Strategies for improving water-use efficiency in western regions through increasing harvest index.. 4. Increase the total proportion of dry matter that is grain i.e. improve harvest index (e.g. early flowering varieties, delayed nitrogen, wider row spacing, low plant densities, minimising losses to disease, high HI varieties such as H45 , Hindmarsh , Wyalkatchem , Espada ).. Harvest index is calculated as the ratio of grain to total dry matter (and is sometimes expressed as a percentage);..
