Acceptability of egg powder among nursing mothers in rural areas of Ijebu North local government area of Ogun State, Nigeria
(2018) Tijani, S. A.
Eggs are among the most nutritious foods, cheapest source of protein, vitamins and minerals. However, fresh egg is fragile and its quality deteriorates easily. Egg powder adds consistent performance to the list of attributes of the commodity hence the need to evaluate the acceptability of egg powder among nursing mothers as a source of protein. The study was carried out in rural areas of Ijebu North Local Government Area of Ogun State. Random sampling technique was used to select 120 respondents across five maternity health centres. Interview schedule was used to collect data. Data were analysed using both descriptive and inferential statistics at α0.05. Findings revealed that 62.5% of the respondents had low level of awareness about egg powder, more than half (55.8%) had unfavourable disposition towards egg powder, resulting in 60.0% of them having low acceptability for its use. Non-availability of egg powder (50.8%) and lack of information on egg powder (50.0%) were major constraints to egg powder consumption in the study area. Significant relationship existed between respondents’ income (χ2 = 0.184), level of education (χ2 = 0.233), awareness (r = 0.229), perception of egg powder (r = 0.246) and the level of acceptability of egg powder. There was a low level of egg powder acceptability in the study area. Hence, there is a need to create awareness on the nutritive value of egg powder in the study area.
Access to credit and value additions to some non-timber forest products in Egbeda Local Government Area, Nigeria
(2012) Azeez, I. O; Falade, K.O
The capacity to promote sustainable use of Non-Timber Forest Products (NTFPs) and facilitate increased financial benefits to local users as incentives for forest conservation is low due to neglect by governments particularly in Nigeria. Such capacity is however imperative to stemming rural poverty and can be enhanced by incorporating NTFP collection and commercialization research into forest management development programs. But sustainable production and conservation of forest products is influenced by a number of factors, largely socioeconomic and institutional in nature. Men and women also play different roles in the collection and utilization of NTFPs. This paper reports collection and sales of NTFPs against some socioeconomic background of identified collectors in Egbeda Local Government Area (LGA), Oyo state, Nigeria. Purposive simple random sampling was used to select respondents from the study population using the medium of the Egbeda Farmers Association of Nigeria (EFAN). Egbeda LGA has 10 cell groups of EFAN and twelve (12) farmers were selected from each of the cell group. A total of 120 sets of structured questionnaire were used to document demographic information, involvement in NTFPs business and access to credit facilities among respondents. Oral interview were also conducted to know if they engage in the NTFPs business as a primary occupation or secondary occupation, the type of NTFPs specialized in, their sources, number of gathering trips per week, and the amount made from the sales of the NTFPs. The data collected was analyzed using descriptive and inferential statistics. More than half (53.3%) of the respondents involved in the NTFPs business in the study area was of the male gender and 62.5% had secondary education. Majority of the respondent (88.2%) engaged in NTFPs gathering as a secondary occupation. Their access to credit facilities was low. The amount made from sales without credit facilities is reasonable. Inadequate funding, lack of credit facilities, inadequate information about how to market their products and its neglect by government were identified as a major constraints to sustainable collection and use of NTFPs. NTFPs would contribute more to livelihood in the study area, provided access to credit can be facilitated.
Access to production information among citrus farmers in Atisbo Local Government Area of Oyo State
(Agricultural Extension Society of Nigeria, 2007) Eniola, P. O.; Fawole, O. P.
The study was conducted to determine the level of awareness, access and utilization of sixteen, Citrus production by citrus farmers in ATISBO Local Government Area of Oyo State. Structured interview schedule were administered on sixty citrus farmers who were purposively selected from six communities. Descriptive statistics such as frequency distribution, percentage and rating were used to analyse the data. Ninety eight point three (98.3%) of the respondents were male and 85 percent (85%) were married. The main source of information was village extension agents and contact farmers as indicated by 46.7 percent and 41.7 percent of respondents. Sixty eight percent of the farmers experience low yield of citrus. Level of information awareness, access and utilization of citrus farm practices was low. That is 63.3, 58.86 and 50 percent of the respondents had low scores respectively. The extension agents have been encouraged to release to farmers necessary information that could lead to high citrus production in the area.
