Soil-borne diseases are a significant cause of reduction in crop yield. Alternative management of soils can enhance the natural disease-controlling organisms in the soil. This study explores the impact of alternative production methods on a primary soybean disease, charcoal rot, caused by the fungusMacrophomina phaseolina. Treatments that could potentially enhance or control the disease were implemented, and soil tests were conducted for nutrient and disease presence. Manure increased the nutrient levels in the soil, as expected, but did not impact the disease control. Solarization increased the temperature within the plots, and increased the number of colony forming units …

Appropriate management, with a longer growing season during reproductive growth stages, can increase biomass and yield in soybean. Our objective was to determine the impact of three planting dates, two seed populations, and three maturity groups on grain yield in southeast Kansas. However, due to the severe drought in 2022, with a total rainfall of 18.84 inches during the soybean growing season (55% lower than the 10-yr average), the growing conditions were very limited, resulting in an average yield of 1.7 bu/a.
