The study on phyto-sociological association of weeds in winter crops viz., brown sarson (Brassica campestris L.), oat and wheat (Triticum aestivum L.) of Kashmir valley was conducted during 2000–01 and 2001–02 at varying altitudes from 1500 to 2000 MSL. Maximum IVI of Poa annua was noticed in brown sarson (throughout valley) and oat (only in higher belts >1700 MSL). At lower and mid altitudes in oat fields and at high altitudes in wheat fields Ranunculus spp. recorded maximum IVI. Wheat fields (above 1600 MSL) showed maximum IVI of Capsella bursa-pastoris.
