Applying P and Zn fertilizer to promote rice yield has been common in Yunnan Province fora long time. We conducted an experiment atRice Res Inst of Yunnan Agri Univ, Kunming(25°N, 109°E, 1950°E msl) where the land islow in P and Zn, to observe the effects of Zn and P fertilizer on the grain yield and qualities of rice.
