Effects Of Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer
Effects Of Various Grazing Systems On Grazing And Subsequent Finishing Performance, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
MaxQ tall fescue, a wheat-bermudagrass double-crop system, and a wheat-crabgrass double-crop system have been three of the most promising grazing systems evaluated at the Kansas State University Southeast Agricultural Research Center in the past 20 years, but these systems have never been compared directly in the same study. The objective of this study was to compare grazing and subsequent finishing performance of stocker steers that grazed these three systems.
Effects Of Interseeding Ladino Clover Into Tall Fescue Pastures Of Varying Endophyte Status On Grazing Performance Of Stocker Steers, L. W. Lomas, J. L. Moyer
Effects Of Interseeding Ladino Clover Into Tall Fescue Pastures Of Varying Endophyte Status On Grazing Performance Of Stocker Steers, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
Tall fescue, the most widely adapted cool-season perennial grass in the United States, is grown on approximately 66 million acres. Although tall fescue is well adapted in the eastern half of the country between the temperate north and mild south, presence of a fungal endophyte results in poor performance of grazing livestock, especially during the summer. Until recently, producers with high-endophyte tall fescue pastures had two primary options for improving grazing livestock performance. One option was to destroy existing stands and replace them with endophyte-free fescue or other forages. Although it supports greater animal performance than endophyte-infected fescue, endophyte-free fescue …
Evaluation Of Tall Fescue Cultivars, J. L. Moyer
Evaluation Of Tall Fescue Cultivars, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
Tall fescue (Lolium arundinaceumSchreb.) is the most widely grown forage grass in southeastern Kansas. Its tolerance to extremes in climate and soils of the region is partly attributable to its association with a fungal endophyte,Neotyphodium coenophialum; however, most ubiquitous endophytes are also responsible for production of substances toxic to some herbivores, including cattle, sheep, and horses. Endophytes that purportedly lack toxins, but augment plant vigor have been identified and inserted into tall fescue cultivars adapted to the United States. These cultivars, and others that are fungus-free or contain a ubiquitous endophyte (i.e. Ky 31 EF and …
Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer, J. K. Farney
Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer, J. K. Farney
Kansas Agricultural Experiment Station Research Reports
Tall fescue is the major cool-season grass in southeastern Kansas. Perennial grass crops, as with annual row crops, rely on proper fertilization for optimum production; however, meadows and pastures are often under-fertilized and produce low quantities of low-quality forage. Even when new stands are established, this is often true. The objective of this study was to determine whether N, P, and K fertilization improves yields during the early years of a stand.
Tillage And Nitrogen Placement Effects On Yields In A Short-Season Corn/Wheat/Double-Crop Soybean Rotation, D. W. Sweeney, Dorivar Ruiz Diaz
Tillage And Nitrogen Placement Effects On Yields In A Short-Season Corn/Wheat/Double-Crop Soybean Rotation, D. W. Sweeney, Dorivar Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Many crop rotation systems are used in southeastern Kansas. This experiment was designed to determine the long-term effect of selected tillage and N fertilizer placement options on yields of short-season corn, wheat, and double-crop soybean in a rotation.
Timing Of Side-Dress Applications Of Nitrogen For Corn In Conventional And No-Till Systems, D. W. Sweeney, D. E. Shoup, Dorivar Ruiz Diaz
Timing Of Side-Dress Applications Of Nitrogen For Corn In Conventional And No-Till Systems, D. W. Sweeney, D. E. Shoup, Dorivar Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Environmental conditions vary widely in the spring in southeastern Kansas. As a result, much of the N applied prior to corn planting may be lost before the time of maximum plant N uptake. Side-dress or split applications to provide N during rapid growth periods may improve N use efficiency while reducing potential losses to the environment. The objective of this study was to determine the effect of timing of side-dress N fertilization compared with pre-plant N applications for corn grown on a claypan soil.
Response Of Soybean Grown On A Claypan Soil In Southeastern Kansas To The Residual Of Different Plant Nutrient Sources And Tillage, D. W. Sweeney, Philip Barnes, Gary Pierzynski
Response Of Soybean Grown On A Claypan Soil In Southeastern Kansas To The Residual Of Different Plant Nutrient Sources And Tillage, D. W. Sweeney, Philip Barnes, Gary Pierzynski
Kansas Agricultural Experiment Station Research Reports
Increased fertilizer prices in recent years, especially noticeable when the cost of phosphorus spiked in 2008, have led U.S. producers to consider other alternatives, including manure sources. The use of poultry litter as an alternative to fertilizer is of particular interest in southeastern Kansas because large amounts of poultry litter are imported from nearby confined animal feeding operations in Arkansas, Oklahoma, and Missouri. Annual application of turkey litter can affect the current crop, but information is lacking concerning any residual effects from several continuous years of poultry litter applications on a following crop. This is especially true for tilled soil …
Use Of A Fungicide To Reduce Stomatal Conductance For Production Of Sweet Corn Planted At Different Populations With Limited Irrigation, D. W. Sweeney, M. B. Kirkham
Use Of A Fungicide To Reduce Stomatal Conductance For Production Of Sweet Corn Planted At Different Populations With Limited Irrigation, D. W. Sweeney, M. B. Kirkham
Kansas Agricultural Experiment Station Research Reports
Sweet corn is a potential value-added, alternative crop for producers in southeastern Kansas. Corn responds to irrigation, and timing of water deficits can affect yield components. Even though large irrigation sources, such as aquifers, are lacking in southeastern Kansas, supplemental irrigation could be supplied from the substantial number of small lakes and ponds in the area. However, this may not be enough to improve the water use of the plant. Reducing stomatal conductance and adjusting seeding rate may also help reduce water stress and/or improve water use efficiency. The objective of this study was to determine the effect of limited …

