Some farmers of irrigated rice in Asia, Africa and the Americasare using a production method called S. R. I. ，which is short for theSystem of Rice Intensification. It does not require new seeds. It onlyrequires changes in the ways that rice farmers manage plants, soil, water and nutrients.
With S. R. I, farmers use fewer seeds and transplant themearlier than usual. Leaving more room between plants lets the rootsand leaves spread more. Farmers also use less water. They keep thefieldsmoistbut do not continuously flood them. The use of chemicalfertilizer is also reduced.
Norman Uphoff is a big supporter of S. R. I, who was a professor in New York. He retired but still works from an office there tobring attention to the system.
A French priest developed S. R. I. in Madagascar(马达加斯岛)in the 1980s. Norman Uphoff learned about it fifteen yearsago while working there. He led field trials for the system for threeyears.
He says it usually doubles productivity. But during that time inMadagascar, it produced an average of eight tons per hectare. Thatwas four times the usual average. In the late 1990s, Professor Uphoffbegan trying to spread the word about S. R. I.
Supporters say there have been reports from many areas oflarge increases in productivity and profits. But not everyone is persuaded.
Kenneth Cassman is an agricultural expert. In his words, "There is no strong evidence that the S. R. I. is more effective thanthe best of conventional rice-growing methods. " But Norman Uphofflooks forward to more field trials in 2009 which he believes willconfirm the effectiveness of S. R. I.
