SRI METHODOLOGIES

 

The System of Rice Intensification, known as SRI -- le Système de Riziculture Intensive in French and la Sistema Intensivo de Cultivo Arrocero (SICA) in Spanish -- is a climate-smart, agroecological methodology for increasing the productivity of rice and more recently other crops by changing the management of plants, soil, water and nutrients.

SRI Principles

SRI methodology is based on four main principles that interact with each other:

Based on these principles, farmers can adapt recommended SRI practices to respond to their agroecological and socioeconomic conditions. Adaptations are often undertaken to accommodate changing weather patterns, soil conditions, labor availability, water control, access to organic inputs, and the decision whether to practice fully organic agriculture or not. The most common SRI practices for irrigated rice production are summarized in the following section.

In addition to irrigated rice, the SRI principles have been applied to rainfed rice and to other crops, such as wheat, sugarcane, teff, finger millet, pulses, showing increased productivity over current conventional planting practices. When SRI principles are applied to other crops, we refer to it as the System of Crop Intensification or SCI (see SCI section of the website for details).
