crop_devnotes
Population based on 8 foot rows with 6 foot spacing of vines in row
Used 300 days to find annual neat units
Note: the between row cover names do not relect any mechanism in WEPS, so only one vineyard crop is available
Specif Leaf Area from: Wermelinger, B. and W. Koblet, 1990, Seasonal growth and nitrogen distribution in grapevine leaves, shoots and grapes. Vitis 29, 15-26
This was tested in Napa Valley and produces a typical table grape yield. The management rotation includes 2 prunings, one fruit thinning, and two leaf thinnings.
