Wheat And Grain Sorghum In Four-Year Rotations, A. Schlegel, J. Holman, A. Burnett
Kansas Agricultural Experiment Station Research Reports
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 wheat-wheat-sorghum-fallow (WWSF), wheat-sorghum-sorghum-fallow (WSSF), and continuous wheat (WW). Soil water at wheat planting averaged about 9 in. following sorghum, which is about 3 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 sorghum …
Do Different Wheat Varieties Respond Differently To Nitrogen Rates In Terms Of Grain Yield And Grain Protein Concentration In Kansas?, N. Giordano, R. P. Lollato
Do Different Wheat Varieties Respond Differently To Nitrogen Rates In Terms Of Grain Yield And Grain Protein Concentration In Kansas?, N. Giordano, R. P. Lollato
Kansas Agricultural Experiment Station Research Reports
Nitrogen management in wheat can result in positive impacts on grain yield and grain protein concentration (GPC) if addressed correctly. The aim of this study was to compare whether different varieties responded differently in terms of grain yield and GPC to management of nitrogen (N) rate across different environments. Factorial field experiments were carried out in a split-plot design in four different Kansas locations to evaluate the combination of four N rates (whole plot, 0, 40, 80, and 120 lb N/a) and fourteen different commercially available winter wheat varieties (sub-plots). Grain yield and GPC were measured at harvest maturity. The …

Kansas Agricultural Experiment Station Research Reports
The efficiency of nitrogen (N) fertilizer management depends on rate, timing, placement, and source, but the benefits of an integrated program have not been clearly quantified, to our knowledge. This study aimed to investigate the effects of integrated N management on winter wheat grain yield, grain protein content, grain test weight, and biomass in Kansas. The study consisted of two N management treatments: Normal (single N application as UAN using broadcast nozzles with the absence of urea inhibitors); and Progressive (split N application into two timings using streamer bars with urease inhibitors). Both treatments had similar results in all variables …

Foliar fungicide can be an important tool in improving wheat yields, but its effectiveness is season- and variety-dependent. To evaluate the yield, test weight, and protein responses of different commercial winter wheat varieties to one foliar fungicide application around heading, we conducted a trial combining four winter wheat varieties and two fungicide management treatments in Manhattan during 2019–2020. The control treatment consisted of no fungicide application, and the alternative treatment consisted of 5 oz/a Absolute Maxx + NIS applied at heading. Varieties evaluated were Bob Dole, Larry, WB4269, and Zenda. The study was conducted under no-tillage practices following a previous …
Testing Efficacy Of Plant Growth Regulator Products For Enhanced Winter Wheat Grain Yield And Quality, R. M. Aiken
Testing Efficacy Of Plant Growth Regulator Products For Enhanced Winter Wheat Grain Yield And Quality, R. M. Aiken
Kansas Agricultural Experiment Station Research Reports
Experimental plant growth regulator compounds are expected to improve wheat grain yield by extending the duration of green leaf area and altering remobilization of stored carbohydrates. In order to evaluate this, plant growth regulator materials supplied by a commercial third party were applied to Tatonka hard red winter wheat during the mid-grain fill development stage. Overall, crop productivity increased. Compared to the control treatment, two of the treatment combinations had increased grain yield (13%, machine harvest; 31%, hand harvest); increased above-ground biomass (AGB, 8%); and increased harvest index (HI, 22%). Yield components also increased, including seeds/a (21%) and seed mass …
