The present study was conducted to determine the diversity of weed species in wheat fields of the district Rajouri (J&K) For analyzing diversity20 quadratsof (1m.×1m.) wererandomlylaid down in each block. In everyset ofquadratfrequency, density and abundance was observed throughout the cropping season and IVI (Important value index) was determined. During the course of field study it was reported that the maximum infestation was shown by grassy weed Avena fatua having maximum density (10.15, 12.12, 7.30, 9.35, 10.6, 8.55 from site 1–6 respectively) and IVI (35.71, 43.49, 30.27, 33.91, 32.59, 32.11 from site 1–6 respectively) in all the selected sites. While the least dominant weeds were Calotropis procera, Conyza japonica, Cannabis sativa, Rumex acetosa, Euphorbia prolifera and Sonchus asper etc. A total of 116 weed species belonging to 3 monocot and 27dicot families were reported from the target site.
