Potassium Fertilizer Rate Recommendations: Does Accounting For Soil Stock Of Potassium Matter?, Kimberly B. Oliver, Michael P. Popp, Di Fang, John D. Anderson, Nathan A. Slaton, Gerson L. Drescher, Trenton L. Roberts, Jada Thompson

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Profitability, yield, and fertilizer use are compared across three different potassium (K) fertilizer rate recommendation ideologies. Existing agronomic, “build and maintain” rate recommendations (KE) are compared to profit-maximizing rates with and without taking long-run soil-test K (STK) implications into account. Regardless of starting STK, K use equilibrated over the course of 3 years irrespective of ideology. Since taking long-run STK into account did not alter ending STK and only led to a miniscule yield effect, we encourage producers to use annual profit-maximizing K rates that were 3–11% lower than KE rates and generated more profit with minimal yield loss.

Quantifying Wheat Blast Disease Induced Yield And Production Losses Of Wheat: A Quasi-Natural Experiment, Khondoker Abdul Mottaleb, David P. Hodson, Timothy J. Krupnik, Kai Sonder

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Applying the difference-in-difference (DID) estimation procedure, this study quantifies the wheat blast (Magnaporthe oryzae pathotype Triticum) induced losses in wheat yield, quantity of wheat sold, consumed, or stored, as well as wheat grain value in Bangladesh in 2016 following a disease outbreak that affected over 15,000 ha. Estimates show that the blast-induced yield loss was 540 kg ha⁻¹ on average for households in blast-affected districts. Estimated total wheat production loss was approximately 8,205 tons worth USD 2.1 million in during the 2016 outbreak. Based on these insights, we discuss the need for long-term assured investment and concerted research …

Projecting Wheat Demand In China And India For 2030 And 2050: Implications For Food Security, Khondoker Abdul Mottaleb, Gideon Kruseman, Aymen Frija, Kai Sonder, Santiago Lopez-Ridaura

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Introduction: The combined populations of China and India were 2.78 billion in 2020, representing 36% of the world population (7.75 billion). Wheat is the second most important staple grain in both China and India. In 2019, the aggregate wheat consumption in China was 96.4 million ton and in India it was 82.5 million ton, together it was more than 35% of the world's wheat that year. In China, in 2050, the projected population will be 1294–1515 million, and in India, it is projected to be 14.89–1793 million, under the low and high-fertility rate assumptions. A question arises as to, what …

The Relation Between Wheat, Soybean, And Hemp Acreage: A Bayesian Time Series Analysis, Joohun Han, John N. Ng'ombe

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

The 2018 United States Farm Bill has opened the possibility for farmers to increase their profits through hemp cultivation. The literature suggests hemp has the potential to replace soybeans in soybean–wheat double-cropping because hemp shares key attributes of soybeans as a rotation crop (profitability, potential as an energy crop, and maintenance of soil fertility). Nonetheless, due to a short history of hemp cultivation in the USA, it is difficult to predict a time series relationship between hemp, soybean, and wheat through conventional approaches. In this article, we use Bayesian time series models and data from Statistics Canada and the Alberta …

How Do Usda Announcements Affect International Commodity Prices?, Andrew M. Mckenzie, Yangmin Ke

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Our event study results show that Chinese soybean futures and to a lesser extent Chinese corn futures react to the release of World Agricultural Supply and Demand Estimate reports. Second, using a copula based Conditional Value at Risk (CoVaR) approach we find strong evidence that risk spillovers from U.S. to Chinese futures markets are much larger on report release days than on pre and post-release days. In addition, our results indicate that risk spillovers from U.S. to Chinese futures markets, irrespective of trading day, are asymmetric in nature, with upside risk spillovers much higher than downside risk spillovers.

The Future Of Crispr Gene Editing According To Plant Scientists, Job De Lange, Lawton Lanier Nalley, Wei Yang, Aaron Shew, Hans De Steur

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

This study surveyed 669 plant scientists globally to elicit how (which outcomes of gene editing), where (which continent) and what (which crops) are most likely to benefit from CRISPR research and if there is a consensus about specific barriers to commercial adoption in agriculture. Further, we disaggregated public and private plant scientists to see if there was heterogeneity in their views of the future of CRISPR research. Our findings suggest that maize and soybeans are anticipated to benefit the most from CRISPR technology with fungus and virus resistance the most common vehicle for its implementation. Across the board, plant scientists …

School Breakfast And Student Behavior, Andres Cuadros-Menaca, Michael R. Thomsen, Rodolfo M. Nayga Jr.

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

The School Breakfast Program (SBP) is one of the largest nutrition assistance programs serving school-aged children in the US. It provides reimbursement to states for the operation of breakfast programs in schools. Student participation in the SBP is, however, much lower than the National School Lunch Program (NSLP). Because missing breakfast could result in hunger that could then influence children's interpersonal relations and classroom behavior (i.e., disciplinary infractions), some schools have implemented breakfast after the bell (BAB), which encompasses alternative breakfast delivery methods that make breakfast available to children after the school day commences. We use a difference-in-differences design with …

Structural Shifts In Food Basket Composition Of Rural And Urban Philippines: Implications For The Food Supply System, Subir Bairagi, Yacob Zereyesus, Sampriti Baruah, Samarendu Mohanty

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Empirical evidence on the responsiveness and sensitivities of food consumption to its drivers is vital for conducting economic studies. Despite recent attempts to provide such estimates, much empirical work remains to be done considering the prevailing shifts in consumption trends in the Philippines. Price and expenditure elasticities are estimated for seven food categories for rural and urban Filipino households, using Stone–Lewbel (SL) price indices and the quadratic almost-ideal demand system (QUAIDS) model. We used multiple years (2006, 2009, 2012, 2015, and 2018) of the Philippines Family Income and Expenditure Survey (FIES) to estimate the food demand system. The results show …

