Strategic Tillage Effects on Crop Yield and Soil Properties and Dryland Crop RotationsThis study evaluated strategic tillage (ST) to control HR weeds and improve crop yields in an otherwise long-term no-till (NT) soil. Treatments were five crop rotations: 1) continuous winter wheat (Triticum aestivum L.) (WW); 2) wheat-fallow (WF); 3) wheat-sorghum (Sorghum bicolor L.)-fallow (WSF); 4) continuous sorghum (SS); and 5) sorghum-fallow (SF) as main plots. The sub-plot were reduced tillage (RT), continuous NT, and ST of NT. Results showed tillage (ST or RT)... A. Obour, J. Holman, L. Simon, A. Schlegel |
4. Long-term Forage Rotation Yields, Soil Water Use, and ProfitabilityForages are important for the region’s livestock industry and are becoming increasingly important as irrigation capacity and grain prices decrease. Forages require less water than grain crops and may allow for increasing cropping system intensification and opportunistic cropping. A study was initiated in 2012 at the Southwest Research-Extension Center near Garden City, KS, comparing several 1-, 3-, and 4-year forage rotations with no-tillage and minimum-tillage. Data presented are from 2013... J. Holman, A. Obour, A. Schlegel, L. Simon |
5. Long-term Cover Crop Effects on Soil Organic Carbon, Nitrogen Stocks, and Water Stable Aggregates in the Semiarid Central Great PlainsGrowing cover crops (CC) in semiarid dryland cropping systems in the central Great Plains (CGP) may provide several benefits to soil health. This study examined long-term CC management effects on soil health in a no-till winter wheat (Triticum aestivum L.)–grain sorghum (Sorghum bicolor L.)–fallow (WSF) cropping system in southwestern Kansas. The experimental design was a split-split-plot randomized complete block with four replications. Main plots were... L. Simon, A. Obour, J. Holman, K. Roozeboom |

Split-plot design was used with 3.6 x 9.1 m experimental plots and four replicates. Tillage was main plot and micronutrient fertilizer was sub-plot. Tillage treatments included conventional and no-till. Fertilizer treatments included SUL4R-PLUS® (Ca & S), SUL4R-PLUS®B+Zn... C. Lim, C. Chen, C. Kowatch-carlson, B. Franck, T. Gross, R. Brown |
7. Soil Properties Affected by Grazing and Tillage of Annual ForagesNo-till (NT) management of annual crop production systems increases precipitation capture and storage. However, compaction with annual livestock grazing and the development of herbicide resistant weeds present challenges to long-term NT. An on-farm study was established in 2016 near Jetmore, KS to investigate the influence of annual tillage with a sweep plow compared to NT in a grazed continuous winter triticale production system. Forage productivity as well as weed density and soil properties... P. Mauler, J. Holman , A. Obour , L. Simon, K. Roozeboom |
8. Stacking Nutrient 4Rs on Potato and WheatThe 4 Rs of nutrient management are a set of research-based guidelines for farmers to use when applying fertilizers to their crops. The aim of the 4 Rs is to improve the sustainability of major cropping systems and the environment without compromising crop yield and quality. The objective for this project is to evaluate individual and stacked 4 R management practices and how they intersect. We conducted this experiment on a Russet Burbank potato crop grown at a field near Grace, Idaho in 2020.... S.H. Stapley, N.C. Hansen, M.A. Yost, E.A. Woolley, B.G. Hopkins |
9. Lentil Inoculant, Potassium, Sulfur, and Micronutrient Effects on Yield and Protein in the Northern Great PlainsLentil (Lens culinaris Medikus) is an important crop, averaging more than 600,000 ac in MT and ND from 2016-20. However, relatively little is known about inoculant and fertility response in lentil in the U.S. northern Great Plains. The objective of this experiment was to evaluate the effect of rhizobial inoculant formulations (granular and seed-coat) and nutrient additions (K, S, and micronutrients), on lentil growth, yield, and seed protein. This study was conducted at six or seven university... P. Miller, C. Jones, S. Atencio, C. Chen, E. Eriksmoen, S. Fordyce, P. Lamb, M. Ostlie, J. Rickertsen, M.A. Grusak, M. Bourgault, B. Franck, P.

10. Combined Nitrogen with Magnesium or Zinc Effects on Sugarbeet Yield Sucrose Concentration, and Nutrient Uptake Under Conventional and No-till SystemsSugar beet (Beta vulgaris L.) is an important cash crop in the Lower Yellowstone River valley. Fertility, especially nitrogen (N) fertilizer, management is critical for sugar beet yield and sucrose concentration. While farmers are switching from a conventional tillage method to a no-till system for sugar beet cultivation, nitrogen (N) fertilizer application timing might need to be adjusted. Furthermore, micronutrients may enhance sugar beet yield and sucrose concentration. A two-year... C. Chen, M. Etesami, M. Abdelhamid |
