Weeds are the unwanted plants that grow along with crops affecting the growth of crops hence they need to be removed.
Removal of weeds can be done by several methods: i) Tilling during the preparation of soil helps in uprooting and killing weeds. ii) Manual removal of weeds by uprooting them close to the ground, from time to time with the help of khurpi. iii) Weeds can also be removed with the help of certain chemicals called weedicides e.g., 2,4-D.
