Effect of the Effluent Waters from BFT Inland Aquaculture of the Growth and Functional Substance Contents in 3 Types of Vegetable Crops

Availability Verification of Effluent from BFT Inland Aquaculture for Urban Agricultural Fertilizer through Cherry Tomato Cultivation

“…As for SPAD that measures chlorophyll content in the plant body, there was no big difference in all plots except for the control plot. This result was similar to that of Kim et al (2016b) who conducted an experiment on cultivating eggplants, which also belong to solanaceae, using aquaculture effluents. It was also similar to Kim et al (2013) who cultivated cherry tomatoes using manure filtered liquefied fertilizer filtered after spraying pig manure slurry on manure like chaff and sawdust, and also to Ryoo and Seo (2008) who cultivated tomatoes using pig manure concentrate fertilizer.…”

Agricultural Recycling of BFT Inland Aquaculture Effluent for Blueberry ‘Duke’ Cultivation

“…These results do not coincide with those of an earlier study that the content of a functional substance in vegetables grown using effluent emitted from a BFT aquaculture farm was higher than that of vegetables grown using a conventional method (Kim et al, 2016b). Kim et al (2016b) reported that the content of anthocyanin in eggplant treated with the original and half-strength effluent from a BFT aquaculture farm was the highest, while the results of this study show that the content of anthocyanin in the HEW group was lower than that in the conventional group.…”

In another study on the accumulation of a functional substance in blueberry that was organically cultivated and grown using a conventional method (Wang et al, 2008), it was found that the content of a functional substance in blueberry organically grown was statistically significantly higher than that in blueberry grown using a conventional method.…”

“…Treatment with effluent from a BFT aquaculture farm is one way of organic farming. The content of anthocyanin in the QEW group was the highest, but that in the HEW group was similar to the control group in this study, which does not coincide with the results of earlier studies that the content of functional substances in tomato, pepper and eggplant grown using effluent from BFT aquaculture farms increased (Kim et al, 2016b;. In this regard, it is necessary to conduct a follow-up experiment on effluent from BFT aquaculture farms that affects the content of anthocyanin in blueberry more systematically, and to identify optimal levels of effluent for different plants or varieties.…”

“…Kim et al (2016a) pointed out that effluent from BFT aquaculture farms contains a variety of components that are useful for the growth of plants, such as organic nitrogen, phosphorus and potassium, and thus can be used to cultivate plants. In order to re-use effluent from BFT aquaculture farms in agricultural businesses, it was compared with chemical fertilizers that have been widely used to cultivate various vegetables such as lettuce, eggplant, pepper and tomato, and there was no significant difference between the effluent and chemical fertilizers, which proves its usability in agricultural businesses (Kim et al, 2016a;2016b;. These studies, however, designed experiments in actual farms to prove the effectiveness of fertilizers and mentioned the effectiveness of effluent from BFT aquaculture farms.…”
