Selecting Pricking Out and Transplanting of Germinated Seeds to Polythene Pots

Selecting Pricking Out and Transplanting of Germinated Seeds to Polythene Pots

To attain uniform growth and high survival rate in the field, select and uproot the germinated seeds carefully by hand using a dibble or hand trowel.

Materials needed

  • Sprinkler
  • Container with water
  • Clean water
  • Potted polytubes
  • Watering can

Activities

  • Water the germination bed first.
  • Uproot the seedlings with two leaves one by one.
  • Place the uprooted seedlings in a container half-filled with water to maintain turgidity and to avoid damage before transplanting to the poly pots.
  • Discard retarded, deformed or diseased seedlings because they have less chances of survival.
  • Bring to the area to be planted in polythene bags.

Watering

  • Keep the seedbeds moist, not wet.
  • Do not water at a fixed time each day. Water when the plants need it.
  • Small seedlings require less amount of water. Large seedlings require more water more often.
  • Seedlings require more water more often on windy and sunny days. Water less often when seedlings are kept in a shade.
  • Moss and algae growth is an indication of excess watering. Always use clean water; dirty water may cause diseases.
  • Over-watering results in weak plants and causes diseases such as root-rot and damping off of seedlings.

Transplanting

  • Water mother beds thoroughly before transplanting the seedlings.
  • Always use some tools (e.g. bamboo sticks) to loosen the soil before pulling out seedlings from the beds.
  • Make a deep and wide hole in the polythene bag or container for transplanting the seedlings. Hold seedlings at the base of the stem and pull it out gently from the mother beds.
  • Never bend the roots and do not force the seedlings into the hole. Keep transplanted seedlings under proper shade until they have recovered.

Hardening of seedlings

In a nursery, seedlings are kept under ideal conditions; therefore hardening is essential to make them strong enough to tolerate the harsh conditions of the planting site. It is generally done by reducing the amount of watering about one month before the date of planting.
