The SATREPS project “Breakthrough in nutrient use efficiency for rice by genetic improvement and fertility sensing techniques in Africa (FY VARY Project)” organized a workshop, which also served as the mid-term evaluation of the project, at the Hotel Colbert in Antananarivo, Madagascar on December 12, 2019.
A bilateral meeting between Minister Lucien Ranarivelo of the Ministry of Agriculture, Livestock and Fisheries of Madagascar and JIRCAS President, Dr. Masa Iwanaga was held on August 30, 2019 for discussions on areas of research cooperation useful for further agricultural development of Madagascar in the future.
37.Contributing to food security in Madagascar by developing rice cultivation technology that improves fertilizer use efficiencyMadagascar is known for its rich ecosystem and rare flora and fauna, but it is less known that agriculture in this country is based on rice cultivation and rice consumption is more than twice as much rice as Japan. Meanwhile, rice productivity remains stagnant and has hindered poverty reduction in rural areas, making Madagascar one of the poorest countries in the world. Factors that impede rice productivity include the lack of money for fertilizer purchases due to poor farmers, and the poor nutrient environment resulting from weathered soil peculiar to Africa. Therefore, JIRCAS is conducting projects with local research institutes with the aim of developing technology that can improve rice productivity in a stable manner even under conditions where the nutrient supply from fertilizer and soil is small. As a recent research highlight, we developed a localized fertilizer management technique, phosphorus dipping that can efficiently increase rice yields under the typical rice-growing environment of the country.
Soil phosphorus availability for rice plants can be rapidly estimated by laboratory visible and near-infrared spectroscopy
