Forages are the foundation of livestock nutritional requirements; forage diversification and fertiliser are intensification options that can increase productivity. A sample of 316 and 313 smallholder farmers were surveyed in eastern midlands and central highlands of Kenya, respectively, to establish the types of forages cultivated and the factors that influence fertiliser adoption in Napier grass ( Cenchrus purpureus Schumach.) production. Independent t -tests were applied to compare the effect of continuous variables on social economic and institutional characteristics between adopters and non-adopters on fertiliser and area allocated to different forages. Chi-square tests were used to compare nominal variables for the proportion of farmers growing different forages, criteria they consider in selection of suitable forages, and social economic and institutional characteristics of adopters and non-adopters of fertiliser. Binary logistic regression was used to determine factors that influence fertiliser adoption. The study revealed that forage diversification was low with Napier grass being the only forage cultivated by most farmers (~90%). Urochloa ( Urochloa spp ), Rhodes grass ( Chloris gayana Kunth.) and Guinea grass ( Megathyrsus maximus Jaq.) were cultivated by less than 11% of farmers. The fertiliser adoption rate was high (77%) and was influenced by gender of household head, membership of groups, access to extension services and labour. Future research should focus on promoting of forage diversification and investigate quantity and fertiliser application regimes in order to enable development of appropriate advisory services.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"33 3","pages":"245-256"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41278022","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 study examines factors controlling farmers’ decision to adapt to climate change and evaluate the impact of such decisions on farm output. Using primary data from 138 rice farming households in Ndop-Cameroon, we employ the probit model with endogenous switching regression to investigate the impact of the farmers’ adaptation decisions on output. The results indicate that access to credits, other incomes, farmers’ age, extension services and farmer groupings form key factors that significantly affects farmers’ decision to adapt to climate change. Strategic implementation of adaptive measures, significantly increased average output of adapters by 49%. Building resilience against climate change and ensuring food security, therefore requires stakeholders to take into account existing management strategies and the underlying factors influencing these. This study suggests the crucial need for institutional advancement and policy changes towards credit accessibility for rice farmers. More local farmers’ associations should be created and extension services improved to enhance effective adaptation and farmers’ vulnerability.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"122 1","pages":"231-243"},"PeriodicalIF":0.0,"publicationDate":"2021-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49014976","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}

Three hundred poults from two genotypes (160 local and 140 exotic turkeys) were raised for twenty weeks. Bodyweight (BW), rectal temperature (RT), pulse rate (PR) and respiratory rate (RR) were measured weekly. Blood samples were collected from each turkey before and after inoculations at week 8 and 13 for serum antibody detection using enzyme-linked immunosorbent assay. Genotype had a significant (p < 0.05) effect on all the parameters measured. Exotic turkey had higher weight than local while sexual dimorphism was in favour of toms despite challenge with Salmonella typhimurium . The RT was significantly higher (p < 0.05) in exotic turkeys except at week 2, 6 and 8. In like manner, PR was higher (p < 0.05) in exotic turkey except at week 4 (204.28±2.48 beats/minutes) and 8 (216.98±1.46 beats/minutes) where it was higher in local turkey. RR also followed the same trend while HSI was higher (p < 0.05) in week 2 (1.53±0.06 breaths/minutes) and 14 (1.17±0.07 breaths/minutes) in exotic turkeys. Local turkeys had higher (p < 0.05) antibodies against Salmonella organisms before and after inoculation while the hens of both genotypes had higher (p < 0.05) antibody titres at the 7 th day after inoculations. The present results seemed not to be convincing enough to suggest differences in tolerance/susceptibility to Salmonella infection and therefore the two genotypes may be equally adapted.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"122 1","pages":"219-230"},"PeriodicalIF":0.0,"publicationDate":"2021-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48330776","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}

