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 .


Previous Next End

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.


Previous Next End

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

azospirillum 3-3.5g / 300-350 g of seeds.


Previous Next End

The treated seeds have to be sown

in lines drawn 10cm apart 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 pro trays.)

Prepare the nursery area of 3 cents

with a slanting slope of 2%.

Cover the nursery area with 50%

shade net cover the sides using

40/50 mesh insect proof nylon net.


Previous Next End

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 coco peat @ 300kg with 5 kg of neem cake

along with azospirillum and phosphobacteria each @ 1 kg.

approximately 1.25 kg of coco peat mixture is required for

filling one portrays.


Previous Next End

A total number of 238 pro trays 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 pro trays @ 1 seed per cell.


Previous Next End

Cover the seeds with coco peat 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 up to seed germination drench

19:19:19 NPK complex @ 0.5% (5g/lit) at 18 days after sowing.


Previous Next End

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 azospirillum 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.

Main field preparation:


Previous

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.
