    (Department of Animal Science, Faculty of Agriculture, Obafemi Awolowo University, Ile-Ife., 1984) Adejumo, John Olusesan
    The effects of plant age at harvest, planting distance, cutting time, frequency and height on the yield and nutritive value of gliricida sepium, cajanus cajan and leucaena leucocephala were studied. The feeding value of leucaena as a fodder source for West African dwarf sheep was also investigated

    Genetics analysis of multiple stress tolerant extra-early maize (Zea mays L.) inbred lines under contrasting environments
    (Department of Crop production and protection, Faculty of Agriculture, Obafemi Awolowo University., 2021) OBISESAN, Oluwafemi Isaiah
    This study evaluated grain yield performance and stability of 210 extra-early maize hybrids across stress and non-stress environments; established the mode of gene action controlling the inheritance of yield and other traits under Striga infestation, drought, optimal conditions and across environments; assessed the combining abilities of the inbreds; classified the lines to heterotic groups based on their combining ability; and determined the efficiency of inbred testers and interrelationship among traits measured. These were with a view to develop and deploy improved hybrids with combined tolerance to these stresses in West and Central Africa.

    Assessment of Group Dynamics Among The Beneficiaries of Fadama 111 Additional Financing in Osun State Nigeria.
    (Department of Agricultural Extension and Rural Development, Faculty of Agriculture. Obafemi Awolowo University., 2023) OLADIMEJI, Folake Victoria.
    The study identified and described the group characteristics of Fadama III AF beneficiaries, analysed the communication and interaction patterns, determined the strength of group dynamics and also examined the influence of conflict on group performance among Fadama III AF beneficiaries. These were with a view to assessing Group dynamics among the beneficiaries of Fadama III additional financing. Multistage sampling procedure was used to select respondents for the study. At the first stage, 50 percent of the participating Local Government Areas (LGAs) were purposively selected from each Agricultural zone translating to 6, 4, 3, LGAs from Osogbo, Iwo and Ife/ Ijesha zones respectively. The selection was based on the local government with higher numbers of participating production groups. At the second stage, 30 percent of the Production Groups (PGs) in each of the selected LGAs were proportionally selected, making a total of 59 PGs. At the third stage, 2 leaders and 2 members from the 59 selected PGs were randomly selected for an interview making a total of 236 respondents for the study. Quantitative data were elicited using structured interview schedule while qualitative data were collected using Focus Group Discussion Guide (FGDs). The quantitative data were analysed through the use of descriptive statistics such as frequency counts, percentages, means and standard deviation while inferencial statistics such as chi- square, multiple linear regression and analysis of variance (ANOVA) were used to draw inferences on the hypotheses. Content analysis were used to analysed qualitative data. The results showed that 44.1 percents of the groups were formed between 2012-2014, 61.0 percent of the groups fund their group through loan or grant from the government, Majority (62.5%) of the group were for financial purposes, 64.4 percent registered between 4 and 6 years ago. Also, 54.2 percent of Fadama III AF groups were into rice production while 85.6 percent of the respondents used face-to-face meeting, and telephone calls as means of communications. About 51 percent had strong group dynamics strength, while 48.7 percent had weak dynamics strength. Year of group establishment, group economic activity in Fadama, sources of group finance, group activity before Fadama had significant association with their group dynamics at p ≤ 0.01. There was a significant association between the perceived positive influence of conflicts and their group dynamics (χ2 = 19.99 p≤ 0.01). This implies that the higher the perceived positive influence of conflicts, the stronger the group dynamics. Also there was a significant association between the perceived negative influence and their group dynamic (χ2 =10.863 p≤ 0.01). This implies that the higher the perceived negative influence of conflicts, the weaker their group dynamics. There was a significant difference in the mean scores of the strength of group dynamics among Fadama III AF beneficiaries across the selected Agricultural Development Projects zones at p≤ 0.05. The study concluded that more than half of the beneficiaries of Fadama III AF group had strong group dynamic strength.

    Facts of farm size and distribution patterns on resource productivity and farm incomes in Kwara State, Nigeria.
    (Department of Agricultural Economics , Obafemi Awolowo University, Ile-Ife., 2023) Olumuyiwa, Fowole Ashaolu
    This study examined the distributional issues in resource productivity and farm incomes in Kwara State, through the economic analysis of agricultural production, conditional upon farm size. Specific objectives were to examine the existing farm size patterns and identify factors which determine the distribution of farms in the state, analyze the impacts of the existing farm size patterns on resource productivity and farm incomes, investigate the cost-size relationships for grain-crop farms under irrigated (Fadama) and rainfed agriculture, and determine the optimal farm sizes and forecast the distribution of future farms for the small, medium and large farm size groups.