In the case of the Mbororo minority community of Northwest Region of Cameroon, these threats are exacerbated by already existing problems of marginalisation. This study assesses agricultural risks in the global context of food distribution and gross domestic product that also poses a specific threat to the food system of the Mbororo people. The study aims to (1) assess the types of agricultural risk encountered by the Mbororo community, (2) examine the likelihood and severity of these risks, and (3) appraise local risk management strategies adopted to minimise the negative impacts of these risks on the food system. The study makes use of a mixed method approach for data collection. Findings have revealed animal diseases (83 %), absence of infrastructures (83.6 %), price variation (76.6 %), and drought (75.8 %) as the most encountered risks in the case study area. Especially, drought, political insecurity, pest and rodent, farmer-grazer conflict, and crop and animal diseases emerged as the highest intensity or priority risks with the need for urgent management strategies intervention. Agricultural risk assessment is frequently used to assess and prioritize risks but has hardly been used in the case of minority groups such as the Mbororo community of Northwest Cameroon.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"122 1","pages":"207-217"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49305337","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}

A person is deemed to be time poor if (s)he works more than 10.5 hours per day, the internationally accepted threshold. Using the time allocation domain of the Abbreviated Women’s Empowerment in Agriculture Index, the study found that on the average, rural women and men spent about 10.3 hours and 8 hours, respectively, on work activities on a daily basis. Work activities for women were found to be diverse, spreading across reproductive and productive domains largely farming, own business e. g. trading, cooking and domestic work, while for men, work activities centred on productive economic activities, dominated by farming. Using a Probit regression model, the study found experience in agriculture and adoption of television to reduce the likelihood of time poverty among rural men. Surprisingly, participation in empowerment projects was found to increase the likelihood of time poverty among rural women. In conclusion, empowerment programmes should be expanded to address the non-material aspects of human well-being. Hence, the study recommends a gender-sensitive approach to intervention programmes in agriculture and adoption of a broader definition of empowerment which not only focus on expanding access to markets and increasing income but enhances control over time. This is more important for women who are already under the double burden of paid and unpaid domestic work.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"122 1","pages":"193-205"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45891138","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}

Commercial interest in the species has grown in recent years. The major obstacle of seed-based propagation of baobab is its inherent seed dormancy. Therefore, in this study the effects of different mechanical seed scarification methods on seed germination parameters and seedling development of A. digitata were tested. The results show that mechanical scarification had a significant effect on germination and emergence dynamics of A. digitata . The highest total emergence percentage with 61.7% was achieved by scarifying the seeds with a saw on the hilum side. Cotyledon damage due to mechanical scarification occurred in all treatments. Proportions of damage categories depended significantly on treatment. The largest proportion of undamaged cotyledons was with 63.6% achieved by scarifying the seeds with a saw on the hilum side. This precise technique may be suitable for mass propagation of baobab in a rural setting but the effects of scarification methods on seedling emergence should be further investigated.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"122 1","pages":"183-192"},"PeriodicalIF":0.0,"publicationDate":"2021-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44341615","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 study was conducted to identify the factors influencing households' decision to join ACs in Central Bhutan. A cross-sectional survey was conducted to collect data from 384 households (192 AC members and 192 non-AC members). Trained enumerators collected data in June and July 2018 using structured questionnaires. The binary logistic regression showed that households with older heads of household, being literate, having more family labour, more land under cultivation, owning farm machinery, being further away from a market, and having access to credit increased the likelihood of households joining ACs. Conversely, households earning off-farm income and locating far from the Renewable Natural Resources Centres decreased the likelihood of becoming member of ACs. Additionally, the gender of the head of a household and the number of cattle owned by a household showed no significant influence. As this paper is the first to empirically investigate the determinants of households’ membership in ACs in Bhutan, the findings have some important policy implications. The government should continue to provide in-depth awareness to farmers on concepts and benefits of ACs in retaining existing members and recruiting new members.","PeriodicalId":54889,"journal":{"name":"Journal of Agriculture and Rural Development in the Tropics and Subtropics","volume":"122 1","pages":"173-181"},"PeriodicalIF":0.0,"publicationDate":"2021-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45915984","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}