Acute toxicity of ethanol extracts of cocoa bean shell on sarotherodon galilaeus juveniles
(Medwell Journals, 2008) Olaifa, F. E.; Hamzat, R. A.; Oyetoyan, O. O
An acute toxicity test of ethanol extract of cocoa bean shell (CBS), a by-product of cocoa processing was conducted on 250 Sarotherodon gallilaeus juveniles for 96 h. There were 5 treatments and one control with each having 3 replicates. The treatments were prepared as 10,000, 7500, 4167, 2315, 1286 and 0 mg L-1 (control). The aim of the experiment was to study the toxic effects of Ethanol extract of CBS. While, the control experiment produced no mortalities and adverse histopathological responses, there were reactions to the presence of CBS extract in all the treatments which included restlessness and mortality. The lethal concentrations at which fifty percent of the test population died (LC 50) obtained using the logarithm method were 7943, 5012 and 6310 mg L-1 for replicates 1, 2 and 3, respectively while the probit method gave 5878, 4865, 6103 mg L-1 for replicates 1, 2 and 3, respectively. Histopathological examination of control fish showed no lesions on all tissues examined. However, marked changes were observed in the liver in form of degenerative hepatocytes, multifocal aggregation of haemosiderin laden macrophages; in the gills as shortening of gill filaments and in the brain as spongiosis of white cerebral matter of fish subjected to various concentrations of CBS extract. It was concluded that ethanol CBS extract possessed piscicidal properties on S. gallilaeus which could be useful in culling stunted and unwanted fish populations from ponds before stocking
Agricultural productivity under taungya and non-taungya land-use options: a case study of Vandeikya Local Government area, Benue State, Nigeria
(International Formulae Group, 2011) Adegeye, A. O.; Jimoh, S. O.; Agera, S. I.
Taungya farming is a special arrangement between the forestry department and farmers, which combines the production of both arable and forest tree crops simultaneously on a piece of land. The practice was adopted in Vandeikya Local Government area of Benue State Nigeria, in mid 1950s up to 2000. This study evaluated the method as an option for food and fiber production compared to the traditional farming and forest management practices. Using Stratified random sampling, two sets of questionnaire were used to appraise the productivity of some arable crops and forest regeneration under taungya and non-taungya cultural practices. The yields of arable crops were significantly higher under taungya farming that in non-taungya plots in the study area. There was however no significant difference in the total forest area regenerated under the two landuse systems. The apparent land hunger among farmers is a favourable factor for adoption of taungya as a land use option in the study area. There is need to adopt multi-species planting approach in future programmes. Also, the land tenure system which limits access to land by strangers needs to be reviewed and greaterawareness on the programme needs to be generated among the farmers and forestry staff alike.
Agro-Industrial by-products and farm wastes for poultry production in Nigeria: challenges and opportunities
(Faculty of Agriculture and Forestry, Univcrsity of Ibadan, 2011-06) Abu, O. A.; Iyayi, E. A.; Tewe, O. O.
