DEMONSTRATING UTILITY IN TRELLIS TENSION MONITORING
Project Number: 5358-21000-041-19
Specific Cooperative Agreement
Start Date: Jan 05, 2010
End Date: Sep 30, 2012
Statistical analyses of 7-year database from Trellis Tension Monitors (TTM) in Washington state and three-year database from TTM installations in California, to determine 1) spatial distribution needed for yield estimation with TTMs; 2) accuracy of yield estimation; 3) accuracy of detecting key grapevine phenological stages from the continuous tension trace; and 4) accuracy of yield estimation under physically constrained and open-ended TTM systems.
Complete field data collection; compute classic univariate descriptors; define linear and nonlinear models; complete geostatistical characterization of yield at research sites; and model yields from dynamic trellis tension values. Documents SCA with BioDataManagement.
