    Assessment of the Performance and Barriers to Small-Scale Fish Marketing in Dutsin-Ma Local Government Area, Katsina State, Nigeria
    (2014) Tiri,G.D; Oshoke J; Nabinta, T.R; Olatinwo L.K
    The importance of fishery products and its marketing has always been an important discourse among scholars due to its contribution to gross national product and per capital income of fishermen and marketers in nations with fishing capabilities. In Nigeria, however, given increasing demand for fish, there seems to be a potentially strong market for the product. The study seems to quantify the determinants of factors influencing the performance of small-scale fish marketing in Dutsinma local government of Katsina State. Kendalls coefficient of concordance was used to test the agreement between ranked constraints of small-scale fish marketing in relation to performance. A sample size of (50) Fish marketers were drawn by a simple random technique from a registered population of(102) for two months and a structured questionnaire was used to elicit their responses from the Market. Data was analysed using statistical packaged for social sciences (SPSS). Results of the analysis indicated that age of marketers (p<0.01), years of formal education (p<0.01), annual cost incurred (p<0.01), membership of cooperative society (p<0.01) initial capital invested (p<0.01 are the most influential determinants of small scale fish marketing. The Kendalls coefficient of concordance indicates that there is 78% agreement between the respondents in the ranking of constraints in relation to performance, poor access to credit facilities, poor market infrastructures and poor record keeping habit are the most important constraints faced by small fish marketers. Based on the results we recommend a flexible and favourable policy geared toward helping young entrepreneurs through improved market infrastructures.

    Comparative evaluation of forage grasses for stability analysis using GGE biplot and AMMI and forage yield modelling
    (Research on Crops, 2020) Lawal O.O; Abdulrahaman O.L; Ayanda I.F; Ishola Hakeem; Olatinwo L.K; Ibrahim U.Y
    The need for cultivation of forage grasses to feed animals, as a way of ameliorating the clashes between herders and crop farmers cannot be over emphasized. Therefore, this study was conducted during 2019 at three diverse agro-ecological zones in Kwara State, Nigeria to assess the yield potential, stability, and the possibilities of improving forage yield through secondary traits. Hence, three forage grasses (Elephant grass, Pennisetum purpureum; Gamba grass, Andropogon gayanus; and Ruzi grass, Brachiaria ruziziensis) were laid out in randomised complete block design (RCBD) wherein data was collected on vegetative, stress index traits and yield and were subjected to analysis of variance (ANOVA). Traits with significant G × E were subjected to stability analysis using genotype × genotype × environment interaction (GGE) biplot and additive main effects and multiplicative interaction (AMMI). Structural equation model was used to depict the association between yield and secondary traits. The results revealed significant (p < 0.05) difference among forage grasses for yield and other traits, hence, they are amendable to selection and improvement through breeding efforts. AMMI and GGE biplot effectively identified the best and most stable forage grass as Pennisetum purpureum (28.59 t/ha) for general adaptations, and Ruzi and Gamba for target environments. Plant height, number of tillers, leaf area, dry matter content and stay green are valuable secondary traits that are employable in improving forage yield. Pennisetum can meet the feed demand of herder’s animals, which, if adopted for cultivation and use, can reduce the incessant crises between farmers and herders in Nigeria.
