Assessment of Floral Composition for the Restoration of Mount Bamboutos, Western Highlands of Cameroon

Louis Nkembi, Njukeng Jetro Nkengafac, Ngulefack Ernest Forghab
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...

Climate Change and Carbon Sequestration among Smallholder Farmers in Uganda: An Introduction and Review of Literature

Hellen Abbo Owasa
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...

Natural Regeneration of Indigenous Species under Plantation Forests of Mahoganis (Swietenia macrophylla and Swietenia xaubrevilleana): The Case of Martinique

Philippe Joseph, Kévine Baillard, Jean-Philippe Claude, Yelji Abati, Séverine Ely-Marius, Stéphane Sophie, Yanis Jean-Francois, Jean-Emile Simphor, Peguy Major
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 ...

Quality Control of Medicinal Herbs—Has Good Agricultural Practice (GAP) Helped?

Ping-Chung Leung, King-Fai Cheng
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high-quality medicinal plant production in China, has experienced negative results and is no longer recommended, it has been replaced by HACCP management system.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...

Mangrove Dynamics near Douala International Airport (Cameroon Coastal)

Fulbert Rodrigue Zogning Lontsi, Paul Tchawa, Joseph Youta Happy
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...

Two New Species of Edible Berries, One in Gaultheria L. and Other in Vaccinium L. (Ericaceae) from Costa Rica and Panama

Alexander Francisco Rojas-Alvarado, Pablo Munnoz-Cambronero
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.,...

Serpocaulon orosiense, a New Hybrid of Serpocaulon (Polypodiaceae) from Costa Rica

Alexander Francisco Rojas-Alvarado, Lucía Barrantes-Calvo
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 ...

Yield and Quality of Rainfed Cotton (Gossypium hirsutum L.) in Response to Nitrogen Rates under Different Plant Available Water Capacity Sites in Central Dry Zone of Myanmar

Thu Zar Win, Kyaw Ngwe, Swe Swe Mar, Aye Aye Khaing
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...

Effects of Nitrogen Rates on Cotton under Different Plant Available Water Capacity Sites in Pyawbwe, Central Dry Zone of Myanmar

Thu Zar Win, Aye Aye Than, Kyaw Ngwe, Aye Aye Khaing
Soil water content and nutrient availability are two main factors of limiting plant growth and productivity in an uncertain rainfall area likes central dry zone of Myanmar (CDZ). The aim of this research was to observe the effects of nitrogen (N) rates on rainfed cotton (Gossypium hirsutum L.) under different plant available water capacity (PAWC) sites. The field experiments were conducted during post-monsoon season 2019 at two sites, Pawaingyoe and Kokkokhahla, of Pyawbwe Township having differ...

Improvement of the Nutritional and Technological Quality of Rice by Steaming

Rasoazanakolona Voahanginirina, Rakotonjanahary Xavier
The parboiling rice is rarely practiced technique in Madagascar, despite its many advantages. In this study, we have shown interests from the operations of our local varieties (Rojomena, red varygasy, Marisika, FOFIFA 159 “Mahasoa” (useful), FOFIFA 161 “Mahefa” (competent), FOFIFA 172) and identification of qualities offered: there was a variation in the optimal steaming time according to varieties; there was also a technological improving (as yield in whole grains, and as quick cooking food), n...
