| Outline of Final Research Achievements |
①The dry matter production after flowering, affected by the absorption of solar radiation during the flowering stage, was an important factor for increasing the number of pods and then the overall soybean yield. ②The amount of nitrogen absorbed by the beginning of seed filling was an important factor for increasing the number of seeds and then the overall soybean yield. ③Precision Crop Management for correcting the spatial variability of the dry matter production after flowering and/or the amount of nitrogen absorbed by the beginning of seed filling in the field and among the fields will correct the spatial variability of the soybean yield in the field and among the fields. ④ The new growth index that combines the chlorophyll index (CI) with measure of solar radiation (Σ(CI×I)) will contribute to effectively estimate the dry matter production after flowering and/or the amount of nitrogen absorbed by the beginning of seed filling.

| Academic Significance and Societal Importance of the Research Achievements |
日本のダイズ作は輪乾田で栽培され、その収量と品質は低く不安定です。その原因として、圃場内・圃場間における品質・収量の不均一性があります。本研究は、その不均一性を是正する栽培管理法を提案するものであり、ここに、学術的意義や社会的意義があると考えます。
