1435 System of Rice Intensification - An Opportunity to Improve the Productivity and Resilience of African Rice Production

  1. 1. SYSTEM OF RICE INTENSIFICATION (SRI), AN OPPORTUNITY TO IMPROVE THE PRODUCTIVITY AND RESILIENCE OF AFRICAN RICE PRODUCTION Bagayoko, M1 ; Traoré, G1.; Styger, E2. Jenkins, D2. 1 Institut d’Economie Rurale BP 258 BAMAKO 2 Cornell University USA The System of Rice Intensification, or SRI, is an agro-ecological approach that allows farmers to increase yields while at the same time decrease inputs such as water, seeds, chemical fertilizers, herbicides and pesticides. While SRI was initially developed with irrigated rice, it has been adapted to rainfed lowland and upland rice systems, as well as to other crops. ( Liberia SRI Nigeria Plot, Jigawa State, Nigeria Mali Although the SRI practices can be adjusted according to local conditions, the four core principles for SRI, for any of the rice systems - irrigated or rainfed - remain the same: 1. Favor early, vigorous and healthy plant establishment 2. Minimize competition between plants 3. Create fertile soils that are rich in organic matter 4. Optimize water management by avoiding anaerobic soil conditions Field evaluations since 2002 across Africa indicate SRI yields range between 6-11 t/ha (average 7.5 t/ha). SRI crop stands adapt better to climate variability due to deeper and roots and improved phenotype.

It is coordinated by CNS-RIZ/IER in Mali and backstopped by SRI-Rice at Cornell University. Opportunities for large-scale adoption of SRI include: •Increasing commitment from high level decision makers •Existence of motivated and innovative farmers, the SRI champions •Existence of motivated extension services •Existence of researchers willing to accompany the dynamic 1.CORAF/WECARD: West and Central Africa Council for Agricultural Research and Development 2.WAAPP: West Africa Agricultural Productivity Program SRI SYSTEM MALI 2008-2012 4.5 7.4 GUINEA 2013 8.5 10.6 NIGERIA 2012 3.0 11.0 SENEGAL 2013 5.5 8.0 SIERRA LEONE 2013 1.8 6.7 TOGO 2012 2.7 5.6 2013 2.8 6.6 Liberia’s President Ellen Johnson Sirleaf during SRI Field Day and Launch Ceremony in Zubah Town, Monrovia, May 9, 2014 Conventional SRI SRI field at harvest (9 t/ha)
