Spring And Summer Cover Crop Effects On Dryland Wheat And Grain Sorghum Yields In Western Kansas, L. M. Simon, A. K. Obour, J. D. Holman, S. K. Johnson, K. L. Roozeboom
Spring And Summer Cover Crop Effects On Dryland Wheat And Grain Sorghum Yields In Western Kansas, L. M. Simon, A. K. Obour, J. D. Holman, S. K. Johnson, K. L. Roozeboom
Kansas Agricultural Experiment Station Research Reports
Incorporating cover crops (CC) to replace fallow in traditional dryland cropping systems in the semi-arid conditions of western Kansas has the potential to enhance soil health, suppress weeds, and increase precipitation use efficiency. The returns from haying or grazing can help cover costs of CC establishment and any reduction in yield from the subsequent grain crop. Two studies were initiated in 2015 and 2016 near Brownell, KS, to investigate dual-purpose spring and summer CC management effects on subsequent grain yields in a three-year no-till (NT) dryland winter wheat-grain sorghum-fallow cropping system. Cover crops were planted in early spring between grain …
Crop Assurance Strategies For Irrigated Grain Sorghum Production, F. R. Lamm
Crop Assurance Strategies For Irrigated Grain Sorghum Production, F. R. Lamm
Kansas Agricultural Experiment Station Research Reports
This sprinkler-irrigated study was conducted from 2018 to 2021 at the Kansas State University Northwest Research-Extension Center near Colby, KS, to evaluate four different water management strategies that could provide assurance of adequateyielding grain sorghum. The grain sorghum was grown on sites with good initial soil water at planting (>70% of field capacity within the 8-ft deep silt loam profile). Strategies were 1) No seasonal irrigation; 2) Irrigation of 100% of ET minus Rain after the boot stage through remainder of season; 3) Irrigation of 100% of ET minus Rain up to a limit of 6 inches; and 4) …
Firstact For Efficacy In Accase-Tolerant Grain Sorghum, R. S. Currie, P. W. Geier
Firstact For Efficacy In Accase-Tolerant Grain Sorghum, R. S. Currie, P. W. Geier
Kansas Agricultural Experiment Station Research Reports
The objective of this study was to compare FirstAct with several tank mix partners for efficacy in herbicide-tolerant grain sorghum. FirstAct (quizalofop) alone or in tank mixtures controlled Johnsongrass 94% or more. However, tank mixing FirstAct with any broadleaf herbicide was generally antagonistic to Palmer amaranth control. Minor sorghum injury was 5% or less by four weeks after postemergence treatment. Sorghum yields increased with all postemergence treatments except with atrazine alone.
