Brief Project Summary:
A recent verbal survey of North Carolina soybean stakeholders indicated three core areas of interest for applied soybean research: using planting date to maximize soybean yield, appropriate maturity group selection based on planting date, and population adjustments across diverse planting dates. This project seeks to provide locally generated data on these priorities. Research efforts generate information on ideal planting date for soybeans and collect data to evaluate dates of insurance coverage for soybeans, identify the appropriate soybean maturity group to be used across a wide range of planting dates, determine what soybean population should be used across various planting date and soybean maturity group combinations and shares results.

Project Summary

A recent verbal survey of North Carolina soybean stakeholders indicated three core areas of interest for applied soybean research that include: using planting date to maximize soybean yield, appropriate maturity group selection based on planting date, and population adjustments across diverse planting dates. This project seeks to provide locally generated data on these priority areas. This research will be conducted across North Carolina (5-6 locations/year) for three years in an effort to ask these research questions under diverse environmental conditions. We will target planting soybeans every two-weeks at each location from mid-March through mid-August. At each planting date, one soybean variety from each soybean maturity group (II-VIII) will be planted. Five populations will be tested within each maturity group at each plating date (75,000, 100,000, 125,000, 150,000, 175,000 seeds/acre). Results will be disseminated to various North Carolina stakeholders at grower meetings, field days, via electronic media, and through extension publications.

Project Objectives

1. Generate information for North Carolina producers on ideal planting date for soybeans and collect data RMA might need to evaluate dates of insurance coverage for soybeans in North Carolina

2. Identify the appropriate soybean maturity group to be used across a wide range of planting dates in North Carolina

3. Determine what soybean population should be used across various planting date and soybean maturity group combinations in North Carolina

4. Extend results to County Extension Agents, soybean producers, and other soybean stakeholders throughout North Carolina

Benefit To Soybean Farmers

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.
