Agronomic And Economic Implications Of Cover Crop Inclusion Within Varying Nitrogen Management Strategies In Central Illinois, Richard T. Roth

Theses and Dissertations

This thesis contains a comprehensive analysis of research investigating the impacts of nitrogen application timing and cover crops on the biomass production, nitrogen uptake, and cash crop grain yield in subsequent cash crops. Also contained within this thesis is a cost benefit analysis for the implementation of cover crops within varying nitrogen management systems, which assigns value to the environmental benefits of cover crops and determines their potential to recover the implementation costs associated with cover crops.

Impacts Of Corn Price And Imported Beef Price On Domestic Beef Price In South Korea, Gwanseon Kim, Tyler Mark

Agricultural Economics Faculty Publications

South Korea is one of the largest beef importing countries in the world. Australia, USA, and New Zealand provide the majority of beef they import. The objective of this study is to evaluate the price relationship of Korean cattle and corn, prices of the imported beef and corn, and prices of Korean cattle and imported beef. We examine threshold points using threshold vector autoregressive (TVAR) model by assuming the presence of nonlinearity. We find that there are two thresholds in Australian beef price with first difference data. This study finds that the current Korean beef price is positively affected by …

The Influence Of Health Concern On Travel Plans With Focus On The Zika Virus In 2016, Nicole Olynk Widmar, S. R. Dominick, Audrey Ruple, Wallace Tyner

Department of Agricultural Economics Faculty Publications

Tourists consider many factors, including health, when choosing travel destinations. The potential for exposure to novel or foreign diseases alone can deter travelers from selecting high-risk locations for disease transmission. The 2015–2016 Zika Virus (ZIKV) outbreak in the Americas and Caribbean prompted the World Health Organization (WHO) to declare a Public Health Emergency of International Concern. This study investigated factors that may contribute to travel avoidance to areas experiencing ZIKV transmission while also considering different levels of health concern and awareness among groups with varying demographics. An online survey was administered February 10–12, 2016 to a sample of U.S. residents …

Biotic And Abiotic Factors Predicting The Global Distribution And Population Density Of An Invasive Large Mammal, Jesse S. Lewis, Mathew L. Farnsworth, Christopher L. Burdett, David M. Theobald, Miranda Gray, Ryan S. Miller

Other Publications in Wildlife Management

Biotic and abiotic factors are increasingly acknowledged to synergistically shape broad-scale species distributions. However, the relative importance of biotic and abiotic factors in predicting species distributions is unclear. In particular, biotic factors, such as predation and vegetation, including those resulting from anthropogenic land-use change, are underrepresented in species distribution modeling, but could improve model predictions. Using generalized linear models and model selection techniques, we used 129 estimates of population density of wild pigs (Sus scrofa) from 5 continents to evaluate the relative importance, magnitude, and direction of biotic and abiotic factors in predicting population density of an invasive large mammal …

Effect Of Organic And Inorganic Fertilizers On Soil Properties And The Growth, Yield And Quality Of Tomato In Mymensingh, Bangladesh, M. Ashraful Islam, Sumiya Islam, Ayasha Akter, Md Habibur Rahman, Dilip Nandwani

Agricultural and Environmental Sciences Faculty Research

Field trials were conducted on tomato for yield and quality of fruits using different types of organic and inorganic fertilizers at the horticulture farm of Bangladesh Agricultural University (BAU), Mymensingh. Fertilizer treatments were tested on two varieties of tomato ca. Roma VF and BARI 15. The fertilization treatments were T1, vermicompost (12 t/ha); T2, compost (10 t/ha); T3, integrated plant nutrient system (IPNS) or mixed fertilizers (organic 2/3 part and inorganic 1/3 part); T4, inorganic fertilizers; and a control (T5). Results showed growth and yield (20.8 t/ha) in tomato were higher in the IPNS treatment. A higher number of fruits …

