Project Type: Interagency Reimbursable Agreement
Start Date: Jul 1, 2024
End Date: Jun 30, 2027
Objective:
This proposal builds on our previous NIFA funded work to better understand the role of crop rotation diversity on whole system productivity. We created a database of agronomic management, crop yields, soils, and local weather data from 20 long-term crop rotation studies in North America to investigate crop rotation diversity effects on crop yields at the whole system and individual crops level under a range of growing conditions.
Approach:
1.1: This objective involves four steps: 1) define weather features that relate to different aspects of plant physiology for each crop and location, 2) quantify the sensitivity of each crop during critical developmental stages to each weather feature, 3) combine weather features and sensitivity scores from each crop in a rotation to create rotation-level vulnerability scores, and 4) compare vulnerability scores between simple and complex rotations.
