A biofertilizer, having been deordorized and showing promotive effect on plant growth, was manufactured from the rice straw and hen feces by use of Thermoactinomycetes vularis. This strain grew vigorously on rice straw mixed with unsterilixed hen feces at 50 deg C, pH 8.0-8.5 and moisture content of 60% and got rid hen feces of malodour during treatment. The growth of plant (Brassica rapa var. previdis) was experimented on humic volcanic ash soil, using pot in thermostatically controlled greenhouse. The biofertilizer was applied as N-fertilizer and air-dried hen feces or ammonium sulfate were used for comparison with the biofertilizer. The effect on plant growth was evaluated on the basis of the amount of nitrogen as fertilizer, under a loading of 0.1g N/pot, all samples showed a promotion effect of plant growth. But ammonium sulfate an air-dried hen feces inhibited plant growth at the nitrogen content over 0.2 and 0.4g N/pot, respectively, whereas the biofertilizer showed a good promotion effect on plant growth without growth inhibition even at nitrogen content of 0.8g N/pot
