    Highly organised direct farmers market: analysis of forms, characteristics, operations and women involvement in Japan
    (2007) Tijani, S. A.; Yano, I.
    This study was based on the primary information collected from women farmers and coordinators of selected direct farmers markets in Sera and Ohnan Chuo, Hiroshima and Shimane prefecture respectively in Japan. Stratified and purposive sampling techniques were used to select respondents and direct farmers markets Information from direct farmers market coordinators and women farmers/processors was collected through interview schedule and structured questionnaires respectively. The study revealed that most of the direct farmers market studied were established for economic and social assistance of farmers. Requirements to participate varied from market to market. Low profit, competition and lack of sale were the major problems facing the respondents. Comparison of women farmers’ income from agriculture and non agriculture suggests better condition in agriculture than seeking employment outside the industry. Although, respondents were being empowered economically in some market and socially in others through participation in direct farmers market but both economics and social as well as political empowerment are essential for the market participants through involvement in the management activities of the market. Physically presence of farmers with their products on weekly, fortnightly or monthly basis should be initiated in order to build more social relationship among farmers and between farmers and consumers.

    Assessment of current status of women farmers in Japan using empowerment indicators
    (Asian Network for Scientific Information, 2007) Tijani, S. A.; Yano, I.
    This research assessed the current status of Japanese women farmers using universal measurement of women empowerment. Two prefectures, Hiroshima and Shimane were selected. Stratified sampling technique was used to select respondents from each village while structured questionnaire was employed to collect data on economic, social, familial, legal, mobility and political status of the respondents. The result shows that status of women farmers was improved in the recent time compared to years back. This was revealed in the favourable responses to some statement questions such as; freedom and participation in voting, relationship with husband, participation in outside work and freedom of movement. However, their status as unpaid workers on family farms, lack of freedom to borrow and lend, inability to express their mind over the children to mother-in- law were the prevailing items of their disempowerment. Classifying respondents on the overall empowerment shows that majority of them were highly empowered. Inferential analysis using t-test to compare women farmers past and present status shows a significant difference, t = 4.827, p = 0.000. Relationship between personal characteristics of women farmers and their present empowerment status using Pearson Product Moment Correlation (PPMC) coefficient r shows negative correlation between age and all empowerment indicators. Also marital status has negative correlation with familial and legal empowerment while mother-in-law and familial empowerment were positively correlated. It therefore suggests that status of women farmer in Japan has improved, compare to their situation years back.

    Effects of lead on performance and nutrient quality of two cowpea varieties
    (2003) Fadina, O.O; Opeolu, B. O
    The effects of lead on plant growth, yield and nutrient quality of two cowpea varieties (IT94K-4403 and IT93KZ-8-21-23-3) were studied. Soil and seeds analyses for lead before planting and after harvest revealed variable decreases in lead levels in contaminated soil after harvest. While lead was not detectable in the planted and harvested seeds. There were no significant differences in the various lead contamination levels with respect to germination days and maturation days. Lead contamination was found to have adverse effects on the yield of cowpea. The variety IT94K-4403 showed no variation in protein after harvest with the different levels of lead contamination, IT93KZ-8-21-23-3 on the other hand showed variable deceases in protein content.

    Effect of Spent Lubricating Oil on Some Growth Parameters of Two Varieties (TGXl485 - ID and TGXl448 - 2E) of Soybeans, (Glyzine max. merril)
    (2002) Mbong, G. A; Fadina, O.O; Focho, B. A,; Azo, W. M; Seino, R. A.
    The effects of spent lubricating oil on the growth of two varieties of soybean (TG x 1485-ID; (V1)) and (TG x 1448-2E; (V2)) were investigated in the laboratory and greenhouse experiments. In all the plants treated with spent lubricating oil, germination was delayed when compared with the Controls. Also results from growth parameters such as stem height/plant, number of leaves/plants, - number of nodes/plants and number of branches/plant indicated that spent lubricating oil had some adverse effects on the growth of soybeans. However, V1 seems to be more tolerant to contamination by spent lubricating oil in terms of growth indices than V2, which suffered most. Generally, while V2 produced a net higher dry pod weight/plant, V1 produced less dry weight/plant. It was generally observed in the study that with increasing level of oil contamination, the toxicity of the oil was more pronounced

