The study examined soil conservation techniques and its effect on productivity of arable crop farmers in Kogi state, Nigeria. Data were collected from 184 farmers using three stage sampling technique. Data analyses were carried out using descriptive statistics, Total Factor Productivity (TFP) and regression analysis. Result shows that the soil conservation technique prevalent in the area was application of inorganic fertilizer. About 36.4% of the sampled household heads have productivity value above average across all the soil conservation categories (productive). Result also reveals that age (-1.801), household size (-0.310) and access to credit (-0.056) impacted arable crop farmers negatively while alley cropping (0.357), crop rotation (0.380), application of inorganic fertilizer (0.503), mulching (0.560) and organic manure (0.373) positively impacted arable farmers’ productivity. The study concludes that soil conservation techniques are productivity enhancer. Promoting sustainable conservation techniques that are farm or farmer specific is recommended.
In this article, the Enterprise assessment across cassava peels value chain in Ogun State Nigeria is examined. Multistage sampling technique was used to select 180 cassava processors and marketers. Socio-economic data were obtained from respondents with the use of pre-tested questionnaires. Data were analysed using descriptive statistics, budgetary technique, Stochastic Frontier Analysis (SFA) and Student t-test. The study found that majority (84.3% and 52.8%) of processors of cassava peels and marketers were female. In addition, 60.2% of the processors and 51.4% of the marketers had secondary education. The value chain activities carried out by processors were transportation, drying and packaging while marketers transported, packaged and put the peels in storage for future sales. The SFA revealed that cost of labour (p<0.01) and quantity of fresh cassava peels (p<0.01) were the main determinants of output of dried cassava peels by the processors. The inefficiency model revealed that the efficiency of producing dried cassava peels increased with increase in age (p<0.01), credit access (p<0.01), household size (p<0.01) and membership of cooperative society (p<0.01). Furthermore, the cost function revealed that cost of sieving (p<0.05) and depreciation on capital item (p<0.01) increased the production cost of dried cassava peels. The mean technical, allocative and economic efficiency of producing dried cassava peels were estimated as 94%, 83% and 78% respectively. This study concluded that production of cassava peels is efficient and its trade is profitable. The study recommends that cassava processors and marketers should form cooperative groups to increase access to credit for higher output and trade of peels.
Throughout Africa, S. aethiopicum is very popular and plays a vital role in many human diets. Despite the fact that there are previous reports on yield characteristics and nutrition of the crop, there is a need to assess the crop for variations in mineral properties. This study aimed at determining the amount of genetic variability and level of heritability of agronomic and mineral contents of S. aethiopicum accessions. Fifteen accessions of S.aethiopicum were evaluated in an RBCD experimental design to generate data for use. Data were collected for agronomic, morphological and mineral contents. Data collected were subjected to ANOVA and the significant means were also separated using Duncan Multiple Range Test (DMRT) at 5% probability level. Variance component method was used to estimate phenotypic and genotypic variations as well as heritability. Significant differences were observed among accessions for the various morphological and mineral nutritional traits evaluated. High heritability estimates, Phenotypic and Genotypic variances were observed for mineral content and fruit yield. Genotypic and phenotypic variances ranged between 0.31 and 11078.85 for the agronomic traits. The hierarchical cluster analyses revealed five distinct clusters at similarity index of 85%. The first cluster included 6 accessions; the second included accessions NHS 101A, and OG 03; the third were NHS 104 and OG 01; the fourth included NHS 105; and the fifth included NHS 106, NHS 108, OS 02 and OS 03. Accessions OS 01 and OS 03 appear unique based on the traits for which the accessions were assessed.This study revealed that substantial variation exists within the accessions of S.aethiopicum evaluated, hence, it will help in breeding process of good quality genotypes for higher yields and mineral content.
Pig is one of the most consumed meat across the globe. However, its production is limited by high cost of feed ingredients. Hence, the search for alternative cheap feed ingredients without any loss to animal’s performance is on the increase. The influence of different protein sources and feed types (wet or dry) was investigated on the growth performance, haematology and serum biochemistry of weaned pigs. Weight gain and feed conversion ratio were higher for soybean and full-fat soya-based diets. Feed and water intake were not significantly different amongst treatments. Nature of feed did not influence weight gain, feed intake and feed conversion ratio. Groundnut cake meal may compare with soybean meal in pig’s diet, but it may have to be supplemented with lysine, methionine or fish meal.
