Cover Crop Effects on Corn in a Corn/Soybean Rotation

A research study was established in 2013 in a corn and soybean rotation with cover crops planted soon after each crop harvest. A variety of complex cover crop mixtures were evaluated ranging from single-specie to 7-specie mixtures. Cover crops were terminated in the spring prior to corn planting. Corn yield responded differently among the three years of the study. In general...

Cover Crop Effects on Soybean in a Soybean/Corn Rotation

A research study was established in 2011 in a soybean and corn rotation with cover crops planted soon after each crop harvest in the fall. A variety of complex cover crop mixtures were evaluated ranging from single specie to 7 specie mixtures. Cover crops were terminated in the spring soon after anthesis of the cool season cereal in the cover crop. Soybean yield responded...

Wheat Production

Wheat production in southeast Kansas is often limited due to high rainfall during the harvest. In some years, this high rainfall can exacerbate disease pressure, especially fungal infections. This study presents results from a test of fungicide applications to control Fusarium head blight (FHB) or scab in poor quality wheat.

Timing of Side-Dress Applications of Nitrogen for Corn in Conventional and No-Till Systems

Corn yields were affected by tillage and nitrogen (N) side-dress options in 2016. Corn yields were 12% greater with conventional tillage than with no-till. Side-dress applications of N at V10 resulted in greater corn yield than side-dress N applications at V6.

Double Crop Soybean After Wheat

Two double crop (DC) soybean studies were conducted at Ottawa, KS, during the 2016 growing season. Soybean cultivar Asgrow 4232 (MG 4.2) was planted immediately after two different wheat harvest timings (Study 1: early-wheat harvest 18-20% seed moisture content, and Study 2: conventional-harvest, 13-14% seed moisture content). Seven treatments were evaluated in each of the...

Timing of Side-Dress Applications of N for Corn in Conventional and No-Till Systems

In general, conventional tillage averaged nearly 40 bu/acre greater corn yield than no-till likely because of improved growth during the season. With conventional tillage, all side-dress treatments resulted in greater yield than with all N applied pre-plant. However, in lower-yielding no-till systems, the yield response to side-dress applications appeared to be greater for V10...

Corn Yield Response to Plant Populations

Corn hybrid development with a focus on drought tolerance has emerged in recent years, and producers have questions about their yield performance across a range of plant populations. A three-year study was conducted to determine the yield of corn hybrids across several plant populations. Corn hybrids responded differently across three different yield environments in 2013, 2014...

2015 Soybean Production in Southeast Kansas

Crop performance and yield varies as a function of the growing environment and soil properties within the field. Optimal soybean planting in southeast Kansas usually occurs from mid-May to mid-June for full-season or late-June to early-July for doublecropped soybean. Planting is timed to capture fall rains and cooler temperatures during critical periods of bean development and...

Identification of Yield-Limiting Factors in Southeast Kansas Cropping Systems

Crop performance and yield within production fields varies as a function of growing environment and soil properties within the field. Components contributing to yield in corn, wheat, and soybean production were examined through on-farm measurements of soil properties in southeast Kansas. Additional tests in research plots explored components contributing to yield in greater...

Soybean Production: Planting Date × Variety, Southeast Kansas

Optimal soybean planting in southeast Kansas usually occurs from mid-May to mid- June for full-season or late June to early July for double-cropped soybean. Planting is timed to capture fall rains and cooler temperatures during critical periods of bean development and yield formation to avoid midsummer heat and drought.

Corn Yield Response to Plant Populations

Corn hybrid development with a focus on drought tolerance has emerged in recent years, and producers have questions about their yield performance across a range of plant populations. A two-year study was conducted to determine the yield of corn hybrids across several plant populations. Corn hybrids responded differently in 2013 and 2014. In 2013, a lower yield environment...
