About Maize Crop Manager for Bangladesh

Maize Crop Manager provides irrigated and rainfed hybrid maize farmers in Bangladesh with a crop and nutrient management guideline customized to the needs of the individual farmer. Maize Crop Manager uses farmer's answers to questions on his or her maize farming practices to automatically generate a maize crop management guideline aimed at increasing the farmer's net income on each field.

Maize Crop Manager is designed for use by extension workers, crop advisors, input providers, and agricultural service providers who interview a farmer using a computer or smartphone. After the interview, the collected information can be stored on the computer or smartphone until the device is connected to the Internet through a web browser. Collected information is then transmitted via the Internet to the Maize Crop Manager 'model', which calculates and transmits a crop management guideline within moments back to the computer or smartphone. 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 maize production.

The concept and framework for Maize Crop Manager was developed by IRRI. The nutrient management guideline provided by Maize 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. In Bangladesh, a long-standing collaboration between the International Maize and Wheat Improvement Center (CIMMYT) and the Bangladesh Agricultural Research Institute (BARI) allowed experts in maize cultivation from each organization to contribute technical content, and knowledge to Maize Crop Manager.

Research contributing to the development of Maize Crop Manager was made possible through support from the

• Australian Centre for International Agricultural Research (ACIAR) supported Rice-Maize project
• U.S. Agency for International Development (USAID) Mission in Bangladesh, through the Feed the Future supported Cereal Systems Initiative for South East Asia (CSISA) in Bangladesh
• European Union supported Agriculture, Nutrition, and Extension Project

In addition to BARI and CIMMYT, the following organizations contributed to the field evaluation of Maize Crop Manager:

• Bangladesh Rice Research Institute (BRRI)
• Bangladesh Academy for Rural Development (BARD)
• Rangpur Dinajpur Rural Services (RDRS)
• Department of Agricultural Extension (DAE)

Terms and conditions

Maize Crop Manager provides a crop and nutrient management guideline for maize in irrigated and favorable 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 inputs 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 Maize Crop Manager - such as climate and water availability - affect maize yield. IRRI does not guarantee a targeted 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.
