Which of the following does not help in weed control in crop production? Correct Answer Transplantation

Concept-

  • In a field, many other undesirable plants may grow naturally along with the crop. These undesirable plants are called weeds.
  • Weeds appear suddenly in the field without any planting or sowing.
  • Weeds are harmful as these compete with the main crop for nutrients, water, light, and space, and badly affect the growth and production of the main crop.
  • Weeds may also act as alternate hosts for many stages of insect pests and pathogens.
  • They occupy land, spread fast, and hence, require regular eradication.

Explanation-

  • The removal of weeds is called weeding.
  • Weeding is necessary since weeds compete with the crop plants for water, nutrients, space, and light.
  • Various agronomic practices, such as crop rotation, intercropping, mechanical removal of weed, etc., have been found effective in weed management
  • Crop rotation
    • In monoculture farming, one type of weed grows with one particular type of crop.
    • Crop rotation helps to break the life cycle of weeds and prevent any weed species to dominate.
  • Intercropping
    • It suppresses the weeds better than the mono-cropping system.
    • It gives advantages to utilizing crops themselves as tools for weed management. 
  • Mechanical methods are of many types for example Mowing the weed, Mulching the field, Hoeing, etc.

Therefore the correct answer is Transplantation.

Additional InformationTransplantation

  • The technique of moving a plant from a place where it has been growing and replanting at another site during the growing season is called transplantation.
