Dapog method for paddy transplantation

Wet-bed paddy tranplantation    

  • Compute the seed & seedbed area: 50 kg seed & 500 m2 seedbed area for TP one ha of main field
  • Locate the seedbed away from electric light in a fertile field that is easy to irrigate & drain
  • Start preparing the seedbed 2 weeks before planting time.
  • Add organic manures and/or fertilizers as needed
  • Irrigate, plow, puddle and level the field
  • Prepare beds of 1 to 1.5 m width, 4-5 cm height & any convenient length
  • Pre-germinate the seeds 2 days before sowing: 24 h soaking & 24 h incubation
  • Sow the pre-germinated seeds on beds
  • Water the seedbed 2-3 DAS and then maintain a water level of 2-5 cm, depending on the height of seedlings
  • Apply 20-40 g urea or DAP per m2 at 10 DAS, if needed
  • Apply pesticide only when needed
  • Seedlings are ready for TP from 20-25 DAS 

Dry-bed paddy tranplantation 

  • Compute the seed & seedbed area: 50 kg seed & 500 m2 seedbed area for TP one ha of main field
  • Locate the seedbed away from electric light in a fertile field with light soil and easy access to a water source
  • Start preparing the seedbed 2 weeks before planting time
  • Add enough organic manures &/or fertilizers
  • Plow and harrow the field
  • Prepare raised seedbeds of 1.5 m width, 0.1-0.15 m height, and any convenient length
  • Seed priming: weigh required quantity of clean seed, soak for 24 h and then dry in the shade
  • Primed seed is reported to germinate faster than fresh dry seed
  • Sow the primed seeds on raised beds & cover the seed lightly with soil or rice hull
  • Water the seedbed till saturation after sowing
  • Then water the bed periodically as seedlings emerge & grow
  • Regulate the water supply, if necessary,  to control the rate of seedling growth
  • Apply pesticides to control pests, if needed
  • Seedling are ready from 25-30 DAS

Dapog (Mat) paddy tranplantation 

  • Less labor need
  • Shorter period of raising seedlings
  • Easy transport of seedling-mats to main field
  • Preferred for mechanical transplanting
  • Select a level area near the household and/or a water source
  • Mark out 1 m wide and 10 to 20 m long plots
  • Spread a plastic sheet or banana leaves on the marked area
  • Form the boundary with bamboo splits or banana sheath
  • Spread the pre-germinated seeds at the rate of 1 kg per 1.5 m2 area
  • 40-50 kg seed sown in 60-75 m2 area is enough to plant one ha of main field
  • Sprinkle water immediately after sowing and then as and when needed
  • Protect the mat nursery from heavy rains for the first 5 DAS
  • Seedlings will be ready for sowing in 8 to 15 DAS
  • Roll out the seedling mats and transport them to the mail field


Modified mat paddy tranplantation 

  • Reduced nursery area: 100 m2 to plant 1 ha
  • Establishing seedlings in a 4cm layer of soil mix, arranged on a firm surface
  • Robust, young seedlings (18-20 cm tall with 4 leaves) produced within 15 DAS
  • Easy transportation of seedling-mats to main field
  • Easy separation of seedlings for transplanting (minimum root damage
  • Prepare 100 m2 nursery area to plant 1 ha. Select a level area near the household and/or a water source
  • Mark out 1 m wide and 10 to 20 m long plots Spread a plastic sheet or banana leaves on the marked area
  • Place a wooden frame with 4cm deep and convenient size segments Fill the frame with soil mixture
  • Seed: To plant 1 ha, use quality seed @ 9-12 kg seed (for 20 x 20 cm spacing at 1 seedling per hill) 18-25 kg seed (for 20 x 20 cm spacing at 2 seedling per hill)
  • Sow pre-germinated seeds at the rate of 100 to 150 g per m2 area and cover the seed with dry soil and press it gently
  • Sprinkle water immediately to soak the bed
  • Then water the bed as and when needed to keep it moist all the time
  • Protect the nursery from heavy rains for the first 5 DAS
  • Continue watering until 15 DAS
  • If the nursery can be flooded, flood the nursery area with 1 cm water level all around at 6-7 DAS
  • Optional: Sprinkle 0.5% urea solution at 9 DAS, if seedling growth is slow or leaves are yellowing (1.5 kg urea/300 l for 100 m2 area)
  • Seedlings reach 18-20 cm tall at 15 DAS
  • If flooded, drain the water 2 days before lifting the seedling-mats
  • Lift & transport the seedling-mats to mail field
  • Separate the seedlings and transplant them at 1-2 per hill at 20x20 to 25x25 cm spacing

Modified Mat Nursery-2:

Preparing Soil Mix

soil                            : 70-80%,

Decomposed manure  : 15-20%,

Rice husk                   : 5-10%,

Powdered DAP            : 1.5 kg/100 m2
**4 m3 soil mix for 100 m2 nursery area
