Definition and Characteristics of Weeds

Damages caused by Weeds

INTRODUCTION

Weeds are the plants, which grow where they are not wanted. They grow in fields where they compete with crops for water, soil nutrients, light and space and thus reduce crop yields. They also harbour insects, pests and micro- organisms. Certain weeds release into the soil the inhibitors or poisonous substances which are harmful to the plants, human being and livestock. They increase the expenditure on labour and equipment, render harvesting difficult and reduce the quality and marketability of agricultural produce.
