Are Returns From Commercial Farming Heterogeneous? Case Of Wheat Growers In North India, Saroj Verma, Kirtti Ranjan Paltasingh, Phanindra Goyari

Journal of Applied Farm Economics

Contract farming (CF), generally a commercial farming system, is widely perceived as a welfare enhancement strategy in rural areas where agriculture is the major source of livelihood. However, those welfare implications have not been adequately explored in Indian agriculture. So, this study examines the returns to CF and the heterogeneity in their returns across various groups of wheat growers in Haryana, a leading agrarian state in India. Using an endogenous switching regression model on cross-sectional data of 754 farm households, the study found that CF adopters would lose 27% of their gross margins and 11% of their crop output if …

Long-Term Changes In Relative Humidity And Soil Wetness: Implications On Agriculture And Environmental Sustainability In Western Himalaya, Ashwani Ashwani, Pankaj Kumar

Journal of Environmental Science and Sustainable Development

Long-term climate changes in humidity and soil wetness in the cold deserts of the Western Himalaya are still not well researched. Understanding the long-term trends of relative humidity (RH) and soil moisture is crucial in high-altitude, cold desert regions for effective agricultural management and environmental sustainability. The study was conducted in a part of the western Himalaya, which is an ecologically fragile zone with a highly sensitive agricultural region that is vulnerable to climatic variations. A comprehensive study was conducted to evaluate the spatiotemporal variability of RH and soil wetness by means four techniques: Mann-Kendall, Modified Mann-Kendall, Sen’s slope estimator, …

Mulching And Time Of Planting Impact On Southern Blight Disease And Industrial Hemp Production, Sai Suvidh Maddela, Emmanuel C. Omondi, Margaret T. Mmbaga, Anand Kumar, Mitchell Dale Richmond, Philip O. Hinson, Bharat Pokharel

Agricultural and Environmental Sciences Faculty Research

Southern blight, a disease caused by the soil-borne fungus Sclerotium rolfsii (S. rolfsii), is favored by the hot and humid conditions of the southeastern United States, posing a significant challenge to hemp production in Tennessee. Black plastic mulch (BPM), commonly used for weed control, can exacerbate the disease. There is limited information on the effects of straw mulch (SM), known to moderate soil temperatures and moisture, or planting time in disease management. Field studies were conducted in 2022 and 2023 at Tennessee State University to evaluate the effects of planting time, mulch type, and biofungicide application on disease severity, weed …

Optimal Drought Management Actions For Cattle Operations On The Uintah And Ouray Indian Reservation, Kynda R. Curtis, Tatiana Drugova, Man-Keun Kim

All Current Publications

In this fact sheet, we examine the drought management options available to cattle operations on the Uintah and Ouray Reservation, the largest Native American reservation in Utah. Specifically, we discuss the results of a study that evaluated the economic outcomes of two common drought response strategies: herd reduction and supplemental hay purchases. We also provide recommendations for ranchers on optimal strategies, i.e., those that maximize profits for two rancher types, differentiated by their willingness to accept risk (risk-neutral) or avoid it (risk-averse).

Biostimulant Applications In Watermelon Production, Evan A. Christensen, Milena Oliveira, Youping Sun, Grant Cardon, Dan Drost

All Current Publications

Watermelon is a water-intensive vegetable crop that is sensitive to drought and requires adequate nutrient supply for good yield and fruit quality. It is an important vegetable crop grown on 142,000 acres in the United States and 586 acres throughout Utah. Utah experienced its driest year on record in 2020 during a five-year drought (2019 to 2023). This affected local ecosystems, including the Great Salt Lake, which experienced record-low water levels. The drought also negatively affected the agricultural sector, including watermelon growers. Higher-than-average fertilizer prices in recent years have also threatened watermelon production. Growing awareness of agriculture's water use and …

Why Agtech Startups Fail? Evidence From Global Shutdown Patterns In 2025 And The Cost-Adoption Mismatch Effect, Ankit Chandra, Ishani Lal

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Agricultural technologies are widely seen as a driver for sustainability, resilience, and food-system transformation. Yet in 2025, agtech startup across North America, Europe, Asia, and Africa experienced multiple shutdowns. Although each company closed for its own reasons, the failures highlight consistent underlying patterns. We analyze 18 publicly reported shutdowns across controlled-environment agriculture (CEA), robotics, insect protein, digital platforms, sensors, and ag-biotechnology. We find that most ventures struggled not with scientific feasibility but with economic and adoption dynamics at the farm level. We identify a Cost-Adoption Mismatch Effect, in which the capital and operational burden of a technology exceeds farmers’ capacity …

Evaluation Of Eight Parthenocarpic Slicing Cucumber Cultivars And Four Production Systems In Southwest Michigan In 2025, Ben Phillips

Midwest Vegetable Trial Reports

In the machine-harvested pickling cucumber system, parthenocarpic (parth) varieties make up about 50% of the market, and is growing. The seed cost is higher, but this is offset by not needing to contract or truck bees and an increased yield when planted at half the population of standard varieties. Additionally, they hold their shape and size better when moisture and temperatures fluctuate, reducing docked payments from graders. In pickling cucumbers, a breakeven yield is approximately 250 bushels per acre with a plant population of 30,000 plants per acre. Plant populations can play a strong role in economic viability, as demonstrated …

High Spatiotemporal Resolution Monitoring Of Crop Water Stress Across The Contiguous United States Using Harmonized Landsat And Sentinel-2 Data, Na Chen, Yanlei Feng, Na Wang, Jevan Yu, Mohammad Reza Alizadeh, Yifeng Cui, Ning Ye, Wenzhe Jiao, Joshua B. Fisher, César Terrer

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Accurate and timely monitoring of crop water stress is essential for efficient agricultural water management, ultimately maintaining and improving crop productivity. While Landsat has been used for this purpose, its temporal resolution hampers timely detection of crop water stress. The recently released Harmonized Landsat and Sentinel-2 Version 2.0 dataset, which enables a higher-frequency time series of satellite observations (2–3 days, 30 m), offers a promising solution to this challenge. However, its potential for crop stress monitoring remained unexplored. In this study, we utilized 923 HLS satellite tiles to assess crop water stress across the contiguous United States (CONUS).

Consumer Perceptions Of Farmers Market Performance: A Comparative Analysis Across States And Age Groups, Azita Varziri, Timothy A. Woods, Shuoli Zhao

Agricultural Economics Faculty Publications

The USDA Agricultural Marketing Service has invested in direct-to-consumer initiatives to expand local food consumption and enhance farmers market opportunities. To evaluate the effectiveness of these efforts, this study employs a sample-selected ordered probit model to analyze consumer perceptions of farmers market performance across four states in the Southeast United States. Specifically, we examine differences in awareness and performance of product quality, diversity, and market infrastructure. Awareness and perceptions vary significantly by age, other demographics, and state. These insights provide market organizers and policymakers with data-driven strategies to tailor marketing efforts and improve engagement across diverse consumer segments.
