    INFLUENCE OF SEED PRIMING ON YIELD, MORPHOLOGICAL AND PHYSIOLOGICAL CHARACTERISTICS OF WATER-DEFICIT STRESSED LOWLAND RICE
    (West University of Timisoara, Romania, 2021-08-28) Kareem, I; Ismail, M.R; Puteh, A.B; Kareem, S.A; Lawal, O.I; Adekola, O.F; Faseyi, A.F; Olaniyan, J.O; Yusuf, S.Y; Lawal, M.T; Abdulkareem, K.A; Olayinka, B.U; Abdulaziz, A.; Ahmed, O; Baba, H.S; Kuranga, H.A; Lawal, Q.O; Musa, A.I; Oyelade, H.Y
    One of the potential ways of increasing rice production to cater for ever increasing population of Malaysia is to extend the production area of lowland rice through its production as upland rice. Therefore, this research was conducted to determine the effects of seed priming in alleviating water deficit stress in lowland rice produced as upland rice. The treatments used were 100mM calcium chloride dihydrate for duration of 48hours and temperature of 25oC, 40% w/v polyethylene glycol (PEG) 6000 for a duration of 48hours and temperature of 25oC, 100ppm kinetin for a duration of 24hours and temperature of 4oC, 200ppm methyl jasmonate for a duration of 24hours and temperature of 4oC, stressed control (unprimed seeds) and the unstressed control (unprimed seeds with adequate irrigation). The experiment was laid out in randomized complete block design (RCBD) with three replications. Data were collected on classical growth parameters, germination pattern, gas exchange characteristics, yield and yield components. It was found that priming MR219 rice with PEG could enable the variety to be produced as upland rice with little yield reduction because PEG priming was the best in individual seed mass, final yield, harvest index and water use efficiency. It is, therefore, concluded that 48hours of priming with 40%w/v polyethylene glycol at 25oC be used for MR219 rice seeds whenever MR219 rice variety is to be cultivated as upland rice.

    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.

    Pathogenicity and Control of Phomopsis sp. Associated with Yam Rot Using Bark Extracts of Mangifera indica L. and Parinari polyandra Benth
    (Department of Crop Protection, Faculty of Agriculture, University of Ilorin, Ilorin, Nigeria, 2017) Baba, H.S; Ahmed, O; Yusuf, S.Y; Lawal, R.A; Adebayo, O.V; Ojomu, 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.
