Nutrient Solution and Solution pH Influences on Onion Growth and Mineral Content

Iron efficiency of different corn hybrids grown in nutrient solution culture

“…For corns, a modified half-strength Hoagland's nutrient solution was used consisting of (in mM) the following: Ca, 2.0; K, 3.0; N, 8.0; P, 1.0; Mg, 0.5; S, 0.5; Na, 0.05; Cl, 0.05; B, 0.025; Zn, 0.002; Cu, 0.0005; Mn, 0.002; and Mo, 0.0005 (Kane et al 2006). The two-leaf seedlings were grown in a nutrient solution with ventilator system at two Fe levels including 5 and 50 µM Fe-EDTA (Fe-ethylenediaminetetraacetic acid).…”

Ion-Specific Nutrient Management in Closed Systems: The Necessity for Ion-Selective Sensors in Terrestrial and Space-Based Agriculture and Water Management Systems

“…Each particular nutrient has its own effects on the plant and their individual activities can have a very strong influence on plant growth and health. If a particular nutrient is deficient, plant yields can be negatively affected [4,27–29]. A similar reduction in plant growth can arise when a particular nutrient is present at a concentration that is too high.…”

“…Further reasoning for the criticality of ion-selective sensors includes: Nutrient requirements vary among crops [2,27,29,30]Nutrient requirements change over the lifetime/growth phase of a given plant [4,30–35]Nutrient requirements fluctuate with changing environmental conditions [30,33,36]There exist several key nutrient ion ratios that must be maintained within the nutrient solution [29,30]. …”

Assessing Selection Parameters for Improving Yield in Organically Grown Onion

“…Numerous studies confirmed the effect of different nutrient regimes on important onion traits, such as postharvest attributes (Kumar et al, 2007), all in content (Bloem et al, 2004), growth and mineral content (Kane et al, 2006), pungency and yield (Guo et al, 2006). Examining winter garlic rust (Puccinia spp.)…”
