Therefore, aquaponics has the potential to maximize food production with fewer resources, but the complexity and high capital costs of aquaponic systems have been hindering their use on a larger scale. Due to moderate commercial production there isn\u2019t much scientific literature on profitability of aquaponics. The aim of our study was to yield more science-based information on plant growth and quality in an aquaponic system, and to find out whether the source and fertilization of water affect them. We measured the growth of different edible plants in aquaponic and hydroponic systems, comparing both biologically relevant variables as well as variables related to capitalizing the crops: the fresh mass of the plants, the length and fresh mass of the roots, leaf area and the color, smell and taste of the plants. Our experimental setup included 12 tanks in which we cultivated and monitored two types (iceberg and Batavian) of lettuce (Lactuca sativa var. capitata) and red basil (Ocimum basilicum) for six weeks. We used two solution treatments in our study: the source of the water (two classes: bore well/aquaponics) and fertilization (added fertilizer/no fertilizer). Based on previous research we expected that the plants that received fertilizer would grow bigger than the plants that did not. Our results on the fresh mass of the whole plant, the fresh mass of the roots, the length of the roots and the leaf area supported this hypothesis. We also hypothesized that together the fertilizer and the water from aquaponic system would result in as good or even better growth than either one of them on their own. This hypothesis was supported by the results on the fresh mass of the whole plant, the fresh mass of the roots and the leaf area. Treatment did not have statistically significant effect on fresh mass or leaf area of basil, whereas comparing various variables Batavian lettuce grew larger than the other species. What can be seen as the most important result of this study is that no significant difference was identified in any of the variables measuring the growth and quality, nor in any of the plant species, between the plants cultivated in hydroponic and aquaponic solutions, i.e. fertilized bore well water and unfertilized water from the aquaponic system.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Jenni Sireeni (jejusire) on 2017-03-29 17:45:33.564903.
