BackgroundA higher vegetable intake plays an important role in promoting general health and well-being, but there is a dearth of data on the independent effect of vegetable intake on health-related quality of life (HR-QoL). This study contributes to evidence on the independent effect of vegetable consumption on HR-QoL among women in fertile age.MethodsA cross-sectional study of a sample of rural women in fertile age (15–49 years, n = 187), randomly selected from 6 rural communities in the Tolon and Savelugu Districts, Northern Region of Ghana. Vegetable consumption in the past month was assessed with a 27-item semi-quantitative food frequency questionnaire; self-reported HR-QoL with the Short Form Health Survey (SF-36); nutritional status with anthropometry; household food security with the household hunger scale (HHS) and demographic and socio-economic related covariates with a pre-tested semi-structured questionnaire using face-face interviews. Generalised Linear Models were fitted to assess adjusted mean scores and their 95% confidence intervals (95% CIs) by terciles of vegetable intake and vegetable variety score (VVS) for the HR-QoL, its physical health (PH) and mental health (MH) domains and the SF-36 subscales.ResultsThe mean vegetable intake of the women was 324.6 ± 196.1 g/day. The mean scores of the HR-QoL, PH and MH were 69.5 ± 13.6, 72.6 ± 17.4 and 66.4 ± 12.6 respectively. The alpha Cronbach measure of reliability for the HR-QoL, PH and MH were 0.78, 0.75 and 0.62 respectively. After adjusting for potential confounders such as age, body-mass-index (BMI), parity, educational status, occupation, marital status, HHS and household asset index, we observed an increasing trend across terciles of vegetable intake in the past month for the HR-QoL (P-trend = 0.0003), PH (P-trend = 0.02), MH (P-trend = 0.001) as well as the physical functioning (P-trend = 0.01), role-physical (P-trend <.0001), and role emotional (P-trend <.0001) domains of the SF-36. The multivariate model of the results also showed a significant increasing trend in the adjusted mean scores of the HR-QoL (P-trend = 0.04), MH (P-trend = 0.001) as well as 4 subscales of the SF-36 [role-physical (P-trend = 0.02), role-emotional (P-trend = 0.05), emotional well-being (P-trend = 0.002) and vitality (P-trend <.0001)] across terciles of the VVS.ConclusionThe results of the present study suggest a potential beneficial role of high vegetable intake and consumption of more varied vegetables on HR-QoL. Further research is needed to determine the mechanisms driving these influences.Electronic supplementary materialThe online version of this article (10.1186/s12889-018-5845-3) contains supplementary material, which is available to authorized users.

The study was conducted in organic and conventional crop farms in the West Mamprusi District of the Northern Region of Ghana. The key issue the study sought to determine was whether there are productivity differences among organic and conventional crop farms and what factors account for these differences. The results indeed revealed that there are productivity differences among organic and conventional crop farms. However, both had negative total factor productivity growth, largely accounted for by a negative technical change over the period considered. The technical efficiency change, however, was positive for both but much higher for organic farms than conventional farms. More importantly, the study revealed that the type of agriculture practiced by farmers is not the most critical problem confronting farmers as indicated by the negative total productivity growth for both. Major constraints confronting farmers that need to be addressed include better organization on the farmers' front, improved access to extension and improved access to farm inputs. These challenges notwithstanding, the study revealed that organic agriculture has the potential, in the long run, to achieve much more progress in total factor productivity, compared to conventional agriculture, if the right conditions exist for its uptake and optimal application.

The production of traditional African vegetables is an age-old tradition among the people of the northern region of Ghana. However, the knowledge base of traditional African vegetable production remains local due to a lack of research and policy support. Therefore, the adoption of improved technology among traditional vegetable farmers is generally low and impedes efforts to promote widespread cultivation, consumption and even commercialisation. This study aims at clarifying potential factors that determine the adoption of technologies by traditional African vegetable farmers in the northern region of Ghana. One hundred and five (105) respondents in five communities and across two administrative districts in the northern region were selected for an in-depth survey using a combination of quantitative and qualitative data collection methods. In addition, a logit regression was used to determine the effect of various factors on technology adoption by farmers. Among the factors, the educational level of a farmer, access to credit, farm size, experience in farming and access to extension support were found to be important factors affecting the decision of traditional African vegetable farmers to adopt improved technology. The results of this study can help enhance the effectiveness of policy re-orientation towards a more effective commercialisation of traditional African vegetables in Ghana and elsewhere.

PurposeThis paper examines the performance of smallholder rice farms established using improved planting technologies – broadcasting, dibbling and transplanting – under different production systems – rain-fed and irrigation – in Ghana.Design/methodology/approachUsing recent cross-sectional data of 200 smallholder rice farmers from the upper east region of Ghana, this study employed multinomial logit model and descriptive and inferential statistics for the analysis.FindingsThe results revealed that rice production under irrigation system contributes significantly to increasing farm productivity and profitability. Rice farmers who adopted dibbling and transplanting technologies under both irrigation and rain-fed production system obtained higher productivity and profitability than those who used broadcasting technology. Adoption of improved rice planting technologies by smallholder farmers is significantly influenced by education, farm size, improved rice varieties, sales outlets, hired labour and percentage of paddy sold.Research limitations/implicationsThe sample size is relatively small, even though findings are still very important in terms of policy formulation for improved smallholder farm performance in a developing country like Ghana.Practical implicationsThis study calls for collaborative efforts by government, donor agencies and NGOs to establish irrigation facilities and/or expand existing ones, increase sensitization and dissemination of improved planting technologies, as well as intensify the input subsidy programme in Ghana.Originality/valueTo the best of the authors knowledge, this is the first study that focuses on farmers' choice of rice planting technologies under irrigation and rain-fed production systems, and how these technologies impact on smallholder farm performance in Ghana.

The study was conducted in Northern Ghana comprising of the Northern, Upper East and Upper West regions. The objective of the study was to analyse maize-based rain-fed vegetable production systems with a view to explore their potential to contribute to food and income security for rural households. A combination of qualitative and quantitative data collection methods were employed during the study. Questionnaires were employed to collect quantitative data, through semi-structured interviews on socio-cultural and economic dimensions of vegetable production including household characteristics, consumer perspectives and the economics of production and consumption of vegetables. The targeted respondents were households and consumers. Rain-fed cereal-based vegetable production is a key component of the traditional farming system in Northern Ghana and served as the main source of vegetables for rural households. The results showed that all households in the study area integrated vegetables with maize mainly for home consumption. Only a few households cultivated vegetables with the sole purpose of income.
