Tillage Intensity In A Long-Term Wheat-Sorghum-Fallow Rotation, A. Schlegel
Tillage Intensity In A Long-Term Wheat-Sorghum-Fallow Rotation, A. Schlegel
Kansas Agricultural Experiment Station Research Reports
Grain yields of wheat and grain sorghum increased with decreased tillage intensity in a wheat-sorghum-fallow (WSF) rotation. In 2016, available soil water at wheat and sorghum planting was greater for reduced till (RT) than no-till (NT) and least for conventional till (CT). Averaged across the 16-yr study, available soil water at wheat and sorghum planting was similar for RT and NT and about 1 inch greater than CT. Averaged across the past 16 years, NT wheat yields were 4 bu/a greater than RT and 7 bu/a greater than CT. Grain sorghum yields in 2016 were 15 bu/a greater with long-term …
Wheat And Grain Sorghum In Four-Year Rotations, A. Schlegel, J. D. Holman, C. Thompson
Wheat And Grain Sorghum In Four-Year Rotations, A. Schlegel, J. D. Holman, C. Thompson
Kansas Agricultural Experiment Station Research Reports
In recent years, cropping intensity has increased in dryland systems in western Kansas. The traditional wheat-fallow system is being replaced by wheat-summer crop-fallow rotations. Is more intensive cropping feasible with concurrent increases in no-till? Objectives of this research were to quantify soil water storage, crop water use, and crop productivity of 4-year and continuous cropping systems.

Seeding Rate For Dryland Wheat, A. Schlegel, J. D. Holman, L. Haag
Kansas Agricultural Experiment Station Research Reports
Four winter wheat varieties (PlainsGold Byrd, Limagrain T158, Syngenta TAM 111, and WestBred Winterhawk) were planted at five seeding rates (30, 45, 60, 75, and 90 lb/a) in the fall of 2014, 2015, and 2016 at Colby, Garden City, and Tribune, KS. The objective of the study is to identify appropriate seeding rates for dryland winter wheat in western Kansas. Averaged across varieties, a seeding rate of 60 lb/a seemed to be adequate at all locations in 2015. However, with higher yields in 2016, a higher seeding rate (75 lb/a) was beneficial. Although yields were less in 2017 than 2016, …

Kochia, Russian thistle, and quinoa control was excellent regardless of treatment or rating date. Sunflower control at 10 DAPT was very good when Anthem Maxx (pyroxasulfone + fluthiacet) + Solstice (fluthiacet + mesotrione) + atrazine and glyphosate were applied EPOST, while green foxtail control was 94% with the same treatment at 68 DAPT. Palmer amaranth and green foxtail control at 68 DAPT was 93 and 91%, respectively, when SureStart II (acetochlor + flumetsulam + clopyralid) + atrazine and glyphosate were applied PRE followed by glyphosate POST. All herbicide-treated corn yielded 34 to 69 bu/a more grain than the untreated control. …
