2021 Cantaloupe Variety Evaluation In Indiana, Wenjing Guan, Dan Egel, Dennis Nowaskie, Dean Haseman Nov 2021

2021 Cantaloupe Variety Evaluation In Indiana, Wenjing Guan, Dan Egel, Dennis Nowaskie, Dean Haseman

Midwest Vegetable Trial Reports

Indiana ranks sixth in cantaloupe production in the US. A total of 1,800 acres of cantaloupes were planted in Indiana with a production value of $8.6 million in 2018 (USDA 2021). Melon produced in Indiana is primarily eastern-type cantaloupes. Traditional eastern-type cantaloupes have less pronounced netting, larger fruit size, softer flesh and shorter shelf life compared with western-type cantaloupes. They are harvested at quarter-slip to full-slip stage, and require frequent harvest. Recently, extended shelf life varieties have been developed and are becoming attractive in the eastern market. This variety trial included 11 traditional eastern-type cantaloupes, as well as extended shelf-life …

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 …

Research Note: Evaluation Of Quinine As A Chemoprophylactic Candidate Against Histomoniasis In Turkeys, L. C. Beer, B. M. Hargis, C. N. Vuong Nov 2021

Research Note: Evaluation Of Quinine As A Chemoprophylactic Candidate Against Histomoniasis In Turkeys, L. C. Beer, B. M. Hargis, C. N. Vuong

Poultry Science Faculty Publications and Presentations

Histomoniasis, also commonly referred to as blackhead disease, is caused by the protozoan parasite Histomonas meleagridis. Since the removal of nitarsone in 2015, no approved prophylactics are available for mitigating histomoniasis. Disease incidence and high mortalities are frequently associated with turkey flocks, although infection of broiler breeders also occurs. Quinine is a naturally occurring alkaloid with antimalarial properties. In vitro assays have shown strong antihistomonal properties of quinine, leading to our hypothesis that quinine inclusion within the feed could prevent histomoniasis in turkeys. Selected concentrations of quinine were included within a turkey starter diet to evaluate effects on body …

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 Oct 2021

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 …
