What Do Ongoing High Interest Rates Mean For Ag Producers?, Jay Parsons, John Hewlett, Jeff Trandel
Center for Agricultural Profitability
As we progress through 2024, the agricultural sector faces significant economic pressures from persistently high borrowing costs.
In the crop sector, smaller cash buffers and the need to preserve working capital due to tightening profit margins resulting from lower crop prices and higher input costs contributed to an increase in farm operating loan activity in the first quarter of 2024 (Kansas City Federal Reserve). Farm machinery and equipment costs also rose considerably in the last few years. As a result, loans to purchase such equipment are larger and the higher interest rates only complicate the purchase decisions even further. Farmers …

Violent Conflict Drives World Hunger And Food Insecurity, E. Wesley F. Peterson
Violent Conflict Drives World Hunger And Food Insecurity, E. Wesley F. Peterson
Cornhusker Economics
The World Food Program (WFP) with support from the United States and other countries works to provide food to those in need as a result of conflict, adverse climate effects, poverty, and government mismanagement. It is limited in what it can do, however, by budget constraints and rising food prices. On top of the financial issues, the delivery of food assistance is particularly complicated in areas of conflict where warring adversaries often hijack food supplies intended for the other side. While it is illegal under International Humanitarian Law to use starvation as a weapon of war, Dzerowicz (2023) has identified …

Adopting Yield-Improving Practices To Meet Maize Demand In Sub-Saharan Africa Without Cropland Expansion, Fernando Aramburu-Merlos, Fatima A. M. Tenorio, Nester Mashingaidze, Alex Sananka, Stephen Aston, Jonathan J. Ojeda, Patricio Grassini
Department of Agronomy and Horticulture: Faculty Publications
Maize demand in Sub-Saharan Africa is expected to increase 2.3 times during the next 30 years driven by demographic and dietary changes. Over the past two decades, the area croppedwithmaize has expanded by 17million hectares in the region, with limited yield increase. Following this trend could potentially result in further maize cropland expansion and the need for imports to satisfy domestic demand. Here, we use data collected from 14,773 smallholder fields in the region to identify agronomic practices that can improve farm yield gains. We find that agronomic practices related to cultivar selection, and nutrient, pest, and crop management can …

This study aimed to evaluate the changes in activity of group-housed, newly weaned pigs challenged with lipopolysaccharide (LPS). At weaning, pigs (n = 192, 5.73 ± 1.8 kg) were stratified by sex, litter, and body weight (BW) and randomly assigned to one of three treatments (16 pigs/pen, 4 pens/treatment): 1) Saline-injected (SAL), 2) 50% challenged [50%-LPS) – only half of the pigs in a pen (8 pigs) were challenged with LPS and 3) 100% challenged (100%-LPS) – all pigs in a pen were challenged with LPS. Pigs in the SAL and 32 in the 50%-LPS treatment received a 3.0 …
Adding Parasite Resistance To A Hair Sheep Breeding Objective, Bob Forbes
Adding Parasite Resistance To A Hair Sheep Breeding Objective, Bob Forbes
Department of Animal Science: Dissertations, Theses, and Student Research
The U.S. Hair Sheep Index was designed to increase total weight of lamb weaned per ewe lambing (TW) using estimated breeding values (EBV) for direct (DWWT) and maternal (MWWT) weaning weight, and number of lambs born (NLB) and weaned (NLW), as selection criteria. Producers are interested in adding post-weaning fecal egg count EBV (PFEC), an indicator of parasite resistance, to the index to achieve genetic change in both TW and PFEC.
First, the effects of adding PFEC alongside TW to the breeding objective of indexes that used either phenotypes or EBV as selection criteria were studied. Since MWWT is …

