● P-dipping Rice Fertilizer Application Technique is Effective in Avoiding Flood Damage
P-dipping is a simple technique in which mud mixed with a small amount of phosphorus fertilizer is adhered to the seedling roots before transplanting.
This time, it was shown that this technique not only improved fertilizer use efficiency, but was also effective in preventing damage from flooding in the early stages of growth.

● Development of a new soybean variety with high Asian soybean rust resistance
In collaboration with Argentina's National Agricultural Technology Institute (INTA), a novel soybean variety named "Doncella INTA-JIRCAS" has been developed and officially registered in Argentina.
This variety was created through a crossbreeding process that strategically introduced three resistance genes to Asian soybean rust.
