Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage, E. A. Adee
Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Tillage, E. A. 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 out of seven 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.
Alternative Cropping Systems With Limited Irrigation, A. Schlegel, D. Bond
Alternative Cropping Systems With Limited Irrigation, A. Schlegel, D. Bond
Kansas Agricultural Experiment Station Research Reports
A limited irrigation study involving four cropping systems and evaluating four crop rotations was initiated at the Southwest Research-Extension Center near Tribune, KS, in 2012. The cropping systems were two annual systems (continuous corn [C-C] and continuous grain sorghum [GS-GS]) and two 2-year systems (corn- grain sorghum [C-GS] and corn-winter wheat [C-W]). In 2018, corn yields were similar for all rotations, although averaged across the past 6 years, corn yields were greater following wheat than following corn. There were no significant differences in grain sorghum yields in 2018, which was similar to the multi-year average. Wheat yields were near the …

Tillage And Nitrogen Placement Effects On Yields In A Short-Season Corn/Wheat/Double-Crop Soybean Rotation, D. W. Sweeney, D. Ruiz-Diaz
Kansas Agricultural Experiment Station Research Reports
In 2018, adding nitrogen (N) greatly improved average wheat yields with about a 10% increase with knife compared to broadcast application methods. Even though tillage did not affect wheat yields, soybean yield was about 10% greater with no-till.

Large-Scale Dryland Cropping Systems, A. Schlegel, L. Haag, A. Burnett
Kansas Agricultural Experiment Station Research Reports
This study was conducted from 2008–2018 at the Kansas State University Southwest Research-Extension Center near Tribune, KS. The purpose of the study was to identify whether more intensive cropping systems can enhance and stabilize production in rainfed cropping systems to optimize economic crop production, more efficiently capture and utilize scarce precipitation, and maintain or enhance soil resources and environmental quality. The crop rotations evaluated were continuous grain sorghum (SS), wheat-fallow (WF), wheat-corn-fallow (WCF), wheat-sorghum-fallow (WSF), wheat-corn-sorghum-fallow (WCSF), and wheat-sorghum-corn-fallow (WSCF). All rotations were grown using no-tillage practices except for WF, which was grown using reduced-tillage. The efficiency of precipitation capture …

Effects Of Grinding Corn With Different Moisture Concentrations On Subsequent Particle Size And Flowability Characteristics, M. B. Braun, K. M. Dunmire, C. E. Evans, C. R. Stark, C. B. Paulk
Kansas Agricultural Experiment Station Research Reports
The objective of this study was to determine the effects of whole corn moisture and hammermill screen size on subsequent ground corn moisture, particle size, and flow- ability. Whole yellow dent #2 corn was used for this experiment. Treatments were arranged as a 2 × 2 factorial design with two moisture concentrations (as-received and high) each ground using 2 hammermill screen sizes (1/8 and 1/4 in). Corn was ground using a laboratory scale 1.5 HP Bliss Hammermill (Model 6K630B) at 3 separate time points to create 3 replications per treatment. Increasing initial whole corn moisture was accomplished by adding 5% …
Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer
Effects Of Supplementation With Corn Or Dried Distillers Grains On Gains Of Heifer Calves Grazing Smooth Bromegrass Pastures, L. W. Lomas, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
A total of 150 heifer calves grazing smooth bromegrass pastures were used to compare supplementation with 0.5% of body weight per head daily of corn or dried distillers grains (DDG) in 2014, 2015, 2016, 2017, and 2018. Daily gains of heifers supplemented with corn or DDG were similar (P>0.05) in all years except 2018, when heifers supplemented with DDG had greater (P<0.05) gains than those supplemented with corn.
Pre-Plant Nitrogen Rate And Application Method And Side-Dress Nitrogen Rate Effects On Corn Grown No-Till On A Claypan Soil, D. W. Sweeney, D. Ruiz-Diaz
Pre-Plant Nitrogen Rate And Application Method And Side-Dress Nitrogen Rate Effects On Corn Grown No-Till On A Claypan Soil, D. W. Sweeney, D. Ruiz-Diaz
Kansas Agricultural Experiment Station Research Reports
Corn yield in 2018 was increased by about 5 bu/a with knife application of pre-plant nitrogen (N) fertilizer compared with broadcast application. Fertilizing with increasing rates of N applied pre-plant, at side-dress, or both had little effect on yield or yield components of corn in 2018.

