Energycane production may be limited by cold tolerance of germplasm. A mulch layer acts
as an insulator against freezing temperatures. Three different layers of soil and mulch will be
tested at a northern site to create a cultural practice to growing sugarcane in colder
Fertilizer recommendations for energycane production in areas outside the traditional cane-
growing region of the United States may differ from sugarcane requirements. Fertility
management at the plot scale will be investigated using five rates of nitrogen, including
none, minimal, middle range and high rate.
Supplying a quality feedstock consistently is critical to bioenergy sustainability. In
collaboration with the feedstock development objectives, energycane varieties currently in
the pipeline will be evaluated. Sufficient seed cane will be planted in 2011 to allow for
repeated harvests at monthly intervals beginning in September 2012 and ending in January
Four energycane varieties will be planted as whole stalks or billets at the Sugar
Research Station in St. Gabriel, La. Energycane seed will be cut either by chopper
harvester or by a soldier harvester and planted mechanically. These stalks will be measured
for population, heights, wet yield and moisture content.
At the Sugar Research Station, a set of six sweet sorghum hybrids, two each from early-,
medium- and late-maturity groups, will be planted in a split-plot design with three
replications; whole plots will be by planting date and sub-plots will be by hybrid.
At the Rice Research Station, field trail treatments will include two tillage systems
(conventional and no-till) and two fertilization practices (no fertilization and maintenance
fertilization). Each treatment will be replicated four times.
Optimized legume nitrogen utilization strategy will be determined for sweet sorghum
production systems. Cold-season legume crops will be established in fall at two
locations (Macon Ridge and Southeast research stations). Sweet sorghum will be planted in
each subsequent spring using both conventional and no-till for seedbed preparation.
Incidence and severity of diseases will be visually assessed intermittently in experiments
established to address tasks 1-5 at four locations.
In each sweet sorghum and energy cane plot, above- and below-ground biomass will be
Research at the University of Wisconsin-Madison will involve life cycle assessment (LCS)
studies associated with sustainability assessment of the production of second-generation
biofuels and biorenewable chemicals from energycane and sweet sorghum feedstocks.
