A computer simulation model for wastewater management in an integrated (fish production-hydroponics) system
… heat and nutrients can be recovered using hydroponics in a greenhouse attached to the recirculating aquaculture system facility. A computer model was developed to simulate system performance and to help determine design parameters for an integrated fish production-hydroponics system. The …

Root growth of wheat genotypes in hydroponics and soil in relation to water stress tolerance and grain yield
Root characteristics of wheat (Triticum aestivum L.) genotypes are believed to be important in tolerance to drought and flooding, yet neither the extent of differences in root size among modern soft red wheat genotypes, nor the degree of association between root size and drought or flooding …

Consumers’ Willingness to Pay for Hydroponic Lettuce
… controversy about the ongoing inclusion of hydroponics in the USDA organic program has highlighted uncertainty about marketing for hydroponic crops. In November 2017, the National Organic Standards Board voted not to recommend that hydroponic farms be banned from applying for organic …

Investigation of nutrient solutions for the hydroponic growth of plants
Hydroponics is used extensively in food production and plant research, allowing optimal control over the supply of elements to the plant. In hydroponics, nutrient can be delivered via a solution that is supplied to the growing plant or as a seed coat or treatment that is applied to the seed before …

A metabolomics-based approach to study abiotic stress in <em>Lolium perenne</em>
… order to study water-limitation a hydroponics system supplemented with polyethyleneglycol (PEG) was used to induce water-limitation for a period of one-week. A clear difference in the metabolic profiles of the leaves of plants grown under water stress was observed. Differences were …

Response of Arabidopsis to bacterial presence under iron stress
… bacteria under three different iron levels in a hydroponics system and measured the dry weight and chlorophyll content ten days post inoculation. This study aims to narrow the potential mechanism of the beneficial effects of bacteria on plants experiencing nutrient stress.

Phosphorus sensitivity in species of Proteaceae (Protea obtusifolia, Leucadendron coniferum and Leucadendron salignum) from different soil habitats : possible candidates for growth on former agricultural soils high in P
… lupins and Proteaceae. Kinetics of P uptake (in hydroponics) was determined at a range ( 4 to 2000 μM P) of P concentrations. Phosphorus sensitivity was relatively high in Ld. coniferum as evident from reduced growth, net photosynthetic rate, stomata} conductance and transpiration rates. Protea …

Phosphorous uptake rate in two low phosphorous updated species, Aspalathus linearis and Podalyria calyptrata
… and Aspa/athus linearis, were grown in hydroponics for 5 months at a low P supply of 4μM and P-depletion studies were conducted thereafter at 5 levels of external P (4, 10, 20, 50 and lOOμM). Growth rates (biomass accumulation) were also calculated as were root to shoot ratios for both …
