Farmers’ adoption of RE in agriculture can lead to substantial reductions in Greenhouse gases (GHG) emissions as well as providing alternative income sources for farmers, and reliable energy supplies for farms and households. Policies can facilitate, support, or encourage farmers’ adoption of RE. However, it is not clear what policies currently exist which facilitate or promote the adoption of RE technologies in Ghanaian agriculture. This paper aims to identify policies in Ghana that can facilitate the adoption of RE in agricultural production. A policy review was conducted to identify such policies, evaluate their potential impact on RE adoption, and suggest paths to enhance RE adoption by farmers. These policies are focused on two aspects: 1) promoting solar energy and 2) the conversion of agricultural waste to energy. Noting limitations including the underdevelopment of the RE sector and the lack of a central policy to promote RE utilization in Ghanaian agriculture, the review suggests that policymakers need to fully implement provisions of the Renewable Energy Act-(832) (2011) through the application of, for example, policy levers such as subsidies, tax exemptions, financing, and training potential end-users in the agricultural community.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121244252","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}

We employed semi-structured questionnaire and focus group discussions to collect data from the respondents. The data were analysed descriptively and presented in percentages and frequency counts. The data were further subjected to Chisquare, Pearson’s Product Moment Correlation, t-test, multiple linear regression analysis and Explorative Factor Analysis (EFA). The findings revealed that the majority of men (99.7%) and women farmers (96.8%) perceived to adapt to climate change. Men (= 2.29) relative to women (= 2.33) used more on-farm adaptation strategies. The strongest determinant of usage of climate change adaptation strategies by men farmers was climate change adaptation barriers (t = 5.13, p < 0.01), while for women farmers, climate change experience (t = 7.42, p < 0.01) was the strongest determinant. The promotion of gender-sensitive approaches to climate change adaptation that cater for the needs of men and women farmers is highly essential to enhance adaptation among them.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127103652","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}

Results showed that the appropriate level of benzyl adenine required for inducing more stolon and sucker production was 1.5 mgL-1. Optimum levels of coconut water required was 15 ml. A multiplication ratio of 1:15 and 1:16 suckers and stolons for CO and BA treatments, respectively was achieved. Planting the suckers in three cycles in a year, a potential of 3,375 or 4,096 stolons and suckers could be generated when the taro is treated with either CO or BA respectively. Benzyl adenine or coconut water can be used to induce many stolons and suckers to generate more planting materials. Farmers who cannot obtain commercially made benzyl adenine can use coconut water for the process.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126797705","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}

On the other hand, gender-blind agricultural innovation delivery strategies impede short- and long-term impact among adopters. Due to a disregard for gender differences, many agricultural programs fall short of their objective. Recent studies in Nigeria are yet to adequately capture the gender differentials in the economic implication of BCVs adoption. This study, therefore, investigates the gender differentials in the economic implication of BCVs’ adoption among farmers in Oyo State, Nigeria. A multistage sampling procedure was used to select a total of 180 respondents for the study. Data collected were analyzed using descriptive statistics and budgetary techniques. Descriptive statistics revealed a significant difference between the socio-economic characteristics of male and female cassava farmers. The results suggested that BCVs’ production is profitable and can serve as a panacea for the economic improvement of households. Study findings thus concluded that the adoption of BCVs is economically beneficial to cassava farmers and thus recommended that concerted efforts are made to ensure all farmers adopt BCVs for planting. The study proposes an integration of gender-responsive strategies to further enhance the delivery of BCVs in Nigeria.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129755213","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}

Twenty four male rabbit bucks, about 10 months old were randomly allotted to four treatments in a completely randomized design. Blood samples were collected at day 21 and day 42 from the bucks and processed for total protein, glucose, haematocrit, haemoglobin, erythrocytes, leukocytes,and leukocyte differential count determination. Serum total protein was significantly (p < 0.05) higher in rabbits administered 0.3 mgkg-1 and 0.4 mgkg-1 at day 21 than those fed 0.2 mgkg-1. However, Glucose, alanine aminotransferase, spartate aminotransferase, and alkaline phosphatase were not significantly influenced by L-SeMet administration at both days 21 and 42. Blood urea was significantly (p < 0.05) lower in bucks administered 0.4 mgkg-1 L-SeMet comparedto the control. Creatinine and sodium levels in the bucks were also not significantly influenced by L-SeMet. This suggested that exogenous supplementation of L-SeMet did not have adverse effect on the physiological processes of the rabbit bucks. Increased serum total protein observed in the experimental animals could be attributed to L-SeMet administration to the rabbit bucks which probably enhanced dietary protein utilization and/or protein synthesis.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130269434","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}

Specifically, it seeks to measure the motivation behind farm records keeping, the nature of records kept, the benefits derived from the activity and how demographic and socio-economic characteristics of farmers influence the practice. Using a multi-stage random selection procedure, 120 pineapple farmers selected from 25 pineapple growing communities in the Municipality were interviewed using structured interview schedules. The study showed that records keeping was common among the pineapple farmers interviewed with the farmers keeping at least six (6) farm records. The chi-square test showed that farm records keeping depended on educational level, years of experience in pineapple farming and farm size. Besides, records keeping was informed primarily by the desire to make productivity projections and promote effective agribusiness management. The study makes a strong case for sustained communication, education and awareness creation on the practice to engender good agribusiness outcomes.","PeriodicalId":174273,"journal":{"name":"Ghana journal of agricultural science","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124119332","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}

Results revealed the awareness level of improved yam varieties at 50% and low adoption rate of improved yam varieties at about 6%. Factors found to significantly influence adoption were awareness, education, distance to farm and extension access.
