What is happening?

We all know

Rice price has gone up, and may not come down significantly soon

Poor farmers are suffering the most

Due to the floods and sidr, there is a shortage of about 2 million tons


World rice prices are jumping up like mad horse


Why it is happening:

Our domestic production is low and we are consuming more

World stock and supplies of rice are also in precarious condition, and may not ease in the next few years

Range of multiple factors are contributing

to uncertainty in availability of enough

rice at reasonable price from global market


Rising oil price is also contributing to increasing input prices

Cost of production is going to be higher, and

days for cheaper rice

is not expected

soon


The current sharp increase in rice price is a major cause for concern.

Even a small increase in price can seriously affect the household food security of poor people. For example, a 25% increase in rice price translates into a 7–10% drop in the real income of poor consumers, as rice purchases often constitute 30–40% of their total expenditures.

This makes vulnerable more vulnerable


What could be done

Ensuring sufficient supplies of rice that is affordable for the poor is thus crucial to poverty reduction.

The best strategy for keeping the price of rice low is to ensure that production increases faster than demand.

Although some increase in cropping intensity and growing rice on current fallows are still possible, rice land otherwise is being lost to industrialization, urbanization, or conversion to other crops.


The main source of additional production will, therefore, have to be yield growth.

Productivity growth through the development and dissemination of improved technologies is the only long-term viable solution for bringing prices down, preventing future increases in price, and ensuring that affordable rice is available to poor rice consumers.

Needs An Agronomic Revolution: Reducing yield gap through improved skills in management of resources and technologies farmers use

Expand rapidly, use of recently developed technologies and HYVs

Develop technologies to enhance productivity, particularly of the unfavourable – floodprone, droughtprone and salinity prone – ricelands

Policies to improve input and output marketing system


IRRI, in partnership with BRRI, can offer a range of technologies to increase domestic production at a faster speed and enhance farmers’ income.

Successful adoption of these options can easily eliminate the shortfall, rather can have surplus production

And, are capable of developing technology choices for the future

Investments are needed

to make these technologies available to rice farmers in the short to medium term, and

to develop new technologies in the medium to long term


Promising options and technologies

• Enhancing skills and capabilities of farmers in using recommended technologies to harvest the potential yield

• Speed-up adoption of recently developed technologies suitable for various agro-ecosystems

o HYVs – BRRI Dhan 44, 47, 33, BR11 sub1 and Swarna sub1

o Improved seed and seedling management

o Direct wet and dry seeding using drum seeder and lithao

o Use of leaf color chart (LCC) for real time N management

o Growing of rice and other food crops in the tidal saline areas with sweet water harvesting

o Alternate wetting and drying (AWD)

o Integrated crop and resource management

o Reduce post harvest losses


Validate to Scale up adoption of varieties

BRRI Dhan 44 has potential to be a mega variety

BRRIdha47 for saline areas

BRRI Dhan 33 for monga areas and in areas where short durated rice varieties are needed

BR11 sub1 and Swarna sub1 can withstand submergence for up to 14 days

New variety coming up with salt tolerant (Saltol) gene


Improved seed production and preservation at farm level, and seedling raising

• Can increase the yield by about 5 -10%


Direct seeding by Drum Seeder

• Direct wet seeding of sprouted seeds in paddled lands by using Drum Seeder increases yield by about 10- 15%, saves costs and ensures early harvest.


Leaf Colour Chart (LCC) for N Management

• LCC is usually a plastic ruler-shaped strip containing four panels , clors matching the paddy

• Reduces N use by up to 30% and enusres discipline in N application

• LCC helps improve yield by maximizing crop N uptake and reducing N losses.


Technology are seen in the field

Alternate Wetting and Drying (AWD)

AWD is a technology for water saving for rice production. A simple device has been designed to observe water level in the ground to decide time & amount of irrigation water.

Saves water by about 30-45% and has tendency to increase yield


Integrated Rice-Fish Culture

Integrated Rice-Fish culture is a high potential farming in Bangladesh during monsoon (on flood-free land) and boro seasons. However, this practice is yet to gain wide popularity, as it deserves.


Rice-fish culture offers the following benefits:

• Increase income from increased production of both rice by about 10% and additional production of fish;

• Recycles nutrients by fish through feeding and depositing fish faces in the soil;

• Provides protein to members of farmer’s family;• Reduces insect pest (leaf hopper, stem borer, aphid

etc.) and weed infestation as they are consumed by fish and

• Reduces the amount of chemical fartilizers needed for rice cultivation


Growing of rice and other food crops in the tidal saline areas with sweet water harvesting

• Boro rice or other crops can be irrigated by utilizing gravity flow of tidal water directly from the river during high tide from mid-November to mid-February.

Before it becomes saline, river water can be conserved in natural canals at the beginning of February to irrigate rice or other crops from mid-February to end of March with a low lift pump.


Integrated Rice-Duck farming system• The system of rice cultivation along with duck is know

as Intenerated Rice-duck Farming System. It is a form of organic farming that facilitates the poor farmers/households to obtain two crops (rice as the main crop and ducks is the subsidiary crop) simultaneously utilizing same natural resources.

In rice-duck system agro-chemicals and chemical fertilizers are not applied. So this system is cost-effective and environment friendly.
