Location: Plant, Soil and Nutrition Research
Project Number: 8062-21000-052-006-A
Project Type: Cooperative Agreement
Start Date: Oct 1, 2023
End Date: Sep 30, 2025
Objective:
The objective of this research is to determine the potential impact of maintaining more N in maize fields on crop yield, resilience, and sustainability in the US under current and future climates (AIMS1 & 2). This is complemented by a gene and allele discovery pipeline that aims at reducing N in kernels (AIM 3), remobilizing N back to the roots (AIM 4), and understanding the relationship of variation in stover composition with nitrogen loss (AIM 5). By the end of the year, we should have a clear effective modeling of these nitrogen traits from plant to farm, candidate genes and pathways identified across four trait areas, potential implications for policy, and a set of priority traits and strategies that can be advanced in future public and private partnerships.
Approach:
The Cooperator will focus their research on AIM 1,4, and 5. The Cooperator will participate in the assessment of the impact of diverse maize hybrids on nitrous oxide emissions by growing trials for measurement and coordinating drone measurements. Moreover, the collaborator will contribute germplasm and expertise to map the regulation of nitrogen remobilization and lead the evaluation of candidate genes for N remobilization. In addition, the Cooperator will participate in the prediction of stover nitrification inhibition with genomic information and multi-spectral imaging.
