Q
Crop Production and Management

Question:

What are weeds? How can we control them?

Answer:

The undesirable plants which grow along the cultivated crop are called weeds. The growth of weeds is harmful because they consume the nutrients present in the soil, water, light, and space which are meant for the crops and reduce the crop yield and quality of food grains. Therefore, it is necessary to remove the weeds from time to time. The removal of weeds is called weeding. 

Methods to remove weed:

1. Chemicals used to control weeds are called weedicides. Ex: 2, 4-D is weedicides. These are sprayed in the fields to kill weeds; they do not harm the crops. 

2. Weeds can be removed manually, by uprooting or cutting them close to the ground with the help of khurpi.
