- •
Cellulosic biofuels may offer a low water-use alternative for cold desert farmers.
- •
We monitored production, weed resistance and root features of nine potential crops.
- •
With low irrigation, cool-season grasses performed better than warm-season grasses.
- •
Fine root abundance was correlated with more biomass and fewer weeds.
- •
Elytrigia elongata, Leymus cinereus and Bothriochloa ischaemum performed best.
