Item Effect of workdays lost to presumptive malaria on food crop production in rural south west Nigeria(2019-09-23) Adekanye J.O.; Adepoju A.O.; Adeoti A. I.Malaria is a major public health problem in Nigeria, having negative effect on economic livelihood of farming households. Therefore, this study examined the effect of workdays lost to presumptive malaria on food crop production in rural South west Nigeria. A four-stage sampling technique was used to randomly select 395 food crop farming households from Oyo and Osun states based on probability proportionate to size. Structured questionnaire was employed in collecting primary data used in the study. Data were analysed using descriptive statistics and ordinary least square regression model at α0.05. Age of households’ head was 56.41±9.34 years. Male respondents were 88.6%, household size was 7±2 persons and 37.0% had no formal education. Only 45.1%, 24.6%, 37.2% and 7.1% had access to extension services, credit facilities, electricity and mosquito nets, respectively. In a year, the average number of presumptive malaria episodes per household was 17.49± 4.28. Workdays lost to malaria was 73.49±23.87, out of which 69.8% and 30.2% was due to sickness and caregiving, respectively. Household size (β=-1.00), hired labour (β=-0.25) and workdays lost to presumptive malaria (β=-0.12) reduced per capita food crop production while farm size (β= 0.42), fertilizer (β=0.43), herbicides used (β=0.15) and planting materials (β=0.11) increased per capita food crop production. Workdays lost to presumptive malaria had negative influence on household food crop production. Therefore, people in the study area should be encouraged to make proper use of malaria preventive measures, such as mosquito nets, so as to reduce frequency of mosquito bites and malaria attacks. Medication that can reduce the days of incapacitation should be intensified and made available to farmers at affordable prices in order to improve the quality of life and productivity of farming households. Also health education should form a core of educational and extension service delivery to the farmers especially in the rural areas where majority are into farming as means of livelihood.Item Contribution of non-timber forest products (ntfps) utilization to the well-being of women: evidence from nigeria(2021-10-02) Adepoju, A.O.; Adewale,A.A.; Jayeola, O.B.This paper assessed the contribution of NTFPs to the well-being of women living in Ewekoro Local Government Area of Ogun State, Nigeria. Logistic regression and Ordered Logistic regression models were used to assess the contribution of NTFPs to the well-being of 120 women in the study area. The mean age, monthly household income, distance of homestead to forest and homestead to the nearest market were 47 years, $144.4, 2.0km and 1.8km respectively while 70.5% of the women used NTFPs as food. The housing dimension had the highest index of 0.537 while the overall index of 0.491 indicates a moderate level of well-being for respondents. NTFPs utilization significantly increased with household income and primary occupation but decreased with increasing age, level of education, distance from homestead to forests, distance to the nearest market and access to credit. Women’s well-being increased with utilization of NFTPs, being married, distance from homestead to the nearest market and access to credit but decreased with the distance of homestead to the forest, association membership and income. It is recommended that agricultural advisory and extension services in terms of NTFPs collection and utilization be provided; unconditional cash transfers and other consumption smoothening aids should be provided; necessary road networks should be rehabilitated or constructed, this will enhance NTFPs utilization; credit access should be provided for rural women, and rural women should be mobilized to form and/or join associations. Given that, NTFPs utilization contributes to the well-being of women, policies and programs that will enhance women’s utilization of NTFPs should be put in placeItem Effects of pre-storage treatments on sprouting and nutritional quality of ginger (zingiberofficinalerosc) rhizomes in different storage periods(International Peer Reviewed Journal and book Publishing, 2016) Olaniyi, J. O.; Olusoga, S.; Babatola, L. A.; Atanda, T. T.Purpose: Ginger rhizomes are highly susceptible to damage during postharvest storage due to soil borne pathogenic disorder. Experiments were conducted to evaluate the effects of prestorage treatments required for sprouting and maintaining the quality of ginger plant in different storage periods at the Teaching and Research Farm, Ladoke Akintola University of Technology, Ogbomoso. Method: The rhizomes were treated with four different pre-storage treatments viz.,control, hydrated lime, - Mancozeb, and 100ml of Trichodermaharzianum solution at different storage periods of one, two and three months. The experiment was arranged in a complete randomized designand laid out in a randomized complete block design with three replicates. Data were collected on percentage sprouting, plant height, number of leaves, leaf area and nutritional