The new SRI world record in rice yield: what does it mean?

In November 2011, five Indian farmers broke the old world record in rice yield of 19.0 tons/hectare (380 cavans/ha), held by world-famous scientist Prof. Yuan Long-ping, inventor of hybrid rice.

The best of the five, Sumant Kumar, got a yield of 22.4 tons/ha, the new world record.

How did these five farmers beat the old world record? They all used a new method of growing rice, which they learned in 2008. The method is called System of Rice Intensification (SRI).

The new world record tells us three things about SRI:

ONE: SRI is farmer-friendly. Using it, ordinary farmers obtained a yield higher than the best rice scientist in the world could attain. They got a yield higher than IRRI, Philrice, or any other rice scientist has attained. With SRI, farmers can do better than scientists.

TWO: SRI leads to quick results. Prof. Yuan Long-ping had devoted almost 40 years of his professional to improving rice yield, and managed to go as high as 19.0 tons/ha. The five farmers learned SRI only in 2008. Within three years, they had broken Prof. Yuan’s record.

THREE: SRI is reliable. If only one farmer had broken the world record, we might hear comments like, “Tsamba!” (“Lucky break!”). If two or even three had done it, Doubts might persist among a few hardline skeptics. But with five SRI farmers, there is no doubt at all, that SRI is effective in improving rice yields.

We have been promoting SRI among farmers since 2000, long before it became the world record-holder in rice yield. With this development, there is no more reason for the government to keep ignoring this method.

Philippine SRI map: where are the SRI trainers, farm trials and trainings conducted so far

I have not been very active in posting messages lately because a particular advocacy has kept me really busy.

I coordinate SRI Pilipinas a national network of farmers and organic farming advocates that promote the System of Rice Intensification (SRI). I’ve made a few previous posts about this method, including the Nov. 2011 news that five SRI farmers in India have broken the world record in rice yield previously held by world-famous Prof. Yuan Long-ping, inventor of hybrid rice.

I am posting here two maps — 1) Luzon, and 2) Visayas and Mindanao — showing the areas where we have SRI trainers (who can conduct one-day trainings for free), where we have conducted one-day SRI trainings (almost 130 throughout the country so far), and where farmers have conducted SRI trials, as far as we know.

The maps may not show any place marker at first (teardrop-shaped icons) at first, because loading them takes time, especially over slow connections. Be patient. The man/woman icons stand for locations where we have SRI trainers.

Eventually we hope to have at least one SRI trainer in every rice-producing province.