The poultry industry in Nigeria requires up Io ninety per cent of the total commercially produced feeds in Nigeria. Conventionally, maize is the major source of energy in poultry feeds in Nigeria, while soybean, groundnut cake and fish meal are sources of protein. Poultry farmers often use alternative feed ingredients whenever the prices of the conventional feed ingredients increase beyond realization of profit. Agro-industrial by-products (AlBs) are mostly cereal and oil seed processing by-products but when poorly stored agro-industrial by-products often go mouldy necessitating the use of toxin binders. The substituability of cassava for maize is almost unity but for the additional processing effort that is required for cassava. Hatchety wastes (eggshell, culled eggs, poorly formed chicks) and slaughter houses (blood, bones, rumen scrapping, and feathers) are of animal origin potentially available for inclusion in feed. The use of animal by-products for componding feeds is however becoming less acceptable. Crop wastes that have potential for use in poultry feeding are cassava leaves and also leaves from other crops. The leaves can be good sources of leaf protein when harnessed. Exogenous enzymes results in cost reduction and improved animal performance. Whereas several of these by-products are available for inclusion in poultry feeds either as energy or protein alternatives, wide Variation in their nutritional compositions and lower quality compared to the conventional feedstuffs create a Situation of challenge in their use. Nevertheless, their potential can be harnessed by guided inclusion levels, further processing, supplementation with exogenous enzymes or a combination of all three factors. In conclusion, to complementing the use of alternatives feed ingredients, the poultry farmer should also be encouraged to increase the efficiency of production by considering proper manipulation of feed, application of appropriate housing System, the use of feed additives among others.
AGROFORESTRY PRACTICES AND THEIR POTENTIAL CONTRIBUTIONS TO SOIL FERTILITY AND FOOD PRODUCTION IN KATSINA STATE, NIGERIA
(2011-10) AMONUM, JOSEPH IGBA
Unsustainable forest land use practices have resulted in land degradation in the northern part of Nigeria leading to low crop yield. Agroforestry is a viable option for reversing dwindling crop yields through proper soil management practices. There is notably no sufficient published information on the contributions of agroforestry to food production in Katsina State. The practices of agroforestry and its potential to slow down the pace of soil degradation and boost food production in Katsina State was therefore investigated. Multistage stratified sampling was used to select respondents for the study. Three Local Government Areas (LGAs) were randomly selected from each of the agro-ecological zones (Sahel, Sudan and Guinea) of Katsina State. Within each of the selected LGAs, one community was randomly selected and forty respondents were randomly sampled from each community. Using structured questionnaire, information was sought on the socio-economic and demographic characteristics of respondents, Agroforestry Practices (AP), attitude to AP, information sources on AP and AP perceived benefits. Chemical characteristics of soil samples from agroforestry and non-agroforestry plots of respondents in the three zones were also determined using standard methods. Data were analysed using descriptive statistics, Chi-square and ANOVA at p = 0.05. Most of the respondents (96.3%) were married, 82.5% were male and 50.0% were between 30 and 49 years of age. Their primary occupation was mostly farming (66.1%) while modal annual farm size was 1 – 2 hectares. Means of land acquisition was more by inheritance (50.8%) and 33.1% of the respondents made an annual income of between N30,000.00 – 40,000.00. The major farm enterprises were food crop production (74.1%), livestock (5.2%), tree crops (0.6%) and various combinations of these (19.0%). Multipurpose trees on farmland (79.2±11.1%), windbreaks (50.0±13.3%), woodlots (49.7±3.9%), improved fallow in shifting cultivation (32.2±26.3%) and home gardens (24.7±6.9%) were the common AP by the respondents. Benefits of AP to the respondents included preservation of the environment (98.5%), provision of fruits and leaves (98.3%), improvement of soil fertility (97.5%), erosion control (97.5%), improvement of farmers income (95.8%) and provision of fodder (92.7%). Also, 93.9% of the respondents reported increased yield of arable crops from a mixed tree and arable crop farm. Majority of the respondents (70.3%) identified scanty rainfall, land shortage and inadequate labour as problems while 12.8%, 4.7% and 4.4% respectively identified each of the problems as limiting AP. Although significant variation was observed in AP in the zones, sources of information significantly impacted adoption of AP in Sahel and Sudan but not in Guinea savanna zone. Significant variation was observed in soil pH, total nitrogen, Mg2+, K+ and Na+ between agro-forestry and non agro-forestry plots with soil nutrient and organic matter content skewing in favour of agroforestry plots. UNIVERSITY OF IBADAN LIBRARY iii Agroforestry practices enrich the soil with important nutrients and prevent soil erosion. The adoption of multipurpose trees on farmland in Katsina state will help in preventing environmental degradation, desertification and enhance food crop production.

