Aquaponics, the portmanteau of “aquaculture” and “hydroponic”, is a sustainable food production system that combines the raising of aquatic animals such as fish in tanks (i.e. aquaculture) with the cultivation of plants in water (i.e. hydroponics) in a symbiotic environment [1]. In this paper we describe a new visualization approach that allows aquaponic gardeners to quickly monitor the status ...

Electrical resistances of roots and stems of hydroponically raised willows (Salix schwerinii) were studied and related to root morphology. Willow cuttings with and without roots were set in a constant electric field (effective voltage of 0.1 V, sine-AC, 128 Hz) in a hydroponic solution. The electrical resistance of different components in the measurement system was measured and analysed in rela...

The purpose of this study is to exploit the euryhaline nature of commercially attractive species for their cultivation in freshwater aquaponic systems. This approach may increase the profitability of aquaponic production in coastal countries where the consumption of marine fish is traditional and of commercial relevance. For this purpose, juvenile European sea bass (Dicentrarchus labrax) were r...

Potato is one of the staple crops cultivated in upland farming in Japan and is propagated vegetatively by means of tubers. However once infected with diseases, potato yield decreases significantly. And one seed potato can produce approximately only 10 potato tubers. To improve the production system of seed potatoes in Japan, Japanese government established a three-stage propagation system for t...

The amount of secondary metabolites in plants can be enhanced or reduced by various external factors. In this study, the effect of strontium ions on the production of phytoestrogens in soybeans was investigated. The plants were treated with Hoagland's solution, modified with Sr(2+) with concentrations ranging from 0.5 to 3.0 mM, and were grown for 14 days in hydroponic cultivation. After harves...

Metabolomics analysis of wild type Arabidopsis thaliana plants, under control and drought stress conditions revealed several metabolic pathways that are induced under water deficit. The metabolic response to drought stress is also associated with ABA dependent and independent pathways, allowing a better understanding of the molecular mechanisms in this model plant. Through combining an in silic...

Hydroponics is an alternative plant cultivation system that used without soil. This quite popular with the community, especially after Covid-19 pandemic. Many hydroponic gardens exist and survive d today. Consumer preferences behavior to consume vegetables are certainly important for farmers develop their business. It know consumer of vegetables. By knowing this, will be able formulate strategi...
