In April 2026, JIRCAS released an introductory video and an infographic poster that clearly explain “P-dipping,” a fertilization technique developed as a research outcome of the “Africa rice farming system” project.
P-dipping is an innovative fertilization technique that improves phosphorus use efficiency in rice. It was developed through collaborative research between research institutions in Madagascar and Project Leader TSUJIMOTO Yasuhiro. This technology is one of the key achievements of the “Africa rice farming system” project under JIRCAS’s 5th Medium to Long-Term Plan, and it has attracted attention as a method to increase rice productivity while making effective use of limited resources.
JIRCAS aims to widely share the results of such international collaborative research with society and deepen understanding of their significance and value. To achieve this, the organization places importance on communicating research in ways that are visually and intuitively easy to understand. In this case, two different formats were used—a short introductory video and an infographic—to make the technical content more accessible.
The approximately four-minute video, titled A Simple Technique Boosts Rice Production in Africa | P-dipping – Dr. Tsujimoto (辻本泰弘）| JIRCAS, introduces the mechanism, features, and on-site effects of P-dipping, accompanied by footage from Madagascar. It includes Japanese and English narration and subtitles, making it easy for both researchers and the general public to understand.
Meanwhile, the infographic poster combines “information” and “graphics” to visually present the effects and advantages of P-dipping. With its colorful, approachable design and illustrations, it is crafted to help viewers intuitively grasp the interest and social value of the research. The poster is available in both Japanese and English and will be used on the website, as well as at exhibitions and events.
Please take a look at both the video and the poster to get a sense of the research that JIRCAS is conducting to contribute to the promotion of rice cultivation in Africa.
