Taxus baccata is a native species to the Caspian forests and is considered as the identification of these forests by some resources. The aim of this study was to understand the ecological characteristics of T. baccata in order to find suitable areas for its plantation in the Pone Aram preserve of Golestan province. Therefore, Multi-Criteria Evaluation (MCE) methods based on Analytical Hierarchy...

Traditionally, plantation sector in India has been regarded as a source of foreign exchange. Hence the system of innovation and production evolved over the years mainly at the instance of the state has been geared to enhance its international competitiveness. Though the role of plantation sector in the export basket of India declined over the years, the paper argues that the present role of pla...

Flowering and vegetative growth were assessed in 19 half-sib families of Alnus rubra Bong. planted in a replicated field trial near Olympia, Washington, USA. The trial consisted of three square spacings (0.5, 1.0 and 2.0 m), two irrigation regimes (low and high), and two fertilization treatments (0 and 300 kg P ha(-1)). Male and female flowers were surveyed in all plots for all families at plan...

This paper examines changes in carbon (C) pools associated with land-use, synthesizing data from two experiments dealing with different aspects of tree plantation establishment in Central Panamá. First, we analysed soil profiles in a grazed pasture and an adjacent 5-year-old teak (Tectona grandis) plantation. There were small differences in soil C mass in the top 10 cm of the pasture and the pl...

Plantation agriculture is more than 400 years old and contributes to the regional and national economies in many tropical countries. This paper reviews some of the main environmental issues related to plantation agriculture with perennial crops, including soil erosion, soil fertility decline, pollution, carbon sequestration and biodiversity. Soil erosion and soil fertility decline are of concer...

Four different forest restoration modes (Acacia mangium plantation, mixed-native species plantation, conifer plantation and Eucalyptus plantation) were evaluated using Energy System Theory and the emergy synthesis method. In addition, the eco-exergies of the four forest restoration modes were calculated, and combined with emergy and empower density to explore the restoration and selforganizatio...

This paper examines idiosyncrasies of tea plantation culture and politics in relation to Sri Lankan national and popular cultural typologies, with special reference to female tea plantation workers. Tea production in Sri Lanka is heavily based on manual labour, and it is the largest industry that provides accommodation for employees and their families. In this paper, it is argued that politico-...

(ABSTRACT) Scholarship on slave families has focused on the nuclear family unit as the primary socializing institution among slaves. Such a paradigm ignores the extended family, which was the primary form of family organization among peoples in western and central Africa. By exploring slave trade data, I argue that 85% of slave imports to Virginia in the 18 th century were from only four region...

Weed identification in vegetable plantation is more challenging than crop weed due to their random plant spacing. So far, little work has been found on identifying weeds plantation. Traditional methods of used be mainly focused directly; however, there a large variation species. This paper proposes new method contrary way, which combines deep learning and image processing technology. Firstly, t...
