Answer 2

Undesirable plants that grow along with crop plants are known asweeds. Xanthium, Parthenium, etc. are some commonweeds. Weeds compete with the crop for nutrients, light, and space.As a result, crop plants get lesser nutrients, light, and space fortheir development. This in turn, reduces their productivity. Thus,various weeding methods are employed.

Some important weeding methods are:

• Weeds can be controlled using weedicides. It is a chemical, which is sprayed in the fields to kill all available weeds. Weedicides are not harmful to crops.

• Tilling before sowing of crops also helps in removing weeds. Tilling uproots the weeds. The best time for the removal of weeds is before they produce flowers and seeds.

• The manual method of removing weeds is with the help of a khurpi. It involves regular uprooting or cutting of weeds close to the ground.
