Role Of Soil Management In Control Of Soil-Borne Diseases, Gretchen F. Sassenrath, Christopher R. Little, Xiaomao Lin
Role Of Soil Management In Control Of Soil-Borne Diseases, Gretchen F. Sassenrath, Christopher R. Little, Xiaomao Lin
Kansas Agricultural Experiment Station Research Reports
Soil-borne diseases are a significant cause of crop yield reduction. Alternative soilmanagement methods can enhance the soil’s natural disease-controlling organisms. This study explores the effect of alternative production methods on a primary soybean disease, charcoal rot, caused by the fungus Macrophomina phaseolina. Treatments that could potentially enhance or reduce the disease pressure were implemented, and soil tests were conducted for nutrients, soil properties, and disease presence. Manure increased the nutrient levels in the soil, as expected, but did not influence disease control. Solarization increased the temperature within the plots and increased the number of colony-forming units (CFUs) of M. …

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.

Baseline Sensitivity To Demethylation Inhibitors Fungicides In Cercospora Spp. And Corynespora Spp. In Arkansas Soybeans, Evan Buckner, Alejandro Rojas
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Cercospora spp. and Corynespora spp. are two common foliar fungal pathogens in Arkansas and other soybean-producing areas. Two primary diseases caused by Cercospora spp. are Cercospora Leaf Blight (CLB, caused mainly by C. kikuchii) and Frogeye Leaf Spot (C. sojina). Over time, many fungicides used to combat these diseases have become ineffective as the pathogens have developed a resistance to them. The class of the fungicide in question is Triazoles [Demethylation Inhibitors (DMI)–FRAC 3]. Fifteen isolates consisting of Corynespora cassiicola, Cercospora sojina, and Cercospora flagellaris were tested to determine baseline sensitivities using serial dilutions (0, 0.01, 1, 10, 50 mg/L) …

Best Management Systems To Intensify Soybean Production, G. R. Balboa, I. A. Ciampitti
Kansas Agricultural Experiment Station Research Reports
The aim of this study was to evaluate different management systems to close the yield gap in soybean production. A soybean experiment was established in Scandia, KS, evaluating five management systems under both rainfed and irrigated conditions. For the 2017 season, dryland and irrigated average yields were similar (63–65 bu/a) due to herbicide injury on the irrigated phase. In both water scenarios, intensification (high input) increased yields compared with common practice (low input) systems. Under irrigation, a consistent response to a balanced nutrition program was documented.

Comparison Of Different Weed Control Technology Programs, D. E. Peterson, C. Thompson, C. L. Minihan
Kansas Agricultural Experiment Station Research Reports
The development of glyphosate-resistant weeds has greatly complicated weed control in soybeans. Roundup Ready 2 Xtend and Liberty Link soybeans provide an alternative postemergence herbicide options for weed control in soybeans. Liberty Link and Roundup Ready 2 Xtend programs provided better overall weed control and slightly higher yields than Roundup Ready 2 Yield programs in this experiment. Yields of Roundup Ready 2 Yield soybeans were likely influenced by more weed competition and possibly crop injury from spray tank contamination by dicamba. Dicamba injury from tank contamination to Roundup Ready 2 Yield soybeans decreased with each subsequent treatment and also with …

Tillage Study For Corn And Soybeans: Comparing Vertical, Deep, And No-Till, Eric Adee
Kansas Agricultural Experiment Station Research Reports
The need for tillage in corn and soybean production in the Kansas River Valley continues to be debated. The soils of the Kansas River Valley are highly variable, with much of the soil sandy to silty loam in texture. These soils tend to be relatively low in organic matter (<2%) and susceptible to wind erosion. Although typically well drained, these soils can develop compaction layers under certain conditions. A tillage study was initiated in the fall of 2011 at the Kansas River Valley Experiment Field near Topeka to compare deep vs. shallow vs. no-till vs. deep tillage in alternate years. Corn and soybean crops will be rotated annually. This is intended to be a long-term study to determine if soil characteristics and yields change in response to a history of each tillage system.