Electrical Resistivity Tomography Of Claypan Soils In Southeastern Kansas, M. A. Mathis Ii, S. E. Tucker-Kulesza, G. F. Sassenrath
Kansas Agricultural Experiment Station Research Reports
Claypan soils cover approximately 10 million acres across several states in the central United States. The soils are characterized by a highly impermeable clay layer within the profile that impedes water flow and root growth. While some claypan soils can be productive, they must be carefully managed to avoid reductions to crop productivity due to root restrictions, water, and nutrient limitations. Clay soils are usually resistant to erosion but may exacerbate erosion of the silt-loam topsoil.
Soil production potential is the capacity of soil to produce at a given level (yield per acre). The productive capacity is tied to soil …

Healthy soil is the foundation of a sustainable agronomic production system. Microorganisms include bacteria (such as actinomycetes), fungi, and protozoa. Soil microorganisms, or microbes, exist in large numbers in soils and are critical for decomposition of organic residues and nutrient recycling. Soils with ample and diverse microbial populations can provide more essential nutrients for crop growth and development. Soil microbial properties are considered one of the major indicators of soil health.
Soil microbial properties can be measured by the activity and the composition of micro-organism populations. Phospholipid fatty acids (PLFA) are the primary components of cell membranes, they can be …

Growth, Forage Quality, And Economics Of Cover Crop Mixes For Grazing, J. K. Farney, G. F. Sassenrath, C. Davis, Deann Presley
Kansas Agricultural Experiment Station Research Reports
Cover crops offer many potential benefits to crop production. They diversify the plant system, increase soil organic matter, and reduce erosion. However, they can be expensive to plant. By grazing the cover crops, farmers can recover some of the expenses associated with growing cover crops. Grazing also increases the nutrients to the field, further enhancing the productive capacity of the soil.
Many cover crop mixtures are currently available on the market. However, it is not clear how useful the multi-species cover crops mixtures are, or their potential impact on economics of production. Moreover, many of the cover crop mixes being …

Kansas Agricultural Experiment Station Research Reports
“Soil health” is a term that is used to describe soil quality. The U.S. Department of Agriculture’s Natural Resources Conservation Service has defined soil health as “The continued capacity of soil to function as a vital living ecosystem that sustains plants, animals and humans (NRCS 2018).” For a farmer, soil health is the productive capacity of the soil, or the capacity of the soil to produce a crop or pasture. Healthy soils produce more and with better quality.
Soil health is critical for water and nutrient cycling. Soil captures rainwater and stores it for use by plants. Soil health is …

Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond
Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond
Kansas Agricultural Experiment Station Research Reports
This study was initiated in 1961 to determine responses of continuous corn and grain sorghum grown under flood irrigation to N, P, and potassium (K) fertilization. The study is conducted on a Ulysses silt loam soil with an inherently high K content. No yield benefit to corn from K fertilization was observed in 30 years, and soil K levels remained high, so the K treatment was discontinued in 1992 and replaced with a higher P rate.

Effect Of Drilled Seeding And Nitrogen Rate On Grain Sorghum Yield In Southwest Kansas, A. J. Foster, A. Schlegel, I. B. Cuvaca, J. D. Holman, I. A. Ciampitti, C. Thompson, D. Ruiz Diaz, R. Currie
Kansas Agricultural Experiment Station Research Reports
Drilled sorghum is normally done at the super-high population at row spacing between 7.5 and 10 inches, compared to rows planted at the spacing between 15 and 30 inches. Thompson (1983) growing super-thick sorghum at the Hays Research Station from 1974-1977, found that sorghum planted in narrow rows (12-18 in.) often produced higher yields than when planted in wide rows (24-40 in.). Norwood (1982) in Garden City repeated Thompson’s work and also came to the conclusion that yield of high population narrow row sorghum could exceed that of the low population-wide row when subsoil moisture and precipitation were adequate. The …
Integrating Half Rates Of Dicamba And Atrazine With Increasing Sorghum Density And Nitrogen Rate For Palmer Amaranth Control, I. B. Cuvaca, A. J. Foster, R. Currie
Integrating Half Rates Of Dicamba And Atrazine With Increasing Sorghum Density And Nitrogen Rate For Palmer Amaranth Control, I. B. Cuvaca, A. J. Foster, R. Currie
Kansas Agricultural Experiment Station Research Reports
Sorghum is an important crop in Kansas. However, in-season weed control options for sorghum are limited. This limitation is exacerbated by Palmer amaranth season-long interference and resistance to multiple herbicide modes of action.
This 2-year study investigated the ability of a contrasting combination of cultural and chemical practices to control Palmer amaranth while maintaining or improving sorghum grain yield. Particular research emphasis was to evaluate the effect(s) of integrating half rates of dicamba and atrazine applied as PRE with increasing sorghum density and nitrogen rate on Palmer amaranth control and grain yield in an irrigated environment.

