ABSTRACT
A survey was carried out to determine the major factors influencing chickpea productivity. Weeds may be one of the main causes of low productivity in Pakistan. In order to highlight the most significant and challenging weeds of the chickpea crop in the southern regions of Khyber Pakhtunkhwa, Pakistan, during the Rabi season 2022. Five chickpea growing regions were selected in chickpea growing area of district Karak. The quadrate method was used to determine the relative weed density. The data were recorded on density (%), relative density (%), frequency (%), relative frequency (%) and importance value of weed species. The present findings revealed that Asphodelus tenuifolius Cav., Carthamus oxycantha M. Bieb., Medicago denticulata Willd., Anagallis arvensis, Lathyrus aphaca L. Euphorbia helioscopia L., Convolvulus arvensis L., Cyprus rotundus, Vicia sativa L. Ehrh., Cynodon dactylon L. Pers. and Fumaria indica Hausskn were all found in five locations around the district. The main species in the district emerged as A. tenuifolius Cav. The highest relative weed density (64.2%) and relative weed frequency (45.2%), respectively was noted for A. tenuifolius Cav. While, the lowest value of relative weed density (3.5%) and relative weed frequency (1.2%), respectively was documented for E. helioscopia L. A good judgement for determining the status of a particular weed in a community is the assessment of importance value of the weed species. The data showed that the highest importance value (55.7%) was considered for A. tenuifolius Cav. While, the minimum importance value (3.2%) was noted for E. helioscopia L. Thus, farmers and the scientific community found the information from this study to be extremely helpful in developing a strong integrated weed management plan for the chickpea crop in District Karak.
