【 摘 要 】

Field experiments were conducted in Godean Subdistrict, Yogyakarta Special Region in June-August 2018, with Regosol soil type to evaluate the efficacy of the combination of active ingredients herbicide methyl metsulfuron, ethyl chlorimurone and natrium salt against rice weed growth at various doses of cow manure. The research was carried out by using a complete randomized block design with five doses of cow manure (0, 5, 10, 15 and 20 tons/ha) and control without application of herbicides and cow manure. They were applied at recommended doses at the 2- to 3-leaves. That weeds grown on the control are Monochoria sp, Ludwigia sp; Spenochlea sp, Mimosa invisa, Echinochloa sp, E. cruss galii, C. iria, and Fimbritilis. The higher the dose of cow manure shows the higher rate of weeds growth. There is a shift in weeds that can be controlled by herbicides with the same dose between low doses of cow manure and high doses. The herbicide application tested was effective in controlling broad leaf weeds at various doses of cow manure. The higher the dose of cow manure, the lower the efficiency of weed control.
