Tillage is the physical manipulation of soil with tools and implements for obtaining conditions ideal for better seed germination, seedling establishment, and growth of plants is called tillage. Objectives of tillage are:

  • To facilitate adequate soil aeration for gaseous exchange in the seed and root zone
  • Adequate seed-soil contact to permit water flow to seed and seedling roots
  • A non-crusted soil to permit seedling emergence
  • A low-density soil that permits root elongation and proliferation
  • To create an environment that provides adequate light to the seedling (weed-free environment).
  • To create pest and pathogen-free environment
  • To mix the applied manures and fertilizers with the soil
  • To remove the hardpan, if any to increase the soil depth for water absorption
