Welcome to IRRIís

Rice Production Course!


Rice is Asiaís economically and culturally most important food crop and its production is regarded as the single most important economic activity on the planet. More than 2.7 billion peopleómost of them poorórely on rice as their major source of food. By the year 2025, this number will grow to 3.9 billion people.


In the last four decades, the International Rice Research Institute (IRRI) has dramatically demonstrated that rice yields in Asia can be increased by applying scientific principles and new technologies. For example, the use of modern varieties and improved cultural practices have increased rice yields throughout tropical Asia.


Although the average yield per area did increase tremendously in the last forty years, the yield gap between economically optimal and actual yields remains large in many farmersí fields and in many countries. This yield gap may be caused by unfavorable environmental conditions and limited material inputs, but inefficient production technologies and lacking knowledge contribute greatly.
