Abstract

This experiments were conducted to investigate the effects of fertilizer for herbicides phytotoxicity of rice(Oryza sativa L. japonica cv Dongjin). The shoot and root growth of rice were inhibited more by pyrazosulfuron-ethyl or pyrazosulfuronethyl+molinate than bensulfuron methyl or bensulfuron methyl+dimepiperate application in nitrogen or nitrogen mixed solution. In phosphate or phosphate mixed solution, rice growth were inhibited more by bensulfuron methyl or bensulfuron methyl+dimepiperate than pyrazosulfuron-ethyl or pyrazosulfuron-ethyl+molinate application. In solution mixed with nitrogen and phosphate or fertilizer three elements, rice shoots were more. inhibited by pyrazosulfuron-ethyl or pyrazosulfuron-ethyl+molinate treatments, roots were inhibited more relatively by bensulfuron methyl or bensulfuron methyl+dimepiperate treatments. In all fertilizer solutions, rice plant heights were reduced by dimepiperate and molinate applications, but root growth was reduced only by nitrogen and phosphate mixed solution. Rice growth in sulfonylurea or their mixed herbicide application were more inhibited in high :nitrogen concentration arid by phosphate exclusion than by nitrogen exclusion culture.