Allelopathic effect of pentaclethra macrophylla benth. leaf extracts on germination and seedling growth of maize and okra
(2020) Ogbu, J.U.; Awodoyin, R.O.; Olubode, O.S.
Pentaclethra macrophylla Benth. is an indigenous leguminous tree of southern Nigeria's agroecosystems, whose seeds are used as spices; however, its allelopathy potential is not understood. Therefore, this study was aimed at investigating P. macrophylla allelopathic effects on germination and seedling growth of maize and okra. Materials and Methods: Allelopathic effects of Aqueous Leaf Extracts (ALE) of P. macrophylla at 0 (control), 10, 20, 40 and 80% concentrations on maize (n = 200) and okra (n = 200) seed germination and seedling growth were assessed in laboratory and screen house nursery. Total germination (%) for both crops was determined at one Week After Sowing (WAS); while Number of Leaves (NL), Plant Height(PH) (cm), Root Length (RL) (cm) and Dry Weight (DW) (g) were evaluated at 8 WAS. Experimental design used in the study was completely randomized design. Data were analyzed using descriptive statistics and ANOVA at a0.05. Results: Above 90.0% germination was recorded for maize in all the ALE concentrations, while for okra ALE-10 gave significantly highest germination (90.0±8.7%) and ALE-80 gave least (42.5±26.3%). Maize and okra seedlings given ALE-40 had highest NL, PH and DW;* while ALE-0 (control) had least values in PH and DW, respectively. Control had highest RL in both crops. The ALE-10 gave least RL in maize and ALE-20 gave least RL in okra. Conclusion: Pentaclethra macrophylla aqueous leaf extract at 10% enhanced germination, while 40% concentration encouraged dry matter accumulation and height in maize and okra seedlings.
Allelopathic effects of aqueous extracts of olax subscorpioidea oliv. on seed germination and growth of okra (abelmoschus esculentus (l.) moench) in Ibadan, Nigeria
(2022) Ayoola, D.O.; Olubode, O.S.
Allelochemicals are being explored as environmentally friendly options in weed management and crop yield improvement as opposed to use of synthetic pesticides which have serious environmental damages. Allelopathic effects of aqueous extracts of different parts of Olax subscorpioidea on Okra seed germination in Petri-dish bioassays and okra performance in pot experiment were conducted in the Department of Crop Protection and Environmental Biology, University of Ibadan using a complete randomized design (CRD) and with treatments replicated five times. Ten okra seeds in three replicates were treated in separate petri-dishes with 2 ml water extracts of stem, leaf, fruit, bark and root of Olax subscorpioidea, and 2 ml distilled water (control) in two trials. Pot trials was carried out using okra seedlings with treated with 100 ml extracts at seven days intervals. Data were collected on number of germinated seeds daily and lengths of five randomly selected plumules and radicles at 7 days after sowing (DAS). Number of leaves, plant height, root and shoot dry weight of seedlings were also measured using standard methods. Data were analyzed by analysis of variance. Statistically significant (P<0.05) means were separated using Duncan’s Multiple Range Test. Leaf extract had the highest concentrations of phenolic, flavonoid and saponin compounds compared, while the stem extract had the least metabolite concentrations. Leaf extracts exerted highest inhibition on okra germination at 2 and 7 DAS in the first trial and at 7 DAS in the second trial compared to the bark, stem, root and fruit extracts of Olax subscorpioidea. The seedling growth and yield parameters in treatment extracts were better than control. In conclusion, Olax subscorpioidea has allelopathic potential with effects on germination and seedling growth of okra. It can be used as an alternative bioherbicide. Its production and agricultural potentials should be promoted.
