After harvesting
T. aman recommended basal fertilizers
are to be applied in the field
having optimum soil moisture.
After that wheat can be seeded
with the PTOS performing three
functions i.e. plowing, seeding
in 6 rows and laddering simultaneously.
There is no need to cultivate
the land separately. Before
seeding seed rate should be
adjusted by adjusting the metering
device.

Tiller Operated Bed Planter |

 |
| Power tiller
operated bed planter and
the bed planted crop |
|
| |
| Bed planting system brings a
new dimension in agriculture.
Power tiller opterated bed planter
has been developed by Wheat Research
Center. This equipment is suitable
for making bed and wheat seeding
on bed simultaneously. Other crops
like rice, maize, Mungbean, etc
can also be sown by this equipment.

Nutrient Management in Wheat-Rice
Cropping pattern |

Poultry manure
increases and sustains nutrient
availability especially, phosphorus
in soil, improves soil health
and increase system (rice-wheat)
productivity. Poultry manure
has direct and residual effect
in both wheat and rice yield.
Application of
3 tons/ha poultry manure (decomposed)
once a year with recommended
fertilizers (20% urea and TSP
can be reduced) increase system
productivity and sustain soil
fertility in wheat-rice pattern.
It would be wise to apply poultry
manure in dry land wheat crop
to get more residual effect
to next crop rice.

| Use
of Boron to combat sterility
|
| |
|
Sterility in wheat is usually
observed in light soil of northern
districts of Bangladesh causing
huge yield loss. To combat wheat
sterility, application of 1
kg/ha boron (Borax 9 kg or Boric
acid 6 kg/ha) and cowdung/compost
(7-10 t/ha) is suggested to
use along with the recommended
fertilizers. Application of
this technology in the field
will certainly increase grain
yield significantly by reducing
spike sterility. Boron should
be applied along with the basal
doses of fertilizers.

| Amendment
of acidic soil with Dolomite |
| |
|
Soil acidity has
become a problem for crop productivity
in Bangladesh specially, in
the north-western region. In
soil having low pH (4.0 to 6.0),
major nutrient elements and
molybdenum become unavailable
for the plants (P is the most
sensitive). Dolomite, a liming
agent, increases soil pH, the
availability of the nutrient
elements specially P, supplies
Ca and Mg in the soil and thereby
increases crop productivity.
Application of
Dolomite depends upon the range
of soil pH on soil. It is recommended
to apply dolomite @ 2.0 ton/ha
when soil pH ranges from 4.0-5.0,
and @ 1.0 ton/ha when soil pH
ranges from 5.0 – 6.0.
It remains effective in the
soil for about 3 years in rice-wheat
system.
There is no risk
involvement in adopting the
technology. However, application
of lime should be done 3 weeks
before sowing or transplanting.
However, higher dose of Dolomite
(in soil having pH higher than
6) may hinder uptake of K and
reduce micronutrient availability.

Seed
treatment with Vitavax-200 to
control seed borne diseases
|
|
|
Dry treatment
of seed with Vitavax-200 @
3 g/kg of seed before sowing
increases plant establishment
by 20% over untreated seed.
Yield advantage over untreated
seed is 10-12% at farm level.
Treated seed is prohibited
for consumption. Overdose
may reduce seed germination.
No adverse residual effect
is reported.
