Seventy-one core actors (service providers, producers, processors and marketers) in the poultry value chain were randomly selected for the study. Data were collected using a structured interview schedule. Data were analysed using percentages, charts and mean scores. Results show that the mean number of males and females employed by the producers on a full-time basis was two persons each for the 2010, 2011, 2013, 2014, 2015 & 2016 production seasons. In 2010, the mean monthly payments for males and females employed by the producers on a full-time basis were ₦8,171.43 and ₦8,466.67, respectively. The majority (62.5%) of the producers were poor. Service providers’ perceived benefit of the poultry value chain includes employment creation (=2.00) while processors indicated sustainability of agricultural projects (=3.00). The poultry value chain approach of CADP was sensitive in their employment structure and was beneficial in terms of poverty eradication through job creation. The government should support the actors in the poultry value chain financially specifically the producers through the provision of credit facilities such as loans to bring about positive change in their wealth status.","PeriodicalId":43669,"journal":{"name":"Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140511229","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}

Data were collected using structured questionnaires and analyzed with the Statistical Package for Social Sciences (SPSS) version 27. Frequency and percentage were used to gain insight into the distribution of their socio-economic characteristics. A multinomial logistic regression model was used to determine the influence of farming experience and knowledge in selecting climate change resilience strategies among female agripreneurs. The study revealed that female agripreneurs with a vast farming experience of more than ten years were well-capacitated in adopting biological, chemical, and environmental resilient strategies. Furthermore, it was noted that all groups of agripreneurs had incorporated environmentally resilient strategies for their reliability, cost-friendliness, familiarity, and workload. The study also revealed that female agripreneurs who opted for technological and biological knew pest and disease control and pest scouting, respectively. The study recommends that farmers with vast farming experience be climate change resilience champions within their regions, as their experience is instrumental.","PeriodicalId":43669,"journal":{"name":"Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2024-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140511189","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 results showed that agricultural extension agents (85.0%) and fellow farmers or cooperatives (61.7%) are the prominent sources of farm-related information on AYB production. The result of the regression analysis showed that sex, household size, primary occupation, farm size and extension contacts were significant and positively influenced AYB production while education was significant but negatively influenced AYB production. Challenges against AYB production include inadequate finance (78.3%), high cost of labour (72.5%), low yield of AYB per hectare (68.3%), pest and diseases (65.8%), inadequacy of AYB for planting (60.8%) and old age of most farmers (53.3%) among others. The use of insecticides (81.7%), pesticides (40.8%) and use of traps (29.2%) constitute the highest pest and disease control measures used by the farmers. The study concludes that socioeconomic factors play significant roles in the AYB output of farmers. Efforts should be made to increase the capacity of the farmers through education and training to improve their efficiency and productivity.","PeriodicalId":43669,"journal":{"name":"Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135931859","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}

Data for the study was collected using a questionnaire and in-depth interviews while analysis of data was carried out using, mean, percentages and the Binary Logit regression model. Results showed that 98% of the researchers were involved in research uptake activities. Publication of journal articles (76%), convening training workshops (60%) and organizing seminars (59%) were the major research uptake activities conducted by agriculture researchers in the State. Insufficient funds (x=3.68), lack of basic facilities (x=3.54) and poor synergy between researchers and policymakers (x =3.48) were major constraints faced by agriculture researchers in conducting research uptake activities. Agriculture researchers’ socioeconomic characteristics were not significant determinants of agriculture researchers’ level of involvement in research uptake activities in the study area.

Results showed that the least used climate-smart agriculture (CSA) practices were agroforestry (27.7%), water harvesting practices (25.1%), construction and use of irrigation facilities (14.1%) and land reclamation practices (16.2%). The majority (72.3%) of farmers got einformation on climate-smart agriculture from the radio, while 8.9% and 12.6% got it from internet websites and social media respectively. E-information that was less accessed by the farmers was information on zero tillage (x=2.33), and minimum tillage. There was a weak, positive monotonic relationship (ys= 0.029) between farmers’ use of climate-smart agriculture practices and access to e-information. Reliable and timely climate-smart agriculture information targeting tillage, cropping, and water harvesting and use should be developed by extension service providers, uploaded and broadcasted via traditional electronic media and other non-e-sources for easy access and use by farmers.","PeriodicalId":43669,"journal":{"name":"Journal of Agricultural Extension","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135931611","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}