Allelopathic potential of some biocontrol agents for the control of fungal rot of yellow yam (Dioscorea cayenensis Lam)
(2015) Dania, V. O; Fadina, O.O; Ayodele, M..; Kumar, P. L.
The adverse effects of synthetic pesticides on human health and natural ecosystem necessitate the need to explore natural mechanisms of disease control in plants. This study evaluated the allelopathic potential of five biocontrol agents: Trichoderma longibrachiatum, Trichoderma asperellum, Bacillus subtilis, Bacillus cereus and Pseudomonas fluorescens in the control of six fungal pathogens associated with tuber rot of Dioscorea cayenensis. Rotten tuber samples were randomly collected across three agro-ecological zones (AEZs): humid rainforest (HF), derived savanna (DS), and southern Guinea savanna (SGS) in Nigeria. Biocontrol agents were isolated from the yam rhizosphere using the serial dilution method; the agar paring method was used for the in vivo trials. The destruction sampling method was used to evaluate rot control by the antagonists in vivo. Aspergillus niger had the highest incidence of 64.71% across the HF, 52.08% across the DS, and 41.98% across the SGS. B. subtilis had the highest inhibitory zone of 16.7+0.05% when paired with A. niger, 15.4+ 0.01% with Lasiodiplodia theobromate, 14.0 + 0.33% with Penicillium oxalicum, 7.1 + 0.14% when paired with Rhizoctonia solani: 17.1 + 0.11% with Sclerotium rolfisii, and 10.3 + 0.94% with Fusarium oxysporum. All biocontrol agents significantly (P=0.05) reduced rot development of the test pathogens relative to the control in the in vivo experiment. The establishment of a distant zone of inhibition, especially by the bacterial antagonist attests to the fact that they produced allelochemical substances. Therefore, further research is recommended to evaluate the biochemical composition of these microbial metabolites, their level of toxicity, and fate in the environment

Analysis of Edible Snail (Archachatina margtnata) Marketing in Ibadan Metropolis, Oyo State, Nigeria
(International journal of applied research and technology, 2012) Adenegan, K.O.; Bolaji-Olutunji, K.A.
The study examined the marketing efficiency, profitability and the factors contributing to the profitability of snail marketing in Oyo State Nigeria. Forty copies of questionnaires were administered in five major markets in Ibadan (Aleshinloye, Oje, Orita-merin, Bodija and Apata markets). Simple descriptive analyses such as percentage and frequency table were used to describe the socio-demographic characteristics of the respondents while multiple regression analysis was used to examine the determinants of profitability of snail marketing. It was discovered from the empirical result that 90% of the sellers were female while 10% were male. One hundred percent (100%) of the sellers were 20years of age and above, and have 10 or more years of experience, 37% had no formal education while 40% had primary education and 23% had secondary education. The average profit N24, 250 forms the Budgetary Analysis (Av.selling price -Av.cost price) while the marketing efficiency for different markets are 1.98, 1.54, 1.19, 1.25 and 1.60 for Aleshinloye, Oje, Oritamerin, Bodija and Apata respectively. Four regression functions (Linear Function, Semi log, double log and Exponential Function) were run to analyze the determinants of snail marketing profitability. The exponential function provided the best of fit equation because it has more significant variables, highest coefficient of multiple regression, R\0.66) and lowest DurbinWatson, DW (l.473).The marketing of Snail can be said to be profitable, efficient and sustainable. It can reduce poverty. Therefore, further research should be carried out to domesticate and rear more edible snails in Oyo State and Nigeria as a whole to get more supply of protein and calcium in our diets.
Analysis Of Genetic Structure Of Nigerian West African Dwarf Goats By Microsatellite Markers markers
(2015) Awobajo, O.K.; Salako, A.E.; Osaiyuwu, O.H.
