Nitrogen fertilizer recommendations in corn (Zea mays L.) that match the economically optimal nitrogen fertilizer rate (EONR) are imperative for profitability and minimizing environmental degradation. However, the amount of soil N available for the crop depends on soil and weather factors, making it difficult to know the EONR from year-to-year and from field-to-field. Our objective was to explore, within the framework of hydrologic soil groups and drainage classifications (HGDC), which site-specific soil and weather properties best estimated corn N needs (i.e., EONR) for two application timings (at-planting and side-dress). Included in this investigation was a validation step using an independent …

The Effects Of Omega-3 Pufa Infusions During Late Gestation On Developmental Pathologies In The Intrauterine Growth Restricted Fetus, Taylor A. Lacey

Department of Animal Science: Dissertations, Theses, and Student Research

Low birthweight due to intrauterine growth restriction is associated with metabolic disorders after birth. Our 1st study assessed deficits in skeletal muscle glucose metabolism and pancreatic β cell function in IUGR fetal sheep. We aimed to evaluate the effectiveness of daily intravenous infusions of the anti-inflammatory ω-3 polyunsaturated fatty acid (PUFA), eicosapentaenoic acid (EPA), as a means of improving deficits previously observed in the IUGR fetus by targeting fetal systemic inflammation. The presence of systemic inflammation in IUGR fetuses was evident by increased total circulating populations of total leukocytes, lymphocytes, and monocytes. However, these were …

The Effect Of Natural Elicitors And Cold Storage Period On Quality Improvement Of Uae Date Palm Fruits (Phoenix Dactylifera, Cv. Barhi), Fatima Yaaqoub Yousef Al Shaibani

Theses

Date palm is an agricultural crop of economic importance in most Arab countries. Among the different varieties of date palms grown in the United Arab Emirates, the Barhi variety is extremely popular and is often consumed at the bisr stage (first edible stage). However, the major challenge for this fruit at bisr stage is to maintain its quality over a long period after harvest and during marketing. The objective of this study was to evaluate the synergistic effect of preharvest spraying with a natural elicitor, namely chitosan (Ch) 1%, alone and in combination with salicylic acid (SA) 2 mM and …

Alternative pasture management strategies are needed to ensure long-term ecological and economical use of abundantly available poultry litter as a source of valuable nitrogen (N), phosphorus (P) and potassium (K). In combination with the common practice of broadcasting poultry litter and soil compaction from equipment and livestock traffic, pasture aeration offers the potential for added soil water penetration and reduced nutrient runoff by creating soil perforations ranging length from 5 to 15 cm using metal spikes that penetrate the soil to 15 cm depth. Also, the addition of gypsum can further reduce P runoff. We evaluate different pasture management scenarios …


Investigating Plant Tolerance For The Management Of Insect Pests In Rice, James Michael Villegas 2021 Louisiana State University and Agricultural and Mechanical College

Investigating Plant Tolerance For The Management Of Insect Pests In Rice, James Michael Villegas

LSU Doctoral Dissertations

The rice water weevil, Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), is the most destructive and widespread insect pest of rice (Oryza sativa L., Poaceae) in the USA. This insect poses a global threat to rice production, having invaded rice-producing regions of Asia and Europe. Moreover, lepidopteran stemborers, particularly the invasive Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae), are increasingly becoming problematic in Louisiana rice. Although insecticidal seed treatments have been widely used against weevils and stemborers, alternative management strategies are needed. Plants possess defense-related traits that both reduce injury from herbivores (resistance) and the amount of yield loss per …