Extent Of Larval Populations Of Turfgrass Insect Pests At Rocky Ford Turfgrass Research Center At Manhattan, Ks, Raymond A. Cloyd
Kansas Agricultural Experiment Station Research Reports
Many insect pests have a larval or grub stage that resides belowground and feeds on turfgrass roots (Potter, 1998; Vittum et al., 1999; Held and Potter, 2012). The major belowground insect pests (white grubs) associated with turfgrass throughout Midwestern states that are present in Kansas include: May/June beetles (Phyllophagaspp), masked chafers (Cyclocephalaspp), and bluegrass billbug (Sphenophorus parvulus) (Miller et al., 2013). However, there is limited information on the annual occurrence of these insect pests affiliated with the common turfgrass species planted in Kansas, including zoysiagrass (Zoysia japonica) and Kentucky bluegrass (Poa …
Urban Lawn Microclimates Affect Reference Evapotranspiration, Kenton W. Peterson, Dale J. Bremer, Jack D. Fry
Urban Lawn Microclimates Affect Reference Evapotranspiration, Kenton W. Peterson, Dale J. Bremer, Jack D. Fry
Kansas Agricultural Experiment Station Research Reports
Grass reference evapotranspiration (ETo) obtained from weather stations in open locations is often used to estimate irrigation requirements of turfgrass in local or regional urban lawns. However, the environments of urban lawns are often altered by surrounding buildings, trees, etc., to form various microclimates that may alter evapotranspiration (ET). Our research, which placed weather stations in urban lawns and nearby open swards of turfgrass, revealed ETowas 41% lower in residential lawn microclimates than in nearby open turfgrass swards. Less ET within urban lawns than in nearby open swards suggests using standard historical weather data to estimate …

Evaluating Zoysiagrass-Tall Fescue Mixtures In Kansas, Mingying Xiang, Jack D. Fry, Megan M. Kennelly
Kansas Agricultural Experiment Station Research Reports
Water conservation is increasingly important when selecting turfgrasses. Zoysiagrass (Zoysia japonica), a C4 grass, is more drought resistant than C3 grasses. However, there is some resistance to the use of zoysiagrass in lawns and golf courses due to its extended dormant period when turf is brown. The objective of this study was to evaluate mowing height, and tall fescue seeding rate and time for establishment of a mixed stand with seeded zoysiagrass. Seeding zoysiagrass and tall fescue together in June generally resulted in a less uniform mixture than seeding zoysiagrass in June and then seeding tall fescue in …

Brown Patch Occurrence In A Zoysiagrass-Tall Fescue Polystand Compared To A Tall Fescue Monostand, Mingying Xiang, Jack D. Fry, Megan M. Kennelly
Kansas Agricultural Experiment Station Research Reports
Research has demonstrated that polystands of zoysiagrass and tall fescue can be established successfully, with the potential to provide a high quality turfgrass stand with reduced inputs. Our objective was to determine whether mixing zoysiagrass with tall fescue will reduce brown patch severity while maintaining overall acceptable quality. Studies were established at the Rocky Ford Turfgrass Research Center in Manhattan, KS. In the split-plot design, natural infection byRhizoctoniasolanior a fungicide-treated control was the whole plot treatment factor and species (tall fescue monostand and the zoysiagrass/tall fescue mixture) were subplots. During July and August 2016 and 2017, when …

2013 National Turfgrass Evaluation Program Bermudagrass Test: 2013–2017 Summary Report, Linda R. Parsons, Michael J. Shelton, Jason J. Griffin, Jared A. Hoyle
2013 National Turfgrass Evaluation Program Bermudagrass Test: 2013–2017 Summary Report, Linda R. Parsons, Michael J. Shelton, Jason J. Griffin, Jared A. Hoyle
Kansas Agricultural Experiment Station Research Reports
Kansas represents the northernmost region in the central United States where bermudagrass can be successfully grown as a perennial turfgrass. Historically, few cultivars that have both acceptable quality and adequate cold tolerance have been available to local growers. Because new introductions are continually being selected for improved hardiness and quality, both seeded and vegetative types need regular evaluation to determine their long-range suitability for use in Kansas.
