About Rice-Wheat Crop Manager for Eastern Uttar Pradesh, India

Rice-Wheat Crop Manager aims to sustain the productivity of rice-wheat cropping systems and increase the net income of rice and wheat farmers in eastern Uttar Pradesh, India. It achieves this by providing farmers with a crop and nutrient management guideline customized to the needs of an individual farmer. Rice-Wheat Crop Manager uses farmer's answers to questions on his or her rice and wheat farming practices to automatically generate a rice or wheat crop management guideline aimed at increasing the farmer's net income.

Rice-Wheat Crop Manager is designed for use by extension workers, crop advisors, input providers, and agricultural service providers who interview farmers 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 Rice-Wheat Crop Manager 'model', which calculates and transmits a crop management guideline for the rice-wheat cropping system within moments back to the computer, smartphone, or tablet. Each guideline provides an actionable and unique recommendation, 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 service provider can also use to advise the farmer on how to increase net income from rice and wheat production.

The concept and framework for Rice-Wheat Crop Manager was developed by IRRI. The nutrient management guideline provided by Rice-Wheat 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-Wheat Crop Manager. The Rice Crop Manager developed by IRRI in 2013 provides the framework for the crop management decision-making logic used in the Rice-Wheat Crop Manager.

Rice-Wheat Crop Manager was adapted, evaluated, and verified for rice and wheat cultivation in Eastern Uttar Pradesh through collaboration of IRRI with Banaras Hindu University (BHU), the Indian Council for Agricultural Research (ICAR), and the International Maize and Wheat Improvement Center (CIMMYT).

The development of Rice-Wheat Crop Manager 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
Sustainable and Resilient Farming Systems Intensification in the Eastern Gangetic Plains (SRFSI) project, funded by the Australian Centre for International Agricultural Research (ACIAR)

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-Wheat Crop Manager - such as climate and water availability - affect rice and wheat yield. IRRI does not guarantee a targeted rice and wheat yields will be attained with the provided crop management guidelines. The content of the software is subject to change without notice.
