About 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 (DA-BAR).

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 any character including, without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses, specifically including damages to crops and soil resulting from the application of the software, or for any damages or liabilities even if IRRI shall have been informed of the possibility of such damages or 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.
