The Effects Of Shade On Growth, Development And Yield Of A Primocane Fruiting Blackberry, ‘Prime-Ark 45’ To Extend The Market Season, Olivia C. Caillouet 2016 University of Arkansas

The Effects Of Shade On Growth, Development And Yield Of A Primocane Fruiting Blackberry, ‘Prime-Ark 45’ To Extend The Market Season, Olivia C. Caillouet

Horticulture Undergraduate Honors Theses

This thesis examines the effects of shade on ‘Prime-Ark 45’ blackberries (Rubus spp.) in greenhouse (GH) and field (FD) experiments aimed at improving fruit production in the southern United States Ozark Plateau region. Primocane blackberry production in the southern United States is limited in acreage of production as well as low yields by high temperatures during the bloom and early fruiting period, resulting in poor fruit set and poor fruit quality. Shade may have the potential to delay bloom and flowering to a more favorable season or by reducing temperatures that cause a poor fruit set and quality. Both the ...

Adapted And Non-Adapted Tropical Corn In Central Iowa: 2. Biomass Production And Composition, Pedro A. Infante Posada, Kenneth J. Moore, Sotirios V. Archontoulis, Andrew W. Lenssen, M. Paul Scott

Andrew W. Lenssen

Biomass production in the midwestern United States has largely been focused on corn (Zea mays L.) grain for ethanol production and more recently on corn stover for lignocellulosic ethanol. Corn production in this region is profitable and productive. As an alternative to conventional corn, tropical corn genotypes have been evaluated, but mainly for grain production; nevertheless, yields have fallen short of U.S. Corn Belt populations. Tropical corn is the term used for corn coming from tropical regions. Tropical corn has been adapted for early flowering for potential use in breeding programs under central Iowa conditions. Since adapted and non-adapted ...

Adapted And Non-Adapted Tropical Corn In Central Iowa: 1. Development, Growth And Quality Aspect, Pedro A. Infante Posada, Kenneth J. Moore, Sotirios V. Archontoulis, Andrew W. Lenssen, M. Paul Scott, Shuizhang Fei

Andrew W. Lenssen

Recent research has shown a high theoretical potential for ethanol production based on both stover and grain as sources, using lignocellulosic and fermentation processes respectively. Corn germplasm has been even broadly studied for grain production, but scant research has been done on current commercial cultivars in regards to biomass production. However, tropical corn germplasm, corn conventionally grown in tropical regions, has been studied as a potential source for biomass accumulation over grain. The comparison between tropical and temperate corn with a focus on biomass production has not yet been explored under Iowa day-length conditions.

This study identifies the adaptability of ...


Solutions To Soil Problems: Iii. Drainage, Michael Johnson, Rich Koenig 2016 Utah State University

Solutions To Soil Problems: Iii. Drainage, Michael Johnson, Rich Koenig

Michael Johnson

Drainage is a common problem throughout Utah. Complex patterns of soil development, transport and deposition have resulted in excessively drained soils that are coarse-textured (sandy or rocky), and poorly drained soils that are fine-textured (silt and clay-dominated). Excessively drained are more common in higher elevation and bench areas.


Efficient Irrigation Of Trees And Shrubs, Teresa A. Cerny, Kelly Kopp, Michael Johnson 2016 Utah State University

Efficient Irrigation Of Trees And Shrubs, Teresa A. Cerny, Kelly Kopp, Michael Johnson

Michael Johnson

In Utah, urban landscape irrigation accounts for 50-75% of the annual municipal water use, and much of it is applied in excess of the plant’s needs. This excess is a tremendous resource waste and the overspray causes substantial damage to hardscape (i.e., decks, patios, fountains, decorative concrete, etc.). Scheduling irrigation according to landscape plant water needs can reduce excess water use. In addition to conserving water, proper irrigation can encourage deeper root growth and healthier, more drought tolerant landscapes.

