Tillage Intensity In A Long-Term Wheat-Sorghum-Fallow Rotation, A. Schlegel, A. Burnett
Tillage Intensity In A Long-Term Wheat-Sorghum-Fallow Rotation, A. Schlegel, A. Burnett
Kansas Agricultural Experiment Station Research Reports
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-sorghum-fallow (WSF) rotation. In 2018, 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 …
Wheat Stubble Height On Subsequent Corn And Grain Sorghum Crops, A. Schlegel, L. Haag
Wheat Stubble Height On Subsequent Corn And Grain Sorghum Crops, A. Schlegel, L. Haag
Kansas Agricultural Experiment Station Research Reports
A field study initiated in 2006 at the Southwest Research-Extension Center near Tribune, KS, was designed to evaluate the effects of three wheat stubble heights on subsequent grain yields of corn and grain sorghum. Corn and sorghum yields in 2018 were greater than the long-term average. When averaged from 2007 through 2018, corn grain yields were 9 bu/a greater when planted into either high or strip-cut stubble than into low-cut stubble. Average grain sorghum yields were 6 bu/a greater in high-cut stubble than low-cut stubble. Similarly, water use efficiency was greater for high or strip-cut stubble for corn and high-cut …
Cover Crop Management Effects On Soil Water Content And Winter Wheat Yield In Dryland Systems, A. K. Obour, J. D. Holman, J. R. Jaeger
Cover Crop Management Effects On Soil Water Content And Winter Wheat Yield In Dryland Systems, A. K. Obour, J. D. Holman, J. R. Jaeger
Kansas Agricultural Experiment Station Research Reports
Integrating cover crop (CCs) 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 CC for forage on soil water content, …
