“…Among the plants that have been investigated in terms of their potential to produce biomass count the poplar, the short-rotation willow, and the maritime pine [14,15]. There is a constant quest for the most productive energetic plants, the ones that have a fast rhythm of growth, and those that have an intense production per surface unit [16,17].…”

“…Under the conditions of areas that have a productivity that ranges from middle to low, the culture of poplar can bring after the first cycle an average overall biomass production, which does not include the component parts, of about 35 to 40 t/ha in 4 years, and of 55 to 60 t/ha after 5 years of vegetation, for a density of plantation of 2667 pieces per ha. The last season of vegetation brings an additional amount of the total biomass of 35%, which leads, after 5 years of vegetation, to a production of about 11 to 12 t/ha/year [15]. The biomass of the branches represents about 18 to 20% of the total biomass, regardless of the vegetation year in which the harvest is completed.…”

Wood is used as a raw material in various industries, including the production of furniture, which puts pressure on the exploitation of the forests and the continuous reduction of their surfaces, with undesirable effects on the environment. The paper provides a way of sustainably manufacturing furniture by replacing wood with composite materials based on natural fibers obtained from fast-growing renewable crops (hemp, willow, flax, etc.) and at the same time a method of assessing the forest areas which can be saved from cutting. The method’s algorithm is based on the estimation of forest area that ensures the annual consumption of wood for the production of furniture, both in the conventional production of furniture and in the unconventional one, where part of the products is made of composites. The agricultural areas required to be cultivated with technical plants to provide the natural fibers necessary for the wood replacement composite were also determined. The case study, based on the data of an upholstered furniture company, shows that replacing only part of the wood for the production of furniture can save about 3000 hectares of beech forests per year and the necessary plant fibers can be obtained from a surface area about 10 to 100 times smaller.

“…Dispozitivul experimental a fost alcătuit din două blocuri, unul parcurs cu lucrări de întreţinere (TI), celălalt neparcurs (TN). În fiecare bloc experimental s-au plantat câte trei rânduri de sade din trei clone de plop (AF2, AF8 și Pannonia), care s-au dovedit prin experimente anterioare (Dănilă 2015, Dănilă et al 2016) a fi cele mai productive. Întreg experimentul a fost mărginit de o parte şi de alta a suprafeței de câte o zonă tampon, sub forma unor benzi de plopi din clona AF8.…”

Intensive hybrid poplar crops can produce an important biomass if adequate measures of management are being used. During the last years, there is a constant involvement on refining poplar cultivation technology, regarding installation, maintenance and harvesting, in order to obtain superior production at lower costs. The present study has analysed the effect of an experimental maintaining treatment (TI) (harrowing and weed control) on poplar crops' biomass yields. The results were obtained after two vegetation seasons and compared with the results recorded in a control plot where no maintaining practices (TN) were used. The experimental crop was set up in the spring of 2013, in the vicinity of Dornești site (Suceava County). Three hybrid poplar clones were tested (AF2, AF8 and Pannonia) in each plot, and there were installed by long rods, using the 3.0 x 1.5 m spacing. The biomass was assessed for all the harvested individuals and every tree component using the gravimetric method. The experimental maintaining treatment (TI) led to important differences between the two plots. The total biomass in TI plot was nearly eight-times superior to the biomass obtained in the control plot. All the three clones reacted significantly to the experimental treatment TI, even though minor differences were observed between the clones' productivity. The effect of TI treatment was also substantial to the biomass' structure on tree components. It is considered that the massive biomass increase was encouraged by a consistent shift of biomass proportion in the favour of the crown proportion (branches biomass), rather than subterranean elements. Keywords poplar energy plantations, short rotation crops, biomass yield, effects of disc harrowing, weed control.

In Romania, the productivity of the new clones of hybrid poplar has not been tested in recent years. This case study aims to fill a gap on the productivity map of the new poplar clones, estimating, by biomass measurements, the productivity of two clones (AF2 and AF8) with different planting densities (from 1333 trees·ha−1 to 2667 trees·ha−1). The short-rotation woody crops (SRWCs) were established in homogeneous conditions, in North-East (NE) Romania and the northern part of Suceava County. Using a specifically developed method, biomass production was estimated using destructive methods, with 190 poplar trees being harvested, measured, and weighed to compute the accumulated biomass for each growing season The biomass production of the crops with 1667 trees·ha−1 planting density highlighted significant differences in productivity in favour of the AF2 clone after five growing seasons. The crops shared similar annual growth patterns, and the stem biomass represents approximately 73–80% of the total biomass of the trees. The second research question concerning planting density influence on productivity showed fluctuations of biomass accumulations at different planting densities (1333 trees ha−1, 1667 trees ha−1 and 2667 trees ha−1) for a 5-year rotation. The outcomes emphasized the influence of the annual weather conditions—primarily the rainfall in May–June—on poplar growth, showing that productivity also depends on the genotype, density and biotic disturbances.