Estimating Consumers' Valuation Of Organic And Cosmetically Damaged Apples, Chenyan Yue, Helen H. Jensen, Daren S. Mueller, Gail R. Nonnecke, Douglas Bonnet, Mark L. Gleason 2016 Iowa State University

Estimating Consumers' Valuation Of Organic And Cosmetically Damaged Apples, Chenyan Yue, Helen H. Jensen, Daren S. Mueller, Gail R. Nonnecke, Douglas Bonnet, Mark L. Gleason

Helen Jensen

The sooty blotch and flyspeck (SBFS) disease complex causes cosmetic damage but does not affect the safety or eating quality of apples. Treatment for disease is more difficult and costly for organic producers, and consumers' willingness to pay for organic apples needs to be considered in growers' choice of production technologies. A mixed probit model was applied to survey data to evaluate consumers' willingness to buy apples. The results show consumers will pay a premium for organic production methods and for apples with low amounts of SBFS damage. Behavioral variables such as experience growing fruit significantly affect the willingness to ...

Anaerobic Soil Disinfestation: Meta-Analysis And Optimization Of Amendment Carbon Rate And C:N Ratio To Control Key Plant Pathogens And Weeds, Utsala Shrestha 2016 University of Tennessee, Knoxville

Anaerobic Soil Disinfestation: Meta-Analysis And Optimization Of Amendment Carbon Rate And C:N Ratio To Control Key Plant Pathogens And Weeds, Utsala Shrestha

Doctoral Dissertations

Anaerobic soil disinfestation (ASD) is an environmentally friendly and cost effective pre-plant soil treatment technique that allows effective control of soilborne pests by creating anaerobic conditions, particularly for specialty and organic crop production under diverse environmental conditions. In spite of being a proven technique, ASD has to be optimized to fit into local production systems with specific pathogen pressure using locally available amendments for successful implementation on a commercial scale. Our meta-analysis study on soilborne pathogens, plant parasitic nematodes, and weeds validated that ASD is an effective approach to control various soilborne pathogens. This study aims to optimize the carbon ...


Winter Greenhouse Production And Tissue Culture Of Basil (Ocimum Spp.), Wan Wei 2016 University of Nebraska-Lincoln

Winter Greenhouse Production And Tissue Culture Of Basil (Ocimum Spp.), Wan Wei

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Basil (Ocimum spp.) is a popular annual culinary and medicinal herb contains essential oils. Numerous researchers have studied the effects of fertilizer level on the growth and oil yield of basil, but in most studies, basil was grown in the field during the summer. Our experiment was conducted in a controlled environment greenhouse using a capillary mat system during the winter with a goal of increasing dry weight for fresh produce and basil essential oil. The 7-month experiment was conducted to determine the optimal production timeline and fertilizer levels for eight basil cultivars grown in a soilless mix. We found ...

Late Pre-Emergent Control Of Annual Bluegrass With Flazasulfuron & Indaziflam, J. Reeves, J. Hoyle

Kansas Agricultural Experiment Station Research Reports

All applications of flazasulfuron or indaziflam resulted in acceptable control of Annual Bluegrass (Poa annua), only allowing <3% visual weed cover (VWC) in all treatments compared to the non-treated (26% VWC) up to 133 days after application (DAA).


Influence Of Glyphosate Timings On Conversion Of Golf Course Rough From Tall Fescue To ‘Sharps Improved Ii’ Buffalograss, J. Reeves, J. Hoyle, D. Bremer, S. Keeley 2016 Kansas State University

Influence Of Glyphosate Timings On Conversion Of Golf Course Rough From Tall Fescue To ‘Sharps Improved Ii’ Buffalograss, J. Reeves, J. Hoyle, D. Bremer, S. Keeley

Kansas Agricultural Experiment Station Research Reports

All treatments, except the control that received no glyphosate application, resulted in acceptable buffalograss establishment (>90% buffalograss green cover) by 70 days after seeding (DAS). However, any treatment not sprayed prior to seeding date or that received a 7 DAS application lagged behind in establishment for 6 weeks after seeding.
