Rice is the most important food crop in the Philippines and is a staple in most parts of the country. It is produced extensively in Luzon, the Western Visayas, Southern Mindanao, and Central Mindanao, accounting for 2.8% of global rice production and making the Philippines the eighth largest producer of rice in the world.

Filipino researchers have developed a tool called palay quality checker, an automated system that can detect nitrogen deficiency in the rice leaf using color image processing that is embedded in a mobile unit running on Android technology. The color of palay leaves indicates whether a crop is healthy or not. Using the palay quality checker, an image of a rice leaf is tested using pixel value threshold count compared against PhilRice's leaf color chart standards.


IRRI Seminars are a forum for invited IRRI staff and guests to present information and their opinions on topics relevant to international rice research and the work of IRRI.
