1. {"_":"Performance prediction and stability of maize hybrids in contrasting environments.","i":["Striga"]}
PMID:日期:2025-12Maize yield and production are significantly hampered by , causing up to 100 % yield loss under severe infestation in Africa. This research sought to: (i) assess whether extra-early maize hybrids' yield and plant aspect performance under -free conditions could respectively predict yield and host damage performance in -infested environment; (ii) identify -resistant/tolerant biofortified hybrid maize and; (iii) identify maize hybrid with stable yield and tolerance/resistance to stress. To achieve the above, 150 maize hybrids (obtained from the hybridization of 30 lines using the factorial mating design II) and six checks, were examined in -free and -infested environments at different locations in Nigeria over two years. The regression coefficients and R obtained when plant aspect and grain yield across -free conditions were used to predict host damage and grain yield across infestation and vice versa were below 25 % and 4 %, respectively. These indicate that extra-early maize hybrids' response in one environment did not reliably predict the maize response in the other with respect to the traits concerned. Mean yields of the maize hybrids were 4.9 and 3.3 t/ha in -free environment and under infestation, respectively. Among the 150 hybrids, LINE 61 × LINE 49 exhibited the highest base index value of 13.6, marking it as the most -resistant/tolerant hybrid identified in the study. Genotype main effect plus genotype × environment biplot analysis identified LINE 44 × LINE 55 and LINE 61 × LINE 49 as stable and high-yielding hybrids in -free and -infested conditions, respectively. These hybrids are recommended for on-farm evaluation, and if found superior, should be subsequently released to maize growers in areas affected by to boost maize production and contribute to food security in Africa.

2. Gender disparities in the adoption of improved management practices for soybean cultivation in North East Nigeria.
PMID:日期:2025-08This study examined gender disparities in the adoption and intensity of improved soybean management practices among 800 farming households in Borno State, Nigeria, with equal representation of male-led and female-led households. The findings reveal that while both male and female farmers adopt improved soybean varieties, fertilizer, and herbicides, the intensity of adoption varies due to differences in socioeconomic constraints. Male farmers demonstrated slightly higher adoption rates across all practices, particularly for herbicide use. However, financial and market-related barriers, such as high input costs and distance to seed markets, disproportionately hindered female farmers' ability to fully integrate improved practices into their farming activities. The analysis indicates that the adoption of improved soybean varieties by male farmers was mainly influenced by income and pest/disease constraints, whereas female farmers were more affected by age, extension visits, and community tenure. Herbicide use among male farmers was driven by farm size and input costs, while for female farmers, it was influenced by education, input costs, and proximity to seed markets. Fertilizer adoption among male farmers was linked to income and farming experience, whereas female farmers' fertilizer use was shaped by farm size and financial constraints. Ordered probit regression results suggest that age negatively affects adoption intensity for both genders, but income and community tenure play a stronger role for men, while market access and cost barriers are more significant for women. Improving access to extension services can significantly enhance adoption rates, especially for female farmers who face higher input costs and limited access to seed markets. Targeted subsidies and credit programs tailored to smallholder farmers will help alleviate financial barriers, enabling both men and women to invest in essential inputs and expand production. Strengthening rural infrastructure, including better road networks and input market accessibility, will further reduce logistical challenges and support increased soybean cultivation.

3. Towards sustainable management of cassava mosaic disease: The impact of awareness campaigns in Benin.
PMID:日期:2025-06Transboundary diseases, such as cassava mosaic disease (CMD), represent a significant risk to food security and the livelihoods of millions of households in sub-Saharan Africa. To address this issue, awareness campaigns have been conducted targeting farmers and stakeholders within the cassava secor. The objective of this study is to quantify the impact of these awareness campaigns on the knowledge of CMD, the adoption of management practices, and the incidence of the disease in cassava fields. A random sample of 305 farmers and 77 cassava fields in Benin was selected for data collection. To account for potential selection bias associated with observable characteristics, we applied Propensity Score Matching (PSM). The results indicate that farmers who participated in the training demonstrated significantly higher levels of CMD knowledge and were more likely to adopt a greater number of management practices, which ultimately led to a reduction in the prevalence of the disease in their fields. However, CMD symptoms were still prevalent in the majority (61,04) of cassava farms, regardless of participation in the campaigns, due to the lack of healthy planting material and the abundance of whiteflies. These findings suggest that awareness campaigns can significantly improve farmers' knowledge and encourage behavioural changes in the identification and adoption of sustainable CMD management practices. It also shows the need to provide famers with healthy cuttings for more effective disease management.

