Phyto-sociological Studies of Sugarcane Crop and its Weed Communities

Weed communities of sugarcane crop were determined by using quadrate method at three different sugarcane growing localities of District Meerut, during 2009-10. A total of 14 weed species distributed across 12 families were recorded. Among all weeds, Gnaphalium luteo-album had the highest average density (21.5/m²). Three species were dominant, i.e. Gnaphalium luteo-album (21.5/ m2), Antirrhinum majus (8.5/m²) and Trigonella foenum-graecum (2.2/m²). In the present study, these three species were concluded as the most competent weeds which enter into real competition with the sugarcane crop.
