Kansas Agricultural Experiment Station Research Reports
Beginning in 2012, research was conducted near Garden City and Tribune, KS, to determine the effect of a single tillage operation every 3 years on grain yields in a wheat-sorghum-fallow (WSF) rotation. Treatments included no-till, single tillage post wheat harvest in mid-August, and single tillage mid-June during the fallow phase. This study was revised with two additional more intensive tillage treatments since 2019. The two additional treatments were 1) two tillage operations during the fallow phase and 2) one tillage during fallow phase and one tillage post wheat harvest. Grain yield varied greatly by year and location. Wheat yields ranged …

In 1996, an effort began to quantify soil water storage, crop water use, and crop productivity on dryland systems in western Kansas. Research on 4-year crop rotations with wheat and grain sorghum was initiated at the Southwest Research-Extension Center near Tribune, KS. Rotations were wheatwheat- sorghum-fallow (WWSF), wheat-sorghum-sorghum-fallow (WSSF), and continuous wheat (WW). Soil water at wheat planting averaged about 9.1 in. following sorghum, which is about 3.8 in. more than the average for the second wheat crop in a WWSF rotation. Soil water at sorghum planting was only about 1.5 in. less for the second sorghum crop compared with …
Previous Crop Impacts Winter Wheat Sowing Dates, Available Water At Sowing, And Grain Yield, L. M. Simão, A. Patrignani, S. Cominelli, R. P. Lollato

Cropping systems choices can directly affect the sowing date for winter wheat, which is among the most important variables that determine attainable yields in the U.S. Central Great Plains. Our objective was to investigate the effect of the previous crop on winter wheat grain yield through the modulation of sowing date and its impact on plant available water at sowing, and temperatures during the critical period for yield determination. A no-tillage rainfed field experiment was established in 2019 at Ashland Bottoms, KS. Winter wheat was sown either after summer fallow, full-season soybean, double-cropped soybean, or corn—thus, resulting in a range …
Tillage Intensity In A Long-Term Wheat-Sorghum-Fallow Rotation, Lucas A. Haag, Amanda Burnett, Dewayne Bond, Jeffrey Slattery, Alan Schlegel

This study was initiated in 1991 at the Kansas State University Southwest Research-Extension Center near Tribune, KS. The purpose of the study was to identify the effects of tillage intensity on precipitation capture, soil water storage, and grain yield in a wheat-sorghum-fallow rotation. Grain yields of wheat and grain sorghum increased with decreased tillage intensity in a wheat-sorghumfallow (WSF) rotation. In 2022, available soil water at sorghum planting was greater for no-tillage (NT) than reduced tillage (RT), which was greater than conventional tillage (CT). For wheat there was a similar pattern as sorghum, with available soil water at wheat planting …
Chloride Fertilization’S Impacts On Kansas Winter Wheat Grain Yield During 2021-2022, Luiz O. Pradella, Jorge R. Soler, Romulo P. Lollato
Chloride Fertilization’S Impacts On Kansas Winter Wheat Grain Yield During 2021-2022, Luiz O. Pradella, Jorge R. Soler, Romulo P. Lollato

Previous work suggests that wheat can respond to chloride fertility in Kansas and other regions, but this response depends on Cl availability and the wheat variety. In this study, we aimed to identify and quantify the effects of chloride fertilizer application in different areas and winter wheat varieties across Kansas. Sixteen field experiments were conducted during the 2021–2022 growing season. All experiments were conducted in a split-plot design with Cl fertility levels as whole plot (0 or 20 lb Cl/a) and wheat variety as subplots, with either three or four replicates. One protocol evaluated 24 winter wheat varieties in three …

2023 Southeast Research And Extension Center Agricultural Research Report, J. K. Farney
Kansas Agricultural Experiment Station Research Reports
The 2023 Southeast Research and Extension Center Agricultural Research report includes research conducted in the areas of beef cattle management, cropping systems, and forage crops. Topics include various grazing and nutrient input for steers and heifers; wheat, soybean, and corn production practices and results, as well as soil health practices; and burning and nutrient practices along with efforts for improvement of native and tall fescue range grasses.
Does Winter Wheat Yield Response To Fungicide Application Depend On Nitrogen Management?, J. A. Romero Soler, L. O. Pradella, N. Giordano, G. Cruppe, R. P. Lollato
Does Winter Wheat Yield Response To Fungicide Application Depend On Nitrogen Management?, J. A. Romero Soler, L. O. Pradella, N. Giordano, G. Cruppe, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
Nitrogen and fungicide are among the more important management tools to increase wheat (Triticum aestivumL.) grain yield in Kansas. However, there is limited information on whether hard red winter wheat grain yield is impacted by the interaction of nitrogen rates and foliar fungicide application. Thus, our objective was to evaluate the effects of different N rates with or without a fungicide application at Feekes 10.5 on grain yield of two winter wheat genotypes with contrasting disease resistances to leaf and stripe rust. Eleven field experiments were established across Kansas using a factorial structure of two fungicide management options …
