(Annonaceae) is a multipurpose shrub species, but threatened in Burkina Faso. Therefore, understanding its natural regeneration is a challenge for the sustainable management of the species resources. Our study examines the regeneration potentials of A. senegalensis across two phytogeographic zones. The structure of Weibull showed that the distribution of the regeneration individuals based on height classes was inverse J-shaped in the two phytogeographic zones. The structure reveals a relative predominance of individuals in small size classes. A log-linear adjustment test of Weibull’s confirmed the observed distribution and Weibull distribution were not conformed (p<0.0001). A generalized linear model (GLM) and an ANOVA showed that the density of the natural regeneration of A. senegalensis was significantly higher in the south-sudanian zone. The density of the regeneration stratum 1 was 2.46 times higher in the north-sudanian than in the south-sudanian zone. The Green Index (GI) confirmed that the spatial distribution of regeneration individuals was random (GI=0). Annona senegalensis reproduces mainly by seed germination. Annona senegalensis faces difficult natural regeneration, worsened in the north-sudanian by the climate pejoration and a stronger anthropogenic pressure. The study suggests assisted natural regeneration, which should contribute to better conservation of the species.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129750686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vegetative propagation has been proposed to overcome some of the reproductive biology challenges in the species. The study was to determine the influence of stem size on sprouting and survival of stem cuttings of African teak. The experiment was conducted at Egerton University, Njoro, Kenya. The propagation materials were collected from healthy mother trees from the Coast and Western regions of Kenya. A Randomized Complete Block Design was used. The cutting lengths were 3, 6 and 9 cm. The planting medium was composed of river sand. Data were collected monthly on the number and height of sprouts and the cutting survival at the end of 150 days. Data were then subjected to analysis of variance (ANOVA) using GENSTAT 15th Edition. Separation of means was performed using the SED. The results showed that the cutting length had a significant effect on the number of sprouts, F=43.45, df=2, p= 0.001 and height of sprouts produced, F=48.25, df=2, p=0.001. None of the cuttings obtained 50% of survival though the highest survival percentage obtained was 48.1% from cuttings with 9 cm length. The survival of cuttings obtained from 6 cm length reached 41.27% while 3 cm length attained 31.75%. It was concluded that cutting length positively influences the sprouting of cuttings; hence longer cutting should be selected for propagation. Further studies should take into account the optimum cutting length and the factors which influence the shoot formations and cutting survival including diseases prevention and age of cuttings.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114877759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its dense canopy and expected allelopathic effect make it very difficult to survive for many of the associated crops grown under it. Therefore, current study was undertaken with the main objective to investigate the allelopathic and shading effects of mango on the germination and early growth performance of food crops and medicinal plants. Leaf extract of mango was tested to find out its inhibitory or stimulatory effect on maize, pea nut and haricot bean with varying concentration of extracts (0, 10, 15 and 20%) at lab and pot study. Results of the study witnessed the inhibitory effects of its extract on germination and early growth performance of cereal and pulse crops for most of the parameters studied. However, severity of inhibition was more pronounced with increase in concentration of the extract. Similarly, shading intensity of mango tree on two Hibiscus varieties WG-H Jamaica and WG-S were tested at a certain canopy distances (1/3rd, 1/2 and at tree periphery) from the bole of mango tree. Results reflect the increase in growth performance of both the varieties with increase in canopy distances from the bole of the tree probably due to better transmission of light. It is recommended that Hibiscus varieties should not be planted at the very closest distance from the mango trees stem due to allelopathic and shading effects, respectively.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130094933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is because despite various benefits provided by the resource, it receives little attention in terms of policy formulation and planning to enhance adequate investments and allocation of funds. Therefore, with increasing demand rate of 3.3% over 27% of woodfuel in SSA will continue being produced unsustainably using inefficient technologies; leading to a deforestation and degradation rate of over 3.5 million ha per year. The situation is worse in some countries like Kenya where over 40% of biomass energy especially is obtained from arid and semi-arid lands (ASALs) characterized by less than 4% productivity rate due to poor regeneration and vegetation growth rates. Thus there is need to implement various strategies including adoption of improved and efficient production and utilization technologies, increase on-farm tree planting and enhanced tree out-grower systems, enactment and proper implementation of biomass energy policies, establishment of reliable biomass energy database, and recognition of biomass energy benefits to the society. These will foster integration of biomass energy into planning programmes to enhance investments in the sector and reduce biomass energy resource overexploitation.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128864470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transportation of harvested roots to the south has consequently resulted to decay, shrinkage, loss of roots due to high temperature and long distant travels, high cost of produce etc. The objective was to find out the variety and tillage method that will enhance the production of carrots in Southeast Nigeria and the appropriate poultry manure rates for production. Two Carrot varieties (Touchon mega and Kurado) were evaluated under field experiment and were grown under three poultry manure (PM) rates (0,5,10 t ha -1 ) and two tillage methods (Ridge and Bed) to assess their effects on the growth and yield of carrot roots. Roots were harvested at the 90th day after planting and data were collected on seedling emergence, root weight, leaf weight, whole plant biomass, percentage marketable yield, and total marketable yield. The result showed that poultry manure significantly (p<0.05) enhanced higher yields. The ridge tillage method gave a higher marketable yield than the Bed type. Kurado variety had the highest percent marketable yield though there were no significant (p>0.05) differences between the two varieties. The tillage method and poultry manure influenced the growth and yield of carrot roots suggesting that the appropriate tillage method and poultry manure rate will enhance production in the environment. From the results of the experiment, it could be concluded that for the production of carrots in the environment Kurado variety is recommended due to its high yielding capacity while Ridge tillage method is recommended for farmers in the area due to its efficient use and ability to support root penetration; 10 t ha -1 manure rate was found to be most economical manure rate.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126669498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 Togo's forest formations, resulting in a scarcity of this species, which is classed as non-timber forest products. Massive anthropization, in combination with the low germinative potential of G. simplicifolia seeds, poses a threat to the species' survival and availability. It is critical to promote and disseminate G. simplicifolia 's culture in order to help save the species, which is presently critically endangered. It is in this perspective that the study of germination and conservation of the germination capacity of G. simplicifolia seeds was conducted. The ecotype being studied was that of Lomé, which was harvested on the campus of the University of Lomé. Light, integuments, time, and storage temperature were all factors considered when studying germination. To optimize the germination speed, it is essential to remove the seed coat and germinate the seeds with light in the greenhouse as in vitro . The cold helps to preserve the germination capacity of seeds, which deteriorates quickly in warm environments.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115108029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
