Rice Crop Manager
Rice Crop Manager provides irrigated and rainfed lowland rice farmers in the Philippines with a crop and
nutrient management guideline customized to the needs of an individual farmer. Rice Crop Manager uses a
farmer's answers to questions on their rice farming practices to automatically generate a rice management
guideline aimed at increasing the farmer's net income.
Rice Crop Manager is designed for use by extension workers, crop advisers, input providers, and
providers of services who interview a farmer using a personal computer, smartphone, or tablet. After the
interview, the collected information is stored on the computer, smartphone, or tablet until the device is
connected to the Internet through a Web browser. Collected information is then transmitted via the Internet to
the Rice Crop Manager 'model', which calculates and transmits a crop management guideline within
moments back to the computer, smartphone, or tablet. Each guideline provides an actionable and unique
recommendation for the crop, which matches the location-specific cropping practices and needs of a farmer. The
guideline is provided to the farmer as a one-page printout and in some cases by SMS to the phone of the farmer.
The concept and framework for
Rice Crop Manager was developed by IRRI. The nutrient management
guideline provided by Rice Crop Manager is based on the principles of site-specific nutrient management
(SSNM), as developed for rice through partnerships of IRRI with national agricultural research organizations in
Asia. The Nutrient Manager for Rice developed by IRRI in 2008-2010 provides the SSNM-based, nutrient
management component in Rice Crop Manager.
The following organizations contributed to the formulation and field evaluation of
Nutrient Manager for
Rice, which is the precursor to Rice Crop Manager.
Rice Crop Manager developed by IRRI in 2013 for the Philippines includes crop management decision-making
logic, which draws upon long-standing research collaboration between IRRI and PhilRice and the expertise of each organization on rice cultivation.
Field evaluation of
Rice Crop Manager and the refinement of Rice Crop Manager to match local
needs and conditions for rice cultivation in the Philippines are made possible through a research partnership
of PhilRice and IRRI supported by the DA National Rice Program through the DA Bureau of Agricultural Research
The maintenance and deployment of
Rice Crop Manager are supported by the DA National Rice Program
through DA Agricultural Training Institute (DA-ATI).

Terms and conditions
Rice Crop Manager Philippines provides a crop and nutrient management
guideline for rice in irrigated and rainfed lowland environments of the Philippines.
The use of this software is subject to the following terms and conditions:
The Philippines Department of Agriculture (DA) and the International Rice Research
Institute (IRRI) do not endorse or promote specific agricultural inputs and fertilizers,
and they do not guarantee the accuracy of an analysis labeled on commercial agricultural
input and fertilizers. The software assumes that the N, P2O5, and K2O analysis labeled on
a bag of fertilizer or organic material accurately reflects the content of plant nutrients.
Many factors beyond the scope of Rice Crop Manager—such as climate and water
availability —affect rice yield. DA and IRRI does not guarantee a targeted rice yield will
be attained with the provided crop management guidelines.
The content of the software is subject to change without notice.
Limitation of liability
Under no circumstances and under no legal theory, whether tort, contract, or otherwise,
shall the DA and the Board of Directors of the International Rice Research Institute (IRRI)
or any of its affiliates, officers, employees, or other representatives be liable to you or
any other person for any direct, indirect, special, incidental, or consequential damages of

liabilities, or for any claim by any other party. This limitation of liability shall apply to
liability for death or personal injury except to the extent applicable law prohibits such limitation.
