Available water in the Mediterranean type of climate usually gets scarce during grain filling of wheat. A crop water based yield-predicting index towards anthesis would be useful. Most of the available plant water indices use measurements on leaves only and ignore other green plant parts. We measured the amount of water contained in the crop/area and related it to grain yield in combination with other parameters. Crop water/area was concluded to be the preferred term over biomass/area for accounting grain yield variance.
