This workshop will require and assist all participants to develop an onboarding framework document that they can employ at their respective academic units/institutions. Topics to be discussed and included in such an onboarding guide include clear articulations of (1 ...


A Nonhomologous End-Joining Mutant For Neurospora Sitophila Research, Nicholas A. Rhoades, Elise K. Webber, Thomas M. Hammond Feb 2020

A Nonhomologous End-Joining Mutant For Neurospora Sitophila Research, Nicholas A. Rhoades, Elise K. Webber, Thomas M. Hammond

Fungal Genetics Reports

Disruption of the nonhomologous end-joining (NHEJ) pathway has been shown to increase the efficiency of transgene integration into targeted genomic locations of Neurospora crassa and other fungi. Here, we report that a similar phenomenon occurs in a second Neurospora species: N. sitophila. Specifically, we show that deletion of N. sitophila mus-51 increases the efficiency of targeted-transgene integration, presumably by disrupting NHEJ. Researchers interested in obtaining the N. sitophila mus-51 strains described in this study can obtain them from the Fungal Genetics Stock Center (FGSC, Kansas State University, Manhattan, KS).

Saline Experimental Range Dormant Season Wildfire: Short-Term Effect On Forage Production And Plant Composition, Keith R. Harmoney Jan 2020

Saline Experimental Range Dormant Season Wildfire: Short-Term Effect On Forage Production And Plant Composition, Keith R. Harmoney

Kansas Agricultural Experiment Station Research Reports

Rangeland wildfires in the southern plains may occur any time of year, but the low hu­midity, increasing temperatures, and dry and abundant fuel load of late winter and early spring can result in greater wildfire occurrence and severity. Fires that occur before the growing season remove standing residual vegetation and greatly reduce litter cover, so the soil surface may be left bare for several weeks or months before the onset of new pas­ture growth. Exposure of plant buds to cold temperatures during dormancy, soil water evaporation, and soil crusting from the force of falling precipitation and puddling may ...


An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger Jan 2020

An Efficient Stocking Strategy For Grazing Replacement Heifers, Keith R. Harmoney, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Even though Kansas native rangelands often have steep slopes or shallow soils not con­ducive to many other uses other than livestock grazing, native rangeland and perennial grassland acres in Kansas have been declining. Cropland acreage over this same time frame has increased, and rangelands have also become more fragmented by small ranch­ettes and urbanization. Producers may be looking to increase production efficiency on a shrinking forage land base. The use of intensive early stocking (IES) is one of the most efficient stocking strategies to produce beef on rangeland acres. The IES strategy has been widely used in eastern ...

Using Modified Intensive Early Stocking For Cow/Calf Production, Keith R. Harmoney, John R. Jaeger

Kansas Agricultural Experiment Station Research Reports

Intensive early stocking (IES) was introduced nearly a half century ago in eastern Kan­sas and has since been adopted as a major management tool to increase animal produc­tion, efficiency of production, and economic return on tallgrass rangelands. These in­creases have come almost exclusively by using IES with young stocker animals. Intensive early stocking and its gains have been proven effective repeatedly in published research. A similar modified IES (MIES) system has increased production efficiency of stocker animals on western Kansas rangelands. Perennial grassland acres for cattle produc­tion, as well as cattle numbers, are declining. Using management ...

Supplements were formulated to provide the same quantity of protein and energy per head, daily. Supplementation with the starch-based or fat-based supplement during the grazing phase resulted in higher (P < 0.05) grazing gains than feeding no supplement during all six years. In 2014, 2016, 2017, 2018, and 2019, grazing gains of steers supplemented with the starch-based or fat-based supplement were similar (P > 0.05). In 2015, steers ...


Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas Jan 2020

Including Legumes In Bermudagrass Pastures, J. L. Moyer, L. W. Lomas

Kansas Agricultural Experiment Station Research Reports

Bermudagrass is a productive forage species when intensively managed. However, it has periods of dormancy and requires proper management to maintain forage quality. Legumes in a bermudagrass sward could improve forage quality and reduce fertilizer usage; however, legumes are difficult to establish and maintain with the competitive grass. Clovers can maintain survival once established in bermudagrass sod, and may be productive enough to substitute for some N fertilization. This study was designed to compare dry cow performance on a bermudagrass pasture system that included ladino and crimson clovers (Legume) vs. bermudagrass alone (Nitrogen). Use of legumes in wheat-bermudagrass pastures did ...
