Operational Policy Needs For Organic Agriculture Expansion In The Philippines: Focus On Vegetables, Agnes C. Rola, Blanquita R. Pantoja, Agnes R. Chupungco, Miriam R. Nguyen, Jaine C. Reyes, Guinevere T. Madlangbayan, Macrina G. Umali, Susan S. Guiaya, Eldy Z. Martinez, Gerdino G. Badayos

Journal of Public Affairs and Development

In 2010, the Philippines passed a law (Republic Act No. 10068) to support the expansion of organic agriculture (OA) in the country, with a goal of 5 percent of total production area being devoted to this technology. Available data show that in 2012, only about 0.7 percent of the agricultural land area in the country was devoted to OA production. While several other administrative orders supported the law, there seems to be a need to understand the processes to operationalize the said law.

This paper analyzed the production, marketing, and consumption issues surrounding the organic vegetable industry to come up …

Generation Of An Attenuated, Cross-Protective Pepino Mosaic Virus Variant Through Alignment-Guided Mutagenesis Of The Viral Capsid Protein, Godwill M. Chewachong, Sally A. Miller, Joshua J. Blakeslee, David M. Francis, Thomas Jack Morris, Feng Qu

School of Biological Sciences: Faculty Publications

Mild variants of many viruses are able to protect infected plants from subsequent invasion by more severe variants of the same viruses through a process known as cross-protection. In the past, the cross-protective viral variants were commonly derived from mild field isolates that were sometimes genetically heterogeneous, providing variable levels of crossprotection. Here, we report a novel approach to rapidly generate crossprotective variants of the tomato-infecting Pepino mosaic virus (PepMV) independently of the availability of mild field isolates. Our approach sought to attenuate PepMV by mutating less conserved amino acid residues of the abundantly produced capsid protein (CP). These less-conserved …

The Effects Of Economic Conditions On The Sport Horse Industry In Kentucky And Nationally, Elizabeth Lampert

Lewis Honors College Capstone Collection

The horse industry in Kentucky is larger than thoroughbreds and racing. Competing sport horses is an increasingly popular form of riding and showing in the bluegrass and nationwide. Sport horse disciplines include dressage, eventing, and hunter-jumper horses. In Kentucky, sport horse enthusiasts are fortunate enough to be near the Kentucky Horse Park, a park known worldwide for its shows and courses. In 2010, the park hosted the World Equestrian Games, marking the first time that the World Equestrian Games had been held outside of Europe. Focusing mainly on the bluegrass and the nation as a whole, the effects of the …

Determining Soil Texture By Feel, Edwin L. Ritchey, Joshua M. Mcgrath, David Gehring

Agriculture and Natural Resources Publications

Soil texture refers to the proportion of sand, silt, and clay in a soil. Texture influences almost every aspect of soil use, both in agricultural and engineering applications, and even how natural ecosystems function. Many scientists consider soil texture the most important soil property as it can influence soil/water relationships, gas exchange, and plant nutrition. Accurately determining soil texture in a lab requires time and money; therefore, it is often necessary to estimate soil texture in the field by feel, which can be very accurate if done correctly.

A Conjoint Analysis Study Of Preferences And Purchasing Behavior Of Potential Adopters Of The Bureau Of Land Management Wild Horses, Omotoyosi O. Adekunle

Theses and Dissertations--Agricultural Economics

This study uses conjoint analysis to examine the preferences of buyers for Bureau of Land Management (BLM) wild horses based on physical attributes of wild horses and individual characteristics of the buyers. Generalized ordered logit models and multinomial logit models are used to study the impact of the buyers’ demographic characteristics such as age, gender, knowledge about wild horse care, and number of wild horses previously adopted on physical attributes of the horses such as color, age, height, training status, temperament, conformation, and unique markings. Using a choice experiment, taken together, these attributes determine buyer’s preferences for a wild horse. …

Patch Burning: Implications On Water Erosion And Soil Properties, Altingul Ozaslan Parlak, Mehmet Parlak, Humberto Blanco-Canqui, Walter H. Schacht, John A. Guretzky, Martha Mamo

Department of Agronomy and Horticulture: Faculty Publications

Patch burning can be a potential management tool to create grassland heterogeneity and enhance forage productivity and plant biodiversity, but its impacts on soil and environment have not been widely documented. In summer 2013, we studied the effect of time after patch burning (4 mo after burning [recently burned patches], 16 mo after burning [older burned patches], and unburned patches [control]) on vegetative cover, water erosion, and soil properties on a patch-burn experiment established in 2011 on a Yutan silty clay loam near Mead, NE. The recently burned patches had 29 ± 8.0% (mean ± SD) more bare ground, 21 …

Perennial Geraniums, Sarah Browning

University of Nebraska-Lincoln Extension: Historical Materials

Hardy geraniums are a great ground cover plant for sunny or partially shaded areas, but they are often confused with the beautiful annual geraniums found at the garden center in spring. Technically, annual geraniums are in the genus Pelargonium, while the hardy geraniums are true geraniums. However, hardy geraniums are great perennial plants that deserve to be used more in Nebraska gardens.

