  • Spread a plastic sheet or used polythene gunny bags on the shallow raised bed to prevent roots growing deep into soil.
   
Preparation of soil Mixture :
  • 4 m 3 of soil mix is needed for each 100 m 2 (2.50 cents) of nursery. 

  • Mix 70% soil + 20% well-decomposed pressmud / bio-gas slurry / FYM + 10% rice hull. Add the soil mixture 1.5 kg of powdered DAP or 2 kg 17-17-17 complex fertilizer.

Preparation of soil Mixture

Blending Soil Mixture

Filling in soil mixture : Place a wooden frame of 0.5 m long, 1 m wide and 4 cm deep divided into 4 equal segments on the plastic sheet.

Fill the frame almost to the top with the soil mixture. : Soak the seeds for 24 h, drain and incubate the soaked seeds for 24 h, sow when the seeds sprout and radical  (seed root) grows to 2-3 mm long.

Pre-germinating the seeds 2 days before sowing : Soak the seeds for 24 h, drain and incubate the soaked seeds for 24 h, sow when the seeds sprout and radical  (seed root) grows to 2-3 mm long.

Soil application  of   biofertilizers : Application   of Azospirillum  @ 2 kg and   mycorrhizal fungi @ 5 kg for 100 m2 nursery area


Blending Soil Mixture

Sowing :

  • Sow the pre-germinated seeds weighing 90 -100 g/m 2 uniformly.
  • Cover them with dry soil to a thickness of 5 mm.
  • Sprinkle water immediately using rose can to soak the bed.


    

Sowing Sprouted Seeds

Watering:
