A study was initiated in 2018 to collect preliminary data to quantify nitrous oxide (N2O) emissions from dryland grain sorghum in western Kansas. Results indicate that the greatest flux of N2O occurred within the first 14 days after fertilization when plant uptake was minimal and soil moisture was elevated. During this time period, the timing and amount of rainfall was critical with respect to N2O flux. Nitrous oxide flux during the fallow phase was negligible. The cumulative emissions factor for fertilizer-derived N2O estimated for Colby (~0.3%) is well below the Intergovernmental Panel …

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

In this study, we conducted a pilot experiment to estimate missing rainfall records from root-zone soil moisture information recorded at Kansas Mesonet stations. Soil moisture is recorded at depths of 5, 10, 20, and 50 cm using the Campbell Scientific CS655 soil water reflectometer. Hourly rainfall and soil moisture data from mid- August 2017 to mid-May 2018 were taken from three stations (Lakin, Manhattan, and Hays) of …
Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage, E. A. Adee
Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage, E. A. Adee
Kansas Agricultural Experiment Station Research Reports
Trends from a tillage study conducted since 2011 have shown no clear differences between tillage systems for either corn or soybeans in lighter soils under irrigation. One year out of seven years has shown a yield advantage for either corn or soybeans for any tillage system, which appears to be related to environmental conditions experienced during the season. Averaged across all years of the study, the treatments with deep tillage either every or every-other year had about 3% higher corn yields, and soybeans had up to a 3% yield increase with some form of tillage.

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 Kansas and …

Timing Of Side-Dress Applications Of Nitrogen For Corn In Conventional And No-Till Systems, D. W. Sweeney, D. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Corn yield and yield components were affected by tillage and nitrogen (N) side-dress application options in 2019. Average corn yields were 15% greater with conventional tillage than with no-till. Yields were improved by either splitting N rate between pre-plant and side-dress at the V10 growth stage or adding additional side-dress N as compared with applying 150 lb/a pre-plant.

Kansas Agricultural Experiment Station Research Reports
In corn (Zea mays L.), breeding and selection for grain yield over time has been accompanied by a simultaneous increase in plant nitrogen (N) uptake. The understanding of plant N dynamics has attracted attention due to the environmental concerns related to N losses coming from fertilization. This research study was implemented to 1) describe N uptake and allocation dynamics, and 2) quantify fertilizer recovery efficiency across late-N strategies. Two field experiments (one under irrigation and one rainfed) were conducted at the Ashland Bottoms Research Farm, KS, during 2017. Three hybrids with different year of release and three N scenarios …
Water Use And Productivity Of Corn And Grain Sorghum In Long-Term Crop Sequences, R. M. Aiken
Water Use And Productivity Of Corn And Grain Sorghum In Long-Term Crop Sequences, R. M. Aiken
Kansas Agricultural Experiment Station Research Reports
Dryland corn and grain sorghum showed similar water productivity of grain and above-ground biomass, relative to respective growing periods, at the apparent yield frontier. The yield frontier indicates the maximum productivity for a given amount of water use. This similarity in productive response to water supply provides a foundation for improved precipitation use. Yield gaps relative to the yield frontier appear substantial. Water supply during the grain filling period was the primary driver of feed grain crop productivity, and was affected more by available soil water at pollen shed than by precipitation during grain-fill or available water at maturity. Grain …

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 …

Wheat Variety-Specific Grain Yield Response To Plant Density Under Intensive Management Conditions In Western Kansas, R. P. Lollato, K. Mark, B. R. Jaenisch
Kansas Agricultural Experiment Station Research Reports
Seeding rate determines the first yield component of field crops, which is the plant population. However, wheat is less responsive to plant populations than other crops due to the high plasticity in tillering potential, and this responsiveness depends on resource availability. The objective of this project was to evaluate winter wheat population, grain yield, and grain test weight responses to seeding rate and its interaction with variety in a highly managed production system where manageable stresses were limited. Experiments evaluating the response of the wheat varieties ‘Joe,’ ‘WB-Grainfield,’ ‘Langin,’ and ‘LCS Revere’ to seeding rates ranging from 200,000–1,000,000 seeds per …

Testing Label Restrictions On Seeding Timings Of Tall Fescue And Kentucky Bluegrass After Herbicide Application, Dani Mcfadden, Jared Hoyle, Steve Keeley, Zane Raudenbush
Kansas Agricultural Experiment Station Research Reports
During a lawn renovation, weeds are often a major problem because they grow more aggressively than seedling turf. Turfgrass seedlings need starter fertilizer and plenty of water for proper establishment, which makes an ideal environment for weeds to thrive as well. With current herbicide label restrictions, there are limited weed control strategies during the critical establishment period. Research trials were initiated in the fall of 2019 in Manhattan, KS, to determine if tall fescue (Schedonorus arundinaceus) and Kentucky bluegrass (Poa pratensis) could be seeded into a stand at different intervals after herbicide application before restrictions on …
