In order to investigate the effect of different nutrient solutions on yield and potato minituber production under aeroponic and hydroponic culture, a split-plot experiment based on completely randomized design with three replications was carried out in 2015. The main factor was culture medium (aeroponic and hydroponic) and the sub-factors consisted of nutrient solution (control, Etazu, Etazu+ h...

Abstract Although nickel (Ni) is known as an essential element for higher plants, the biological effects of this nutrient on growth, yield, and N metabolism of some plants, particularly leafy vegetables, is still unknown. Therefore, this study was carried out to investigate the effects of Ni and urea nutrition on the growth and yield of lettuce (Lactuca sativa L. cv. Baker) and urea accumulati...

Silicon (Si) has beneficial effects on the growth, yield, and tolerance of some crops against biotic and abiotic stresses. Considering the absence of Si in the nutrient solutions used in hydroponically-grown cucumber, the present study was conducted to investigate the influence of Si on the growth and yield of two cucumber genotypes (Cucumis sativus L. cvs. Dominus GRC and Super Dominus). In a ...

Silicon (Si) has not been considered as an essential nutrient for plant growth however, it has been shown that supplying crops with adequate Si can improve environmental stress tolerance. On the other hand, exposure to toluene, as a hazardous organic pollutant widely found in the water resources, is an environmental stress for plants growing around many industries. The aim of this nutrient solu...
