The effect of a previous crop and its residue left on the field before the next crop is a consequence of soil water usage and residue quality. We evaluated the grain yield of forty winter wheat varieties, as well as soil bulk density, soil water content, and previous crop’s residue C:N ratio in three neighboring fields near Solomon, KS. Wherein these three fields, winter wheat was no-tilled following a previous crop of either 1) soybean; 2) cover crop mix (legume and cereal); or 3) winter wheat. The mix of cover crops consisted of pearl millet, sorghum sudan, and sunn hemp. …

A long-term cover crop experiment was established in 2007 at Ashland Bottoms near Manhattan, KS, to determine the effect of cover crops and nitrogen (N) rates on subsequent corn growth and yield in a wheat-corn-soybean rotation. Treatments included chemical fallow, double crop soybean, different cover crops (cereal rye,crimson clover, a mix of cereal rye and crimson clover, and a diverse mix of seven species) planted in late summer after wheat harvest, and five N rates (0, 40, 80, 160, and 240 lb/acre) applied to the subsequent corn crop. Yield responded differently to N rate depending on cover crop …

The widespread evolution of herbicide-resistant (HR) kochia and Palmer amaranth warrants the use of alternative ecological-based strategies for weed management in no-tillage (NT) dryland cropping systems in western Kansas. A field study was established in the fall of 2020 at Kansas State University Agricultural Research Center near Hays, KS, to determine the impact of fall-planted cover crop (CC) mixture on 1) kochia and Palmer amaranth suppression (density and biomass reduction), and 2) Palmer amaranth emergence dynamics in subsequent grain sorghum. A CC mixture of winter triticale, winter pea, radish, and rapeseed was planted in wheat stubble in the fall of …

Evaluation Of Warm Season Annual Forages For Livestock: Biomass And Cost Of Production, J. K. Farney, M. E. Reeb, Z. T. Buessing, K. Malone, G. F. Sassenrath
Kansas Agricultural Experiment Station Research Reports
Seventeen warm season annual forage options were evaluated as livestock feed to be grazed, hayed, ensiled, or left as a cover crop. Treatments were planted in mid-May and terminated in late September with one harvest for silage, two hay cuttings, and three grazing rotations. One additional treatment was unharvested to serve as a cover crop. Biomass production and cost to produce final outputs were determined. Even with restricted rainfall during the summer months in 2020, the growth for the chosen forage options was at least 1,500 lb of dry matter (DM) per acre, with the exception of sunflowers that had …
Evaluating Single And Multi-Species Summer Cover Crops For Biomass Yield, J. K. Farney, G. F. Sassenrath
Evaluating Single And Multi-Species Summer Cover Crops For Biomass Yield, J. K. Farney, G. F. Sassenrath
Kansas Agricultural Experiment Station Research Reports
Cover crops have multiple benefits to integrated agricultural production systems. However, information is needed on best species and mixes to use. In this one-year study, the single species grass cover crops produced the most biomass. Spring forage peas did not perform well as a summer cover crop, yielding the same biomass as the fallow areas. Adding collards to the mixtures generally reduced total biomass production compared to single species of grasses alone. Total biomass production was affected by the number of plants in the mixture. Yields of grass-only plots were ~868 lb of dry matter (DM) per acre more than …
Biomass Production Of Single Species Cover Crop, G. F. Sassenrath, J. K. Farney
Biomass Production Of Single Species Cover Crop, G. F. Sassenrath, J. K. Farney
Kansas Agricultural Experiment Station Research Reports
Cover crops can benefit agricultural production by improving soil health and productivity, reducing weeds, and providing biomass for grazing. In this one-year study, biomass production was measured in 17 different single species summer cover crops and a fallow control. Overall, grass species produced more biomass than brassicas, with legumes, broadleaves, and fallow yielding intermediate amounts of biomass. Within the grass species, pearl millet, brown midrib (BMR) sorghum, and sorghum sudan produced more biomass than proso millet; German millet and browntop millet had intermediate biomass production. Within the brassicas, both brown and yellow mustards produced more biomass than collards. There was …

This study was implemented to examine the effects of cover crops and mineral phosphorus (P) fertilizer application on water quality and soil health parameters. The experiment was established in 2014, at the Kansas Agricultural Watershed (KAW) field research facility, Ashland Bottoms Research Farm, Kansas State University, Manhattan, KS. The experiment was a 2 × 3 factorial design with two cover crop treatments (with and without) and three phosphorus fertilizer treatments (none, spring injected P, and fall broadcast P). Measures of nutrient demand (enzyme activity), microbial metabolic activity (soil respiration), and labile carbon (potassium permanganate oxidized carbon) were taken to assess …

Kansas Agricultural Experiment Station Research Reports
The objective of this study was to quantify the effects of cover crops and different fertilizer management techniques on the amount of nutrients being removed and recycled in the soil system. This study was conducted at Ashland Bottoms, KS, from 2014-2016. A 2 × 3 factorial design with three replicates was utilized in this study. The fertilizer management treatments included a control of 0 lb/a P2O5, along with fall broadcast and spring injected applications of P2O5based on a build and maintain recommendation system. Results show that total uptake of K2O …

Cover Crop Effects On Soybean In A Soybean/Corn Rotation, D. E. Shoup, I. A. Ciampitti, J. Kimball, Gretchen Sassenrath
Kansas Agricultural Experiment Station Research Reports
A research study was established in 2011 in a soybean and corn rotation with cover crops planted soon after each crop harvest in the fall. A variety of complex cover crop mixtures were evaluated ranging from single specie to 7 specie mixtures. Cover crops were terminated in the spring soon after anthesis of the cool season cereal in the cover crop. Soybean yield responded differently among the four years of the study. In an extreme drought year of 2012, the unplanted check yielded 29.4 bu/a. Soybean yield was significantly reduced by 4.2 and 3.4 bu/a in treatments with wheat or …

Cover Crop Effects On Corn In A Corn/Soybean Rotation, D. E. Shoup, I. A. Ciampitti, J. Kimball, Gretchen Sassenrath
Kansas Agricultural Experiment Station Research Reports
A research study was established in 2013 in a corn and soybean rotation with cover crops planted soon after each crop harvest. A variety of complex cover crop mixtures were evaluated ranging from single-specie to 7-specie mixtures. Cover crops were terminated in the spring prior to corn planting. Corn yield responded differently among the three years of the study. In general, 2014 and 2016 showed a similar trend of decreased corn yield as the complexity of cover crop specie mixtures increased. Significant corn yield losses ranged from 8.6 to 15.1 bu/a across all cover crop treatments in 2014. In 2016, …
