It was conducted in Oyo State, Nigeria using a multistage sampling procedure to select the 48 respondents from whom data were collected using a structured questionnaire. Percentage was used to analyse the socioeconomic and enterprise characteristics of the respondents, while gross margin analysis was used to determine the profitability of the enterprise. A linear regression model was used to ascertain the drivers of enterprise profitability among respondents. Findings revealed that over half (54.4%) of the fabricators produced processing equipment, while fewer (28.2%) produced farm tools. Most of the fabricators operated with a mean workshop space of 1.3 m2. The gross margin analysis showed a total revenue of N95,302,900 exceeding the total cost of production (N20,374,205), indicating (N74,928,695) profitability of their enterprise with an N3.68 return on investment per Naira. Fabrication being a secondary occupation (β=0.340), and business registration with the Corporate Affairs Commission (β=0.473) significantly influenced profitability among the respondents. This study recommends regulating the fabrication sector through policies, ensuring that fabricators register their outfits with designated statutory bodies to significantly enhance the standardization of outputs and increase the units of production, hence, improving the profitability of the enterprise.","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":"140510714","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 findings showed Insecurity, high farmer-to-extension agent ratio and inadequate training facilities as challenging factors that affect extension service delivery. The study concluded that extension service delivery was highly ineffective because of the low extension-farmer ratioand low motivation among the agents. It is recommended that the government employ more extension agents to reduce the possible imbalance in extension service delivery to farmers.","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":"140511036","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 analysed using percentages, mean statistics, standard deviation and Chi-square.  The most adopted rice variety was CK 90 (86.6%).  Factors influencing the adoption of improved rice varieties were market channels (84.9%), membership of associations (91.7%) and contact with extension personnel (85.5%).  Most (97.2%) rice farmers knew about growing improved rice varieties. Most (66.1%) of the respondents had a favourable attitude towards growing improved rice variety but faced constraints like insufficient loan ( = 2.89), weed infestation ( = 2.37), storage losses ( = 2.19) and low extension activities ( = 2.11). The adoption characteristics of respondents were good (88.3%) with economic characteristics having the highest mean ( =2.71). Educational qualification was significantly related (χ2 =1.149) to the adoption characteristics of improved variety.

Data were analysed using percentage and mean statistics. Results revealed that the average age of female and male respondents was about 44 and 41 years, respectively. Men, women and youths played complementary roles in various operations in ABB production. Men (37.5%, 32.8%, 32.8% and 13.5%) and youths (32.8%, 33.9%, 34.9% and 10.9%) dominated heavy labour operations like land clearing, ploughing, harrowing and fertilizer application, respectively, while women (60.4%, 53.1%, 59.9%, 63% and 61.5%) dominated other operations like planting, harvesting, processing, storage and marketing respectively.  Therefore, all genders are involved in ABB production in the area. Efforts should be made to target different genders in ABB production. This can be done through the dissemination of improved technologies in the various production operations. This will ensure that roles are not neglected, thereby enhancing the production of African black beans.","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":"140510825","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 proportionate sampling procedure was used to select 122 agro-dealers for the study. A survey questionnaire and focus group discussion were used to collect data. The data were analysed using percentages, ranked discrepancy scores (RDS) and the Wilcoxon signed rank test. The Wilcoxon signed rank test at a 5% level of significance indicated the need for training in good agronomic practices (z= -7.679), planning of demonstration plots (z= -4.434), evaluation of trials (z= -3.818), financial management (z= -3.765), and business planning (z= -2.412). However, the need for training in recording and reporting (z= -0.395), and input ordering and distribution (z= -0.440) were not significant. Agro-dealers need training to develop their knowledge and technical capacity on the agro-inputs they sell, in order to provide up-to-date and authentic information about these products.

Data were collected from the subscribers of the agricultural content accounts of Saudi Arabia on social media using an online survey with the help of a structured questionnaire and a convenient sampling methodology. Both descriptive statistics and Pearson correlation analysis were run to analyse the data. The majority (81%) of the respondents preferred agricultural information in the form of videos, followed by photos (75%). Moreover, a moderate to high impact was reported by the respondents on their various agricultural skills. Trust in social media had a significant negative correlation with respondents’ perceived impact on their crop production skills. The respondents’ preferences for a particular type of information had a significant positive correlation with the perceived impact of social media on their crop production skills.