quality of ginger rhizomes. Data were subjected to analysis of variance using Statistical Analysis System Software (SAS, 2005). Differences among treatment means were compared using Least Significance Difference (LSD) at 5% probability level. Results: The storage periods significantly (P≤0.05) influenced the percentage sprouting andgrowth parametersof ginger at various sampling period. Highest growth of 9.05cm was recorded from ginger plant stored for three months while the least value of 6.94cm was obtained from rhizomes stored for one month. The pre-storage treatments significantly (P≤0.05) influenced the percentage sprouting, weight loss and growth parameters of ginger at various sampling period. Highest percentage sprouting (94.3%) was recorded from rhizomes treated with 100 ml Trichodermaharzianim solution followed by rhizomes treated with hydrated lime (88.3 %) while lowest percentage sprouting (61.5 %) were recorded from control. Highest percentage weight loss of 46.3% was recorded from control followed by hydrated lime (35.58 %) while the lowest percentage weight loss of 33.93 % was recorded from 100 ml Trichodermaharzianim solution. Conclusions: In conclusion, rhizomes treated with Trichodermaharzianim solution for a period of three months before planting produced better sprouting and enhanced the growth quality of ginger on the fieldItem DETERMINANTS OF AGRICULTURAL RISK MANAGEMENT BEHAVIOUR OF CROP FARMERS IN NIGERIA(2014-12) OLAJIDE, F.OAgricultural risks constitute a fundamental challenge in Nigeria, leading to low productivity among farmers. Farmers risk management behaviour determines the extent to which they overcome risk types. Information on crop farmers’ risk management behaviour in Nigeria is however scanty. Therefore determinants of agricultural risk management behaviour of crop farmers in Nigeria were investigated. Multistage sampling technique was used. Of the agro-ecological zones, Coastal, Rainforest and Guinea savannah were randomly selected. Thereafter, 10% of the states in the zones (Lagos, Osun and Niger) and 10% of the Local Governments Areas (LGAs) in the states were selected. Two communities were selected from each of the LGAs and 15% of crop farmers were chosen in the selected communities to give 323 crop farmers. Interview schedule was used to collect data on respondents’ risks types, risk exposure levels and risk management strategies. Indices were used to categorise farmers on their risk types (production, marketing, financial and social) and risk behaviour (superior, active, di-function, mono-function and part-time risk managers). Data were analysed using descriptive statistics, chi-square, Pearson Product Moment Correlation, ANOVA and multinomial logistic regression at p= 0.05. Most (90.0%) respondents were males, married (89.7%), and had at least primary school education (62.3%) with farm sizes of less than 5 hectares (72.3%). Age and years of farming experience were 53.2±10.5 and 28.3±12.1 years respectively. Majority (94.2%) identified inadequate cash-flow, pests and diseases (91.3%), ill-health of farmer/farm employee (89.0%) and volatility in output price (85.5%) as types of agricultural risks. Respondents were more vulnerable to production (9.85) and financial (9.84) risks. Majority (81.3%) were moderately or highly exposed to agricultural risks. Risk management strategies highly utilised were reducing leverage (2.94), maintaining good relations with contracting partners (2.73), use of fertilizers (2.65) and use of improved seedlings (2.57), while 73.9% of the farmers that had crop insurance coverage affirmed that it was effective in managing risks. Use of risk management strategies was low for 47.1%, with marketing strategies being the least (1.17) utilised. Superior agricultural risk managers accounted for 14.2%; active (26.8%); di-function (33.2%); mono-function (21.9%) and part-timers (3.9%), with the coastal zone having the highest percentage of superior (19.0%) and active (43.1%) risk managers. There were significant relationships between level of risk management and each of sex, marital status, educational level and farm size. While the Guinea savannah zone had the highest level (259.58) of agricultural risk exposure, the coastal zone had the highest level (75.89) of agricultural risk management. Significant predictors of agricultural risk management behaviour were farm size, organization membership and risk exposure level for mono-function and active managers. Di-function and superior managers were significantly predicted by farm size and risk exposure level respectively. Crop farmers in the zones encountered more of production and financial risks and lacked adequate risk management strategies. Their low level of insurance coverage indicated that factors other than awareness determined participation in insurance. Crop farmers should utilise more risk management strategies in order to reduce their risk exposure levels.Item Comparative assessment of the changing pattern of land cover along the Southwestern coast of Nigeria using GIS and remote sensing techniques(Elsevier, 2022) Fashae, O. A.; Tijani, M. N.; Adekoya, A. E.; Tijani, S.A.; Adagbasa, E. G.; Aladejana, J. A.The