| Sumario: | Helianthus tuberosus L. is a potentially
useful crop for bioetanol production, which will
be needed to add to gasoline used in Argentina
since 2010. Some studies indicate that 4500 l
of ethanol can be produced from 50 tons of
tubers. In this work we compared yield of two
Jerusalem artichoke cultivars using two types
of irrigation: urban waste water (UWW) and
ground water (GW). The research was conducted
in the Urban Waste Water Treatment
Plant of Obras Sanitarias Mendoza in Tunuyán
(33°32’89’’ S and 69°00’80’’ W). Ethanol potential
production was estimated from the amount
of fermentable carbohydrates in the tubers. Tuber
yield showed differences between type of
water treatment, being 177750 kg/ha in UWW
and 144000 kg/ha in GW. The potential to
produce ethanol was 15000 l in plots irrigated
with UWW and 13000 l in the GW irrigated. To
produce 1 l of ethanol from tubers, 11 kg will
be needed, considering that soluble solids in
tubers were about 16%.
