Resumo: 	ABSTRACT: Chickpea is the third most important crop of rainfed areas of Pakistan, and it is severely affected by noxious weed Asphodelus tenuifolius. Therefore, a field trial was conducted to evaluate the effect of different allelopathic weed extracts, herbicides and mulches in controlling A. tenuifolius and other associated weeds in chickpea at “District Karak” Khyber Pakhtunkhwa-Pakistan. The experiment was carried out in a Randomized Complete Block Design (RCBD) and replicated thrice using a chickpea cultivar (Chattan) which was grown for the experimental trial. There were 9 treatments along with control for comparison. The treatments Stomp 330 EC (Pre-emergence) at 2.5 L ha-1, Fenoxaprop-p-ethyl, Bromoxanil+MCPA (Tank mix), Starane-M, mulching (Eucalyptus leaves), mulching (Wheat straw mulch), allelopathic weed extract (A. tenuifolius) + Stomp, allelopathic weed extract (Cyperus rotundus), allelopathic weed extract (Sorghum halepense) and control treatment were used in this trial. Data were recorded on A. tenuifolius density m-2 before and after application of weed management practices (m-2), A.tenuifolius fresh weight (m-2), seed yield (kg.ha-1), biological yield (kg ha-1) and cost-benefit ratio. Weed density before weed management was found to be non-significant. The data showed that minimum A. tenuifolius density after weed management and fresh weight (m-2) were found for Stomp 330 EC (6.33 m-2 and 1.98 kg m-2), which is statistically similar to Fenoxaprop-p-ethyl 6.9 EC (10.33 m-2 and 3.03 kg m-2) while maximum A. tenuifolius density and fresh weight (m-2) were recorded for control plots (74.33 m-2 and 287.46 kg m-2). Maximum seed yield (1,781.7 kg ha-1), biological yield (3,823 kg ha-1) and cost-benefit ratio (3.47) were recorded for plots treated with Stomp 330 EC, while the lowest seed yield (851.7 kg ha-1), biological yield (3,126.3 kg ha-1) and cost-benefit ratio (1.53) were observed for the control plot. Among the nutritive parameters in chickpea, maximum crude protein (17.40%), crude fat content (4.90%) and oil content (5.98%) were recorded for plots treated with Stomp 330 EC, while minimum crude protein (16.18%), crude fat content (4.12%) and oil content (5.01%) were found in the control plots. Thus, it is recommended that herbicides Stomp 330 EC and Fenoxaprop-p-ethyl should be used at pre-emergence at their recommended doses for control of A.tenuifolius and other associated weeds in chickpea crops.
