However, the national productivity is very low as compared to the potential of the crop. One of the main reason for low productivity is low soil fertility. Hence, a field experiment was conducted from 2016-2018 with 9 combination of nitrogen, phosphorous and sulfur fertilizers arranged in randomized complete block design with three replications to assess response of potato to these rates. The application 110-19.74-50.8 kgâˆ™ha-1 N2/S2 /P2O5 fertilizer delayed days to flowering and maturity by 8 and 11 days at Darark and 10 and 14 days at Dabat. However, it increased plant height and number of stems per plant, which may positively contribute to increased photosynthetic area. The application of these fertilizers advanced marketable tuber yield by 153% and the total tuber yield by 86.6% relative to unfertilized plants. Furthermore, the partial budget analysis data showed that the highest net benefit and marginal rate of return (4453.6%) was obtained from 110-19.74-50.8 kg ha-1. Therefore, the current study results is indicative that potato can grow well and provide better yield at Dabat, Dabark and similar agro ecology by using 110-19.74-50.8 kg ha-1 N2/S2 /P2O5, respectively. \u0000 \u0000 Key words: Fertilizer, marginal rate of return, marketable tuber, yield.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128958529","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, these socio-economic roles and the associated challenges have not been studied in Bibugn District of East Gojjam, Ethiopia. Therefore, this study was conducted to assess the socio-economic importance of highland bamboo and the associated challenges for its expansion. For this study, four rural sub-districts were selected purposively. Both semi-structured questionnaires and key informant interviews were used for data collection. Statistical Package for Social Science (SPSS version 20) and excel 2016 were employed for the data analysis. The result indicated that there were 82 respondents who have got their own bamboo lots while the remaining 53 respondents did not have their own bamboo lots. The study also revealed that about 149 ha of land was covered by highland bamboo culm under the four sub-districts of the district. Highland bamboo in the study area has been used frequently for house construction, flooring, basket making, source of income and for other household utensils. Among challenges and constrains of highland bamboo expansion in the study area, the most frequent ones were; less market demand followed by land scarcity and eucalyptus expansion competing with bamboo expansion. Statistically, there were no significant difference (p>0.05) among sub-districts on the challenges on highland bamboo expansion. For enhancing the socio-economic significance of Bamboo plant in the area, addressing the challenges through awareness creation, proper harvesting, processing, value addition and diversification of products is recommended. \u0000 \u0000 Key words: Yushania alpina, bamboo, challenges, expansion, socio-economic importance.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123274052","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}

AMF inoculation did not have statistically significant effect on RGR-CD and RGR-H but conspecific inoculum resulted in significantly lower RGR-H of C. africana at the 2nd month, indicating the probability of species specific effect of AMF inoculation. \u0000 \u0000 Key words: Arbuscular mycorrhizal fungi (AMF), Chancho, forest restoration, relative growth rate (RGR), seedlings survival.","PeriodicalId":267383,"journal":{"name":"Journal of Horticulture and Forestry","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133812934","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 objective of this study is to evaluate morphological diversity of tamarind germplasm from Eastern parts of Kenya. Tamarind germplasms were collected from Kitui, Mwingi, Masinga, Embu and Kibwezi and then characterized using morphological descriptors based on seed, fruit and stem.

The experiment was laid out as a randomized complete block design (RCBD) in a factorial arrangement and replicated three times.
