Water and Nutrient Reuse within Closed Hydroponic Systems
… research exists on the maintenance of individual nutrient balance within the nutrient solutions of closed hydroponic systems and how this maintenance may result in reductions in water and nutrient consumption. In this study, a nutrient solution management procedure was developed to maintain …

The Risk Of Pythium Aphanidermatum In Hydroponic Baby-Leaf Spinach Production
… is so prevalent that even crops grown in fresh nutrient solution will often show signs of Pythium damage at harvest time. Previous studies have identified nutrient solution temperature as a key factor in determining the growth and development of Pythium. The goal of this study was to estimate …

Influence of Seed Treatment on Tobacco Mosaic Virus Incidence in Tobacco Seedlings and Virus Distribution in Greenhouse Transplant Production
… one hundred years. Seedlings, seed coats, and nutrient solution were assayed for the presence of the virus and seed treatments were tested on seeds. Double antibody sandwich enzyme-linked immunosorbent assay (DAS ELISA) and biological local lesion assay data were collected. Seed coats from seed …

EVALUATION OF SEED TREATMENTS ON THE NODULE COMPETENCY OF SOYBEAN INOCULANTS
… broth culture. Iron supplement to the inoculum nutrient solution significantly increased the total biomass of nodules formed by strain KNI-1 but not by strain KNI-3 on a per plant basis and had no effect on the nodule number regardless of B. japonicum strain. In the glass bead viability study, …

An 15N study of the effects of nitrate, ammonium, and nitrate + ammonium nutrition on nitrogen assimilation in Zea Mays L.
… The use of a gravel rooting medium with nutrients recycling through the rooting medium, and an iron supplement in the form of ferric citrate, resulted in superior growth of nitrate-fed plants in comparison to that observed with a hydroponic growth technique and a standard Long Ashton …

Physiological responses of soybean seeds (Glycine Max L. Merr.) to metal pollutants
… were grown to maturity in a circulating nutrient solution system, which in the case of treatment plants, was amended with either Cd or Ni. From the results of preliminary trials in which the effect of metal pollutant concentration on plant growth and pod production were examined, nutrient …

Nitrate carrier induction and characterization in maize root plasma membrane using chlorate-36 as a radiotracer analog for nitrate
… plants are transferred to a nitrate containing nutrient solution. Whether this phenomenon reflects a change in nitrate carrier activity at the membrane level or an effect of nitrate metabolism has not been determined as yet due to the complexity of investigating nitrate transport with intact …

Anatomical, developmental and physiological aspects of silica in wheat
… of T. aestivum was reduced by silica in the nutrient solution (Si+) during the first six days of growth, compared to plants grown in solution not supplemented by silica (Si-), After a further four days Si+ plants had significantly longer roots than Si- plants. At the light microscope level, a …

Alfalfa growth on acid soil as influenced by Al, Ca, pH and Mo
… possibly as a result of Al activities in soil solution being as low as 0 and 0.05 uM in the surface and 1 m depth samples, respectively, for the surface limed soils. Low activity of Al in soil solution may explain why subsurface acidity was not toxic to alfalfa grown on these soils. This study …

The effects of growth salinity and irradiance on thylakoid stacking in lettuce plants
… such a way that the moderate salinization of the nutrient solution was associated with less stacking at high irradiances and more stacking at low irradiances, both relative to controls.

Phosphorus nutrition of Ilex crenata 'Helleri' grown in a pine bark medium
… When ‘Helleri’ holly were fertilized with a nutrient solution without P, 0.08 mg of indigenous P were absorbed. The pine bark adsorbed 7.5 µg of P per g of pine bark when equilibrated with a 10 ppm P nutrient solution. These studies indicate that maintaining 10 ppm P in the pine bark medium …

Absorption, translocation, and fate of the herbicide, 2-(3,4- dichlorophenyl)-4-methyl-1,2,4-oxadiazolidine-3,5-dione, in cotton
… Absorption into roots of 30-day-old plants via nutrient solution was rapid; translocation into stem and leaves occurred 12 to 24 hr after treatment. Radioactivity was translocated more rapidly in 40-day-old plants. ¹⁴C in leaves of root-treated plants was first located in the veins, then …
