The document summarizes on-farm trials of the System of Rice Intensification (SRI) conducted in Eastern Visayas, Philippines from 2004-2006. Key findings include average SRI yields being 2-4 tons/ha higher than traditional methods, with some farmers achieving over 13 tons/ha. Over 30 orientations introduced SRI to over 1,000 farmers. On-farm trials on over 50 sites demonstrated SRI's benefits, leading more farmers to adopt the method in subsequent seasons. The trials were conducted by agricultural agencies and evaluated SRI's yield increases and economic benefits compared to traditional rice cultivation.

11. The System of Rice Intensification Methodology 3. Available compost/manure in the area will be used as fertilizer to be applied before plowing or first harrowing. The rate of application will be dependent on the soil fertility and the resources of farmers. 4. Broadcast pre-germinated rice seeds (farmers’ choice) sufficient for the SRI plot (500 sq.m.)

13. The System of Rice Intensification Methodology 7. Two weeding operations, using rotary weeders, should be employed. First weeding should be 8-10 days after planting. Second should be approximately 3 – 4 weeks after planting. Hand weeding should follow during the growing/tillering phase.
