DocumentPopulus deltoides windbreak: its robust status in wheat production and soil nutrients in Indo-gangetic plains of northern India
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Agroforestry systems (AFS) with fast-growing woody crops such as poplar (Populus deltoides) are increasingly integrated into agricultural land because it is considered as a sustainable agricultural practice that combines primary production with other ecosystem services (ES). To optimize the efficiency of AFS, the suggestion is to develop well modified tree-crop integration by limiting competition for resources and capitalize on the coactions. However, yield data of various wheat varieties in AFS are inadequate, in particular for Populus deltoides windbreak at a age of four and five year old plantation. Here we focused on winter wheat varieties (WH-1105, HD-2967 and HD-943) during two consecutive years (2017-2019) comprising delimited by a row of deciduous poplar trees in East-West and North-South directions (East-West tree line divide farmlands into two aspects i.e. Northern and Southern and North-South tree line divide into Eastern and western aspect). While effects on crop produce were limited for all wheat varieties with the increasing distance from tree line, however, five years old poplar planted on field bunds exhibited significant reduction up to 3 m in grain yield of wheat from tree line for all the wheat varieties. The highest available soil N (210.5 kg ha–1), P (15.3 kg ha–1) and K (280.2 kg ha–1) were recorded near tree line at a distance of 3 m. To optimize the provisioning service of poplar windbreak AFS, the cultivation of highly shade tolerant wheat variety HD-2967 may be advisable over other wheat varieties towards the end of the rotation of poplar windbreak AFS.

ArticleBitternut hickory (Carya cordiformis(Wangenh) K. Koch), a successful non-native tree species in the north-west of Romania
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The most abundant and most uniformly distributed of all the hickories (Carya spp.), growing throughout the eastern United States, bitternut hickory was introduced to Europe after 1689. It was used as ornamental species especially in parks and dendrological gardens as well as forest species in some European countries (e.g. Austria, Belgium, France, Germany).
In Romania, it was planted exclusively in parks and dendrological gardens, with the exception of Sacueni Forest District. In this area, the first three individuals of bitternut hickory were planted in 1900, reaching nowadays breast diameters between 72.3 cm and 79.2 cm and heights over 25 m. Using seeds collected from these trees and seedlings produced in the local nursery, the species has expanded after 1957 and the total area of thirteen stands including bitternut hickory reaches nowadays 39.21 ha, with some interesting characteristics:
- it is found in monocultures as well as mixed stands (proportion between 10 percent and 90 percent) with different broadleaved tree species, both native (pedunculate oak Quercus robur L., small-leaved linden Tilia cordata L., sycamore Acer pseudoplatanus L.) and exotic (black walnut Juglans nigra L., northern red oak Quercus rubra L., pin oak Quercus palustris Muenchh., and black cherry Prunus serotina Ehrh.);
- bitternut hickory grew quickly in youth and reached mean diameters between 18 cm (25-30 years of age) and 32 cm (60 years) and mean heights between 16 m (25-30 years of age) and 25 m (60 years). These dimensions are similar to or even bigger than the associated species, both native and exotic;
- the species regenerates easily by seed and its seedlings have a higher shade tolerance than most of its associates, even though bitternut hickory is considered as intolerant of shade;
- it is a good self-pruner and epicormic branching is not a problem;
- it has never been affected by any damaging agent and is wind-firm, owing to its dense root system, with a pronounced taproot. Keywords: Sustainable forest management, Adaptive and integrated management ID: 3471954 -
ArticleIncreasing land cover by promoting agroforestry-based tree planting to sustain community livelihood under various social forestry schemes in Indonesia
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The high challenges and expectations in the management of Indonesian Tropical Forests to achieve the community welfare, forest sustainability and sustainable development goals, demands proper management in optimizing the use of forest resources to meet the high dependence of community needs on the forest. The pressure on forests is reflected in the deforestation that occurs as an indication of the various dependencies of the community on forests to meet their daily needs. In this regard, Agroforestry is a potential silvicultural recipe as a solution to restore degraded land and forest that can gain balance ecological, economic and social benefits. This paper aims to provide information on plant growth performance and survival rate in the establishment of agroforestry plot for a total 34 hectares in three schemes of Social Forestry in Indonesia, namely Paru Village Forest (VF)–West Sumatra, Cempaka Forestry Partnership (FP)–Lampung, Tuar Tana Community Forestry (CF)– East Nusa Tenggara, in collaboration between Forestry and Environment Research, Development and Innovation Agency with the Asian Forest Cooperation Organization (AFoCO). It was conducted by planting 26 plant sp Intensive Artificial Regeneration with planting distance of 8x8 m and 5x5 m depend on plant species. The collected data covered for survival rate and height measurement. Growth Percentage was observed at ages 1, 6, 12 and 18 months after plan participation which looks high in maintaining their crops while survival rate in Tuar Tana CF was low enough only 43,2% due to the drough in this semi-arid region which affect the plant growth, eventhough the farmers have high effort in maintaining their crops.