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

The supply chain disruptions caused by the COVID-19 outbreak have led to changes in food prices globally. The impact of COVID-19 on the price of essential and perishable food items in developing and emerging economies has been lacking. Using a recent phone survey by the World Bank, this study examines the impact of the COVID-19 pandemic on the prices of the three essential food items in India. The results indicate that price of basic food items such as atta (wheat flour) and rice increased significantly during the pandemic compared to the pre-pandemic period. In contrast, during the same period, the …

Characterizing Implied Volatility Functions From Agricultural Options Markets, Andrew M. Mckenzie, Michael R. Thomsen, Michael K. Adjemian

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

We provide the first comprehensive characterization and comparison of implied volatility functions for five major agricultural options markets—corn, soybeans, soft red winter wheat, live cattle, and feeder cattle—using intraday tick data. Our results show that cattle markets exhibit a distinct leftward skew, which is puzzling and indicates that out-of-the-money traded put options are theoretically overpriced. In contrast, we find that grain market implied volatility functions display a flatter, less pronounced smile pattern. We examine market sentiment induced short-term hedging pressures using Commodity Futures Trading Commission reports, and market uncertainty around Cattle on Feed reports, as potential causes of the cattle …

Rice Quality And Its Impacts On Food Security And Sustainability In Bangladesh, Indrani Saha, Alvaro Durand-Morat, Lawton Lanier Nalley, Mohammad Jahangir Alam, Rodolfo M. Nayga Jr.

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Rice market efficiency is important for food security in countries where rice is a staple. We assess the impact of rice quality on rice prices, food security, and environmental sustainability in Bangladesh. We find that while price varies as expected for most quality attributes, it is unaffected by a broken percentage below 24.9 percent. This reveals a potential inefficiency, considering the average 5 percent broken rate observed in the market. An increase in the broken rate of milled rice within the limits supported by our findings can, ceteris paribus, increase rice rations by 4.66 million a year, or conversely, …

Peer Irrigators And The Choice Of Field Management And Water Control Practices For Irrigation In Arkansas, Victoria Bailey, Kent Kovacs, Christopher Henry, Qiuqiong Huang, Larry J. Krutz

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

We examined how irrigation techniques in use by family and friends influence the use and share of land utilizing different irrigation techniques by Arkansas producers. A bivariate sample selection model simultaneously estimated how farm characteristics determine the use and explain the share of a farm that utilizes an irrigation technique. We found that the irrigation techniques in use by family and friends do affect the irrigation techniques a producer uses and the share of acres utilizing different irrigation techniques. A producer with a family or friend that uses end-blocking irrigation is 41% more likely to use end-blocking themselves. Having a …

Economic And Ghg Emissions Changes Of Aeration And Gypsum Application, Michael Popp, Karen Renee Lindsay, Amanda Ashworth, Philip Moore, Phillip R. Owens, Taylor Adams, Melissa Mccarver, Becky Roark, Dan Pote, John Pennington

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

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 …

Simulating The Feasibility Of Dual Use Switchgrass On Cow-Calf Operations, Michael P. Popp, Amanda J. Ashworth, Charles P. West

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Meeting biorefineries' demands for lignocellulosic biomass will require sourcing feedstock without affecting the food or animal-feed supply. A decision-aid model can assess the dual use of switchgrass (Panicum virgatum L.) to maintain animal production while providing biomass. We simulated a mixed-farm operation with 156 ha of hay+pasture, 96 beef cows (Bos spp.), and poultry (Gallus gallus L.) production wherein the hay land was converted to switchgrass for dual use as biomass and forage. The cow-calf simulator tracked changes in forage and cattle production, economic returns, and net greenhouse gas (GHG) emissions. Dual use of switchgrass consisted of …

On The Use Of Virtual Reality In Mitigating Hypothetical Bias In Choice Experiments, Di Fang, Rodolfo M. Nayga Jr., Grant H. West, Claudia Bazzani, Wei Yang, Benjamin C. Lok, Charles E. Levy, Heather A. Snell

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

Choice experiments have been extensively used in many stated preference studies and disciplines. In order to give external validity to stated preferences, participants must behave the same in an experiment setting as they do in reality. The difference between a decision made in a real experiment and a hypothetical experiment is commonly attributed to "hypothetical bias." In this paper, we investigate whether virtual reality can reduce hypothetical bias in choice experiments. We conducted a set of experiments using the Food and Drug Administration's new Nutrition Facts Label for yogurts. Participants were randomly assigned to non-hypothetical and hypothetical experiments, which differed …

Preserving Cultural Heritage Through The Valorization Of Cordillera Heirloom Rice In The Philippines, Subir Bairagi, Marie Claire Custodio, Alvaro Durand-Morat, Matty Demont

Agricultural Economics and Agribusiness Faculty Publications and Presentations

---

For centuries, heirloom rice varieties have been grown on the terraces of the Cordillera Mountains of Luzon, Philippines, terroirs known for their significant historical, cultural, and aesthetic values. However, heritage heirloom rice farming is gradually being abandoned, mainly because of its lower productivity and the struggle of the sector to create a sustainable niche market for heirloom rice by branding its cultural, social, and nutritional values. We propose several demand-side intervention strategies for the valorization of heirloom rice. To support the development of a segmented marketing strategy for heritage farming, we provide evidence on urban consumers’ willingness to purchase heirloom …