The study assesses the impacts of Human-Wildlife conflicts in the surrounding villages in Old Oyo National Park (OONP), Nigeria. Two ranges out of the five ranges were used. Four villages were selected based on the distribution of primates and wildlife populations with each range producing two villages around Old Oyo National Park, were randomly selected for wildlife assessment. A total of 80 well-structured questionnaires were administered to the villagers with each getting 20 questionnaires respectively. Data collected were subjected to inferential and descriptive statistics. Result shows that among other socio demographic characteristics tested against the impact of Human –wildlife conflict in the park, educational level and religion show significant difference (p<0.05). the buffer zone around the park has been extensively encroached; this made most of the surrounding villages to the park fall within the average distance of 2.6km. about 79% of the villages make use of fire wood for their household cooking. Major animals that intrude farmlands in the study areas include monkey (24%), Grasscutter (11%), Cattle (19%), Gorilla (12%), Antelope (6%), Cane rat (5%) and Rabbit (3%). Some of the crops attacked by the wildlife animals include; tubers (24%), tubers and vegetable (7%), tubers and fruits (36%), tubers, vegetable and fruits (3%), vegetable (7%), fruits (3%). All the respondents (100%) rated the level of attack and damages to their crops as high.
This study assessed the management of indigenous livestock in Egba zone of Ogun State using one hundred and forty four farmers and twenty Village Extension Agents. Data were collected with interview schedule and questionnaire respectively. The study revealed that indigenous livestock farmers were of average age of 48 years, mostly (77.8%) native of these communities sampled and literate (63.2%), more female (58.3%) and they were not cosmopolite (83.3%). Poultry, sheep and goats are mostly kept by indigenous livestock farmers, followed by cattle and pig, snail and rabbit by a few farmers. Most (66.7%) farmers raised their livestock on free range while few provided feeding and housing for their animals. Local materials were used for feeding, housing, and ethno-veterinary care for animals. Livestock farmers earned an average of twenty one thousand seven hundred and fifty naira monthly from their animals. The materials livestock farmers used included pawpaw seeds for deworming, lime and sandpaper leaf to control lice, sulphur, lime and palm oil to control mange; Iyeye leaves [Spondia mombin] for treatment of diarrhea in ruminants. Communication methods used in the diffusion of ethno-veterinary practices were town criers, traditional songs and festivals, folk tales, use of signs and symbols, life dramas and face-to-face interpersonal media while the sources of information were extension agents, community leaders, fellow farmers, neighbours, livestock traders, and farmers` union. Most important information came from fellow farmers. Indigenous livestock farmers should be involved in research and extension planning and regular visits to farmers by village extension agents is recommended.
The research was carried was carried out to evaluate the chemical composition of the dominant grasses harvested from the natural pasture in selected villages in Ogun State, South-western Nigeria at different seasons. The study was carried out using a 4 × 6 factorial arrangement comprising four seasons (early rain, late rain, early dry and late dry) at six locations (Afami, Atokun, Ibooro, Ileniku, Ipaaya, and Okerori). Results showed that the crude protein (CP) content significantly (p<0.05) varied from 5.56 % for Okerori to 7.34 % for Ibooro and the grasses harvested at Afami had the highest (72.75 %) neutral detergent fibre (NDF) values with the least (68.75 %) value recorded for Okerori, while the acid detergent fibre (ADF) values ranged from 41.00 % for Atokun to 48.25 % for Okerori. Also, CP value as affected by the season ranged from 4.23 % for late rainy to 9.44 % for the early rainy season and NDF values from 67.33% for late dry to 72.33 % for late rainy season while the early dry season had the highest value (48.00 %) for ADF with the least value (40.33 %) was recorded for the early rainy season. The phosphorus (P) value was highest at Ipaaya (2.99 g/kg) with the least value observed at Okerori (1.62 g/kg). The value for calcium ranged from 2.55 g/kg at Afami to 6.59 g/kg at Okerori. The P value of grasses as affected by seasons ranged from 1.46 g/kg for early dry to 2.66 g/kg for early rainy seasons.