The Effect Of Lupinus Albus On Growth Performance, Body Composition And Satiety Hormones Of Male Pigs Immunized Against Gonadotrophin Releasing Factor, Karen Moore, Bruce Mullan, Jae Cheol Kim, Frank R. Dunshea

Animal production and livestock research articles

Two hundred and ninety four pigs were used with the aim to develop a dietary management strategy using Lupinus albus L. (albus lupins) to reduce the increase in feed intake and subsequent increase in carcass fatness in pigs immunized against gonadotrophin releasing factor (immunocastrates; IC males) and entire male pigs in the late finishing stage. From day (d) 0 to 28, IC males fed the control diet grew faster (p = 0.009) than entire males fed the control diet but there was no difference in growth rate between sexes for pigs fed albus lupins for 14 days pre-slaughter (Albus 14) …

Effect Of Wet Brewer's Grain Inclusion On The Growth Performance, Carcass Performance, And Meat Quality Of Finishing Cattle, Riley T. Parmenter

Theses and Dissertations

The objective of this study was to determine the effects of Wet Brewer’s Grains (WBG) on the growth performance, carcass performance, and meat quality of finishing cattle. Twenty-four (n=24; 12 heifers – 303kg, 12 steers – 346kg) calves of Simmental-Angus genetics were utilized. Calves were paired by sex, blocked by BW within sex in a 2 x 2 factorial arrangement with three replications per treatment, and fed for 140d. Control diets were a conventional corn silage – shelled corn finishing-diet. Experimental diets modeled the control diet with the inclusion of WBG on a thirty-percent DM basis. Cattle were visually appraised …

Yield Gains In Dry Beans In The U.S., George Vandemark, Mark A. Brick, James D. Kelly, Juan M. Osorno, Carlos A. Urrea

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION Yield Gains can be estimated by comparing On-Farm yields vs. Potential yield (a.k.a., realized yield) or measured in common trials. The difference between On-Farm yield and Potential yield is known as the Yield Gap. Plant breeders primarily focus on increasing Potential yield while also attempting to optimize the interaction between genotype, environment, and agronomic practices to increase On-Farm yield and reduce the Yield Gap. In recent years, scientists in developing countries and the U.S. have made major advances in dry bean disease resistance, stress tolerance, and increased yield (Kelly, 2004). Agronomic and biotechnological tools have contributed to these achievements. …

Testing A Differential Set Of Andean And Mesoamerican Common Bean Genotypes To Characterize Rhizobium Isolates, Juan C. Rosas, D. Valle, C. Estevez De Jensen, J. S. Beaver, T. G. Porch

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

INTRODUCTION Nitrogen (N) deficiency is present in common bean (Phaseolus vulgaris L.) fields in most production regions in Central America and the Caribbean (CA/C), especially on small hillside farms where no or sub-optimum levels of fertilizer are used. Under these conditions, Rhizobium inoculants could represent a cheap and effective input to increase bean yield. Despite the potential benefits from increased biological nitrogen fixation, Rhizobium inoculation is rarely used by farmers in CA/C. Nodulation and nitrogen fixation (N2) of bean cultivars in response to Rhizobium inoculation is quite variable due to several biological and edaphic factors (Graham et al. 2003). …

Using The Vehicle Routing Problem To Reduce Field Completion Times With Multiple Machines, Hasan Seyyedhasani, Joseph S. Dvorak

Biosystems and Agricultural Engineering Faculty Publications

The Vehicle Routing Problem (VRP) is a powerful tool used to express many logistics problems, yet unlike other vehicle routing challenges, agricultural field work consists of machine paths that completely cover a field. In this work, the allocation and ordering of field paths among a number of available machines has been transformed into a VRP that enables optimization of completion time for the entire field. A basic heuristic algorithm (a modified form of the common Clarke-Wright algorithm) and a meta-heuristic algorithm, Tabu Search, were employed for optimization. Both techniques were evaluated through computer simulations in two fields: a hypothetical basic …
