1 Energycane: First Year Brian Baldwin, Herbaceous Feedstocks Meeting San Antonio, Texas 22 February 2010

2 Energycane -Hybrid of sugarcane and wild cane -Bred for high fiber, high biomass -Tolerance to cold weather -Fermentable sugars

3 Concept Energycane – Cellulose for bioethanol/biomass High yields and perennial Limitations of sugarcane’s abilities in the “North” Sugarcane infrastructure in place – Advantage of sucrose Can be fermented if harvestable Sugary bagasse is subject to enhanced fermentation as a precursor to cellulose SSF Capture-able with slow pyrolysis

4 Common Energycane Germplasm Germplasm Line*Pedigree Ho F 1 (Wild Cane x Sugarcane) Ho F 1 (Wild Cane x Sugarcane) Ho BC 1 with Sugarcane Ho BC 1 with Wild Cane Ho BC 1 with Wild Cane *from USDA-ARS-SRU, Houma, LA

5 Base Field Dimensions Plot = 10 m x 3 rows (6m) – Sacrifice row (Brix) – Harvest 2 rows Base Rep = 10m x 30m Base Test = 132m x 30m – (or any combination) inclusion of other genotypes

6 Spring Emergence data – date and rating (shoots/plot) Date of 50% emergence and soil temp Data during growing season – Height, bi-weekly – Brix monthly from sacrifice row

7 July Stalk counts and diameter

8 Fall 2009 Harvest Data EOS – Each location needs to fix that time Stalk count and diameter Final height Rating after first hard frost (differences?) Final Brix – want a 50 ml sap sample, freeze Fresh harvest weight – Sap yield – Stalk moist weight – Stalk dry weight – Stalk samples for fiber analysis Starkville MS; Nov 2007

9 Fall/Winter Harvest (other two rows) Moisture Southern locations Harvest and weigh

23 Issues/Major Factors LocationIssue/Major FactorStatus Waimanalo, HILegislation Heat treatment of seed cane Overturned, 2009 Slow growth Beaumont, TXHurricane Rita spawned tornadoesSeed cane unavailable, 1 year behind College Station, TX DroughtLower yield, but on track Starkville, MSExcessive rainLive with it

24 Obstacles to Data Collection El Niño – Rain, rain, rain, rain, rain, and still rain – Starkville ended 84.5” (54” normal) – Same at: Tifton, Athens, St. Gabriel The weight of biomass – Energycane harvested at 60-70% moisture – A dry weight of 3 T/A is actually 4.2 T/A – Most sites harvest by hand

30 Summary Findings Brix affected by rain Brix affected by genotype Spring onset of growth different – Early onset in genotypes closer to sugarcane can lead to higher yields at the southern locations – Early onset of genotypes closer to wild cane are not good for maximum growth in the “North” (spring frost)

31 Summary Findings, cont’d Yield varies by genotype Location matters, with Tifton, GA toping locations – Well-drained soils, with excellent rainfall Ho seems best adapted to all locations tested.

33 Energycane Drawbacks Energycane – Of tropical origin Not photoperiodically senescing – Wet harvest – Removal of nutrients Limitations of sugarcane’s abilities in the “North” – Advantage of sucrose Limited accumulation, especially with excess rain Sugar and fiber are inversely proportional – Associative nitrogen fixation