4. Evaluation of formulated strigolactone analogs for Striga management in Kenyan agriculture.
PMID:日期:2025-06, an obligate root parasitic weed affecting cereal crops, poses a significant threat to global food security in Sub-Saharan Africa (SSA). Germination of Striga seed largely relies on signaling molecules released by the host roots, mainly strigolactones (SLs). Suicidal germination is an effective strategy for reducing Striga seed banks in infested soils by applying SL analogs in the absence of a host. However, the challenge remains in developing suitably formulated SL analogs for field application. In this report, we assessed the activity of two SL analogs, MP3 and Nijmegen-1, in both granular and liquid formulations in laboratory and greenhouse settings, and conducted mini-field and field trials to evaluate their effectiveness under farmers' conditions, using maize as the host crop in Kenyan agriculture. We observed a significant induction of Striga seed germination reaching up to 56 % in laboratory germination bioassays and a reduction in Striga emergence by up to 77 % in greenhouse pot studies. In mini- and field trials in different infested fields, we recorded up to 80 % and 65 % reduction in Striga emergence, respectively. In conclusion, the formulated SL analogs demonstrate significant potential to reduce Striga infestation in maize fields in Kenya and are promising candidates for use by farmers due to their simplicity, ease of handling, stability, and effectiveness.

5. The role of fruit trees in reducing food insecurity and improving nutrition security of rural households: A case study of the KwaZulu-Natal province, South Africa.
PMID:日期:2025-06Despite calls to increase fruit consumption, food and nutrition security strategies often overlook the inclusion of fruit trees in the rural food systems. Hence, this study investigated the role of fruit trees in reducing food insecurity and improving nutrition security among rural households in the KwaZulu-Natal province, South Africa. Descriptive statistics, household food insecurity access scale (HFIAS), household food insecurity access prevalence (HFIAP), food consumption score (FSC), principal component analysis (PCA), and ordered logit model were used to analyze survey data from 305 households. The results showed that only 29.8% of the households were food secure, while the rest were either mildly (36.4%), moderately (27.9%), or severely (5.9%) food insecure. Moreover, 4.6% of the households consumed poor diets, 23.0% of the sampled households were at the borderline, and 72.5% consumed an acceptable diversity of food groups. The ordered logit model findings showed that growing fruit trees, consumption of wild fruits, household size, off-farm income, access to irrigation, access to training, livestock ownership, and psychological capital significantly influenced household food insecurity and nutrition security. The study recommends the implementation of awareness campaigns promoting the planting of fruit trees and the consumption of locally available wild fruits. There is a need for nutrition-related training programs and workshops to enhance awareness of the importance of growing and consuming fruits among rural households. The collective participation of the private sector, government, researchers, civil society organizations, policymakers, politicians, and farming rural households in building awareness is also recommended.

6. Patterns of systemic problems in Ghana's poultry value chain: A group model building approach.
PMID:日期:2025-04Ghana's poultry sector faces different interrelated systemic challenges, often diagnosed in isolation, leading to interventions that neglect unintended consequences across the value chain. Consequently, a holistic prognosis of the impact of these systemic problems that considers the different facets of the poultry industry is required. This paper aims to examine the system archetypes emerging from the inherent industry-level and farm-level problems in Ghana's poultry sector. Adopting a participatory group model building process, causal loop diagrams and feedback loop analyses were applied to understand the interacting factors in four systemic problems prioritised by stakeholders in Ghana's poultry value chain. Four causal loop diagrams were mapped for these systemic problems; inadequate research funding low adherence to biosecurity measures at the farm level; lack of access to credit; and () the competition from cheap imports of poultry meat products. The findings highlight three emerging problem archetypes. First, the underachievement archetype, specifically the limit to growth, emerges when technology adoption due to increased research funding interacts with the non-adherence to biosecurity measures as a cost-cutting strategy at the farm level. Second, the out-of-control archetype emerges when the misuse of antimicrobials due to the non-adherence of biosecurity measures interacts with the industry's collapse and the consequential surge in chicken imports into the country. Third, the relative achievement archetype emerges from the reinforcing feedback loop which centres around the surge in imported chicken as a response to looming food insecurity concerns arising from insufficient domestic supply. The "" archetype is thus created, where importers in the poultry value chain become more prosperous at the expense of the entire industry. The paper presents solutions to the emerging problem archetypes, providing stakeholders with a chance to evaluate the unintended consequences of proposed government policies aimed at rejuvenating local poultry production.

7. {"_":"Agronomic performance and consumer acceptability of improved water yam ( L.) varieties in the Republic of Benin.","i":["Dioscorea alata"]}
PMID:日期:2024-12White yam ( L.) is widely cultivated, and is a staple food in the Republic of Benin. However, its production is highly sensitive to soil infertility, leading to low yields over the years. In order to address the challenges of land reduction and climate change, it is crucial to introduce more adapted yam varieties to traditional Beninese agriculture. Water yam ( L.) varieties are viable options, as they need less soil fertility and yield more than , but have a poor culinary performance. The aim of this study is to assess the agronomic and culinary performance of 15 improved water yam genotypes developed by the International Institute of Tropical Agriculture (IITA) compared to local cultivars. In 2022 and 2023, multilocal trials (4 sites) were performed in the yam-growing areas, and nine villages were selected for culinary evaluation. Linear mixed-effects models and generalized mixed-effects models showed significant differences (p < 0.05) in location, year of experimentation, and certain evaluated agronomic parameters. The improved varieties had a strong likelihood of producing small tubers that could be used as seeds. The agronomic and culinary performance of local water yam accessions has been superior to that of improved varieties. Due to its numerous medium tubers, TDa_1508044 could be introduced for production of yam chips. TDa_1510080, which showed a stable high yield throughout the trial sites, and TDa_1510119, which gave a great number of marketable large-size tubers, showed the best agronomic performance with a yield of more than 25 t/ha. TDa_1510043, TDa_0000194, and TDa_1515030 improved varieties that performed well in both culinary and agronomic ways could be widely adopted by farmers in the yam-growing areas of Benin.

