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 …

Determining The Accuracy Of Holstein Bull Semen Prices With A Two-Tier Efficiency Model, Loren W. Tauer
Determining The Accuracy Of Holstein Bull Semen Prices With A Two-Tier Efficiency Model, Loren W. Tauer
Journal of Applied Farm Economics
The pricing accuracy of dairy bull semen available for artificial insemination is investigated using a price model cast in terms of a two-tier efficiency model, which allows estimating an overprice and underprice given the net return the bull’s daughter is expected to contribute to the farm based upon the transmittable trait characteristics of a bull. The estimation produces statistically significant coefficients, including the coefficients for the overpricing and underpricing of the semen. The average estimate of overpricing is around 25%, and the average estimate of underpricing is around 33%. As expected, low semen prices tend to be underpriced and high …

Does The Covid-19 Pandemic Change Consumers’ Food Consumption And Willingness-To-Pay? The Case Of China, Wei Yue, Na Liu, Qiujie Zheng, H Holly Wang
Department of Agricultural Economics Faculty Publications
Since COVID-19 was first detected in China in 2019, governments around the world have imposed strict measures to curb the spread of the coronavirus, which substantially impacted people’s life. Consumers’ food consumption behavior has also changed accordingly with reduced grocery shopping frequency, replaced in-person grocery shopping with online shopping, and increased valuation on food. In this paper, we aim to investigate the change in Chinese consumers’ food consumption and their willingness to pay (WTP) for vegetables and meat, using a dataset with 1206 online samples collected between February and March 2020. Consumers’ WTP for vegetables and meat is estimated using …

Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young
Hemp Production Network Effects: Are Producers Tipped Toward Suboptimal Varietal Selection By Their Neighbors?, Tanner Mccarty, Jeffrey Young
Journal of Applied Farm Economics
The 2018 farm bill removed industrial hemp from the Schedule 1 Controlled Substance List. In response, states scrambled to enact hemp legislation. Some hemp flower producers report their hemp fields were cross- pollinated by a neighbor growing a different hemp cultivar. For hemp flower crops, cross- pollination reduces cannabinoid concentration levels within the flower; these concentration levels dictate flower price. We show that in a repeated game, once a sufficiently large percentage of growers decide to plant hemp fiber/seed crops, cross-pollination forces flower growers to convert to fiber/seed to avoid the negative network externality. Over time, a stable, suboptimal Nash …
Evaluation Of Bell Pepper Cultivars With And Without Resistance To Bacterial Leaf Spot And Phytophthora, West Central Minnesota, Nathan Dalman, Steve Poppe
Evaluation Of Bell Pepper Cultivars With And Without Resistance To Bacterial Leaf Spot And Phytophthora, West Central Minnesota, Nathan Dalman, Steve Poppe
Midwest Vegetable Trial Reports
Bacterial leaf spot (BLS) and Phytophthora (PHY) diseases are a common problem for Minnesota bell pepper producers and if not detected and treated early enough, these diseases can kill the plants. There are cultivars that have resistance to these particular diseases but these cultivars must maintain yields similar to traditional cultivars in order to be desired by producers and buyers. Our goal was to determine any differences in performance between cultivars with and without resistance. Yield, fruit size and number of fruit per plant were the evaluated characteristics.

Midwest Vegetable Trial Reports
Latinx fresh market vegetable farmers in Minnesota face numerous barriers to market access. Many Latinx farmers live in rural communities where farmers market sales are low, and opportunities for wholesale are limited. The growers who make up Shared Ground Farmers’ Cooperative have developed an innovative cooperative marketing system to aggregate produce and sell it in Twin Cities markets, but many of the individual farmers involved also wish to find ways to keep the produce they grow in their own communities. This project emerged through a series of discussions about finding niche markets for culturally relevant crops in small-town Mexican restaurants …

Effects Of Using Low Tunnel And Grafted Plants For Watermelon Production Under Low Temperature Stress In Indiana, Wenjing Guan
Effects Of Using Low Tunnel And Grafted Plants For Watermelon Production Under Low Temperature Stress In Indiana, Wenjing Guan
Midwest Vegetable Trial Reports
This study evaluated the effect of using low tunnel and grafted plants for early-season watermelon production in Indiana. Results of the study indicated that grafted seedless watermelon plants can better tolerate cold stress in the early watermelon season compared to non-grafted seedless watermelon plants. Grafted plants with ‘Camelforce’ rootstock had better old tolerance than that of ‘Carolina Strong Back’ rootstock. The effect of using low tunnels to improve plant survival rate under extreme weather conditions is limited, which depend on temperate stress and cold tolerance of the plants.

Indiana STEM Education Conference
As the food industry has evolved over the years, consumers have more accessible and convenient outlets to buy groceries, dine in, or carry out. While there are many advantages to this ever-changing industry, a large gap exists in the understanding of food production from farm to fork. Consumer perceptions are influenced beginning at an early age. Education is the solution to bridge this gap between farm to fork; however, there are limited STEM-based agricultural resources available for teachers to implement in their classrooms. Creating these agricultural resources provides teachers the opportunity to share the story of the agricultural industry with …
