    Assessment of bio-agent (Trichoderma Harzianum) in the management of two pepper varieties infected with root-knot nematode (Meloidogyne Incognita)
    (ACTA UNIVERSITATIS SAPIENTIAE AGRICULTURE AND ENVIRONMENT, 2019-01-30) Izuogu, N.B.; Baba, Halimat S.; Winjobi, E.O.
    Two field trials were carried out at the Teaching and Research Farm of the University of Ilorin in the 2012 and 2014 planting seasons to find out the effeciency of Trichoderma harzianum as a bio-control agent in controlling root-knot nematode (Meloidogyne incognita) in two pepper varieties (F1 Nikita and Gianfranco Fuscello). A 2 × 2 factorial design fitted into a randomized complete block design (RCBD) was used with 5 replications. The T. harzianum filtrate significantly increased plant height, numberof leaves, and yield. The control showed higher root galling and soil nematode population.Varietal differences showed that F1 Nikita performed significantly better than G. Fuscello. The combination of Trichoderma and F1 Nikita appears effective for managing root-knot nematodes.

    (2020-07-31) Baba, Halimat S.; Izuogu, N.B.; Oladimeji, A.; Olamilekan, H.
    Assessment of plant Lantana camara and Bridelia ferruginea based aqueous extracts and powdered form were evaluated on root-knot nematode pest of two tomato varieties at the Screen house of the Department of Crop Protection, Faculty of Agriculture, University of Ilorin, Ilorin, Nigeria. The experimental design was a completely randomized design and was replicated four times. The two varieties of tomato (Roma – VF and UC 82 – B) have been confirmed to be prone to root-knot nematode. Three seeds of tomato were planted in each pot that contained 7kg of sterilized soil and later thinned into one; each pot was inoculated with 4,500 root-knot nematode eggs. The plant materials used as treatments were L. camara and B. ferruginea aqueous and powdered with an application rate of 50ml and 20g per pot respectively. Untreated pot served as control. Data collected were vegetative parameters and reproductive parameters of tomato, soil and root nematode population as well as the galling rates. The experiment results revealed that L. camara and B. ferruginea aqueous extracts and powdered significantly increased growth and yield of the two tomato varieties grown in the Meloidogyne incognita nematode inoculated soil, while root-knot nematode population in soil and root were significantly reduced. Gall index was also significantly lower in the L. camara and B. ferruginea treated tomato compared to the un-inoculated control. Lantana camara and Bridellia ferruginea were effective potential measures for controlling root-knot nematode where the soil is heavily infested.

    (Cercetări Agronomice în Moldova, 2017-10-18) Izuogu, N.B.; Saliu, A.R.; Baba, Halimat S.; Olajide, M.C.
    Experiments were conducted at the teaching and research farm of Faculty of Agriculture, University of Ilorin, Nigeria to determine the effect of aqueous extract of Peperomia pelliucida and Terminalia catappa on the management of cyst nematode, Heterodera sacchari on some selected rice varieties. A screenhouse preliminary study was first carried out in December, 2014 to assess the pathogenicity of H. sacchari on ten varieties of rice from which five varieties were selected for field trials. The five selected rice varieties were grown on soil inoculated with cysts of H. sacchari. The field experiment was a 5x3 factorial type fitted into a randomized complete block design (RCBD). Soil nematode population, physiochemical soil analysis and phytochemical screening of the tests plants were carried out. Treatment application of aqueous leaf extract were conducted at the 2nd and 7th weeks after transplanting. Data were collected on the plant height, shoot, root weights, yield and soil nematode population. All numerical data were subjected to analysis of variance (Anova) using GENSTAT statistical package 12th edition and where significant differences were observed, means were separated using fisher’s protected LSD. Results from the study revealed that treatment combination of P. pellucida and T. catappa singly with FARO 60, FARO 61, and NERICA 8 performed significantly higher (p>0.05) than the other rice varieties for most of the growth and yield parameter measured. Significant differences occurred between shoot, root, and yield weight of treated plants and their control counterparts. There was no significant difference between the two plant extracts used with respect to parameters measured. Treated plants performed significantly higher than the control. Based on the results of the study, paddy farmers experiencing H. sacchari infestation are encouraged to treat the field with P. pellucida and or T. catappa, especially when planting FARO 60, FARO 61, and NERICA 8 as these combinations promise to give higher yield.

    MARKET ANALYSIS OF APPLE FRUIT IN SELECTED MARKETS OF LAGOS STATE NIGERIA.
    (INT’L JOURNAL OF AGRIC. AND RURAL DEV., 2020) Belewu, K.Y.; Akinsola, G.O.; Osasona, K.K.; Baba, Halimat S.; Adisa, Q.B.
    This thesis studied the market analysis of apple fruit in selected markets of Lagos state, Nigeria. This project work stemmed from the need to assess the marketing structure, conduct and performance of the fruit in selected markets of Lagos state by using structured questionnaire which was administered to 102 apple fruit marketers in the study area. Data was analysed using descriptive statistics such as frequencies, mean and percentages, gini coefficient, concentration ratio, market margin and efficiency analysis, gross margin analysis, benefit cost ratio, ordinary regression analysis, and likert-type scale. To measure the market concentration: Gini coefficient and concentration ratio (CR4) were used to determine the market structure. The gini coefficient of 85.6% indicated that that there is inequality or high level of seller concentration at this level, a concentration of 47.7% which indicates a weak oligopolistic nature of the market. The performance of the market was efficient and profitable. A marketing margin of ₦4,902,877.0k/month and a marketing efficiency of 114% were obtained by the marketers. The transaction costs affecting the efficiency of the traders were the costs of storage, loading, transportation, and market levy. The three major problems of the traders were price fluctuation, high transportation cost, and lack of credit. Hence, the study suggests that there should be a provision of credit facilities and loans, intervention of government agencies and market association in stabilization of price, and reduction of tariffs and embargo.

