What is Rice Crop Manager?
• A decision-making tool
accessible on computers
and smartphones
• Can be used by extension
workers to interview a
farmer and provide advice
to a farmer
• Aims to provide
management advice able
to increase a farmer’s
income by Taka 8000 per
hectare per rice crop
Why we need Rice Crop Manager
Rice in Bangladesh is typically produced in
small landholdings
• Farming practices vary
among farmers and fields
• ‘Best bet’ management
practices can vary among
nearby fields
Rice farmers often do not
properly apply fertilizer
• Wrong times
• Wrong amounts
• Wrong sources
Field-specific nutrient management
practices are needed for rice farmers
Factors affecting crop
needs for nutrients vary
among fields:
• Yield of the crop
• Management of crop residue
• Nutrients in irrigation water
• Past crop
• Past fertilizer use
• Nutrients in soil
Farmers need an actionable management guideline
matching their field and rice-growing conditions
The challenge: The best practices for growing
rice differ among fields and farmers
Fields vary in rice-growing Farmers vary in access to
conditions
financial resources, inputs, and
technologies
Farmers need information to increase income
for their specific rice-farming situation
RCM can provide
a farmer with
‘field-specific rice
production
guidelines’ as
recommended by
BRRI
Our approach: Use Information and
Communications Technology (ICT) to
deploy information to farmers on optimal
rice farming practices
• Effectively use results from research
• Increase income of farmer
• Use computers, Tabs, and smartphones

IRRI with NARES partners developed
Nutrient Manager for Rice to provide
farmers with ‘precise’ fertilizer management
• Used scientific principles
from years of research
• Aimed to increase income
of farmer by US$100 per
hectare per crop
• Provided customized
recommendation for a
farmer’s field through
mobile phone or computer
Collaboration with BRRI started from
2000

2005: Collaboration led to site-specific nutrient
management (SSNM) for ‘precise’ management of N, P,
and K
BRRI and IRRI developed Nutrient
Manager for Rice (NM Rice)
• Used recent advances
in ICT
• Incorporated recent
developments in
science
• Recommended by
BRRI in October 2012
Users requested a tool providing more than
nutrient management. Nutrient Manager for
Rice was upgraded to Rice Crop Manager
Rice Crop Manager was tested, recommended and
released nationwide in the Philippines and
Bangladesh in November 2013

Approaches tested for RCM dissemination

Approach 1:
DAE – UIC: DAE staff interviewed farmers with NM questionnaire and submitted
the completed questionnaire to a UIC operator. The UIC operator entered
information on the questionnaire into NM and developed NM
recommendations, which were distributed by DAE staff to the farmers.

Approach 2:
DAE – PE: Same as approach 1 but PE – computer operator instead of UIC
operator made the NM recommendations.

Approach 3:
Farmer – UIC: Farmers encouraged went directly to UIC operator. UIC operator
interviewed them, made NM recommendation, and provided a printout.

Approach 4:
Farmer – PE: Same as approach 3 but PE – computer operator instead of UIC
operator interviewed farmers and made NM recommendations.
 Approach 1:
BRRI – DAE: BRRI scientists with their own laptop and printer interviewed
farmers, made the NM recommendations, printed and provided to the
farmers.
In all cases DAE, UISC personnel were provided with training on
RCM by BRRI and IRRI scientists
