Arkansas Soybean Research Studies 2020, Jeremy Ross
Arkansas Soybean Research Studies 2020, Jeremy Ross
Arkansas Agricultural Experiment Station Research Series
The 2020 Arkansas Soybean Research Studies includes research reports on topics pertaining to soybean across several disciplines from breeding to post-harvest processing. Research reports contained in this publication may represent preliminary or only data from a single year or limited results; therefore, these results should not be used as a basis for long-term recommendations. Several research reports in this publication will appear in other University of Arkansas System Division of Agriculture’s Arkansas Agricultural Experiment Station publications. This duplication is the result of the overlap in research coverage between disciplines and our effort to inform Arkansas soybean producers of the research …

Irrigation Management In High Tunnels, Dan Drost, Brent Black, Melanie Stock
All Current Publications
High tunnels provide season extension for various high-value horticulture crops in a diverse range of climates. These large, plastic-covered structures modify the environmental conditions of the covered area. Temperature management is commonly the focus when growing in high tunnels as this may be the key factor limiting plant growth during much of the year. While high tunnel temperature management is important, growers also need to address water management to ensure plants are not water-stressed. Common mistakes are underestimating water needs, which stresses plants or creates conditions favoring plant diseases and nutrient leaching from overwatering. Knowing when to irrigate and how …
Evaluation Of Soil Moisture Sensing Technologies In Silt Loam And Loamy Sand Soils: Assessment Of Performance, Temperature Sensitivity, And Site- And Sensor-Specific Calibration Functions, K. Sharma, Sibel Irmak, M. S. Kukal, M. C. Vuran, Amit J. Jhala, Xia Qiao

Department of Agronomy and Horticulture: Faculty Publications
Reliable soil moisture information is vital for optimal irrigation management, farm-level agronomic decision-making, hydrologic studies, and cropping systems modeling. A wide range of soil moisture sensing technologies is commercially available, but their performance must be evaluated for diverse conditions of use. In this research, we investigated nine soil moisture sensors based on time-domain reflectometry, capacitance, and electrical resistance principles in production field conditions with two installation orientations, i.e., vertical (V) and horizontal (H), in two soils (silt loam and loamy sand) and two growing seasons (2017 and 2018). Performance parameters deduced from the 2017 datasets revealed that sensor type and …