    Reduced Morphological Root Features of Anthracnose Infected Cowpeas (Vigna unguiculata (I.) Walp)
    (2002) Ajari, I. O.; Fadina, O.O
    ln a green house experiment to determine the effects of anthracnose disease caused by collectricum lindemuthianum on cowpea, sterilized siols in planting pots were used for planning two susceptible cowpea varieties (Ife Brown and 1782-60). The seedlings were inoculated with the inoculum meal of the pathogen after 3 weeks of planting. The results obtained show that characteristics tan to brown anthracnose symptoms had appeared on the leaves of both varieties after 3 weeks of inoculation, while the roots of the infected cowpeas were observed to be morphologically different from the roots of the uninfected plants. Similarly, infected plants were smaller in size and a marked reduction in their yield IT82f 60 (35%) versus Ife Brown (19%). The reduction of the plant structures and yield of the infected plants was suspected to have been as a result of the anthracnose disease

    Survey of Downy Mildew Disease of Maize (Peronoscleropora Sorghi) For Appropriate Control Strategies
    (2000) Fadina, 0.0; Adeoti, B. O.
    The study sets out to find the various factors militating against the effective control of the downy mildew disease of maize in some local government areas of Oyo and Ogun States (Nigeria). Lack of adequate communication between the farmers and researchers and the unavailability of downy mildew resistant seeds at the appropriate time and at affordable prices are some of the factors militating against the effective control of the downy mildew disease of maize. The testing of relationships with chi-square between farmers educational levels and incidence of disease shows that there is no relationship between the two i.e. X2 cal > X2 tab at 95% significant level. The chi-square test also indicated that there is still the occurrence of the disease irrespective of whether farmers have access to extension agents or not because X2 cal = 7.98 while X2 tab = 5.99 at 95% significant level. The adoption of an integrated pest management approach, close linkage between the farmers and researchers and the provision of technical advice by extension agents were suggested

    Toxicity of gamma-benzene hydrochloride (y-bhc) to oreochromis niloticus (pisces: cichlidae)
    (2000) Fadina, 0.0; Taiwo, V.O; Ogunsunmi, A O; Agbede, S A
    The toxicity of gamma-benzene hydrochloride (y-BHC) to Oreochromis mlolicus was evaluated in a static bioassay system A various concentrations and ponods of exposure, changes in behavioural responses and ortahbes were recorded in the test fish, while no such responses or any molality was recorded in the control fish throughout the period of the experiment increasing concentration and periods of exposure to y-BHC caused uncoordinated movements, erratic swimming behavior and extreme dullness prior to death of the lest fish. There are progressive heamoconcentration, hyperproteinaemia, hypernatraemia, decreased plasma cabon concentration, hypoglycaemia and increased plasma levels of ALP, AST and ALT will increasing concentration of y- BHC and period of exposure of test fish Death of test fish pccued cathest in the highest concentration of y- BHC(200ppm) and with increasing ponods of exposure postmortem lesions observed in the test fish include haemorrhagic and necrotic enlentis and myocarditis, hepalocellular degeneration and necrosim and non-suppurative meningoencephalitis it is concluded that y-BHC is very toxic to O.nilolicus, causing severed ncule denydration,haemoconcentration, organ damage and death. Hence, it is suggested that the use of y-BHC to properly controlled and regulated by appropriate legislation in order to prevent its bioaccumulation in the environment and immnent disastrous effect on the ecosystem

    Biological Control of Root Knot Nematodes (Meloidogyne spp.) On Tissue Cultural Banana (Dwarf Carvendish Var. Basarai)
    (2004) Fadina, O. O; Nadgauda, S. R
    Biocontrol powder Phule Trichoderma has been successfully used on a number of horticultural crops. The present investigation was carried out to explore the nematicidal properties of Phule Trichoderma against the root-knot nematode (Meloidogyne spp.) infesting the tissue culture banana (Dwarf Cavendish - var. Basarai). In vitro tests slowed that the various concentrations of Phule Trichoderma prevented nematode egg hatching and also resulted in 100% mortality of nematode juveniles. Tissue culture banana plants were also dipped into various concentrations of Phule Trichoderma before planting out into plastic bags. Plant were inoculated with 250 nematode juveniles and alter ten days, the roots were stained with cotton blue lactophenol and nematodes were counted under a dissecting microscope. The results indicated that the higher the concentration of Phule Trichoderma in banana plants, the lower the ability of the nematode to penetrate the roots. Furthermore, the nematode juveniles that penetrated the treated roots were found dead. This could have resulted from the toxic metabolites produced front Phule Trichoderma. Also, root zone treatment of plants treated with Phule Trichoderma prevented the development of giant cells and roots knots in treated plants while the development of giant cells and root knots were observed in untreated plants exposed to nematode infestation.
