- Germination and conservation of the germinative power of Griffonia
simplicifolia (DC.) Baill: African plant of therapeutic and fodder value
Abstract: Griffonia simplicifolia is a Caesalpiniaceae legume that grows from Liberia to the Democratic Republic of Congo. The leaves are widely used in Togo for their nutritional value. On the other hand it is most known for the richness in 5-Hydroxy-L-tryptophan (L-5-HTP) of its seeds. Farmers collect significant amounts of fodder directly from Togos forest formations, resulting in a scarcity of thi...

- Suitability of sand amended with carbonized rice husks and goat manure as
a growing medium
Abstract: A laboratory experiment was conducted at Rwanda Agriculture and Animal Resources Development Board (RAB). The study determined a suitable and alternative growing medium to peat moss as an unaffordable medium to Rwandan farmers and soil-based growing media which produce low quality transplants. Growing media were formulated from sand (S) amended with carbonized rice husks (CRH) and goat manur...

- Seed germination, storability and moisture sorption isotherms of the
endangered African rosewood (Pterocarpus erinaceus)
Abstract: African rosewood (Pterocarpus erinaceus) is an endemic, highly exploited and endangered tree species in arid and semi-arid zones of West Africa. Identifying optimum conditions for seed propagation and storage is critical for its conservation. This study assessed the effects of four pretreatments on seed germination and seedling vigour. Varying temperature, duration and packaging on storage d...

- Regulated deficit irrigation (RDI) under citrus species production: A
review
Abstract: Regulated deficit irrigation (RDI) is considered among the best water-saving techniques for supplementing Regulated water to fully achieve the water needs of the plant while maximizing water productivity with little or no substantial decrease in final produce compared to the conventional forms of irrigating crops. The aim of this paper is to review existing RDI approaches used in citrus prod...

- Pre-sowing treatments for enhancing germination of Guibortia coleosperma
and Amblygonocarpus andongensis seeds from Kazuma Forest Reserve, Botswana
Abstract: The effect of seed presowing treatment on Guibortia coleosperma and Amblygonocarpus andongensis was investigated. Seeds of both species were subjected to four experiments, containing 10 levels of presowing treatments: mechanical scarification, soaking in concentrated sulphuric acid (for 15, 30, 45 and 60 min), immersion in boiling water (for 1, 3 and 5 min), and soaking in boiling water (and...

- Influence of different light intensity on early growth of Jatropha curcas
L. seedlings
Abstract: This study investigated the influence of different light intensities on the early growth of Jatropha curcas seedlings. Forty (40) seedlings were randomly selected from the germinated seedlings in the nursery and arrayed under four different treatments (0, 20, 40 and 60% light intensity). The amount of light being received by each of the seedlings was regulated, using constructed wooden box c...

- Evaluation of selected multipurpose tree species and moisture conservation
structures for degraded dryland rehabilitation in Dugda Dawa District,
Southern Ethiopia
Abstract: Land degradation affecting the livelihoods of people living in dryland areas, particularly the Sub-Saharan Africa countries like Ethiopia. Degraded land rehabilitation in dryland is a challenging task due to moisture limitation. This study was conducted to evaluate the effects of soil and water conservation structures on growth of planted tree and rehabilitation of indigenous plant species i...

- Physiological quality of African eggplant seeds as influenced by natural
fermentation and drying methods
Abstract: Seed extraction and drying methods are important procedures employed after harvesting fruits of African eggplant as these methods affect the seed quality. This study sought to evaluate the seed physiological quality of two cultivars of African eggplant subjected to various durations of natural fermentation and different drying methods. In the first study, fruits were fermented for 0, 6, 12, ...

- The lupeol content in Machaerium species by HPLC-APCI-MS/MS and the
allelopathic action
Abstract: The use of extracts from plants and/or allelopathic compounds from natural products can minimize the use of pesticides in agriculture. This is a chemical study of Machaerium eriocarpum branch extract and the evaluation of the allelopathic potential of Machaerium hirtum (Vell.) Stellfed and M. eriocarpum Benth (Fabaceae) leaves and branches extracts. The triterpene lupeol was isolated from th...

- A photographic method for measurement of tree height: More accurate and
simpler than other methods'
Abstract: In the photographic method, a photo is taken of the tree with an object of known reference height beside it. An inexpensive cell phone camera can be used. The tree height is calculated by using a ruler to measure the tree height and reference height on the photo. Previously, this method was thought to be accurate only if the distance to the camera was many times the tree height. However, if ...
