SRI In Summary : A set of principles and methods to get more productive PHENOTYPES   from  any existing GENOTYPE  of rice  It does this by  changing management   of  plants, soil, water, and nutrients  to (a) induce   greater ROOT growth   and (b) nurture  more abundant and diverse  populations of   SOIL BIOTA
TWO ALTERNATIVE PARADIGMS   ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