Changes In Soil Nitrate And Ammonium During The Corn Growing Season As Affected By Nitrification Inhibitors, F. D. Hansel, D. A. Ruiz Diaz
Changes In Soil Nitrate And Ammonium During The Corn Growing Season As Affected By Nitrification Inhibitors, F. D. Hansel, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Nitrification inhibitors (NI) are used to delay the nitrification process, increasing nitrogen fertilization efficiency. The objective of this study was to evaluate the effect of NI on soil nitrate (NO3-N) and ammonium (NH4-N) content throughout the growing season for corn. The study was conducted at four locations (Manhattan, Scandia, Rossville, and Ashland, KS) during the 2017 and 2018 crop seasons. Most of the NI effects on soil NH4-N and NO3-N were observed early in the season and when the higher nitrogen (N) fertilizer rate was used. An increase in NO3-N …

Use Of Satellite Imagery To Predict Corn Phenology At A Regional Scale, L. Nieto, R. Schwalbert, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
Existing methods to report phenology are expensive, labor-intensive, time-consuming, and often not very accurate, especially at some specific crop growth stages. The objective of this study was to develop large-scale phenology models via utilization of satellite imagery data and machine learning techniques for the southwest (SW) agricultural crop reporting district of Kansas. Different satellite images collected from Landsat were utilized as the main input to obtain different vegetation indices (normalized difference vegetation index, NDVI; enhanced vegetation index, EVI; green chlorophyll vegetation index, GCVI; normalized difference water index, NDWI; and global vegetation moisture index, CVMI). Vapor Pressure Deficit (VPD), temperature, precipitation, …

Kansas Agricultural Experiment Station Research Reports
This experiment was conducted to determine the effect of feeding fumonisin (FUM) contaminated corn on growth performance of 20- to 60-lb nursery pigs. A total of 350 pigs (241 × 600; DNA, Columbus, NE; initially 19.6 lb) were used. Dietary treatments consisted of FUM-contaminated corn blended with relatively FUM-free corn to provide toxin (FB1 + FB2) of 7.2, 14.7, 21.9, 32.7, and 35.1 ppm. Experimental diets were fed in mash form for 28 d. There were 5 pigs per pen and 14 replicates per treatment. After weaning, pigs were fed common diets for 21 days before the experiment started. Then, …

In Exp. 1, a total of 350 pigs (241 × 600; DNA, Columbus, NE; initially 21.8 lb) were used. There were 5 pigs per pen and 14 replicates per treatment. After weaning, pigs were fed common diets for 21 d before the experiment started. Five dietary treatments were utilized and consisted of a positive control (low FUM), a negative control (approximately 50 to 60 ppm of FUM), and 3 other treatments as …

Kansas Agricultural Experiment Station Research Reports
This experiment was designed to evaluate the effects of die thickness and conditioning temperature on pelleting and starch characteristics in diets containing either conventional yellow dent or high amylase corn (Enogen®, Syngenta Seeds, LLC). Treatments were arranged as a 2 × 2 × 3 factorial of corn type (conventional and high amylase), die thickness (L:D 5.6 and 8.0), and conditioning temperature (165, 175, and 185°F). For the high amylase corn treatments, ground high amylase corn replaced conventional ground corn on a lb:lb basis. Diets were pelleted via steam conditioning (10 in × 55 in Wenger twin staff pre-conditioner, …
