Heritiera fomes Buch-Ham and Excoecaria agallocha L. are two major mangroves of the Sundarban mangrove forest. Among them, Heritiera fomes Buch-Ham is a less salt-tolerant species than E. agallocha, which is a salt-tolerant species but not extremely salt-tolerant. The flowering and fruiting behavior, seed germination, and seedling survival rate of Heritiera fomes Buch-Ham and Excoecaria agallocha L. were studied in three different saline zones viz. Oligo...

Early field growth performances of four Eucalyptus urophylla × Eucalyptus grandis clones (18 - 147, 18 - 170, 18 - 228 and 18 - 50) produced by two different techniques of propagation by rooted cuttings were compared. The results obtained showed that height growth did not differ significantly up to 18 months between plants derived from indicate rooted cuttings produced from coppicing stumps and those issued from intensively managed container-grown stock plants, the four clones comb...

The study was aimed at assessing the floral composition of the Mount Bamboutos landscape. A literature search was used to gather information about plants found in Mount Bamboutos. For field data collection, forest patches found along a proposed two-line transect of 12 km each were explored for the collection and identification of plant specimens. A total of 332 species of plants (herbs, shrubs, trees, lianas, climbers and epiphytes) were identified belonging to 89 families. Out of these, the Rub...

In Uganda, sorghum constitutes the second most widely grown cereal according to the latest statistics from the country’s statistics body, the Uganda Bureau of Statistics. This notwithstanding, there has been, in the context of Uganda, very little research and published literature on its potential to sequester carbon. There is no sufficient data on the exact levels of carbon sequestered by this sorghum/legume intercropping system, which is widespread as a technology within Uganda’s smallholder so...

In many geographic areas influenced by tropical and temperate climates, natural forest ecosystems have been destroyed in favour of plantations of allochthonous trees which are economically profitable for different aspects of the timber industry. Some of these mature plantations degrade the soils and inhibit natural regeneration of the local flora; others, due to the physical constraints they impose, can contribute to the installation and the development of autochthonous taxa. The plantations of ...

Although GAP, as the overall regulatory practice of safe and high-quality medicinal plant production in China, has experienced negative results and is no longer recommended, it has been replaced by HACCP management system. HACCP system focuses on specific projects of quality and safety assurance, from agricultural production to complex plant requirements, and then to specific technical considerations. GAP plantation can never meet the huge actual demand, but HACCP system can still be carefully c...

The purpose of this research is to assess the evolution of the mangrove swamp near Douala international airport over the past five decades. The study is based on the collection and processing of data (bibliographic, aerial photographs respectively from 1974, 2003 and 2009; Landsat Multispectral scanner satellite images from 1974, Quickbird from 2003 and Geo Eye from 2012 and 2020). The study is also based on observations and surveys (with 37 semi-interviews, 03 focus groups and the administratio...

Recent studies on the flora of paramos in Costa Rica, reveal two new endemic taxa described here as Gaultheria paramicola A. Rojas and Vaccinium reptans A. Rojas, both known only from Costa Rica and Panama. The first new species have been confused with Pernettya prostrata (Cav.) DC. (=Gaultheria myrsinoides Kunth), however due to its mucronate leaves without visible secondary veins and white to red fruits it is more related to G. mucronata (L. f.) Hook. & Arn.,...

Four hybrids between Serpocaulon species have been described, one of them S. × sessilipinnum was the only known hybrid between two different clades proposed by Smith et al. In this work, a new hybrid S. × orosiense is described, being the second known hybrid between clades: 1) Serpocaulon loriceum and 2) S. fraxinifolium. The detailed study of the intermediate morphology of the characters of the new taxon and their progenitors were made by ...

The aim of this research was to explore the optimum nitrogen (N) fertilizer rate for yield and quality of rainfed cotton under respective PAWC. A two-year field experiment was conducted in 2019 and 2020 during post-monsoon season at two sites, Pawaingyoe and Kokkokhahla, having different PAWC. Each year at both sites, six levels of N rate (T1 = 0, T2 = 60, T3 = 90, T4 = 120, T5 = 150 and T6 = 180 kg N ha^-1) were laid out in randomized complete block design with four replications and c...
