Assessing Corn Response To Cover Crops And Nitrogen Fertilization In A No-Till, Three-Year Rotation In Northeast Kansas, Jessica GrüNberg, Alexis Correira, Kraig L. Roozeboom, Deann R. Presley, Peter J. Tomlinson
Kansas Agricultural Experiment Station Research Reports
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 …

Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage / Year 10, E. Adee
Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage / Year 10, E. Adee
Kansas Agricultural Experiment Station Research Reports
Trends from a tillage study conducted since 2011 have shown no clear differences between tillage systems for either corn or soybeans in lighter soils under irrigation. One year out of eight years has shown a yield advantage for either corn or soybeans for any tillage system, which appears to be related to environmental conditions experienced during the season. Averaged across all years of the study, the treatments with deep tillage either every or every-other year had about 4.5% higher corn yields, and soybeans had up to a 3.2% yield increase with some form of tillage.
Could The Use Of Nitrification Inhibitor Optimize The Nitrogen Use Efficiency Of Corn Production?, Pedro Morinigo, Dorivar A. Ruiz Diaz
Could The Use Of Nitrification Inhibitor Optimize The Nitrogen Use Efficiency Of Corn Production?, Pedro Morinigo, Dorivar A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Nitrogen (N) is an essential nutrient for corn production, higher grain yields are dependent on N fertilizer application. Substances like the nitrification inhibitors (NI) were created to increase yields, promote nitrogen use efficiency (NUE), and reduce N losses. The study was carried out in ten site-years in Kansas from 2017 to 2021, with the objective of evaluating the nitrogen agronomic efficiency (NAE) in corn with and without the use of NI and comparing corn grain yield, grain N uptake, and soil mineral nitrogen content with the use of the NI. Nitrogen fertilizer at the rates of 100, 150, and 200 …

Evaluation Of Plant Tissue Analysis To Assess Phosphorus Nutritional Status For Corn And Soybean, Gustavo A. Roa, Edmond B. Rutter, Dorivar A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Plant tissue samples can be used to assess nutrient concentrations and the response to phosphorus fertilization. This study aimed to identify critical phosphorus tissue concentrations for corn and soybean at different growing stages. The experiment was conducted at 23 locations for corn in 2021–2022 and 12 locations for soybean in 2017–2020 across Kansas. Tissue samples were collected from whole corn plants at the V6 stage, corn ear leaves at the R1 stage, and whole soybean plants at the V4 stage, and upper trifoliate leaves at the R2 soybean stage. Data from plots that received no phosphorus fertilization were used to …
Evaluating The Impact Of Long-Term Phosphorus Placement On Corn And Soybean Rotation Under Minimum Tillage System, Gustavo A. Roa, Dorivar A. Ruiz Diaz
Evaluating The Impact Of Long-Term Phosphorus Placement On Corn And Soybean Rotation Under Minimum Tillage System, Gustavo A. Roa, Dorivar A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Phosphorus (P) management is typically done with a focus on the long term, given its impact on soil fertility. The main objective of this study was to evaluate the effect of long-term P placement on corn and soybean yields under a minimum tillage system in Kansas. Long-term research trials were established in Scandia (irrigated field) and Ottawa (rainfed) in 2006. Fertilizer treatments were applied annually to corn, including broadcast, deep-band, and starter/deep-band at 40 lb/a of P2O5, with a control having no phosphorus fertilizer. Corn and soybean responded significantly to P fertilizer at both locations (compared …
Corn And Soybean Production – 2022 Summary, Gretchen F. Sassenrath, Jane Lingenfelser, Xiaomao Lin
Corn And Soybean Production – 2022 Summary, Gretchen F. Sassenrath, Jane Lingenfelser, Xiaomao Lin
Kansas Agricultural Experiment Station Research Reports
Soybean and corn varieties were tested in replicated field trials at the Southeast Research and Extension Center in Parsons through the Kansas State University variety testing program. In total, nine corn varieties and three maturity checks were tested. Fourteen full season and ten double-cropped soybean varieties were tested, with three maturity checks. Additionally, sorghum and sunflower varieties were tested. The 2022 summer crop growing season was challenging. High temperatures and low rainfall reduced crop production. Crop production was severely impacted by the hot, dry conditions, both across the state and in the cultivar trials at Parsons. No yield results are …
Improving Resilience Of Corn To Weather Through Improved Fertilizer Efficiency, Na Huang, Gretchen F. Sassenrath, Xiaomao Lin
Improving Resilience Of Corn To Weather Through Improved Fertilizer Efficiency, Na Huang, Gretchen F. Sassenrath, Xiaomao Lin
Kansas Agricultural Experiment Station Research Reports
Fertilization is a critical management tool to improve crop productivity. Corn requires more N fertilizer than some other crops, but the fertility needs of the crop vary based on the growing environment. In this study, we used a modeling approach to examine the historical record and delineate the interaction between fertilizer and weather on the sensitivity of corn yield to climate in southeastern Kansas. Providing optimal fertilizer can improve corn yield. However, too much fertilizer can be expensive and wasteful. This study demonstrated that the climate resilience of corn is moderated by how much fertilizer is applied. The model results …

Performance Of Corn Hybrids With Contrasting Maturity In Northeastern Kansas, L. N. Lingua, I. Massigoge, A. J. P. Carcedo, I. A. Ciampitti
Performance Of Corn Hybrids With Contrasting Maturity In Northeastern Kansas, L. N. Lingua, I. Massigoge, A. J. P. Carcedo, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Corn (Zea maysL.) hybrid selection is one of the most important agricultural management decisions made by farmers. Both genetic yield potential and adaptation to the local environment vary widely across corn hybrids, and have a direct impact on yield and input costs. This study compared the performance of corn hybrids with contrasting comparative relative maturity (CRM, referring to their growth cycle), to evaluate their differences in crop phenology, grain yield and its components—grain number and grain weight. The field experiment was conducted during the 2022 growing season in Manhattan, KS (U.S.), testing five commercial corn hybrids with contrasting …

Kansas Agricultural Experiment Station Research Reports
This experiment was conducted to determine the optimum feeding strategy of a modified corn protein product (MCP; P4000; Cargill Starches, Sweeteners, & Texturizers, Blair, NE) on growth performance and fecal dry matter of nursery pigs. A total of 360 barrows (DNA 200 × 400; initially 12.0 ± 0.14 lb) were used in a 42-d growth trial. Pigs were weaned at approximately 21 d of age, randomly allotted to pens in 1 of 2 weight blocks based on initial BW (initially 10.8 and 13.2 lb), and then allotted to 1 of 6 dietary treatments in a completely randomized design. There were …
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 …
