Factors Affecting White Bass Abundance In Two Missouri River Reservoirs, William J. Radigan, Mark J. Fincel Jun 2019

Factors Affecting White Bass Abundance In Two Missouri River Reservoirs, William J. Radigan, Mark J. Fincel

The Prairie Naturalist

Annual angler harvest of white bass (Morone chrysops) increased from 1985–2005 in Lake Oahe and Lake Sharpe, two mainstem Missouri River reservoirs in South Dakota. In 2006, harvest rates dropped appreciably in both reservoirs and remained low through 2015. It is hypothesized that a confirmed 2005 columnaris disease outbreak led to reduced annual angler harvest of white bass from both reservoirs. Mean annual angler harvest prior to the outbreak (1985–2005) in Lake Oahe decreased 65% and in Lake Sharpe decreased 57% post outbreak (2006–2015). To assess potential causes of sustained decreased adult white bass abundance in the reservoirs, …

The field of human resource development has twin obligations to promote the performance of organizations and the satisfaction and welfare of all workers. Nevertheless, agriculture appears to be an understudied industry in the field, despite this obligation and the potential for suffering experienced by workers performing crop work. This case study sought to understand the process through which a single agricultural operation fosters optimal conditions for workers engaged in labor-intensive crop production. This study found employees experienced better treatment compared to other agricultural operations, and that conditions were rich in both intrinsic and extrinsic factors. Intrinsic factors were marked by …


Harvest Method, Cultivar, And Time Of Swathing Effects On Yield And Oil Content Of Winter Canola, M. J. Stamm, S. J. Dooley, K. L. Roozeboom Jan 2019

Harvest Method, Cultivar, And Time Of Swathing Effects On Yield And Oil Content Of Winter Canola, M. J. Stamm, S. J. Dooley, K. L. Roozeboom

Kansas Agricultural Experiment Station Research Reports

Producers want to achieve the highest yield and oil content possible using either swathing or direct cutting to harvest winter canola. Multi-year experiments were conducted to evaluate the effects of harvest method (swathing versus direct cutting) and cultivar on seed moisture, yield, and oil content; and to evaluate the effects of swathing timing on yield and oil content. The harvest method experiments were conducted for two seasons at the Redd Foundation Field near Partridge, KS. The time of swathing experiments were conducted for two seasons near Manhattan, KS. In 2016 and 2017, harvest method had a significant effect on seed …
