“…This work was based on material from a SRIC field plantation located at the "Julio Hirschhorn" Experimental Station, Faculty of Agricultural and Forest Sciences, National University of La Plata, in Los Hornos, Buenos Aires, Argentina (34°59'09'' S; 57°59'42'' W). The plantation took place between August and September of 2012 (Doffo et al, 2017b). 24 experimental units of 56 plants were arranged in a three-block, split-splitplot layout.…”

“…The lower heating value (cal/g) was calculated from the upper heating value according to Owens and Cooley (2013); and for the hydrogen content (%), the published values for Salix wood were used (Waliszewska et al, 2006). The energetic yield for each treatment (Gj/ha) was estimated from the lower heating value and the biomass data for this season published in Doffo et al (2017b) The statistical analysis was carried out using the INFOSTAT package (InfoStat, 2008). The normal distribution of the variables was checked with the Kolmogorov-Smirnov test and the homogeneity of variances with the Levene test.…”

EFFECTS OF IRRIGATION, PLANTATION DENSITY AND clonal composition ON WOODY BIOMASS QUALITY FOR BIOENERGY IN A SHORT ROTATION CULTURE SYSTEM WITH WILLOWS (Salix spp.)

et al. 2018

A short rotation intensive system with willows was analyzed with the following aims: a - to determine the effects of irrigation, genotype and plantation density on wood anatomy, wood density, moisture content, lower heating value, total ash content and energy accumulated in the woody biomass; b - to explore the relationships between anatomical and physical wood properties and the parameters determining their quality as a biofuel. A complete factorial experiment was set up, with three factors and two levels for each factor. The factors were: irrigation, plantation density and clone (genotype). The clones were Salix matsudana Koidz. x Salix alba L. ‘Barrett 13-44 INTA´ (B) and Salix alba L. ‘Yaguareté INTA - CIEF´ (Y). 46 stools of 1 m long were sampled, on which the following determinations were carried out: vessel diameter and frequency, fiber wall thickness and area, wood density, moisture content, ash content and heating values. Clone B had higher wood density than clone Y (0.406 vs. 0.395 g/cm3) and lower moisture content (47.11 vs. 50.53 %). The plantation density did not affect any of the variables analyzed. Irrigation increased the energy yield to 393.2 Gj/ha, compared to 309.15 Gj/ha without irrigation. A system with clone B planted at a lower density (13,000 plants/ha) and under irrigation has the best advantage as an energetic crop over the other alternatives evaluated in this work.
