The most frequent, abundant, and dominant weed species were Polygonum nepalense, Guizotia scabra, Galinsoga parviflora, Corrigiola capensis, Plantago lanceolata and Digitaria spp. The average values for frequency and dominance of weeds in wheat ranged between 0.4 to 79.1% and 0.01 to 20.70%, respectively.
