Abstract

A study was conducted during summer season of 2001 to 2004 with an objective to document the important weeds of potato crop in Nilgiris based on their importance value index. The data were collected on species-wise weed count, fresh weight, frequency of occurrence and canopy coverage on 45th day of potato planting. The results indicated that Coronopus didymus and Polygonum nepalense were the two major weeds of potato crop in Nilgiris hills. Weed management strategy for these weeds has been suggested.
