The purpose of this article is to investigate the applications of hydroponic wastewater management systems (HWMS) as wastewater treatment facilities for the Dead Sea vicinity. In addition, it aims at managing the wastewater through generating commercially valuable plants using a proposed HWMS. A commercial hydroponic system was adapted for studying the potential heavy metals removal from primar...

Root zone high-temperature stress is a major factor limiting hydroponic plant growth during the high-temperature season. The effects of root zone cooling (RZC; at 25°C) and exogenous spermidine (Spd) root-pretreatment (SRP, 0.1 mM) on growth, leaf photosynthetic traits, and chlorophyll fluorescence characteristics of hydroponic Lactuca sativa L. grown in a high-temperature season (average tempe...

It is widely acknowledged that plant-made pharmaceuticals (PMPs) offer numerous benefits, including inexpensive production, biological safety and the facility for production at agricultural scale. At the same time, it is important to minimize any potential risk associated with this new technology, including the potential release of bioactive proteins into the environment. To address this issue,...

A series of trials have been conducted to evaluate the efficacy of Vetiver growing under hydroponic conditions to treat motel effluent, which has been primary treated in septic tanks. Water quality results and management issues are of interest. The aim is to surface irrigate the motel gardens with the treated effluent in a sustainable way. This can be accomplished if excessive nitrogen does not...

Environmental stresses frequently decrease plant fertility. In Arabidopsis, the effect of salt stress on reproduction was examined using plants grown in hydroponic medium. Salt stress inhibited microsporogenesis and stamen filament elongation. Because plants grown in hydroponic media can be rapidly and transiently stressed, the minimum inductive treatment to cause ovule abortion could be determ...

The land, water, and energy requirements of hydroponics were compared to those of conventional agriculture by example of lettuce production in Yuma, Arizona, USA. Data were obtained from crop budgets and governmental agricultural statistics, and contrasted with theoretical data for hydroponic lettuce production derived by using engineering equations populated with literature values. Yields of l...

Drought is one of the major environmental problems in agricultural field worldwide. The present study investigated the effects of water deficit caused by exogenous application of polyethylene glycol (PEG) on cabbage (Brassica oleracea var. capitata) grown in hydroponic culture. Root length, shoot length, dry weight, and relative water content of the seedlings significantly decreased in dose dep...

Vectobac G (Bacillus thuringiensis israelensis) application at 1.08 and 0.54g/ m to subirrigated pot and suspended forestry tube methods of non-circulating hydroponics in an unreplicated experiment greatly reduced numbers of Asian tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae), larvae and pupae compared to non-treated controls. Both Vectobac G rates, however, reduced lettuce head...

the present research was carried out under hydroponic culture to evaluate the interaction between salicylic acid (sa), nickel (ni) on vegetative and reproductive growth of strawberry plants as a factorial experiment in a completely randomized design. well-rooted daughter plants of pajaro cultivar, were potted in 3 l plastic pots and were sprayed with sa at concentrations of 0, 1, 2 and 3 mm and...
