This study was conducted to evaluate the effects of microbial and conventional chemical fertilizers on the growth of the radish(Raphanus sativus L.) and Chinese cabbage(Brassica campestris L.). Chemical fertilizer, microbial fertilizer, and combined one of them were applied after transplantation. Subsequently, microbial fertilizer was applied every 3 days. At 5 weeks after transplantation, plants were harvested for measurement of weight and length of the aboveground and underground parts. Fresh weight of the underground part in radish was greater in the combined application of chemical and microbial fertilizer (148.9g) than those of the chemical fertilizer(112.8g) or the microbial fertilizer(143.6g). Application of microbial fertilizer(160.3g) was more effective than that of chemical fertilizer(111.1g) on fresh weight of the aboveground part in radish. Fresh weight of the aboveground part in Chinese cabbage was greater in the combined application of chemical and microbial fertilizer(316.6g) than those of chemical fertilizer(225.7g) or microbial fertilizer(232.5g). Application of microbial fertilizer(2735.9cm²) was more effective than that of the chemical fertilizer(2387.5cm²) on the leaf area in Chinese cabbage. However, the largest increase in plant growth was found using the combined application of the chemical and microbial fertilizer. These data suggest that microbial fertilizer can be used to replace conventional chemical fertilizer as an eco-friendly fertilizer. Furthermore, the combined application of the chemical and microbial fertilizer greatly improves the growth of radish plants. These results suggest a new fertilization method to produce vigorous breeding materials in radish and Chinese cabbage. |
