"Africa rice farming system"
Development of sustainable rice cultivation and food production system in Africa

Related Research Program



Sub-Saharan Africa is the world's most food insecure region, with one in four people chronically hungry. In order to secure a stable supply of food for the region and achieve the eradication of hunger set forth in the SDGs, food production technology that can adapt to the increasingly unstable growing environment and effectively utilize limited resources such as water and nutrients is required. To this end, we will create new technologies and knowledge that will lead to increased production of rice, a key crop in the region, and improved nutrition for the people, with the aim of building a sustainable food production system centered on rice cultivation.

Rice productivity is limited due to unstable water conditions, degraded soils with poor nutrient supply, and low fertilizer inputs by farmers.


Develop new technologies and knowledge that will lead to a sustainable and nutrition-sensitive food production system centered on rice by integrating water management technologies, breeding materials and cultivation technologies, and to provide them to the target countries.


Development of breeding materials with enhanced adaptability to unstable production environments, improved nutritional quality and marketability

    849. Enhanced Rice Root Morphology Increases Phosphorus Uptake

    Phosphorus, one of the three main plant nutrients, is closely linked to plant growth and yield. It is therefore essential to provide plants with sufficient phosphorus. However, many agricultural areas around the world are deficient in phosphorus, and in developing regions such as Africa, economic constraints make it difficult to purchase enough fertilizer. As a result, crops often suffer from chronic phosphorus deficiency. Through genetic analysis of two rice varieties with contrasting root shapes, JIRCAS has discovered genetic loci that control lateral root development and the number of crown roots in rice, and has shown that these genes play a role in increasing phosphorus uptake by plants in phosphorus-deficient fields. The results of this research are expected to lead to improved rice yields in developing regions where phosphorus deficiency is widespread, and to reduced fertilizer application as a result of improved phosphorus use efficiency in rice.

    841. Table Salt for Soil Analysis ! ?

    Soils have a unique property called "phosphorus (P) retention capacity," which refers to their ability to bind with phosphates. When soil has a high P retention capacity, the P fertilizer applied in a cropland may bind to the soil before being absorbed by crops. This reduces the efficiency of fertilization. Therefore, P retention capacity is used for fertilization management. Recent studies have shown a close relationship between P retention capacity and soil moisture content. A research team from JIRCAS and the University of Antananarivo in Madagascar used this relationship to develop a method that accurately and easily estimates P retention capacity from soil moisture content, including a clever use of table salt (sodium chloride).

    789. Energy Intake and Seasons

    One component of food security is stability, and seasonality is a major factor affecting food security, especially for smallholder farmers in developing regions. Even if food is available immediately after harvest, it may not be available before the harvest season.
