Location: Plant, Soil and Nutrition Research
Project Number: 8062-21000-052-008-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 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.
