Research Project: Physiology of Nitrogen Uptake and Optimal Partitioning in Potato Plants

Location: Vegetable and Forage Crops Production Research

Project Number: 5354-21660-003-03
Project Type: Specific Cooperative Agreement

Start Date: Sep 14, 2011
End Date: Sep 30, 2015

Objective:
Physiological basis for optimal nitrogen availability in potato rootzone during the growing season to enhance uptake efficiency and optimal partitioning into different plant parts.

Approach:
Field experiments will be conducted using different potato varieties under different irrigation and nitrogen management. The dynamics of nitrogen uptake and partitioning into different plant parts will also be investigate using 15N labeled fertilizer. In addition to evaluation of tuber yield and quality responses to different nitrogen management practices, soil and plant growth parameters will be measured to assist field validation of potato growth simulation model.
