成果の概要

Field observations and harvests were conducted in two rice-growing regions of Madagascar to study the potential synergistic effect of the localized phosphorus (P) dipping technique and root system architecture on rice yield improvement. Plots with mature grains were sequentially harvested and grain yield and yield components were measured at the Radioisotopes Laboratory (LRI). Additionally, collected root samples were scanned for images, and analyzed to understand how changes in root architecture under localized P-dipping affect growth and yield in different rice genotypes.
