Station Ahmad Wala, Karak, Khyber Pakhtunkhwa Province of Pakistan, during rabi season of 2010-11. Isoproturon 500 EW was very effective in controlling the weeds and reduced the weed density (98 m-2) significantly as compared to control (368.3 m -2). Moreover, significantly highest plant height 56.77cm each was recorded for both Parthenium and Eucalyptus extracts. Maximum 100 seed weight of 20.25 g was recorded in Isoproturon 500 EW treated plots followed by Eucalyptus extract that gave 19.25 g. Further results revealed that maximum biological yield (4000 kg ha-1) was recorded under Partheniumtreated plots, while the weedy check produced significantly lower biological yield (2500 kg ha-1).
