Assessing The Impact Of The 4r Nutrient Management On Nitrogen Use Efficiency In Corn, Pedro Morinigo, Dorivar A. Ruiz Diaz
Assessing The Impact Of The 4r Nutrient Management On Nitrogen Use Efficiency In Corn, Pedro Morinigo, Dorivar A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Determining the best management practices for nitrogen (N) fertilizer application to corn is crucial to achieving the objectives of the 4R of nutrient stewardship. Although producers have a wide range of options regarding N fertilization, identifying the right rate, source, placement, and timing (4R) can significantly impact productivity and nitrogen use efficiency. Our objectives were to evaluate the nitrogen agronomic efficiency (NAE), and the corn grain yields as affected by different rates, sources, placements, and timing methods of N fertilizer application under rainfed and irrigated conditions in Kansas. Two rainfed locations in Riley and Republic counties and two irrigated locations …
Soil Phosphorus Fractions After Long-Term Fertilizer Placement In Different Kansas Soils, M. J. Coelho, D. A. Ruiz Diaz
Soil Phosphorus Fractions After Long-Term Fertilizer Placement In Different Kansas Soils, M. J. Coelho, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Phosphorus (P) fertilizer placement can affect the long-term dynamics and forms of P, and the overall soil P pools. These changes can vary by soil type, and affect P uptake and use efficiency by crops. The objective of this study was to evaluate the changes in the labile P fractions in three Kansas soil types under P fertilizer placements (broadcast versus deep band) after ten years of crop rotation. Three field studies were conducted at Scandia, Ottawa, and Manhattan. Three treatments were evaluated: 1) a control with no P fertilizer application and two fertilizer treatments (80 lb P2O …

Large-Scale Dryland Cropping Systems, A. Schlegel
Large-Scale Dryland Cropping Systems, A. Schlegel
Kansas Agricultural Experiment Station Research Reports
A large-scale dryland cropping systems research and demonstration project at the Southwest Research-Extension Center near Tribune, Kansas, evaluated two summer crops (corn and grain sorghum) along with winter wheat in crop rotations varying in length from 1 to 4 years. The rotations were continuous grain sorghum, wheat-fallow, wheat-corn-fallow, wheat-sorghum-fallow, wheat-corn-sorghum-fallow, and wheatsorghum- corn-fallow. The objective of the study is to identify cropping systems that enhance and stabilize production in rain-fed locations to optimize economic crop production. Averaged across the past 7 years, wheat yields ranged from 22 to 25 bu/a and were not affected by length of rotation. Corn and …
Nitrogen And Phosphorus Fertilization Of Irrigated Grain Sorghum, A. Schlegel, H. D. Bond

(Abstract only. Link to:http://newprairiepress.org/kaesrr/vol1/iss3/6/) Article is nearly identical to
Long-Term Nitrogen and Phosphorus Fertilization of Irrigated Grain Sorghum, previously published in Kansas Fertilizer Research 2015, included in this PDF.
Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated grain sorghum in western Kansas. In 2014, N applied alone increased yields 49 bu/a, whereas N and P applied together increased yields up to 81 bu/a. Averaged across the past 10 years, N and P fertilization increased sorghum yields up to 73 bu/a. Application of 40 lb/a N (with P) was …

Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond
Kansas Agricultural Experiment Station Research Reports
(Abstract only. Link to: http://newprairiepress.org/kaesrr/vol1/iss3/7/)
Article is nearly identical to Long-Term Nitrogen and Phosphorus Fertilization of Irrigated Corn, previously published in Kansas Fertilizer Research 2015, included in this PDF.
Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated corn in western Kansas. In 2014, N applied alone increased yields 58 bu/a, whereas P applied alone increased yields only 12 bu/a. Nitrogen and P applied together increased yields up to 152 bu/a. This is slightly above the 10-year average, when N and P fertilization increased corn yields up to 146 bu/a. Application …
Long-Term No-Till In A Wheat-Sorghum-Fallow Rotation, A. Schlegel, L. Stone
Long-Term No-Till In A Wheat-Sorghum-Fallow Rotation, A. Schlegel, L. Stone
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 2014, available soil water at wheat planting was 2 inches greater for no-till (NT) than for reduced-tillage (RT) or conventional tillage (CT). For grain sorghum in 2014, available soil water at planting was greatest with RT and least with CT. Averaged across the 14-year 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 14 years, NT wheat yields were 5 bu/a greater than RT and …
Teff Grass Response To Nitrogen Fertilization, J. D. Holman, D. H. Min, S. Maxwell
Teff Grass Response To Nitrogen Fertilization, J. D. Holman, D. H. Min, S. Maxwell
Kansas Agricultural Experiment Station Research Reports
Teff, a warm season annual grass native to Africa, is gaining popularity as a forage crop in the United States. Little information regarding nitrogen fertilization is available for teff grass production. This field experiment was conducted to evaluate teff grass response to varying nitrogen fertilization rates under dryland conditions. There was no yield response to increasing nitrogen rate or nitrogen source applied.
