Rebuilt And Remade: The Florida Citrus Industry, 1909-1939, James Padgett 2018 University of Central Florida

Rebuilt And Remade: The Florida Citrus Industry, 1909-1939, James Padgett

Electronic Theses and Dissertations

Prior to orange juice concentrate, Florida citrus was already an industrialized agricultural sector. This thesis explores the early-20th-century Florida citrus industry and demonstrates that contemporary farming practices were influential in advancing how citrus was produced, processed, worked, marketed, and regulated in early-20th-century Florida. Restarted after devastating freezes in 1894-1895, resolute Florida growers rebuilt their groves into marvels of large-scale citrus fruit production. Continuing a legacy in experimental crossbreeding, improved varieties of citrus were developed to lengthen the season and markets. Advocated by nurserymen and university educators, biological innovation helped the citrus thrive in the 1910s and 1920s from adverse weather …


Production Of Industrial Hemp In Kentucky, Patrick J. Hooks 2018 Murray State University

Production Of Industrial Hemp In Kentucky, Patrick J. Hooks

Murray State Theses and Dissertations

Hemp, or Cannabis sativa, is a plant that can be used for many products, such as textiles, oils, and seeds. Currently, the four most important textiles in the United States’ manufacturing industry are cotton, wood, silk, and linen. In the 1950s, the United States Government banned the production of hemp, as it was legislated into the marijuana policy of this industry. Because of this, the hemp crop was pushed out of the textile industry and replaced by cloth, linens, and textiles. Section 7606 of the Agriculture Act of 2014 declares the State Department of Agriculture’s legalization of industrial hemp …

Tripartite Interactions Of Legumes With Arbuscular Mycorrhizal Fungi And Rhizobial Bacteria: Insight Into Plant Growth, Seed Yield, And Resource Exchange, Arjun Kafle

Electronic Theses and Dissertations

Under natural conditions, legumes, such as alfalfa (Medicago) and soybean (Glycine max) are colonized with arbuscular mycorrhizal (AM) fungi and rhizobial bacteria forming tripartite interactions. Legumes are important crop species due to their high nutritional and economic values. Most of the previous literatures focused on experiments with an individual symbiont: either AM fungi or rhizobial bacteria, but not with both symbionts at the same time, thus our current understanding of resource exchange in tripartite interactions is limited. It has been reported that AM fungi primarily provide phosphate (P), nitrogen (N), and other nutritional and non-nutritional benefits while rhizobial bacteria solely …

Can Solvent-Or Mechanically-Extracted Carinata Meal Be Used As An Effective Source Of Supplemental Protein To Cows Fed Poor Quality Forages?, Emily Jacklyn Rosenthal

Electronic Theses and Dissertations

Brassica carinata is an oilseed crop that requires a relatively short growing season and produces high crop yields. It is a great source for aviation biofuel, however it produces a large amount of waste that may be used as a protein supplement for cattle. We tested the effects of solvent- or mechanically-extracted carinata meal as a protein supplement to ad libitum ground or long-stem corn residue (i.e., corn plant left over from grain harvest) had on cow performance and digestibility. Fifty-six non-pregnant cows in 8 pens had ad libitum access to either long-stem or ground corn residue in addition to …


Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez 2018 South Dakota State University

Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez

Electronic Theses and Dissertations

Phytochemicals such as tannins included in dairy cow nutritional programs, as a natural feed additive, promise to improve rumen bypass protein and consequently reduce the feeding cost by decreasing the amount of CP needed in the ration. Additionally, if tannins are fed along with high quality protein sources, this could improve the AA profile reaching the small intestine and potentially improving health and performance of dairy cows. The black pepper, specifically its alkaloid piperine, is a nontoxic, natural dietary compound with a broad range of physiological activity. Lactating dairy cows ingesting these phytochemicals (tannin extracts and black pepper) will potentially …


Efficiency Of Utilizing Standardized Ileal Digestible Lys And Thr For Whole Body Protein Retention In Pregnant Gilts During Early, Mid And Late Gestation, Ron Aldwin Sapin Navales 2018 South Dakota State University

Efficiency Of Utilizing Standardized Ileal Digestible Lys And Thr For Whole Body Protein Retention In Pregnant Gilts During Early, Mid And Late Gestation, Ron Aldwin Sapin Navales

Electronic Theses and Dissertations

In pregnant pigs, amino acid (AA) requirements represent the sum of those required for maintenance functions, protein retention and efficiency of utilizing AA intake for the aforementioned body processes. The NRC (2012) model assumed AA efficiency is constant across period of gestation; however this is not reflective of the changes in metabolic demand during gestation. Therefore, two experiments were conducted to evaluate the efficiency of utilizing SID Lys and Thr for whole body protein retention (kSIDLys and kSIDThr) in pregnant gilts during early, mid and late gestation. Three 12 d N-balance studies were conducted to represent different periods of gestation. …

Research and Education Center at Princeton Faculty Publications

Grain compaction occurs during bin storage, and its determination is important for the grain mass estimation needed for inventory and auditing. The degree of compaction is dependent on grain type, bin type, moisture content, amount of grain, initial grain bulk density, coefficients of friction, lateral-to-vertical pressure coefficient, and variation in kernel size. Previous studies have correlated several of these parameters, such as bulk density and grain packing, with moisture content. This study investigated the influence of wheat kernel shape and size distribution on packing ratio and compressibility. Two dockage-free hard red winter (HRW) wheat samples, with no shrunken or broken …
