MP Board · Class 9 · Science · Improvement in Food ResourcesWhat are Weeds? Give two examples and mention why their removal is necessary from crop fields.
Step-by-Step Solution
Weeds are unwanted, wild plants that grow naturally alongside cultivated crops in an agricultural field. Common examples include Xanthium (Gokhroo) and Parthenium (Gazer ghas). Their removal is necessary because weeds compete aggressively with main crop plants for space, sunlight, water, and essential soil nutrients, thereby drastically reducing crop quality and overall agricultural yield.
