The growing season is flying by. We are three weeks out from Concord veraison and looking at the harvest doorstep three more weeks after that. It is a good time to finish up crop estimations, if you did not do them at 30 days post-bloom, and take some assessments of vine balance to decide when and where you will start harvesting. In this video, Dr. Terry Bates demonstrates how to use canopy NDVI at pre-bloom and pre-veraison with some directed field observations to generate spatial yield, vine size, and crop load maps in Concord vineyards.
