Synopsis Water use efficiency of grain crops in Nebraska was increased an average 29% by optimum fertilizer treatment. This enhancement was especially associated with yield increase, and was accompanied by an approximate extra inch of water consumption by the crop. Corn and sorghum evidenced a greater capability for extracting deep subsoil moisture than small grains.
