About Rice Crop Manager

Rice Crop Manager provides irrigated and rainfed lowland rice farmers in Indonesia 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 by an equivalent of US$ 100 per hectare per rice crop

Rice Crop Manager is designed for use by extension workers, crop advisors, input providers, and providers of services who interview a farmer using a computer or smartphone. After the interview, the collected information is stored on the computer or smartphone until the Web browser is connected to the Internet. Collected information is then transmitted via the Internet to the Rice Crop Manager 'model', which calculates and transmits a crop management guideline back to the computer or smartphone. Each guideline provides an actionable recommendation, 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.

Rice Crop Manager was developed from Nutrient Manager for Rice. The following organizations contributed to the formulation and field evaluation of Nutrient Manager for Rice, which is the precursor to Rice Crop Manager and provides the nutrient management component in Rice Crop Manager.

• Indonesian Center for Rice Research (ICRR)
• Indonesian Center for Food Crops Research and Development (ICFORD)
• Indonesian Center for Agricultural Land Resources Research and Development (ICALRD)
• Indonesian Center for Agricultural Technology Assessment and Development (ICATAD)

The nutrient management guideline provided by Rice Crop Manager is based on the principles of site-specific nutrient management (SSNM) as described in the following publication:

Fairhurst T, Witt C, Buresh R, Dobermann A (editors). 2007. Rice: a practical guide to nutrient management. Second edition. Los Baños (Philippines): International Rice Research Institute and Singapore: International Plant Nutrition Institute and International Potash Institute. Click here to view the publication.

The development of Rice Crop Manager was made possible through support from the

• Swiss Agency for Development and Cooperation (SDC)
• International Fertilizer Industry Association (IFA)
• International Potash Institute (IPI)
• International Plant Nutrition Institute (IPNI)

Terms and conditions

Rice Crop Manager provides a crop and nutrient management guideline for rice in irrigated and rainfed lowland environments of Indonesia. 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 Rice Crop Manager—such as climate and water availability—affect rice yield. 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 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.

Instructions for using Rice Crop Manager

1. To start, select on a language (Bahasa Indonesia or English). If it is your first time to access the Rice Crop Manager, this will be the first page you see. If not, you can access this with the button, located on the bottom left of the page, then click on Language.
2. Answer questions for the farmer's field in the order that they appear on the screen. A field could be one parcel or several parcels with similar management, variety, and soil fertility. Select an answer from a list of choices by clicking or ticking, or typing the answer into the provided box.
3. Use the scroll bar on the right side of the page with questions to go back to a previous question.
4. After all questions have been answered, click on the button that will appear on the bottom right of the page. If online, a recommendation page with the crop management guideline will be generated. This guideline is based on the answers to the questions. If offline, the user will be asked to save the collected information. The collected information will be saved as a pending input file. When connected to the internet, click on the button, click on the Pending input files folder then select the file to generate the recommendation.
5. The recommendation page typically provides a guideline for an attainable yield level higher than the yield previously attained by the farmer. The yield level is estimated as attainable with good agronomic management practices for the given variety, season, and location.
6. The recommendation page contains the following buttons:
   1. Save - for saving the recommendation
   2. Share - for sharing the recommendation as an e-mail or as SMS to the farmer's phone (This SMS feature is only available for smartphone users downloading Rice Crop Manager from the Android Play Store.)
   3. Print - printing the recommendation
7. The recommendation page can be printed as follows:
   1. For desktop or laptop computer: Click on the button below the recommendation page.
   2. For smartphone: Save the recommendation in the phone as an image. Connect phone to a computer connected to a printer. Find the image from the Gallery or File folder and then print.
8. To start developing a new recommendation, click the button and select Start new session.

Questionnaire for Rice Crop Manager

The questions used in Rice Crop Manager for interviewing farmers are available as a downloadable questionnaire, which can be printed.

The printed questionnaire can alternatively be used to interview farmers. The information collected with a questionnaire can then be entered into Rice Crop Manager to obtain a guideline for the interviewed farmer.
