Explanation: 4 Marks
In the field, many undesirable plants may grow naturally along with the cultivated crop. These undesirable plants are called weeds. The removal of weeds is called weeding.
Weeding is necessary as they compete with the crop plants for water, nutrients, space and light. In this way, they affect the growth of the crop. Some weeds interfere even in harvesting and may be poisonous for animals and human beings. Weeds by the name of Onion Grass, Paddy's Lucerne, parrot's feather, Paterson's curse are commonly seen growing along with crops.
