Role Of Soil Management In Control Of Soil-Borne Diseases, Gretchen F. Sassenrath, Christopher R. Little, Xiaomao Lin Jan 2024

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. …


Soybean Sudden Death Syndrome Influenced By Macronutrient Fertility On Irrigated Soybeans In A Corn/Soybean Rotation, Eric Adee, Dorivar Ruiz Diaz, C. R. Little Jan 2017

Soybean Sudden Death Syndrome Influenced By Macronutrient Fertility On Irrigated Soybeans In A Corn/Soybean Rotation, Eric Adee, Dorivar Ruiz Diaz, C. R. Little

Kansas Agricultural Experiment Station Research Reports

The effects of nitrogen (N), phosphorus (P), and potassium (K) fertilization on a corn/ soybean cropping sequence were evaluated from 1983 to 2016, with corn planted in odd years. There was a negative relationship between the P rate applied during the corn years and the severity of sudden death syndrome (SDS) in 2014 and 2016 soybean.

Sudden Death Syndrome And Soybean Planting Date, Eric Adee, C. R. Little, I. A. Ciampitti

Kansas Agricultural Experiment Station Research Reports

The effect of planting date on severity of sudden death syndrome (SDS) and yield was evaluated for the second year in two studies at the Kansas River Valley experiment fields in 2016. One study was established to promote SDS and the other to minimize SDS. In both studies the severity of SDS was greatest with the earlier planting dates. The yield was greatest with the earlier planting date, except for the most susceptible variety. The severity of SDS was not as great as had been observed in previous years. There is a very positive benefit to planting in early May …
