Question

10. (i) What are weeds?
(ii) How can we control them?
(iii) Why should weeds be removed?​

Answer 1

Answer:

Weeds are unwanted and uncultivated plants that grow with crops and compete with crops for nutrients and can also cause crop toxification. Weeding is removal of weeds and is mostly done before flowering begins in crop plants. It is done using trowel, harrow or weedicides. Trowel is used in manual removal of weeds. They should be removed because they absorb the nutrients from the soil which may make the crop plants unhealthy.