Genetic variation at 12 microsatellite loci and population structure hypothesis was examined for West African Dwarf (WAD) goat populations found in four Southwestern states in Nigeria. Estimates of genetic variability such as effective number of alleles and gene diversities revealed substantial genetic variation frequently displayed by microsatellite markers. Number of alleles observed across the microsatellite loci varied from 6 to 17 with an overall mean of 10.75 ± 3.22. Average polymorphism across the studied loci and expected gene diversity in the population were 1.66 ± 0.49 and 0.72 ± 0.17, respectively. Population was observed to be significantly differentiated into different groups, and showed fairly high level of inbreeding (f = 0.95 ± 0.15) and global heterozygote deficit.

(2016) Awobajo, O.K.; Salako, A.E.; Akinyemi, M.O.; Osaiyuwu, O.H.
Genetic variation at three allozyme (Haemoglobin, Carbonic Anhydrase and Transferrin) loci and popula-tion structure hypothesis were examined for West African Dwarf goat populations in four Southwesternstate of Nigeria. One hundred and forty animals, twenty from each sampling area comprising Ijebu-Ode and Ado-Odo, (Ogun state), Ondo, (Ondo state), Ile–Ife, Osogbo and Iwo, (Osun state), and Ibadan,(Oyo state), were randomly selected. Estimates of genetic variability such as effective number of allelesand gene diversities revealed substantial genetic variation frequently displayed by allozyme markers. Numbers of alleles observed across the allozyme loci varied from 246 to 250 with an overall meanof 247.33 ± 2.31. Average polymorphism across the studied loci and expected gene diversity in thepopulation were 0.63 ± 0.09 and 0.44 ± 0.09, respectively. Population was observed to be significantlydifferentiated into different groups, and showed fairly high level of outbreeding (f = −0.16 ± 0.44) andexcess heterozygosity
Analysis of Growth Models of Japanese Quails (Coturnix Coturnix japonica) in Nigeria
(2017) Olaniyan, A.A.; Akinyemi, M.O.; Osaiyuwu, O.H.; Salako, A.E
This study, aimed at comparing the growth curve parameters and determining the best non linear model for Japanese quails was conducted at the Department of Animal Science, University of Ibadan, Ibadan. Two hundred and thirty-five (235) Japanese quails were purchased at day old from a reputable hatchery in Ibadan and reared in cages, after two weeks of brooding on deep litter. Body weights (g) were taken weekly from hatch till the birds were 25 weeks old. The average of the weekly body weights was fitted to four non-linear models, namely Gompertz, Logistic, Brody and Von Bertalanffy to define the growth pattern and examine the existence of differences in the growth pattern described by the models. Models were compared using Coefficients of determination (R2), Mean square error (MSE), size of Residual standard deviation (RSD), Akaike’s information criteria (AIC) and Percentage forecast error. The R2 values were high for all models: 0.980, 0.979, 0.973 and 0.973 for Von Bertalanffy, Gompertz, Logistic and Brody, respectively. The Mean square error and Akaike’s information criteria values were 65.744 and 107.449; 64.685 and 107.043; 51.363 and 101.277; 49.731 and 100.470 for the Logistic, Brody, Gompertz and Von Bertalanffy models, respectively. Residual standard deviations were 8.979, 8.539, 7.847 and 7.832 with corresponding Percentage forecast error (PCFE) values of 16.315, 11.523, 12.948 and 13.687 for the Brody, Logistic, Gompertz and Von Bertalanffy models respectively. The Von Bertalanffy model was the most suitable for explaining the growth of the Japanese quails based on these goodness of fit criteria: The highest R2 (0.980), lowest Mean square error (49.731), Residual standard deviation (7.832) and Akaike’s information criteria (100.470)
ANALYSIS OF INDIGENOUS PRACTICES OF SMALL-SCALE PLANTAIN FARMERS FOR APPROPRIATE ALLEY FARMING TECHNOLOGY IN OYO STATE, NIGERIA
(1992-10) ADEKUNLE, O. A.