Spatial And Temporal Dynamics Of Predator-Prey Interactions In Winter Wheat, Katelyn A. Kowles

Theses and Dissertations--Entomology

Aphids (Hemiptera: Aphididae) are pests of multiple cropping systems, primarily due to the viruses they vector and direct crop damage that is exacerbated by their rapid population growth. In Kentucky, grain aphids (Rhopalosiphum padi and Sitobion avenae) cause significant yield loss to winter wheat as vectors of Barley Yellow Dwarf virus (BYDV), prompting the routine application of insecticides. Coupled with increasing human populations and decreasing arable land, it is increasingly evident that biological control services provided by natural enemies represent a viable long-term management option. Aphids are preyed upon by a diverse array of predators that can be …

A Revision Of The New World And Select Old World Species Of Cremnops Förster (Hymenoptera: Braconidae: Agathidinae), Erika M. Tucker

Theses and Dissertations--Entomology

Parasitoid wasps are an important group of organisms in need of systematic revision. This dissertation examines the cosmopolitan parasitoid wasp genus Cremnops. It is a compilation of three projects and significantly advances the taxonomic foundation of the genus.

The New World species of the genus Cremnops are revised. Thirty-three species of Cremnops are treated; five are described as new, i.e., C. bertae sp. nov., C. cluttsis sp. nov., C. nymphius sp. nov., C. wileycoyotius sp. nov. and C. witkopegasus sp. nov. Six species are synonymized, i.e., Cremnops caribensis Berta 1998, is synonymized under C. guanicanus Wolcott 1924; C. nigrosternum (Morrison …

Stored Grain Pack Factors For Wheat: Comparison Of Three Methods To Field Measurements, Josephine M. Boac, Rumela Bhadra, Mark E. Casada, Sidney A. Thompson, Aaron P. Turner, Michael D. Montross, Samuel G. Mcneill, Ronaldo G. Maghirang

Biosystems and Agricultural Engineering Faculty Publications

Storing grain in bulk storage units results in grain packing from overbearing pressure, which increases grain bulk density and storage unit capacity. This study compared pack factors of hard red winter (HRW) wheat in vertical storage bins using different methods: the existing packing model (WPACKING), the USDA Risk Management Agency (RMA) method, and the USDA Farm Service Agency Warehouse Licensing and Examination Division (FSA-W) method. Grain bins containing HRW wheat were measured in Kansas, Oklahoma, and Texas. Packing was measured in corrugated steel bins and reinforced concrete bins with diameters ranging from 4.6 to 31.9 m (15.0 to 104.6 ft) …

Control System Development And Response Analysis Of An Electronically Actuated Variable-Orifice Nozzle For Agricultural Pesticide Applications, Joe D. Luck, Scott A. Shearer, Michael P. Sama, Santosh K. Pitla

Biosystems and Agricultural Engineering Faculty Publications

The goal of this research project was to further the development of an electromechanically controlled variable-orifice nozzle by creating an electronic control system and then evaluating that system based on step and ramp inputs. The control system was developed in a programming environment that combined an electronic data acquisition system and actuator with pressure and flow sensors. A proportional, variable-gain (based on system pressure) control system was developed to adjust nozzle flow rates to meet target application rates. The constraints were to achieve settling time of less than 1.0 s, overshoot of less than 10% of maximum flow (or minimum …

An Optical Sprayer Nozzle Flow Rate Sensor, Joseph S. Dvorak, Luke E. Bryant

Biosystems and Agricultural Engineering Faculty Publications

Ensuring proper flow rates from each nozzle on an agricultural sprayer has become even more important as advances continue to be made in precision application technology. In this article, we describe the structure and testing of a sensor technology based on optical cross-correlation to determine the flow rate of individual sprayer nozzles. An advantage of this technology is that it does not require that impellers or other components be placed in the flow, which could cause plugging. The only moving part in the entire system is a solenoid used to inject a tracer dye. The objective of this study was …
