Abstract:

Present study was conducted in the fields of Khairpur district, Sindh for the mapping of some important weeds of wheat and cotton by using GPS and GIS technology. A base map of the district was prepared by using Geographical Information System (GIS) to indicate the sampling sites and physical features of the area. Two more maps were created to depict the density and frequency of weeds of wheat and cotton crops in each Tehsil (Taluka), shown in the form of bar and pie diagrams. Present piece of work will help the scientists and managers to predict those areas, potentially subjected to weed invasion.
