Floristic and phytosociological studies of weeds in wheat crop fields of Mungeli district of Chhattisgarh, India

The field study was carried out to examine the floristic diversity of weeds in wheat crop fields during the Rabi season of 2018-2020 in four villages, Barela, Semarchua, Chamari, and Karhi, of Mungeli district in Chhattisgarh (India). This study recognized the floristic composition of weed species and evaluated the most dominant and common weeds at the study area. 48 weed species belonging to 19 families were recorded in all the study sites of wheat crop fields. The maximum numbers of weeds were observed in village Barela (46) followed by villages Semarchua (45), Chamari (41), and Karhi (36). The floristic composition of weed species was recorded as dicot (16%), monocot (79%), and pteridophytic (05%) groups. According to the highest importance value index (IVI value), Alternanthera sessilis (L.) DC was found to be the most dominant weed species in the wheat crop fields of village Barela, followed by Anagallis arvensis L., Medicago polymorpha L., and Chenopodium album L. in Karhi, Semarchua, and Chamari villages, respectively. This survey will provide basic information about weed flora.
