Introduction
• Well drained upland field with sandy loam soil near irrigation
source is selected for bed preparation.
• 500m2 nursery produces seedling sufficient for 1 ha field. Beds 1-
1.5 m wide and length depending upon the slope and structure of
soil are made. Raised beds are ideal if the soil is clayey.
• Wet bed, dry bed and SRI Nursery are the three major methods
of raising rice seedlings in a nursery.

Nursery Site Selection:
Nursery should be located away from electric light as they attract
insects at night.
Location: Near irrigation source, leveled, and convenient for
cultural operations and free from stubbles, stones, etc.
Soil Characters: Fertile, rich in organic matter, free from soil
borne pathogens, nematodes, pests and weed seeds.

Land Preparation
Dry Nursery: Summer ploughing reduces the water requirement for
initial land preparation. Flood the field 1 or 2 days before ploughing
Wet Nursery: Add organic manures as needed. Irrigate, plow,
puddle and level the field
SRI Nursery: Seedlings raised in egg boxes filled with medium is
advantageous but conventional wet beds can be used. The addition
of organic manure is advisable.

Seed Bed Preparation for Dry nursery
• Raised beds of 120 cm wide, 15 cm high and any convenient
length should be prepared with a channel half a meter wide all
round them to facilitate drainage.
• 30kg FYM must be added in 15 m2 nursery bed.

Seed Bed Preparation for Wet Nursery
Leveling of seed bed surface
• Seedbeds are 2.5m wide and 8-10m
long depending on soil and slope.
• 30cm wide drainage channels are dug
around seedbeds.
• Collect the puddled soil from channel
and spread it on the seedbeds so as
to raise them.
• Level surface of seedbeds so that
water drains into the channels.

Seed Bed Preparation for SRI Nursery
• Raising seedlings in egg boxes filled with vermicompost or
organic manure is also advantageous.
• Conventional wet beds are commonly used for raising seedlings
by SRI method.
• Addition of organic manure before sowing is advisable.
