PURPOSE: To efficiently culture a useful field crop by directly coating a seed, etc., with a microorganism belonging to Enterobacter and exhibiting a plant growth promotion effect and sowing it into the soil or by mixing the microorganism in the soil and subsequently sowing a seed therein.
CONSTITUTION: A microorganism [e.g. Enterobacter cloacae (Bikoken stipulation No. 1529)] belonging to Enterobacter and exhibiting a plant growth promotion effect is inoculated in a culture medium and cultured at 30°C and 240rpm for 24hr so as to prepare a seed mother culture solution. A seed (e.g. cucumber seed) is immersed in the resultant culture solution and the treated seed is sown in the soil not treated with the microorganism for raising of seedlings. Or, the microorganism is mixed in the soil and a seed, etc., is subsequently sown in the treated soil for raising of seedlings. Or, a seedling or a field crop is cultured in a fertilizer solution for nutriculture, containing the microorganism exhibiting the plant growth promotion effect according to the nutriculture method. Thus, the objective useful field crop can efficiently be cultured.
