Exploring the future of rice farming
The Robert S. Zeigler Experiment Station at IRRI (ZES) is the site where some of the world's most productive and important rice varieties are developed and first tested. Examples of these varieties are IR42, IR36, and IR8, which dramatically increased rice's yield potential, ushering in an exciting new era in Asian food security and rural development.
The ZES hosts research on high-nutrient rice that is seen as significant in helping people obtain enough important micronutrients through rice consumption and addressing major public health concerns now and in the future.
Our irrigation research looks at effectively managing either an abundance or lack of water in different environments. Through this research, more farmers in Asia now practice efficient irrigation scheduling and drainage management.
The system of alternate wetting and drying was developed to enable farmers to cut their water use as much as 30% without compromising their yields.
The ZES also hosts research activities on nutrient use and nutrient uptake of rice to make the best use of both organic and inorganic fertilizer.
The ZES is committed to reducing environmental costs and maximizing environmental benefits from rice farming. It has an environment management system that focuses on reducing energy use, pesticide use, and emissions while improving air quality and waste management.
Pesticides are used sparingly following globally accepted application protocols. We choose pesticides that have short residual periods in the environment and that are approved for commercial use by the Philippine Fertilizer and Pesticide Authority.