The limitations of conventional technology development gave birth to Farming Systems Research perspective which look at farming practices from a holistic view. This however has innate flaws in its implementation. Recent emphasis therefore is strengthening the need to appreciate a hitherto neglected indigenous knowledge systems. This indigenous knowledge for instance, has been influencing the indigenous practices associated with small-scale plantain production. Before now Plantain has not received favourable attention despite its economic potentials in the Nigerian economy. This is the main reason for this investigation which described the indigenous practices in its production. It is with an intent to illustrate how Alley Farming Technology should be designed to blend with the indigenous practices of the small-scale plantain farmers. The inquiry was conducted in Irewole and Oranmiyan Local Government Areas (LGAs) of Oyo State (however, since the creation of new states in 1992, these LGAs have become part of Osun State). The objectives of the study were to: describe the socio-economic features of plantain farmers, ascertain their indigenous practices, identify constraints to production, examine their agricultural information sources and determine the impact of certain variables on indigenous practices. A mini-study (or field observation) was conducted on ten small-scale (volunteer- farmers less than 3 ha) plantain plots. The monitoring of these plots for about six months was to field-test certain concepts which were empirically investigated in the follow-up survey. The survey was an interview schedule administered to two hundred and seventy (270) small-scale plantain farmers selected through a multi-stage sampling technique in the two LGAs. Frequency analysis of information obtained from the ten plots indicated that the most common crops intercropped with plantain (26.2%) were cassava, cocoyam, maize and vegetables. Information from the questionnaire revealed that 91% of the respondents had no formal education. Though staking was a practice, recommended spacing and mulching of plantain was not favoured by 98% of the interviewees. Cutlass was frequently used by 99.3% in plantain operations. Male household heads determined planting plantain (99.3%), plots to be used (98.9%) while female household heads/wives of male household heads decided on plantain processing (78.5%), sales (89.6%) and cost of production (69.6%). Constraints to plantain production include declining soil fertility (98.5%), insufficient propagules (95.2%) and inadequate extension service (95.9%). Multipurpose trees (MPTs) known to plantain farmers were Cassia (98.1%) and Gliricidia (97.0%). At a priori P<.05, pearson correlation analysis indicated a significant and positive association between indigenous knowledge and intercropping of plantain (r = 0.25). Use of Radio as a source negatively correlated with staking (r=-0.51) and mulching of plantain (r = -0.23). Stepwise multivariate ^egression showed that 48% of the variation in indigenous intercropping of plantain was explained by six regressors; household size, social participation, alley farming awareness, extension drama method, farm service centres and poor community market prices for plantain. These findings have implications for the adoption of Alley Farming technology in the study area. There is a serious need to involve small-scale plantain farmers in alley species (MPTs) selection, establishment and management. A comprehensive extension educational programme is necessary to make plantain farmers more aware of the alley farming technology.

(2018) Osaiyuwu, O.H.; Akinyemi, M.O.; Akindele, O.D.; Ewuola, K.M.
The sex effect and interrelationship between body weight and six linear body measurements o fforty-five (15 bucks and 30 does) grasscutters aged between 12 and 24 months was assessedusing path analysis. Body weighty and linear body measurements: hind leg length, rump height, paunch girth, face width, mouth width, and total body length were measured for the male and female grass cutter. Results showed that there were significant differences (p<0.05) between the male and the female cane rats for all the parameters measured indicating sexual dimorphism in the cane rat All parameters assessed had highly significant (p<0.0001) and very strong positive correlation coefficients in both sexes. The path analysis indicated that in males, hindleg length (2.86;p<0.0001) had the highest direct effect on body weight, while rump height (-1.45; p<0.0001), had a negative direct effect In the female group, all the parameters evaluated had a nonsignificant, positive direct effect The hind leg length was observed to have the highest (0.29; p<0.0001) path coefficient while the mouth width (0.02; p<0.0001) had the least path coefficient It was concluded that sex had an effect on the interrelationship between body weight and linear body measurements in grasscutter.
