Soybean production in the southern Great Plains (SGP) faces challenges due to yield-limiting factors, including high temperatures and inconsistent precipitation. These conditions can lead to excess vegetative growth, similar to what occurs in crops like cotton. Management strategies utilizing plant growth regulators (PGRs) have been applied to control this excessive growth, yet there is limited information on methods to mitigate vegetative growth in soybeans through modifications to the apical meristem. Field trials conducted in 2022 and 2023 investigated the effects of altering the apical growth using Ascend SL, Compact, Cobra, Cygin Pro, and physical removal, with treatments applied at the V4 and R2 growth stages. This study highlights the significance of customized application strategies to enhance profitability under diverse environmental conditions. Ascend and Cygin Pro demonstrate improving yield stability under adverse climatic conditions. Both applications of Compact produced relatively stable yields across site years, while Cobra and physical removal methods necessitate careful consideration of timing to minimize yield losses. Further research is essential to optimize these management strategies for soybean production in the SGP.

We explore US beef cow-calf production in 2018 and estimate net returns, returns to scale, and technical efficiency associated with backgrounding versus nonbackgrounding by size and production system. We determine the relative profitability of cow-calf operations by type, region, and size. Results, using both stochastic production frontier analysis and data envelopment analysis, indicate that larger operations tend to be more scale and technically efficient than smaller operations. While larger operations may be more scale and technically efficient and have lower variable costs per cow, off-farm income helps smaller operations become competitive. The availability of detailed cost of production information in the 2018 Agricultural Resource Management Survey of cattle and calves survey also facilitates identifying competitiveness by region and size as well as important efficiency drivers.

Drought conditions in much of the western United States have improved, leading to opportunities for cow-calf producers to rebuild beef cow herds. Given lower beef cow herds, many producers will need to borrow funds to purchase replacement heifers. We investigate how financial positions are impacted by leveraged replacement heifer purchases. The results are useful to producers and bankers. We suggest alternatives for financially struggling producers, including delay rebuilding to avoid significantly increased financial stress
