Nitrogen fertigation practices to optimize growth and yield of northern highbush blueberry (Vaccinium corymbosum L.)

Creator:: Vargas, Oscar L.
Abstract:: Northern highbush blueberry is a long-lived perennial crop that is well adapted to low soil pH conditions. The plants are often shallow rooted and absorb primarily the ammonium (NH₄) form of nitrogen (N) rather than nitrate-N (NO₃-N). Traditionally, commercial blueberry fields have been irrigated with overhead sprinklers and fertilized using...

Growth and Fruit Production of Highbush Blueberry Fertilized with Ammonium Sulfate and Urea Applied by Fertigation or as Granular Fertilizer

Creator:: Vargas, Oscar L. and Bryla, David R.
Abstract:: Fertigation with liquid sources of nitrogen (N) fertilizers, including ammonium sulfate and urea, were compared with granular applications of the fertilizers in northern highbush blueberry (Vaccinium corymbosum L. ‘Bluecrop’) during the first 5 years of fruit production (2008–12). The planting was established in Apr. 2006 at a field site located...

Irrigation and Fertigation with Drip and Alternative Micro Irrigation Systems in Northern Highbush Blueberry

Creator:: Vargas, Oscar L., Bryla, David R., Weiland, Jerry E., Strik, Bernadine C., and Sun, Luna
Abstract:: The use of conventional drip and alternative micro irrigation systems were evaluated for 3 years in six newly planted cultivars (Earliblue, Duke, Draper, Bluecrop, Elliott, and Aurora) of northern highbush blueberry (Vaccinium corymbosum L.). The drip system included two lines of tubing on each side of the row with in-line...

Growth and surface modification of LaFeO₃ thin films induced by reductive annealing

Creator:: Flynn, Brendan T., Zhang, Kelvin H. L., Shutthanandan, Vaithiyalingam, Varga, Tamas, Colby, Robert J., Oleksak, Richard P., Manandhar, Sandeep, Engelhard, Mark H., Chambers, Scott A., Henderson, Michael A., Herman, Gregory S., and Thevuthasan, Suntharampillai
Abstract:: The mixed electronic and ionic conductivity of perovskite oxides has enabled their use in diverse applications such as automotive exhaust catalysts, solid oxide fuel cell cathodes, and visible light photocatalysts. The redox chemistry at the surface of perovskite oxides is largely dependent on the oxidation state of the metal cations...

The Effect of Intensive versus Usual Blood Pressure Control on Kidney Function Among Persons With Prior Lacunar Stroke: A Post-Hoc Analysis of the Secondary Prevention of Small Subcortical Strokes (SPS3) Randomized Trial

Creator:: Peralta, Carmen A., McClure, Leslie A., Scherzer, Rebecca, Odden, Michelle C., White, Carole L., Shlipak, Michael, Benavente, Oscar, and Pergola, Pablo
Abstract:: Background—The effect of intensive blood pressure (BP) lowering on kidney function among individuals with established cerebrovascular disease and preserved estimated glomerular filtration rate (eGFR) is not established. Methods and Results—Among 2610 participants randomized to a lower (<130 mm Hg) versus higher (130–149 mm Hg) systolic BP target with repeated measures...

Endosperm Tolerance of Paternal Aneuploidy Allows Radiation Hybrid Mapping of the Wheat D-Genome and a Measure of γ Ray-Induced Chromosome Breaks

Creator:: Tiwari, Vijay K., Riera-Lizarazu, Oscar, Gunn, Hilary L., Lopez, KaSandra, Iqbal, M. Javed, Kianian, Shahryar F., and Leonard, Jeffrey M.
Abstract:: Physical mapping and genome sequencing are underway for the ≈17 Gb wheat genome. Physical mapping methods independent of meiotic recombination, such as radiation hybrid (RH) mapping, will aid precise anchoring of BAC contigs in the large regions of suppressed recombination in Triticeae genomes. Reports of endosperm development following pollination with...

Abstract:: Background: Having conquered water surfaces worldwide, the semi-aquatic bugs occupy ponds, streams, lakes, mangroves, and even open oceans. The diversity of this group has inspired a range of scientific studies from ecology and evolution to developmental genetics and hydrodynamics of fluid locomotion. However, the lack of a representative water strider...

Abstract:: Human alterations to nutrient cycles[superscript 1,2] and herbivore communities³⁻⁷ are affecting global biodiversity dramatically². Ecological theory predicts these changes should be strongly counteractive: nutrient addition drives plant species loss through intensified competition for light, whereas herbivores prevent competitive exclusion by increasing ground-level light, particularly in productive systems[superscript 8,9]. Here we...

Abstract:: Invasions have increased the size of regional species pools, but are typically assumed to reduce native diversity. However, global-scale tests of this assumption have been elusive because of the focus on exotic species richness, rather than relative abundance. This is problematic because low invader richness can indicate invasion resistance by...
