About Crop Manager for Rice-based Systems

Crop Manager for Rice-based Systems (CMRS) aims to increase farmer's net income and sustain the productivity for rice-based cropping systems in Bihar, India. CMRS provides irrigated and rainfed farmers with rice-based cropping systems in Bihar with a crop and nutrient management guideline customized to the needs of an individual farmer. CMRS uses a farmer's answers to questions on farming practices to automatically generate a rice, wheat, or rabi maize management guideline aimed at increasing the farmer's net income.

CMRS 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 can be 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 CMRS 'model', which calculates and transmits a crop management guideline for rice, wheat or rabi maize in rice-based croppping systems 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 the farmer. The guideline is then provided to the farmer as a one-page printout, which the extension worker, input provider, or provider of services can also use to advise the farmer on how to increase net income through improved crop management.

The concept and framework for CMRS was developed by IRRI. The nutrient management guideline provided by CMRS 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 and the more recent Nutrient Manager for Cereal Systems developed by IRRI provide the SSNM-based, nutrient management component in CMRS.

The Rice Crop Manager developed by IRRI in 2013 for the Philippines provided the framework for the crop management decision-making logic used in the subsequent Crop Manager for Stress-Tolerant Rice (CMSTR), Rice-Wheat Crop Manager (RWCM), and Rice-Maize Crop Manager (RMCM), which are now combined in CMRS.

CMSTR was adapted, evaluated, and verified for rice cultivation in Bihar through collaboration of IRRI with Bihar Agricultural University (BAU), Catholic Relief Services (CRS), the Indian Council for Agricultural Research (ICAR), and Rajendra Agricultural University (RAU). The development of CMSTR was made possible through support from the Improved Rice-based Rainfed Agricultural Systems - Bihar, India (IRRAS), funded by the Bill and Melinda Gates Foundation and implemented by Catholic Relief Services (CRS).

RWCM was adapted, evaluated, and verified for rice and wheat cultivation in Bihar through collaboration of IRRI with BAU, the International Maize and Wheat Improvement Center (CIMMYT), ICAR, and RAU. RMCM was adapted for rice and maize cultivation in Bihar through collaboration of IRRI with CIMMYT.

The development of RWCM and RMCM was made possible through support from the Cereal Systems Initiative for South Asia (CSISA), funded by the Bill and Melinda Gates Foundation and the U.S. Agency for International Development and the Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI) project, funded by the Australian Centre for International Agricultural Research (ACIAR).

Terms and conditions

Crop Manager for Rice-based Systems provides a crop and nutrient management guideline for rice, wheat, and rabi maize grown in irrigated and rainfed environments. The use of this software is subject to the following terms and conditions:

The International Rice Research Institute (IRRI) does not endorse or promote specific agricultural inputs and fertilizers, and it does 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 Crop Manager for Rice-based Systems - such as climate and water availability - affect rice, wheat, and maize yield. IRRI does not guarantee a targeted rice, wheat, and maize 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 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.
