Abstract: There were two effects i. e. weed control and increasing field fertility, and obtaining 33% grain yield increase when Butachlor-Fertilizer(BF) was applied in transplanting rice. The reproductive capacity and concentration of soil ammoniated bacteria was limited and reduced significantly by BF of 112.5kg/ha. It was the most serious limit on soil microbial population when the BF applied during 7-14 days alter treatment (DAT). However, soil ammoniated bacteria recovered their reproduction at 28 DAT.
