irrespective of daylength effects. Our objective was to evaluate the effect of irradiance and daily light period on storage root yield and leaf elemental concentration of two sweetpotato cultivars grown hydroponically using the nutrient film technique (NFT

production methods in urban areas, food crops produced hydroponically in controlled environments can result in food that is accessible and of high quality ( Premanandh, 2011 ). The combined retail and wholesale value of food produced in a protected culture

basil ( Dou et al., 2018 ). The suitable DLIs for hydroponic lettuce production were recommended at 12.67 mol·m −2 ·d −1 ( Fu et al., 2017 ) and 14.40 mol·m −2 ·d −1 ( Zhang et al., 2018b ), respectively. However, few studies examined the relationships

; thereby the amount of fertilizer required in hydroponic production systems could be reduced. This is particularly important as the concentration of minerals in the nutrient solution is a key factor in the improvement of tomato fruit quality, affecting

similar to that reported by Shaw et al. (2001) for the Galia-type muskmelon cultivar Gal-152. Table 1. Mean early and total fruit yields, fruit size, and fruit quality of ‘Gal-152’ muskmelon grown hydroponically at varying plant densities in Fall 2001

hydroponic tomato production, increasing electrical conductivity (EC) of nutrient solution is a well-known technique to increase TSS of tomato fruit because the decreased osmotic potential (ψ S ) of nutrient solution restricts the water transport to fruit

There is an increasing need in hydroponic systems to recirculate and reuse nutrient solutions (NS) so as to avoid contamination of groundwater by fertilizer residues and reduce the production cost ( Gutiérrez et al., 2007 ; Van Os et al., 2008