    (Horticultural Society of Nigeria, 2017) Izuogu, N.B.; Baba, Halimat S.; Okelade, O.O.
    The experimental trial was conducted at the Teaching and Research Farm, Faculty of Agriculture, University of Ilorin in 2015 cropping season to investigate the nematicidal efficacy of Solanum torvum and Tithonia diversifolia on root-knot nematode infecting two Cucumber varieties; Cucumber – beth alpha and Cucumber Marketmore 76. Initial soil nematode population was increased by incorporation of Meloidogyne incognita infected galled root of Celosia argentea into the ploughed and harrowed field. The experiment was a factorial type fitted into a Randomized Complete Block Design (RCBD ) and replicated four times. Data collection on plant growth commenced two weeks after planting. The fruits were harvested at maturity. Root systems were rated for galling and the initial and final nematode population present in the soil were identified and enumerated. Phytochemical screening was carried out to determine the bio- active ingredients present in the botanicals. All numerical data were subjected to two – way analysis of variance and treatment means separated with Duncan’s multiple range tests at P < 0.05. Results obtained revealed that treated plants were performed significantly higher than their control counterparts especially with respect to yield, reduction in soil nematode population and root gall index. Phytochemical result showed that both Solanum torvum and Tithonia diversifolia contain bio- active ingredients such as alkaloids, tannins, saponin, phenols and terpenoids that are capable of reducing the pathogenicity of root-knot nematode and improving growth and yield.

    (Al-Hikmah Journal of Pure & Applied Sciences (AJPAS), 2017-04-08) Ahmed, O.; Baba, Halimat S.; Yusuf, S.Y.; Lawal, R.; Adebayo, O.V.; Ojumo, J.O
    The antifungal property of Mangifera indica and Parinari polyandra bark extracts against Phomopsis sp. isolated from rotting yam tubers was evaluated. Stock solutions prepared by dissolving 1 g of each extract in 100 ml of sterile water (i.e. 1% w/v) was applied at 1:2, 1:4 and 1:6 (i.e. 1 part of the stock to 2, 4 and 6 parts of the culture medium v/v) in-vitro. The extracts were later applied at 0.5%, 1% and 1.5% w/v as coating on the yam tubers. The plant extracts significantly suppressed the growth of the fungus in vitro and reduced rot development in healthy yam tubers. The percentage inhibition of growth of the test fungus on medium treated with Parinari polyandra bark extract ranged between 10.50 – 21.35 , 19.52 – 43.15 , 29.41 – 50.14 , 33.18 – 51.92 and 27.71 – 47.30 for concentration range between 1:6v/v – 1:2v/v of the stock solution at days 3 , 5 , 7 , 9 and 11 of plating respectively. Percentage inhibition of growth of the fungus on Mangifera indica extract treated medium also ranged between 11.02 – 39.06, 34.93 – 49.32, 34.45 – 52.94, 38.37 – 54.18 and 31.88 – 50.42 for the same concentration range and days after plating respectively. The study showed the potentials of these plant extracts in the control of post harvest rots of yam tubers.

    PATHOGENICITY OF Meloidogyne Incognita IN SELECTED GROUNDNUT VARIETIES AND ITS MANAGEMENT WITH AQUEOUS LEAF EXTRACTS OF WILD SAGE (Lantana Camara L.) AND LOCUST BEAN (Parkia Biglobosa JACQ.)
    (Agrosearch, 2018) Baba, Halimat S.; Izuogu, N.B.; Olajide, M.C.; Dosunmu, O.O.; Ahmed, O.; Saliu, A.R.
    Investigations were conducted to evaluate the pathogenicity of the root-knot nematode, Meloidogyne incognita, on four groundnut (Arachis hypogaea L.) varieties. The efficacy aqueous leaf extracts of Lantana camara and Parkia biglobosa in the management of M. incognita infecting the groundnut varieties was also investigated. A preliminary study was first carried out from November 2014 – January 2015 in a screen house to access the pathogenicity of M. incognita on the four varieties of groundnut. Results obtained from soil and root nematode population led to field trials which involved the management of M. incognita using botanicals. The field experiment which was a 4x3 factorial fitted into Randomized Complete Block Design (RCBD) commenced in August, 2015. The effects of treatment on plants’ height, number of leaves, weight of fruits and on the population of root and soil nematodes were determined. Phytochemical screening of the active components in the test plant extracts was also conducted. Data collected were subjected to analysis of variance (ANOVA) and significant means were separated using Fisher’s protected LSD. Results from the study revealed that the growth parameters, yields and nematode population were significantly higher (p < 0.05) for the treatment combinations of L. camara and P. biglobosa than the control L. camara leaves extract at 100% performed better than P. biglobosa with respect to all the data measured. Phytochemical analysis revealed the presence of alkaloids, saponin, tannin, flavonoids, phenol and glycosides as the active chemical components in the test plants. This bio–active components were responsible for the nematotoxic effect of the leaf extracts. However results indicate that both aqueous extracts of L. camara and P. biglobosa can be used to manage the root-knot nematodes and increase the yield of groundnut without any toxic effects on the plants.
