This experiment was conducted to investigate the effects and properties of organic materials, the fermented fowl droppings composts and the top viviparous malleatuses, utilizable for rice farming. At the 35th day after transplanting, the growth of rice plants was good in the order of organic farming, combined farming, conventional farming, and control plot. But stem number and dry weight of rice plant in organic farming decreased a little compared to those in conventional farming at the 65th day after transplanting. Rice yield decreased by 7% in organic farming and by 4% in combined farming compared to those of conventional farming. Weeding effect by inoculation of 5kg or 10kg of the top viviparous malleatuses per 10a was similarly 96% at the immediately inoculation after transplanting, 98.6% at the 7th days inoculation after transplanting and 70% at the 15th days inoculation after transplanting. By inoculation of 5kg per 10a at the 7th day and the 15th day after transplanting, rice yields decreased by 2% and 5%, respectively, compared to those of the conventional farming method. From the above results, it seems that the organic farming and the combined farming are useful and the inoculation of the top viviparous malleatuses is effective for control of weeds as the environmental preservation farming.
