Proceedings Progress Report Northwest Center for Small Fruits Research 2006 Author: Schreiner, R. Paul Objectives of Proposed Research: The goals of this project for the next few years are: 1) to develop optimal tissue nutrient levels for N, P, and K in winegrapes that are based on physiological performance and fruit quality, 2) to identify the best tissue (leaf vs. petiole) and time of growing season to collect samples for specific nutrients (N,P,K) to diagnose sub-optimal concentrations, and 3) to identify indicators (physiological or visual) of sub-optimal nutrient levels that growers can utilize to better manage winegrape nutrition. Specific Objectives for 2006: 1) Apply different levels of N, P, and K to 4 year-old vines and monitor growth, nutrient status, gas exchange and photochemistry responses to treatments. 2) Assess impact of nutrient status on fruit quality.