Evaluation Of Critical Weed-Free Period For Three Sweetpotato (Ipomoea Batatas) Cultivars, Emmanuel G. Cooper, Stephen L. Meyers, Jeanine Arana, Katherine Jennings, Ashley Adair, Kevin D. Gibson, William G. Johnson
Department of Horticulture & Landscape Architecture Faculty Publications
Sweetpotato [Ipomoea batatas (L.) Lam.] is a staple crop that provides nutritional benefits to humans globally, but it is subject to yield loss when competing with weeds, especially during the early stage of establishment. Yield loss can vary widely based on the cultivar, production environment, weed species, and management techniques. To address this challenge, we conducted field research at the Samuel G. Meigs Horticulture Research Farm, Lafayette, IN, and at the Southwest Purdue Agricultural Center, Vincennes, IN, in 2022 to determine the effect of sweetpotato cultivar on the critical weed-free period. The experiment was a split-plot design, with weed-free interval …

Feeding Dried Distillers Grains With Solubles To Lactating Dairy Cattle: Whole Animal Energy Utilization And Manure Biogas Production, Grant Michael Fincham
Feeding Dried Distillers Grains With Solubles To Lactating Dairy Cattle: Whole Animal Energy Utilization And Manure Biogas Production, Grant Michael Fincham
Department of Animal Science: Dissertations, Theses, and Student Research
When DDGS are fed to lactating dairy cattle, the observed response in energy supply, milk production, and methane production varies among studies. One potential reason for these observed discrepancies is the nature of the diet formulation itself. Furthermore, little research has been conducted to examine how dietary changes can affect dairy cattle manure composition and methane production in an anaerobic manure digester. In order to gain a better understanding of these topics, we conducted two experiments. The first experiment was conducted to test how the manipulation of lactating dairy cattle diets affects energy utilization, milk production, methane production, and manure …
Next-Generation Crop Monitoring Technologies: Case Studies About Edge Image Processing For Crop Monitoring And Soil Water Property Modeling Via Above-Ground Sensors, Nipuna Chamara

Establishment Of Wildflower Islands To Enhance Roadside Health, Ecological Value, And Aesthetics, Jackson Ebbers
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Roadsides provide an abundant opportunity to increase connectivity of fragmented landscapes with diminishing floral resources for pollinating insects. The ecological value of these sites is often overlooked as quality habitat for pollinators, particularly monarch butterflies, which have been experiencing severe declines due to loss of habitat and loss of milkweeds that provide food for their larvae. Land managers across the nation are realizing the potential of roadsides to provide high quality floral resources for the benefit of insects and other wildlife. Current wildflower seed mixes used by state transportation departments are often low diversity and may only be implemented following …

Research outputs 2022 to 2026
The popularity of insect protein as a food and feed supplement is growing. Protein quality, end use and prices vary considerably between different insect species, which may incentivise insect protein adulteration. Here, near-infrared (NIR) spectroscopy and chemometrics were used to detect the presence of cricket, black soldier fly larvae (BSFL) and mealworm proteins in a simulated complex insect protein mixture. Additionally, BSFL protein powders collected from three commercial sources were investigated to determine whether the NIR-based technology can discriminate the proteins obtained from different companies based on their composition. The proximate analysis suggests compositional protein, fat and chitin differences between …

Agricultural Groundcover Update March 2024, Justin Laycock
Natural resources published reports
- In March, over 10% (1,577,000 ha) of the arable farmland in the south-west of Western Australia had less than 50% vegetative groundcover, which is inadequate to prevent wind erosion.
- The northern grainbelt had the highest risk of wind erosion and over 20% of this farmland had inadequate groundcover.
- About 1.3% (191,000 ha) of arable land had a high to very high risk of wind erosion because groundcover was less than 30%.
Assessing The Influence Of Interseeded Cover Crops On Beneficial Arthropod Abundance In A Northeastern Agroecosystem, Charles Cooper
Assessing The Influence Of Interseeded Cover Crops On Beneficial Arthropod Abundance In A Northeastern Agroecosystem, Charles Cooper
Honors College
Conservation agriculture approaches are gaining traction as the planet’s food system grapples with climate change, oil depletion, and rampant environmental degradation (Palm et al., 2014). Cover cropping is an integral practice of conservation agriculture. Ground dwelling arthropods play an important role in agroecosystems, providing ecosystem services including seed predation and nutrient cycling. Because the relationship between cover crops and arthropod abundance are likely influenced by management conditions, I investigated arthropod abundance in a field interseeded with cover crops on a research farm in Maine, United States. Interseeding is an emerging practice in the northeastern United States, with potential to address …
