Influence of nitrogen form ratio and calcium on greenhouse and field performance of watermelon

Creator:: Lamb, Michael J.
Abstract:: Watermelon (Citrullus lanatus (Thunb.) Matsum. & Nakai var. Crimson Sweet) was seeded in a commercial peat mix in multicell containers (72 cells-tray⁻¹, 40 cm³-cell⁻¹) in July 1989 and April 1990. In 1989, the medium was amended with CaC0₃ at 10% w:v. In 1990, no CaC0₃ amendment was made. Watermelon seedling...

Characterization of Stormwater Runoff from a County Maintenance Facility and Evaluation of Temporal Performance of Bioswale in Its Treatment

Creator:: Gyawali, Kshitiz
Abstract:: In the last few decades, a lot of studies have been conducted to study about the quality of stormwater runoff from various sites and conditions. Highways, residential areas, and commercial sites are the focus of most of these studies while limited studies have done examination of stormwater from Maintenance and...
Resource Type:: Masters Thesis
Full Text:: quality for a range of parameters, including pH, EC, turbidity, TSS, TDS, VSS, PSD, hardness, Cu, Zn, P

Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...
Resource Type:: Masters Thesis
Full Text:: those with higher pH, and composts with EC > 2 dS∙m - 1 produced less root growth than those with

Methodologies to improve reliability engineering in early design

Creator:: O'Halloran, Bryan M.
Abstract:: This thesis is the summation of two publications with the motivation to move reliability analysis earlier in the design process. Current analyses aim to improve reliability after components have been selected. Moving specific analyses earlier in the design process reduces the cost to the designer. These early design analyses provide...

The design and evaluation of three "stream simulation" culverts in south central Oregon

Creator:: Reba, Michele L.
Abstract:: Three culverts, judged to be fish barriers, were replaced with "stream simulation" culverts on the Fremont National Forest of south central Oregon. The culvert sites are located in the Fort Rock Basin in streams that are home to resident Great Basin redband trout (Oncorhynchus mykiss). Great Basin redband trout is...

Requirements for successful irrigation systems in the Senegal River Basin (Mauritania)

Creator:: Abba, Fatima Zahra
Abstract:: Implementation of a small-scale irrigation project in southern Mauritania is analyzed in this report. The main objective is to demonstrate that small-scale irrigation farming is the best suited solution for Mauritania's agriculture. To reach this objective different steps are taken in this study. The first step highlights the different aspects...

The Underlying Differences in Greenhouse Gases (GHG) Emissions Control and Renewable Energy: Three European Countries Approaches to Policy

Creator:: Wilson, Kweku N.
Abstract:: "It appears that the summer of 2003 was very likely warmer than any other summer in Europe back to 1500" (Luterbacher, 2004). This was the conclusion of a study about the changing climate of Europe by climatologists at the University of Bern, Switzerland, and published in Science in May, 2004....

The effect of temperature on biochemical activities of embryo and seedling of germinating rice (Oryza Sativa L.) seed

Creator:: Luo, Shun
Abstract:: Some biochemical activities in embryo or seedling of germinating rice (Oryza Sativa L.) seed were studied to explain the effects of suboptimum (20 C), optimum (30 C), and supraoptimum (40 C) temperatures on seed germination and seedling growth. It was observed that 40 C slightly speeded up seed germination but...
Resource Type:: Masters Thesis
Full Text:: clover, ATP utilization was evident and the subsequent synthesis was rapid, resulting in a highest EC

Environmental Factors Affecting Phytophthora Root Rot of Rhododendron

Creator:: Mestas, Angie
Abstract:: Phytophthora root rot decreases availability and quality of rhododendrons produced in the USA. Symptoms of Phytophthora root rot include root necrosis, leaf chlorosis, stunting, and permanent wilt. The purpose of this thesis was to better understand the impact of root damage, soil moisture, nitrogen fertilizer application, and pathogen species on...
