  • This plot of Liu Zhibin’s was harvested just before my visit, with an official certificate for a yield of 13.4 t/ha. In 2001, when Liu first used SRI methods, on soil that has been kept well supplied with organic matter, he got a yield of 16 t/ha which helped to persuade Prof. Yuan Long-ping, ‘the father of hybrid rice’ in China, to become more interested in SRI. Liu is manager for the seed farm that produces hybrid seed for Prof. Yuan’s operations.
  • Here we look just at the effect of young seedlings, on better and poorer soil, at Anjomakely. The synergistic effect of compost with aerated soil is seen in the bottom three lines. Compost with saturated soil does less well (7.7 t/ha) than NPK with aerated soil (8.77 t/ha), but compost with aerated soil does by far the best (10.35 t/ha) on better soil. The same relationship is seen on poorer soil (right-hand column).

  • These data were reported in Prof. Robert Randriamiharisoa&apos;s paper in the Sanya conference proceedings. They give the first direct evidence to support our thinking about the contribution of soil microbes to the super-yields achieved with SRI methods. The bacterium Azospirillum was studied as an &amp;quot;indicator species&amp;quot; presumably reflecting overall levels of microbial populations and activity in and around the plant roots. Somewhat surprisingly, there was no significant difference in Azospirillum populations in the rhizosphere. But there were huge differences in the counts of Azospirillum in the roots themselves according to soil types (clay vs. loam) and cultivation practices (traditional vs. SRI) and nutrient amendments (none vs. NPK vs. compost). NPK amendments with SRI produce very good results, a yield on clay soil five times higher than traditional methods with no amendments. But compost used with SRI gives a six times higher yield. The NPK increases Azospirillum (and other) populations, but most/much of the N that produced a 9 t/ha yield is coming from inorganic sources compared to the higher 10.5 t/ha yield with compost that depends entirely on organic N. On poorer soil, SRI methods do not have much effect, but when enriched with compost, even this poor soil can give a huge increase in production, attributable to the largest of the increases in microbial activity in the roots. At least, this is how we interpret these findings. Similar research should be repeated many times, with different soils, varieties and climates. We consider these findings significant because they mirror results we have seen in other carefully measured SRI results in Madagascar. Tragically, Prof. Randriamiharisoa, who initiated this work, passed away in August, 2004, so we will no longer have his acute intelligence and probing mind to advance these frontiers of knowledge.
  • Tefy Saina is more comfortable communicating in French language, but it can communicate in English and reads English very well. CIIFAD maintains worldwide contacts on SRI through the internet. Queries are invited, directed to CIIFAD generally or to Norman Uphoff specifically. The SRI web page maintained by CIIFAD in cooperation with Tefy Saina has recent information on SRI experience in countries around the world.
