Brief Project Summary:

Modern soybean cultivars are more active later in the growing season than older cultivars, especially in regard to leaf retention, accumulation of nitrogen (N), phosphorus (P), and sulfur (S), and remobilization of N, P, and S. These advancements join together to improve yield and nutrient removal. Project objectives are to: determine the duration and the rate of seed fill during late soybean development, especially after R6 (full seed) until harvest; and determine the opportunities to enhance seed fill (e.g., higher daily gain, extended seed fill duration), thus improving grain yield through synergies in nutrient supply and foliar protection.

Information And Results
Project Deliverables

Preliminary results from 2015 season will be presented at Extension winter workshops, meetings, and conferences of producers, Extension educators, and crop professionals across Indiana. Conclusions from the two experiments in 2015 and 2016 will be shared with Extension audiences in presentations, newsletters, and websites. The graduate student will publish the thesis chapters for each trial, which will be submitted for publication in the Agronomy Journal.

Final Project Results

Update:
Final results will be updated.

Final results will be updated.

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.
