Perennial Warm-Season Grass Forages Impact On Cow-Calf Profitability In The Fescue Belt, Kyle A. Brazil, Patrick D. Keyser, Andrew P. Griffith, Christopher N. Boyer, J. Travis Mulliniks

Journal of Applied Farm Economics

Incorporating a perennial warm- season grass (WSG) into tall fescue (Lolium arundina-ceum [Schreb.] Darbysh.) forage systems in the fescue belt can help avoid the effects of fescue toxicosis on beef cattle (Bos taurus) reproduction and animal performance and provide forage during summer when fescue production is low. However, little information is available on the economics of incorporating WSG into fescue-based forage systems. We developed a simulation model to compare profitability of three forage systems—100% tall fescue, 70% tall fescue/30% bermudagrass (Cynodon dactylon), and 70% tall fescue/ 30% switchgrass (Panicum virgatum)—while also comparing spring- …

Forage Accumulation Of Spring And Summer Cover Crops In Western Kansas, L. M. Simon, A. K. Obour, J. D. Holman, S. K. Johnson, K. L. Roozeboom

Kansas Agricultural Experiment Station Research Reports

Intensification of no-till dryland cropping systems in western Kansas with cover crops (CCs) may provide important ecosystem services while also supplying annual forage for livestock. Two experiments were initiated in 2015 and 2016 near Brownell, KS, to determine the forage production potential of spring and summer CCs in a winter wheat-grain sorghum-fallow crop rotation. Cover crops were mechanically harvested as hayed forage to a height of 6 inches or mob-grazed with yearling heifers (weighing approximately 1000 lb each) stocked at 3 head/acre/day. Forage accumulation was determined for the hayed treatment using a small plot forage harvester, and samples of the …

Estimating Annual Forage Yields With Plant Available Water And Growing Season Precipitation, J. Holman, A. Obour, A. Schlegel, T. Roberts, S. Maxwell

Kansas Agricultural Experiment Station Research Reports

Forage production is important for the western Kansas region’s livestock and dairy industries and has become increasingly important as irrigation-well capacity declines. Forages require less water than grain crops and may allow for increased cropping intensity and opportunistic cropping. Being able to estimate forage production is important for determining forage availability versus forage needs. Data from several studies were used to quantify annual forage yield response to plant available water (PAW) at planting and growing season precipitation (GSP). In addition, water use efficiency was quantified. Forages evaluated included winter triticale, spring triticale, and forage sorghum.

Dual Use Of Cover Crops For Forage Production And Soil Health In Dryland Crop Production, A. K. Obour, J. D. Holman, L. M. Simon, S. K. Johnson

Kansas Agricultural Experiment Station Research Reports

Integrating a cover crop (CC) into dryland crop production in the semiarid central Great Plains (CGP) can provide several ecosystem benefits. However, CC adoption is slow and not widely popular in the CGP because CCs utilize water that other­wise would be available for the subsequent cash crop. Grazing or haying CCs can provide economic benefits to offset revenue loss associated with decreased crop yields when CCs are grown ahead of a cash crop. Objectives of the current research were to 1) determine forage production of CC mixtures, and 2) evaluate the impacts of removing CCs for forage on subsequent crop …

Forages are important for the region’s livestock and dairy industries and are becoming increasingly important as irrigation capacity and grain prices decrease. Forages require less water than grain crops and may allow for increased cropping system intensity and op-opportunistic cropping. A study was initiated in 2012 at the Southwest Research-Extension Center near Garden City, KS, comparing several 1-, 3-, and 4-year forage rotations with no-tillage and minimum-tillage. Data presented are from 2013 through 2018. Tillage …

Cattle Preference For Annual Forages, J. K. Farney

Kansas Agricultural Experiment Station Research Reports

Many plant species that are available to use as cover crops also have potential as for­age for cattle. With this array of options it can be daunting to decide which plants to establish to meet goals as either a cover crop, forage, or for both. Therefore, the purpose of this study was to identify the annual forages fed to cattle in the fall, winter, or sum­mer that cattle preferred. To summarize, grasses were the most highly preferred forage for cattle regardless of grazing period. Low glucosinolate brassicas such as ‘Graza’ forage radish was the most highly preferred brassica that was …

Kansas Agricultural Experiment Station Research Reports

Forage sorghum (Sorghum bicolorL.) and sorghum × sudan (Sorghum bicolor sssp. Drummondii) are important annual forages in the High Plains. Advancements in brown mid-rib (BMR) cultivars will likely affect forage yield and nutritive values. A study was initiated in 2017 at the Southwest Research-Extension Center near Garden City, KS, comparing one variety each of BMR and non-BMR forage sorghum and sorghum × sudan cultivars. Forage type and growth stage affected yield and nutritive value, and occasionally there was an interaction between forage type and maturity.

Integrated Grain And Forage Rotations, J. D. Holman, A. Obour, T. Roberts, S. Maxwell

Kansas Agricultural Experiment Station Research Reports

Interest in growing forages and reducing fallow has necessitated research on soil, water, and crop yields in intensified grain/forage rotations. Fallow stores moisture, which helps stabilize crop yields and reduces the risk of crop failure; however, only 25 to 30% of the precipitation received during the fallow period of a no-till wheat-sorghum-fallow rotation is stored. . The remaining 75 to 70% precipitation is lost, primarily due to evaporation. Moisture storage in fallow is more efficient earlier in the fallow period, when the soil is dry, and during the winter months when the evaporation rate is lower. It may be possible …

Integrated Grain And Forage Rotations, J. D. Holman, A. Obour, T. Roberts, S. Maxwell

Kansas Agricultural Experiment Station Research Reports

Producers are interested in growing forages in rotation with grain crops. Many producers are interested in diversifying their operations to include livestock or grow feed for the livestock industry. By integrating forages into the cropping system producers can take advantage of more markets and reduce market risk. Forages require less water to make a crop than grain crops, so the potential may exist to reduce fallow by including forages in the crop rotation. Reducing fallow through intensified grain/forage rotations may increase the profitability and sustainability compared to existing crop rotations.

This study was started in 2013, with crops grown in-phase …

Evaluating Multispecies Cover Crops For Forage Production, C. Davis, D. Presley, J. K. Farney, G. F. Sassenrath

Kansas Agricultural Experiment Station Research Reports

Cover crops offer potential benefits for improving soil health, but establishment and management costs can be expensive. One way for farmers to recover these costs is to graze the forage, which benefits producers by integrating crop and animal production. More information is needed on the potential forage quantity and quality for grazing livestock of cover crops and mixed species of cover crops. Researchers have suggested that different plant species complement each other, but additional work is needed to determine how best to balance forage production and how competitive the various species are when added to a mix. Sixteen treatments were …

Selection Of Pathways To Foraging Sites In Crop Fields By Flightless Canada Geese, Troy M. Radtke, Charles D. Dieter

Human–Wildlife Interactions

Geese, especially when they are flightless, can cause significant crop damage. We determined the effects of shoreline characteristics on foraging site selection by flightless Canada geese (Branta canadensis) in South Dakota. Distance from edge of crop field to wetland and visual obstruction by vegetation were important determinants of pathway selection by geese. Geese used crop fields for foraging that were closer to water than unused fields. Geese accessed those fields along pathways with less visual obstruction by vegetation than unused pathways. Our data suggest that this distance of crops to wetlands is the most important shoreline characteristic determining …
