A Bayesian approach for analyzing crop yield response data with limited treatments

Agrosystems, Geosciences &Environment, Volume 6, Issue 2, June 2023., 2023
Abstract This paper proposes a Bayesian multilevel modeling approach to incorporate response parameters from published studies into crop yield response estimation procedures when nonlimiting or limiting treatment levels are omitted or limited in agronomic experiments.

Regional switchgrass carbon sequestration estimates from high‐frequency eddy covariance and Mesonet observations

Agrosystems, Geosciences &Environment, Volume 6, Issue 1, March 2023., 2023
Abstract Monitoring net ecosystem carbon dioxide (CO2) exchange (NEE) using eddy covariance (EC) flux towers is quite common, but the measurements are valid at the scale of tower footprints. Alternative ways to quantify and extrapolate EC‐measured NEE across potential production areas have not been explored in detail.

Sunn hemp planting date effect on growth, biomass accumulation, and nutritive value in southeastern Wyoming

Crop Science, Volume 61, Issue 6, Page 4447-4457, November/December 2021., 2021
Abstract Sustainablesuccess of the Northern High Plains (NHP) crop and livestock industry is limited by market accessibility, infertile soils, short growing seasons, and availability of high nutritive value, low‐cost feed. Adoption of the tropical legume, Crotalaria juncea L.

Grain sorghum production: Influence of planting date, hybrid selection, and insecticide application

Agrosystems, Geosciences &Environment, Volume 4, Issue 2, 2021., 2021
Abstract Grain sorghum [Sorghum bicolor (L.) Moench] has been a valuable crop for the southern Great Plains due to its ability to overcome the high temperatures and sporadic rain events common in the region. Optimizing production practices has always been critical for grain sorghum to overcome these environmental challenges.

Quantifying the effects of switchgrass (Panicum virgatum) on deep organic C stocks using natural abundance 14C in three marginal soils

GCB Bioenergy, Volume 12, Issue 10, Page 834-847, October 2020., 2020
Perennial bioenergy crops have been shown to increase soil organic carbon (SOC) stocks, potentially offsetting anthropogenic C emissions. We measured differences in SOC stocks under switchgrass and conventional crops at three sites in Oklahoma to greater than 1 m depth.

Closely related winter wheat cultivar performance in U.S. Great Plains acid soils

Agronomy Journal, Volume 112, Issue 5, Page 3704-3717, September/October 2020., 2020
Abstract Aluminum‐tolerant wheat (Triticum aestivum L.) cultivars are often employed to damper the yield‐limiting impacts of Al toxicity in acidic soils. Tolerance is often facilitated by the Al‐activated malate transporter 1 (ALMT1) gene, which increases anion permeability of wheat roots and exudes malate in the presence of Al.

Effect of topdress nitrogen rates applied based on growing degree days on winter wheat grain yield

Agronomy Journal, Volume 112, Issue 4, Page 3114-3128, July/August 2020., 2020
Abstract The majority of in‐season nutrient management decisions for numerous crops are based on subjective morphological scales. The objective of this study was to establish whether a numerical scale based on growing degree days (GDDs > 0) utilizing weather science, could be used for N management in winter wheat (Triticum aestivum L.).

Nitrogen management impact on winter wheat grain yield and estimated plant nitrogen loss

Agronomy Journal, Volume 112, Issue 1, Page 564-577, January/February 2020., 2020
Abstract Method of N application in winter wheat (Triticum aestivum L.) and its impact on estimated plant N loss has not been extensively evaluated. The effects of the pre‐plant N application method, topdress N application method, and their interactions on grain yield, grain protein concentration (GPC), nitrogen fertilizer recovery use efficiency (NFUE)

Nitrogen Requirements of Ethiopian Mustard for Biofuel Feedstock in South Dakota

Agronomy Journal, Volume 111, Issue 3, Page 1304-1311, March 2019., 2019
Core Ideas Brassica carinata is a new crop in the Northern Great Plains. Best management practices including N fertilizer recommendations should be developed. Seed yield and oil yield were optimized at 84 kg ha–1 of applied N fertilizer. Seed oil concentration decreased linearly at a rate of 0.26 g kg–1 for every 1 kg ha–1 increase in N rate.

Impact of Late‐Season Herbicide Applications on Winter Canola Yield and Seed Quality

Agrosystems, Geosciences &Environment, Volume 2, Issue 1, Page 1-7, 2019., 2019
Core Ideas The application of glyphosate during early reproductive growth resulted in significant declines in yield. Decreased yields with late‐season herbicides were associated with an increased number of aborted pods; however, this may not be the only factor contributing to the yield decline.
