Tillage Study For Corn And Soybean: Comparing Vertical, Deep, And No-Till, E. A. Adee
Tillage Study For Corn And Soybean: Comparing Vertical, Deep, And No-Till, E. A. 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 are 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.
Effects Of Seed Treatment On Sudden Death Syndrome Symptoms And Soybean Yield, E. A. Adee
Effects Of Seed Treatment On Sudden Death Syndrome Symptoms And Soybean Yield, E. A. Adee
Kansas Agricultural Experiment Station Research Reports
Sudden death syndrome (SDS) is a soybean disease that perennially limits yields in the Kansas River Valley. The presence of soybean cyst nematode (SCN) and saturated soils have been implicated in contributing to the severity of the disease. Selecting varieties with some degree of tolerance to SDS is the only cultural practice that can potentially reduce the severity of SDS and improve yields. Variety selection alone, however, cannot improve the production of soybeans to make them profitable. The challenge of trying to manage irrigation scheduling to avoid saturated soils further complicates efforts to increase productivity with irrigation while still avoiding …
Effects Of An Experimental Seed Treatment From Dupont On Sudden Death Syndrome Symptoms And Soybean Yield, E. A. Adee
Effects Of An Experimental Seed Treatment From Dupont On Sudden Death Syndrome Symptoms And Soybean Yield, E. A. Adee
Kansas Agricultural Experiment Station Research Reports
Sudden death syndrome (SDS) is a soybean disease that perennially limits yields in the Kansas River Valley. Soybean cyst nematode (SCN) and saturated soils contribute to the severity of the disease. Selecting varieties with some degree of tolerance to SDS is the only cultural practice that can reduce the severity of SDS and improve yields. Variety selection alone, however, doesn’t necessarily make soybean production profitable; an added complication is managing irrigation scheduling to avoid saturated soils. A study with seed treatments applied to soybean was conducted at the Kansas River Valley Experiment Field in 2014, with treatments applied to two …
Soybean Sudden Death Syndrome Influenced By Macronutrient Fertility On Irrigated Soybean In A Corn/Soybean Rotation, E. A. Adee, D. Ruiz Diaz
Soybean Sudden Death Syndrome Influenced By Macronutrient Fertility On Irrigated Soybean In A Corn/Soybean Rotation, E. A. Adee, D. Ruiz Diaz
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 2014, with corn planted in odd years. We observed a relationship between the P rate applied during the corn years and the severity of sudden death syndrome (SDS) in 2014 soybean.