changing pattern of land cover is increasingly becoming of global concern in the sustainable management of environmental resources. Different facets of the natural ecosystem continue witnessing devastation orchestrated by rapid population growth and urban expansion in the face of climate change. This study examined the contribution of human’s to the global environmental change by assessing the dynamics of land cover between 1984 and 2017 while predicting the future extent of land cover pattern for 2047 at the Epe and Igbokoda areas on the coast of southwestern Nigeria. Landsat Thematic Mapper (TM), Enhanced Thematic Mapper Plus (ETM + ), and Operational Land Imager (OLI) imageries of 1984, 2002, and 2017 respectively were acquired from the USGS to analyse the land cover changes. Supervised classification was done using the maximum likelihood classifier of Terrset version 18.31. The Change Demand Modelling of Land Change Modeller (LCM) in Terrset integrates the Markov chain for future predictions for 2047. The Epe area which typifies a rapidly urbanizing coastal environment recorded an 84.6% increase in built-up area extent between 1984 and 2017, while the built-up area of the Igbokoda area increased by 103.8% for the same period. This increment corresponds to a decrease in the spatial extent of the forested wetlands with an increase in water bodies. Expansion of water body extents indicates the interaction between the elements of climate change such as incessant flooding and anthropogenic activities like deforestation, urban expansion through sand mining and dredging. Future prediction into 2047 connotes further worsening of the situation. Therefore, solution-based sustainable coastal management practices are recommended to salvage the impoverishing coastal ecosystems from further impairment.Item Determinants of utilisation of university of Ibadan agricultural research outputs among farmers in Oyo and Osun states, Nigeria(2021) Okanlawon, O. M.; Tijani, S. A.; Oguntade, M. I.The study assessed determinants of farmers’ utilisation of University of Ibadan (UI) Agricultural Research Outputs (AROs) in Oyo and Osun States, Nigeria. A multi-stage sampling procedure was used to select 176 beneficiaries of AROs in the study area. Focus Group Discussion and interview schedule were used for data collection on respondents’ socio-economic characteristics, knowledge, utilisation level and determinants of utilisation of UI AROs. Data was analysed using descriptive and inferential statistics like Chi square, PPMC, and multiple regression. AROs considered for the study were use of neem (Azadirachta indica) extract for pest management, rice-fish-poultry integrated farming system, processing of moringa oleifera powder and ruminant feed block meal pattern. Results reveal that respondents’ mean age household size were 40.05±35.48 years of 4.04±1.25 persons respectively. Respondents had mean farming experience of 7.92±5.26 years. The most utilised source of labour was family (63.0%) with mean farm size of 1.56±0.93 acres. Respondents’ knowledge (67.0%), and utilisation (55.7%) of UI AROs were high for innovations disseminated. Respondents’ marital status (χ2=5.99), sex (χ2=3.92), level of education (χ2=30.69); age (r=0.23) and income (r=0.79) were significantly related to UI AROs utilisation. Respondents’ knowledge (r=0.32) and benefits derived (r=0.80) were significantly related to utilisation of UI AROs. The determinants of utilisation of the AROs included educational qualification (β = 0.462), years of farming or processing experience (β=0.27), scale of production (β=0.33) and knowledge on utilisation (β=0.45). The study recommends that farmers be encouraged to improve on their level of education for better utilisation of disseminated agricultural research outputs.Item Determinants of vegetable women farmers’ economic security in Boke region, Guinea(2021-06) Tijani, S. A.Vegetable production had been a major source of livelihood among women in Guinea. This study therefore, assessed the determinants of vegetable women farmers’ economic security in the Boke region of Guinea. A multi-stage sampling procedure was used to select 180 respondents for the study. Data was elicited from the respondents with the aid of interview schedule and analysed using descriptive and inferential statistics. The results revealed that average household and farm size cultivated respectively were 8.54±3.55 persons and 1.17±0.62 ha. Personal land (71.7%), household (97.2%) and hired labourers (84.4%) were used by respondents. Almost all (95.0%) relied on personal savings for the finance of vegetable farming. Prominent constraints against vegetable production were inability to access credit at banks (x̅=1.87), lack of storage (x̅=1.87) and processing (x̅=1.86) facility. Vegetable enterprise was not profitable for 53.3% of respondents. Income from vegetable farming was neither adequate (99.4%) nor stable (100.0%). Average annual expenditure ($4,664.92±1723.75) was higher than annual income ($704.49±1,379.98) Almost all the respondents were economically insecure (98.9%) thus unsustainable livelihood and inability to cope with