Characteristics of good quality seed
● no contamination or admixture in the seed
● high germination capacity
● free from disease
● high germination capacity
● free from weeds, soil particles, sand and stones
● no broken seeds
● true-to-type genetic purity

Cultivation Guide for Hybrid Rice
Varieties:
● Bangladesh Rice Research Institute developed 4 hybrid
rice varieties namely, BRRI hybriddhan,1, 2, 3, for Boro
and BRRI hybriddhan4 for T.aman.
● hybrid rice variety seeds are available both imported and
local production.
● To collect seeds a farmer have to consider reliability of
the company and the desired grain quality which are seen
from outside of the packet.

Soil Testing:
Have your land tested by the Soil
Resources Development Institute or
Department of Agriculture Extension as
liaison office to know its fertilization and
acidity level. In this way, you will be
informed about the right amount of
fertilizer to be used and if your soil still
needs lime.

Land Preparation
Prepare the land two to three weeks before
transplanting to ensure the fast and ideal
growth of the Pioneer Hybrid Rice to be
planted. This will hinder the early growth of
weeds and help in proper management of
fertilizer and farm irrigation.

Plowing. Plow the land once with a medium
depth, preferably 10-15 centimeters. However,
it may not be necessary if there is enough soft
soil for transplantation of seedlings.
Leveling: Level the land with the use of a
plowshare or a hand tractor.
Dike reconstruction: Clean and fix the
embankments to close up any holes that may
serve as rats' nest or waterway that will lead
to water spillage.

Seed and Seedbed Preparation
Choosing the seedbed: Choose an area of the
farmland which is far from the shade.
Preparing the seedbed: Make a 300-400 sqm
seedbed for a 15-20 kg of seeds, good for one
hectare of land. A seedbed is considered
medium if it is one meter wide; its length
depends on the cut of the paddy. Put organic
fertilizer with the quantity of 1 kg per sqm to
making the seed grow healthy and pulling out
easier to lessen damage to the roots.

Soak the seeds in clean
water for 24 hours.
Regularly change the water
every 6 hours in order to
prevent the seeds from
spoiling. Cover it and keep
it airtight for 24-36 hours.
Make sure that you keep the
seeds damp.
Preparing the seed for seedbed
Germinated seeds

Irrigate the seedbed after 2-3
days with a depth of 2-3 cm.
Keep the seedbed well irrigated
until the day when you will pull
the seedlings out. On the tenth
day, strew 20-40g of urea per 1
sqm or 8-16 kg per 400 sqm. It is
important that the seedbed be
guarded from damage brought
upon by birds and lack of
irrigation.
Seeding on bed: Grasp a handful (50 grams per 1 sqm)
of the seedlings and spread them to the damp seedbed.
Nursing the seedlings

A seedling that is 18-21 days old
can already be transplanted.
Sow 1-2 seedlings per hill with a
distance of 20 x 15 cm during
dry season and 20 x 20 cm
during wet season. Do not trim
the leaves of the rice because the
wound may let in bacteria that
will cause plant diseases. Sow
seeds to the missing hills within
a week.

Fertilizer Application

If a soil analysis was not conducted on your land,
please refer to the following recommendations:
Basal: Strew basal fertilizer on the last harrowing
session so that it will be mixed well with the soil.
Top-dress: Spread the fertilizer during the tillering,
vegetative and reproductive stages.
For the right kind and amount of fertilizer to be used,
please refer to the table below:

Basal (1 day before transplanting) TSP 500 /grams/decimal
MOP 300 /grams/decimal
Zinc Sulphate 40/grams/decimal
Gypsum 250/grams/decimal
Early Tillering (7-10 after transplanting) Urea 300/grams/decimal
Late Tillering (21-25after transplanting) Urea 500-600/grams/decimal
Panicle Initiation (7 days before) Urea+ As on crop condition
Panicle Initiation (7 days before) MOP 150/grams/decimal
Recommendation depends on soil fertility and yield potential of the variety the thumb
rule for production of rice 6ton/ha apply 108kg N, 18kg P, 120kg K and 11S/ha.

Irrigation and water Management
During the early vegetation stage, it is fit that the water
depth is at 2-3 cm. At maximum tillering stage when
the desired no of tillers are produced dry the land up to
small creaks appeared. This will help in the growth of
roots and prevent unwanted tillering. Raise the water
level to 5-7 cm during the reproductive stage and keep
it at that level until the grains are milky. The rice paddy
may be drained 1-2 weeks before harvest.
* Do not select a plot where water stands all time and
out of control of irrigation water particularly near the
irrigation pump or plots at lower areas. Due to higher
seed cost 1-2 seedlings are used/hill so for better
tillering water level in the fields need to be very low at
that stage.

Controlling the weeds:
Proper management of the irrigation is the
most effective way of controlling weeds.
Exterminate the weeds in the rice paddy on
the first 40 days after transplanting. Use
bare hands, rotary weeder or any
recommended herbicide in controlling the
weeds.

Managing the pests
Time your planting with the other farmers in your
community. In this way, you will be able to prevent
insects and plant diseases from attacking your
farm. It is also advised that rice farmers practice the
principles of the Integrated Pest Management. This
includes combinations of various ways to eliminate
or control pests without damaging the possible
yield and earnings of the farmer.
Pest that attack leaves: Since rice have the
ability to replace damaged leaves within the first 40
days after transplanting, it is expected that
pesticides will not be needed anymore.

Stem borer: Use a systemic pesticide on the base of the
rice plant when there are a lot of white heads and dead
heart in the plant. Moths or egg cluster 2-3/meter
square up to 40 days after planting or 10% dead
heart/square meter upto 40days after transplanting or
5% dead heart upto 60 days after transplanting.
Rats: Use rat poison if there are already too many of
them in your farm. Keep the rat traps up to two weeks
before harvest time. Keep the embankments clean so
that rats will not inhabit them.
Managing the pests cont.

Disease:
In pest management, avoid
excessive usage of nitrogen, a high
population of weeds,
asynchronous planting and
continuous irrigation. You may use
recommended pesticides in
eliminating diseases in your rice
fields.
For Blast apply Hinosun
800ML/ha and for Sheath blight
spray 500ML/ha Folikul

Sheath Blight
Blast

Harvesting:
Start harvesting the rice
when 80-85% of the
grains are already ripe.
Thresh the harvested
rice grains right away.
Introduction of combine
harvester started in
Bangladesh due to
scarcity of farm labor.
