Brief Project Summary:

Double-crop soybean is one way of increasing production and net return. The objective of this project is to evaluate different management treatments and their effect on double-crop soybean planted after wheat harvest and identify the main yield-limiting factors affecting crop productivity from a perspective of environment and management practices compared to full-season soybeans. The project is based on an all-encompassing experiment, comparing low input common practice, treatments that included all yield enhancing inputs (“kitchen sink” including higher fertility, pest control, row spacing, seed density), and treatments that excluded individual inputs from the “kitchen sink” treatment.

Key Benefactors:
farmers, agronomists, extension specialists, ag retailers

Information And Results
Project Deliverables

Identify best management practices on agronomics, seeding methods and crop protection practices that benefit yield and profitability of double crop systems.
Presentations of double crop current research and BMPs at professional Agronomy meetings and at Soybean related Extension Meetings.
Development of regional extension publications detailing BMPs for double crop systems in the Plains Region.
Survey current grower production practices and identification of areas of improved double-crop soybean management to improve production and/or profitability.

In the first year of the project, we will compile (identify, collect, and digitize data and reports) previous research and extension information on double crop soybean production in. Along with compiling past research on double crop soybean, producers will be surveyed on their current double crop soybean management. These producers will be tracked through the life of the project and their activities will be documented to their implementation of best management practices for double crop soybean.
In addition, data from double crop soybean research will be collected to help identify best management practices to increase profitability. Specific field research will be conducted at 3 locations in Kansas (Manhattan, Ottawa, and Parsons). Treatments to be evaluated include fertility, row spacing, plant population, and pest management .
Data from the research projects will be summarized and materials from the initial double crop soybean information search will be packaged into publications and presentations at producer meetings and scientific conferences.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
