Seed-borne fungi and seedling performance of Provitamin A Maize (Zea mays L.) stored in different packaging materials and temperatures
(Faculty of Agriculture and Forestry, University of Ibadan, 2023) Aduramigba-Modupe, A. O.; Adedire, O. M.; Fashola, O. O.; Adeoya, O.
Maize (Zea mays L.) is widely cultivated across most agro-ecological zones in Nigeria. However, fungi are commonly associated with maize from the field through storage, reducing the economic value and viability of stored grains. Effective control of post-harvest storage fungi is therefore essential. This study evaluated the effects of cold storage (0–5°C) and room-temperature storage (25 ± 5°C) of maize grains preserved in plastic containers, aluminium packs and tin silos over a 120-day storage period on seedling characteristics and fungal occurrence.
Three provitamin A maize varieties, PVA SYN2, PVA SYN6 and PVA SYN8, were used in the experiment. Data were collected on fungal incidence, germination percentage, root length and shoot length. Fungal species were isolated on Potato Dextrose Agar (PDA) and identified using standard procedures.
The fungi identified from the stored maize varieties were Aspergillus niger, Aspergillus fumigatus, Aspergillus flavus, Rhizopus stolonifer and Curvularia lunata. In general, Rhizopus stolonifer (50.00%), Curvularia lunata (46.67%) and Aspergillus fumigatus (40.00%) had the highest frequencies of occurrence in the provitamin A maize varieties.
Although storage temperature, storage materials and fungal contamination did not significantly affect germination percentage of the three provitamin A maize varieties, seedling performance, as measured by shoot and root lengths, varied significantly among treatments. The most effective storage conditions for minimizing fungal contamination were preservation in tin silos and aluminium packages under low-temperature conditions.
The study therefore recommends storing provitamin A maize grains in tin silos or aluminium packs at low temperatures to reduce fungal contamination and enhance seedling growth performance during storage.
Development of a Low-Cost 3D-Printed Isothermal Amplification (LAMP) Device Prototype for Early Detection of Fusarium oxysporum f. sp. Lycopersici.
(Faculty of Agriculture and Forestry, University of Ibadan, 2025) Adedeji, K. O.; Aduramigba-Modupe. A. O.; Arogundade, O.
Fusarium wilt, caused by Fusarium oxysporum f. sp. lycopersici (FOL), is a major threat to tomato production, resulting in significant economic losses worldwide. Early detection of the pathogen is essential for effective disease management. However, conventional diagnostic methods are often time-consuming, require sophisticated laboratory infrastructure and typically detect the pathogen only after visible symptoms have developed.
Loop-Mediated Isothermal Amplification (LAMP), a highly specific and sensitive DNA amplification technique, operates at a constant temperature and eliminates the need for complex thermocyclers. This study aimed to develop a low-cost, portable and efficient 3D-printed LAMP device for the rapid field detection of Fusarium oxysporum. To improve detection accuracy, real-time colorimetric analysis was incorporated to minimize contamination risks commonly associated with endpoint detection methods.
The device was constructed using widely available and cost-effective components, including coffee capsules, phase-change materials (PCM), 3D-printed materials and electronic components, ensuring affordability, precision and scalability. A comparative evaluation of the developed system against conventional laboratory-based diagnostic techniques demonstrated its reliability in detecting Fusarium oxysporum directly from crude infected plant samples.
The results indicate that this innovative LAMP platform provides a sustainable, practical and cost-effective solution for early disease diagnosis, particularly in resource-limited agricultural environments. This research establishes a foundation for the broader adoption of low-cost, field-deployable molecular diagnostic technologies, thereby contributing to improved crop protection, disease management and sustainable agricultural practices.
Evaluation of Rhizobia Inoculants and Fungicides in the Management of Fusarium Wilt Disease of Cowpea (Vigna unguiculata (L.) walp)
(KWASU Press and Publishing, Kwara State University (KWASU), 2025) Oke, B. F.; Aduramigba Modupe, A. O
"The antifungal potential of Rhizobium inoculants and their compatibility with fungicides in controlling Fusarium oxysporum f. sp. tracheiphilum (FO) in cowpea were investigated. Fifty cowpea nodules were collected from fields in Kano and Ibadan, Nigeria, and used for the isolation, authentication and identification of Rhizobium strains. The antagonistic potential of the two best-performing strains (R2 and R3) was evaluated in vitro against Fusarium oxysporum f. sp. tracheiphilum, with USDA 2677 (R1) serving as the reference strain.