emergencies. Significant predictors of economic security among respondents were household size(β=-0.229), use of personal land (β=-0.188), use of rented or lease land (β=-0.205), use of family land (β=-0.142), use of family/ hired labour (β=0.159), annual income (vegetable) (β=0.596) and the number of vegetables grown (β =-0.150). The study recommends that farmers be encouraged to form cooperatives in order to facilitate access to credit facilities, need for the establishment of cottage industries and promotion of value addition.Item Training needs of communication officers of agricultural and rural development agencies for entertainment-education script writing in Southwestern Nigeria(Institute of Agricultural Research and Training, Obafemi Awolowo University, 2020) Olajide, B. R.; Tijani, S. A.; Ojomuyide, T. O.The use of Entertainment-Education (EE) for information dissemination in agricultural extension agencies requires that key frontline professionals are trained in EE script writing, therefore the training needs of communication officers in EE script writing was probed in this study. All (42) communication officers of agricultural development agencies in the study area were interviewed. Data were collected using questionnaire to elicit information on communication officers' socioeconomic characteristics, awareness of the components of EE script writing, perception of integration of script writing skills for agricultural information dissemination and training needs for EE script writing in agricultural information dissemination. Data were analysed using frequencies, percentages and means. Results indicate that respondents' mean age was 43.0±6.8 years, 38.1% had Bachelor’s Degree and were mostly male (64.3%). Most respondents were aware of the components and sub-components of EE scriptwriting, 52.4% had favourable disposition to the concept and had most training need on message, character and plot components. The study concludes that communication officers are abreast of the components and subcomponents of EE scriptwriting and are favourably disposed to the concept of EE script writing. Training on EE script writing for communication officers of agricultural development agencies should focus on message, character and plot components.Item Characteristics of shea butter processing in Niger State, Nigeria(2020-10) Tijani, S. A.; Sanusi, M. K.The study examined the characteristics of Shea Butter processing and factors associated with the output in Niger states, Nigeria. Two stage sampling procedure was used to select 315 respondents. Interview schedule was used in data collection. Data collected were analysed with percentages, Chi-square, the Pearson Product Moment Coefficient (PPMC) and simple regression model at α 0.05. The result revealed that the majority (80.6%) of the respondents used semi-mechanised method in processing Shea butter. The average unit price of Shea butter was N476.07K per Kilogramme, while the average income was N439,650.37K per annum. Processors had low level of accessibility to modern processing technologies (66.2%) and more than half (64.8%) of the processors were producing at low level. Lack of credit facilities and high cost of processing equipment were identified as severe constraint to Shea butter processing. There were significant relationship between level of education (χ²=11.18, p≤0.05), level of engagement (χ²=8.71, p≤0.05), income (r=0.819, p≤0.05) and accessibility to modern Shea butter processing technologies (r=0.164, p≤0.05) with level of Shea butter processing output. The major determinants of Shea butter processing output were income, household size, unit price and accessibility to modern processing technologies. Financial institutions should provide soft loans to Shea butter processors to acquire inputs and equipment. Similarly, government agencies should provide Shea butter processing equipment to the processors to improve access to the technologies that could lead to increase Shea butter production in Niger state.Item Effects of small scale irrigation on women farmers’ well-being status in Sikasso region of Mali(2020-10) Tijani, S. A.; Kone, D. M.This study examined effects of small scale irrigation on women farmers’ well-being status in Sikasso Region of Mali. A multi-stage sampling procedure was used to select 160 respondents (user and non-users) while data were collected using interview schedules and analysed using percentages, mean, standard deviation and t-test. Major constraints facing users are crop damage (x̅ =2.68), unavailability of input (x̅ =2.41) and inadequate credit facility (x̅ =2.15). Sixty percent, 98.8%, 85.0%, 85.0% of users have higher level of material, economic, mental and social well-being, respectively compared to 25%, 0.0%, 68.8% and 35.0% of non-users with similar status. The overall wellbeing of 73.8% of users were better-off compared to 11.3% of non-users. A significant difference (t= 11.110) existed in the wellbeing status of users and non-users. Utilisation of small-scale irrigation systems had positive effects on the mental, social, economic and material wellbeing of the users. There is need to extend small scale irrigation to non-users.
