System of Rice Intensification

Another project for research this monsoon

Thanks to Jakob, who’s research we will also be using.

What is SRI?

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 an agro-ecological methodology for increasing the productivity of irrigated rice by changing the management of plants, soil, water and nutrients. SRI originated in Madagascar in the 1980s and is based on the cropping principals of significantly reducing plant population, improving soil conditions and irrigation methods for root and plant development and improving the plant establishment methods.

Benefits of SRI

The benefits of SRI, which have been demonstrated in over 40 countries (see map). They include: 50%-100% or more increased yield, up to 90% reduction in required seed, up to 50% savings in water. SRI principals and practices have been adapted for rainfed rice as well as for other crops such as wheat, sugarcane and teff, among others, with yield increases and associated economic benefits.

Basic SRI methods include:

  • Carefully transplant single seedlings at two-leaf stage (8-12 days)
  • Plant seedlings at a distance of 25 cm or more in a square pattern
  • Keep soil moist and aerated. Fertilize naturally