Compatibility tests between fungicides and Rhizobium strains were conducted using cowpea seeds dressed with four fungicides. The treated seeds were subsequently coated with the Rhizobium strains R1, R2 and R3. Seven local strains (Ibadan 1, Ibadan 2, Ibadan 16, Kano 18, Kano 19, Kano 42 and Kano 49) were identified as Bradyrhizobium species.
In terms of nodulation, Ibadan 16 and Kano 19 produced 9 and 7 nodules, respectively, compared with 11 nodules produced by the reference strain. Ibadan 16, Kano 19 and R3 significantly inhibited the mycelial growth of Fusarium oxysporum f. sp. tracheiphilum. Among the fungicide treatments, TMD (6.33 × 10⁸ CFU/mL) and IMC (6.25 × 10⁸ CFU/mL) enhanced Rhizobium growth more than MC (4.30 × 10⁸ CFU/mL), whereas CM completely inhibited the growth of all Rhizobium strains. The untreated control recorded the highest bacterial population (3.89 × 10¹⁰ CFU/mL).
The fungicide combinations Thiamethoxam + Metalaxyl-M + Difenoconazole and Imidacloprid + Metalaxyl + Carbendazim were compatible with the indigenous strains Ibadan 16 and Kano 19. The indigenous Rhizobium strains competed favourably with the exotic reference strain (USDA 2677) and are therefore recommended for use in cowpea inoculant production."
Challenges of teaching, learning and application of AL-Fara’id in Lagos and Oyo States, Nigeria: an exposition
(Nigerian Association of Teachers of Arabic & Islamic Studies (NATAIS), Lagos State Branch, 2025-01) Busari, J. M.; Abdulsalam, M. K.; Adeoye, T. O.
Application of Islamic law (Shariah) in Yorubaland, Southwest Nigeria has been a herculean task for over a century due to its non-statutory recognition. The 1999 Constitution of Nigeria as amended (2011) recognizes the application of shariah on Muslim personal laws, such as succession, marriage and divorce as provisioned in the Qur'an and Sunnah. However, its absence creates challenges in the application of Islamic law of inheritance (al-fara’id) on Muslim estates amidst its obligation in Islam and dearth of its teaching and learning among Muslims for decades, thus, it affects Muslims socially, economically and religiously. Therefore, this paper concisely unearths the institutionalization of al-fara’id in Islam and its socio-economic benefits. It then analyzes the concept of teaching and learning in Islam and the challenges of al-fara’id’s teaching, learning and application among Muslims of Lagos and Oyo states. It was discovered that non-statutory application of shariah, meagre literary production of al-fara’id books, shortage of competent hands to teach Islamic law in both western and Islamic schools among others are the challenges facing alfara’id teaching, learning and application. The paper then suggests that Muslims at all levels should agitate for the implementation of Shariah in Yorubaland and support the activities of the Independent Shariah Panels and all available scholars of al-fiara’id in Lagos and Oyo States in promoting the culture of applying Islamic law of inheritance on estates as enjoined by Allah under Islamic law.
Yoruba muslim youths and the problems of identity in the midst of diversity
(Faculty of Social Sciences, National Open University of Nigeria, Abuja, Nigeria, 2018-12) Abdulsalam, M. K.; Adeogun, J. A.
Identity is an ambiguous term with assumptions about its meaning and relevance to peoples' understanding of Muslim youths' response or behaviour to issues in the society. Therefore, this study seeks to examine the way of life that defines who, a Muslim youth is. Is he one whose practice of Islam separates him from others or one whose Islam accommodates innovations and diversities? Taking cognizance of the position of Muslim youth to the Yoruba culture and the interactional patterns that characterize everyday encounters among people; greetings by prostration, kneeling and bending as major ways by which Yoruba express respect for their elders, dressing for both male and female Muslims as outlook to life, have all become point of arguments and diversities among Muslim youths in Ibadan. On account of these, some youths deliberately reject the taslim (Islamic greeting) of their fellow Muslims, they also disrespect elders who do not share their opinions. These issues have led to disputes and malice which shamelessly resulted to enmity and disunity within the Muslim ummah. Consequently, this paper attempts to find solution to these problems of identity among Muslim youths.
