Abstract

There are hundreds of alfalfa cultivars within 11 fall dormancy (FD) and 6 winter survival index (WSI) classifications. Currently, cultivar selection is sub-optimal due to the inability to match cultivar characteristics with planting site conditions. This project is quantifying climatic and soil conditions, FD and WSI requirements, and using GIS tools to map parameterized functions and crop modeling to predict yield.
