The review revealed that technology adoption, including vaccine technology adoption, is gendered, with women tending to adopt less than men, especially in terms of consumer associated drivers. CBPP vaccine adoption can be enhanced through one or a combination of up to four strategies, which include: price reduction and provision of subsidies by government and philanthropic projects especially in times of enhanced and unpredicted demand; convincing, evidence-based, demonstration of benefits of vaccination over its alternatives using methods such as return on investment for every dollar used; gender sensitive advocacy strategies and messages; and carrying out human and livestock vaccination campaigns, simultaneously, in pastoral communities living in marginal areas.","PeriodicalId":11421,"journal":{"name":"East African Agricultural and Forestry Journal","volume":"104 1","pages":"221 - 238"},"PeriodicalIF":0.0,"publicationDate":"2019-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83009729","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}

Assessment of soil quality will always help farmers to apply correct fertilisers in correct proportions to their soil. This will definitely help them achieve maximum yield with minimum expenditure. Not only that, they can conserve their environment. Assessment tools for indexing soil quality at various scales were pursued to show the multiple functions that soils provide as the foundation for sustainable land management. Newly developed soil quality index called Heber soil quality index (HSQI) is widely used to identify and differentiate the various types of soils. In the current investigation, the soil samples were taken in the rice and sugarcane fields from, at least fifteen places of the Thiruvarur district (9.28° N, 79.3 °E) and were categorised as excellent, good or bad for cultivation of the rice and sugarcane on the basis values of Heber soil quality index (HSQI). The HSQI values of all samples ranged from 73.34 to 81.04, which reveals that the quality of soils studied in this investigation is good for the cultivation of rice and sugarcane. The index was found to be time saving and cost effective method of assessing the fertile nature of the soil for the effective cultivation of rice and sugarcane. Soil quality assessment in the light of HSQI is intended to provide a better understanding of the soil resources measures to be taken, to improve the quality of soil system for the better yield of any crop in general and rice and sugarcane in particular processes.","PeriodicalId":11421,"journal":{"name":"East African Agricultural and Forestry Journal","volume":"9 1","pages":"206 - 220"},"PeriodicalIF":0.0,"publicationDate":"2019-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73008733","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, the yield of the crop is constrained by low soil fertility and poor agronomic practices. Therefore, the field experiment was conducted at the main campus of Haramaya University and at Hirna Research substation during the 2015 main cropping season. The objective of the experiments was to elucidate the effect of seed tuber planting depth and nitrogen fertiliser rate on yield-related traits and yield of the crop. The treatments consisted of four seed tuber planting depths (5, 10, 15 and 20 cm) and five rates of nitrogen (0, 46, 92, 138 and 184 kg N ha−1). The experiment was laid out as a randomised complete block design with three replications. The results of the experiment at both locations revealed that the main effect of nitrogen application rate influenced total dry weight, unmarketable tuber yield, the percentage of small-sized and medium-sized tubers. Nitrogen rate and seed tuber planting depth also interacted to influence unmarketable tuber yield, the percentage of medium and large-sized tubers produced, and tuber starch content. The main effects of seed tuber planting depth significantly influenced total dry biomass, unmarketable tuber yield, total tuber yield, marketable tuber yield, the percentage of small-sized tubers produced and tuber starch content. Increasing seed tuber planting depth generally enhanced the aforementioned parameters. However, for most parameters, the highest values were obtained already at the seed tuber planting depth of 10 cm. The optimum total and marketable tuber yields of 26.93 t ha−1 and 26 t ha−1 for Haramaya and 34.57 t ha−1 and 32.65 t ha−1 for Hirna were obtained in response to planting seed tubers at the depth of 10 cm.","PeriodicalId":11421,"journal":{"name":"East African Agricultural and Forestry Journal","volume":"IM-30 1","pages":"101 - 118"},"PeriodicalIF":0.0,"publicationDate":"2019-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84740112","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 current study was therefore conducted as a cross-sectional survey covering a sample size of 282 smallholder farmers in the Coast Region to generate information on economics of woodlots. Farmers were sampled using stratified random sampling procedures and a questionnaire with open and closed ended questions was applied to collect growth data, costs of production and benefits. We investigated the economics of woodlots on smallholder farms by estimating the nett present value and annual equivalent values of various woodlot enterprise opportunities. Results show that Casuarina equisetifolia is the most profitable woodlot enterprise. Production of C. equisetifolia is economically viable and has better financial returns than any other woodlot enterprise. Profitability of woodlots on smallholdings depends on level of integration into existing farming systems, market outlets where products are sold and level of value addition. Highest profitability is achieved when woodlots are intercropped with maize at initial stages of establishment, and selling their processed products through local market centres; one acre of C. equisetifolia gives an average nett present value of KES 856 117, which translates to a discounted annual profit margin of KES 153 361 over a seven-year rotation period. The Melia volkensii and Gmelina arborea woodlots are equally profitable with average nett present values of KES 583 486 and KES 514 301, respectively leading to conclusion that woodlots are economically viable on smallholdings in the Coast Region. It was accordingly recommended that smallholder farmers in the Coast Region be encouraged to integrate woodlots of high value trees in their farming systems to help diversify and optimise their farm incomes.","PeriodicalId":11421,"journal":{"name":"East African Agricultural and Forestry Journal","volume":"14 1","pages":"1 - 12"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81928609","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}