8. Practices of maize handling and nixtamalization to reduce fungal toxin exposure in rural Guatemala.
PMID:日期:2024-11-12Fungal toxins in local food supplies are a critical environmental health risk to communities globally. To better characterize hypothesized toxin control points among households, we conducted household surveys across four departments (first administrative division) in Guatemala. Data gathered included maize harvesting, processing, storage, and traditional nixtamalization practices. In total, n = 33 households participated in the survey and were from 4 unique departments, 17 unique municipalities, and represented 4 different languages. The results suggested that the majority of households consumed a combination of personally cultivated and purchased maize. There was significant variation in how this maize was stored, in regards to pre-processing (kernel vs whole cob), as well as storage system type. For nixtamalization, the largest differences in practices (e.g., cooking time) were based on household size while the majority of households reported practices that aligned with previously reported best practices. Lastly, all reported maize-based food products produced by households utilized the nixtamalization process except one. Current maize handling and nixtamalization practices reported by a majority of households aligned with best practices, however, with locally tailored and culturally sensitive guidance disseminated by key stakeholders, the prevalence of best practice use among households can be improved. Further community-based research on traditional farming and nixtamalization practices can improve these recommendations.

9. Analyzing gender gap in agricultural productivity: Evidence from Ethiopia.
PMID:日期:2024-03Women make up more than 50% of the agricultural labor force but contribute less than 30% to agricultural productivity. Agriculture is the main source of livelihood in Ethiopia but by contributes more than 35% to GDP, 90% to forex earnings, and 70% to employment sources. So Improving economic well-being ensuring sustainable development, and reducing poverty is impossible by ignoring the role of women. Consequently, the main objective of the study is to investigate the gender gap in agricultural productivity using national Panel data of 3474 households which were collected in 2017 and 2019 by the Policy Studies Institute for AGP II baseline study and midline evaluation. Among these, 69% (2404) were male-headed and 31% (1070) were female-headed households. The panel data were combined with DID, Oaxaca Decomposition, and the Random effect Tobit model to investigate the gender gap. The result from the DID Method of Impact Evaluation shows that female-headed households were less productive by 3.7% and 2.05 quintals per hectare when measured in terms of value in birr and quintals per hectare compared to male-headed households. In contrast, male-headed households were more productive by 4% and 2.05 quintals compared to female-headed households. Additionally, the results from the pooled and random effect Tobit model showed that soil fertility, sex of the household head, slope of the land, total livestock holding in TLU, extension contact, use of inorganic fertilizer, credit use, machinery use, and plantation method are among the determinants of the gender gap in agricultural productivity. Furthermore, results from the Oaxaca decomposition show that a gender productivity difference between male and female-headed households was roughly 11.2% when measured by value and 5% when measured by an area-weighted formula. The main finding of the study is that endowment effects were less likely to have a significant impact on the productivity gap than structural effects did. Differences in the unexplained characteristics of men and women may also contribute to the considerable productivity gap between male-headed and female-headed households. Therefore, working on women's empowerment to improve their structural disadvantages through various training programs that favor women or gender-mainstreamed extension training programs for lowering gender productivity differentials is a possible policy option.

10. Dealer-customer partnership in rice production demonstration: Assessment of private extension system in Bangladesh.
PMID:日期:2023-12Traditional public extension worker-farmer cooperation in rice production demonstration is not working efficiently, therefore, private partnership-based demonstration has been attempted to introduce as its alternative very recently involving dealer-customer farmer. The study evaluated the private extension services rendered through dealer-customer farmer cooperation in Bangladesh. Thirty-three rice seed dealers and ninety-two customer farmers formed the samples for the study. Face-to-face interviews were employed as a quantitative method while focus group discussion was used as a qualitative method in the present study. Involving in the private rice production demonstration approach, customer farmers indicated high profit, greater involvement in decision-making, and improved marketing skills as the major advantages; while the dealers stressed the benefit received by the small farmers, improvement in their decision-making capacity and increased local rice production. However, the slow distribution of inputs during the production period was a weakness in the arrangement, which was mostly because of the dealers' lack of understanding of the customer farmers' needs. The private extension system being a new concept in the country may be observed over a period and gradually extended to the nooks and crannies of the country.
