ArticleThe preservation of natural forests through the establishment of industrial wood production plantations via the new, fast growing Robinia pseudoacacia ‘Turbo Obelisk’ varieties and new cultivation technologies
XV World Forestry Congress, 2-6 May 2022

No results found.After decades of research and development, Silvanus Forestry Ltd. and HungaroPlant Ltd. have successfully propagated the Robinia pseudoacacia ‘Turbo Obelisk’ variety group and developed the necessary cultivation technologies, specifically for intensive industrial wood production plantations. In comparison to the Hungarian and traditional black locust varieties and cultivation technology, industrial wood production plantations established with our variety group and using our cultivation technologies can produce twice as much timber yield and industrial timber yield, considering 15-year rotation periods. These parameters are comparable with the performance of the widespread Eucalyptus and Pinus plantations in the subtropics. Our varieties and cultivation technologies, however, are also usable in subtropical, temperate, as well as tropical climates. The outstanding yields achieved by the ‘Turbo Obelisk’ varieties and the extremely high industrial wood output can provide a significant contribution to the conservation and maintenance of natural ecosystems, whilst the CO2 sequestration per unit area per time is also several times that of natural forests. A particular advantage to emphasize is long term carbon sequestration due to the high percentage of industrial wood yield. Increasing the exceptional tolerance of black locust against drought, pollution and low-quality soils, our varieties are exceptionally suitable for the utilization of marginal agricultural areas, the agricultural utilization of which would otherwise create an economical loss. This can also significantly increase the advancement of less developed regions. In addition to plantation cultivation, it also provides a cost-effective solution for the establishment of protective forest belts, road-side plantings, quicksand fixation and soil renovation. Delicious honey production is also a possible revenue stream. The global exploitation of the research findings has begun, having already successfully established test plantations in China, India, and Pakistan, as well as in several European countries.

ArticleMelia dubia Cav.: A tree for industrial revolution and economic gains to farmers
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Melia dubia Cav., member of family Meliaceae, found upto 1800 amsl in India and thrives well under variety of soils and climatic conditions. The short rotation indigenous tree meets raw material requirements of timber, veneer, ply and paper industries. Forest Research Institute, Dehradun, India has released ten cultivars for commercial cultivation with excellent bole form and average productivity of 34.57 m3ha-1 yr-1. These varieties are not only potentially contributing in supply of raw materials to different industries but also pivotally reducing foreign exchange. Though evaluated germplasm consisted exceptional variability for pulping parameters, few genotypes were found utmost suitable for paper manufacturing with pulp yield upto 55.32 %.The general purpose plywood (interior grade) was found to meet IS specification, and Progeny No. FRI/MD/104 performed with maximum modulus of rupture and modulus of elasticity along and across the grains, followed by Progeny No. FRI/MD/028, FRI/MD/075 and FRI/MD/076. Additionally, ply made from wood of Progeny No. FRI/MD/028 and FRI/MD/076 performed suitably in dry and wet state glue shear strength. The ply manufactured from this wood fetches handsome price in the market with low maintenance expenditure. Economically, plantations of the species are most suited to growers and when planted in rows along the field bunds about 60 trees can be planted per acre generating an income of about Rs. 2 Lakh in sixth year of planting. On the other hand, planting 300 to 400 trees per acre in blocks give a minimum profit of Rs. 1 lakh per year from an acre. Under good maintenance and controlled irrigation from sixth year onwards, trees with about 100 cm GBH and clear bole of 5 to 7 meters can fetch upto Rs. 4000 to Rs. 5000 per tree depending on soil depth and quality. Furthermore, total carbon stock and CO2 sequestration potential of improved varieties calculated substantially higher to the tune of 17.90 and 82.80 t.ha-1 yr-1.

Book (stand-alone)Poplars and Willows: Trees for Society and the Environment 2014
Also available in:
No results found.Taxonomy and classification of the Salicaceae are addressed in an authoritative manner, with descriptions of all important individual species, but recognizing the differences in philosophy that still exist in these topics. Natural ecosystems are described. Genetic resources of poplars and willows are covered comprehensively, including selection, tree improvement and conservation, as well as the latest developments in genomics. Cultivation of poplars in plantations for industrial uses was the cor e of previous volumes and continues to be given prominent treatment, with information also on willow cultivation. A major 21st century topic included is the environmental applications of poplars and willows in phytoremediation, rehabilitation of landscapes and for carbon sequestration, biodiversity and urban amenity, among other uses (McCutcheon and Schnoor, 2003). The most important diseases of poplars and willows are described, as well as strategies for their control. Insects and other animal pests of poplars and willows are treated similarly. Wood properties and utilization of poplars and willows for traditional, as well as emerging, new products are presented. Markets, trends and outlook for wood products worldwide are analysed, considering poplars in relation to tree species in general. The benefits of poplars and willows for sustainable land use and rural livelihoods, including agroforestry, food security, poverty alleviation and shelter, particularly in developing countries, are highlighted.
