Raising seedling for transplanting for
one hectare an area of 350 meter
square nursery required generally
raised nursery beds of size 7.5m ×
1.2m × 0.1m are prepared.
The beds are covered with a layer of
farm yard manure and sand mixed in
equal proposition during rainy season
there will be heavy incidence of
damping off .

So the nursery bed should be
drenched with 0.2% diathane M -45
about 300-350g of seeds would
required in the case of varieties.
While for hybrids a quantity of 150g
will be sufficient to transplant one
hectare.

Treat the seeds with Trichoderma viride or Psedumonas fluorescens
10g or carbendazim 2g per kg of seeds 24 hrs before sowing.
Just before sowing the seeds have to be treated with azospirilliun 3-
3.5g / 300-350 g of seeds.

The treated sees have to be sown in
lines drawn 10cm aprt in the raised
beds and covered with sand.
A thin layer of paddy straw can be
spread on these beds and the beds
are watered every day by rose can.

Protected nursery for hybrids:
(seedlings raised in protrays.)
Prepare the nursery area of 3 cents with
a slanting slope of 2%.
Cover the nursery area with 50%
shadenet cover the sides using 40/50
mesh insect proof nylon net.

From raised beds of 1m width and convenient length. Place HDPV
pipes once in 2m interval for further protection with polythene sheets
during rainy months.
Mix sterilized cocopeat @ 300kg with 5 kg of neem cake along with
azospirilliyum nad phospobacteria each @ 1 kg. approximately 1.25
kg of cocopeat mixture is required for filling one portrays.

A total number of 238 protays are required for producing 23, 334
seedlings which is required for transplanting one hectare at a
spacing of 90cm 60 cm × 60 cm in paired row system.
Sow the treated seeds on protarys @ 1 seed per cell.

Cover the seeds with cocopeat and keep the trays one above the
other and cover with a polythene sheet till germination starts.
After 6 days, place the germinated portrays individually on the
raised bed inside the shade net.
Water with rose can every day upto seed germination drench
19:19:19 NPK complex @ 0.5% (5g/lit) at 18 days after sowing.

Plough the land to a fine tilth thoroughly prepare the field with the addition of FYM @ 25t/ha.Form ridges and furrows at a spacing of 60cm . apply 2kg of azospirillium and 2kg of phosphobacteria by mixing with 50 kg of FYM for one hectare.Irrigate the furrows and transplant 25 days old seedlings with the ball of earth on the ridges. Life irrigation to be given on 3rd days.

Mulching and weed control:
Black LDPE sheets 25 microns
thickness may be buried at both the
ends into the soil to a depth of 10cm
before mulching apply pendimethalin
1.0kg a.i/ha.
As a pre emergent herbicide just
before transplanting.