Nigerian indigenous chickens possess immunity from endemic diseases and have a better survival rate than commercial hybrid strains under local production conditions. FUNAAB Alpha chicken was developed by improving Nigerian indigenous chickens through crossbreeding and selection. This study compared the mitochondrial d-loop of FUNAAB Alpha and Nigerian indigenous chickens to check likely genetic erosion and loss of diversity in development of FUNAAB Alpha breed. Blood samples were collected from Nigerian indigenous (n=23) and FUNAAB Alpha (n=20) chickens sampled from farms and houses in Ogun state, Nigeria. The Hypervariable 1 (HV1) of the mitochondrial d-loop region was amplified and sequenced. Single nucleotide polymorphisms present in HV1 of chickens were identified using Clustal W. Genetic diversity of the region was determined using DnaSp v5 while selective forces acting on the chickens were predicted using HyPhy software implemented inside MEGA 6 software. Phylogenetic relationship among FUNAAB Alpha, Nigerian indigenous and other chicken breeds was determined using MEGA 6 software. Five polymorphisms were identified in FUNAAB Alpha chickens while twelve were identified in Nigerian indigenous chickens. All the polymorphisms identified in FUNAAB Alpha chickens were also observed in Nigerian indigenous chickens while seven polymorphisms were unique to Nigerian indigenous chickens. Higher diversity indices were observed in Nigerian indigenous chickens (number of haplotype: 4; haplotype diversity: 0.743±0.012; nucleotide diversity: 0.014±0.0013 and average number of nucleotide differences: 4.332) compared with FUNAAB Alpha chickens (number of haplotype: 2; haplotype diversity: 0.485±0.001; nucleotide diversity: 0.008±0.0001 and average number of nucleotide differences: 2.424). Positive selective forces were acting on FUNAAB Alpha chickens while negative selective forces were acting on Nigerian indigenous chickens. Phylogenetic analysis revealed that FUNAAB Alpha chickens clustered with Nigerian indigenous and South American chickens. It can be concluded that there was likely genetic erosion and loss of diversity in development of FUNAAB Alpha breed. Breeding programmes aimed at improvement of genetic diversity and reduction of genetic erosion should be applied in subsequent improvement of FUNAAB Alpha chickens.
This study was conducted to determine welfare of broiler chickens fed ad libitum and restricted feed during early (08.00hour) and late (16:00hour) of the day. One hundred and eighty (21d old) broiler chickens were randomly allocated to 4 treatments in a 2x2 factorial arrangement comprising of ad libitum and restricted feeding (75% of ad libitum) quantity at 8 and 16 hours feeding time in three replicates. Data were collected on leg problem, dust bathing, body temperature, mortality and haematology. Result revealed that neither feed quantity nor time had significant (P>0.05) effect on leg problem, dust bathing and mortality of broiler chickens. Broiler chickens under ad lib feed quantity and 16:00hours feeding time had (P<0.05) highest body temperature (40.93oC) while those under ad libitum morning (08:00hours) recorded the least (40.75°C). Pack Cell Volume had similar (P>0.05) increase from 26.75% at the beginning (21d) to 31.25 (%) at 56d with broiler chickens under restricted feeding and fed at 16:00hours feeding time. Basophil count reduced from a range of 0.5-2% (P<0.05) to 1% (P>0.05) with restricted feeding. Also eosinophil reduced from 2-4% (P<0.05) range to 0-2.5% (P>0.05) with restricted feeding while birds under ad lib increased from 0-1% (P<0.05) at 21d to 2.75% (P>0.05) at 56d. Better welfare (good body temperature) of broiler chicken could be achieved with early feeding time irrespective of quantity. However, restricted feeding could be explored in broiler production where reduced basophil, eosinophil and stress are vital for enhanced welfare and performance.
Sustainable maize (Zea mays) production in resource challenged regions of the world is achievable among others through optimal utilisation of organic fertilisers at varying rates. Field trials were conducted in Abeokuta (Latitude 7010' N and Longitude 3015' E) in the late cropping season of 2010 and 2011. Three commercially available organic fertilisers [(Gateway 1 (GF1), Gateway 2 (GF2) and Sunshine (SF)], at three rates (0, 10 and 20 t ha-1) and three replicates were used on improved open-pollinated maize variety (Swam 1 yellow). The experiment was laid out in a randomised completely blocked design. GF1 had significantly (P < 0.05) the highest effect on growth parameters (Plant height, stem girth, leaf area and leaf area Index), with SF the least. A significant depression was observed in most growth parameters at increasing application rates of organic fertiliser, a converse pattern was observed on 1000 grain weight (GW), harvest index and cob length. A significantly higher (P < 0.05) vegetative growth, cob weight and grain yield was observed in 2010 than 2011, while 2011 had longer cobs and more 1000 GW than 2010. GF1 was recommended in Rainforest transitory zone of Nigeria at higher application rates though mediated by environmental factors. Keywords: , , ,
The success of market reforms in developing countries depends to a large extent on the strength of price signals transmitted between different level of markets reflecting extent of market integration and extent to which markets function efficiently. Market integration is an indicator that efficiency exists within the flow of information between markets. This study examined price integration and transmission of food grains markets in Southwest, Nigeria. Time series data of rural and urban retail prices of local and imported rice, cowpea and maize between 2004 to 2013 were obtained from the Agricultural Development Programme (ADP) Offices in selected States. The degree of price transmission was analyzed within the framework of Vector Error Correction Model (VECM). The Augmented Dickey Fuller (ADF) unit root test results revealed that the price series were stationary at first difference. Johansen cointegration results showed that even though two Cointegrating Equations (CEs) exist between linear combinations, some stable long run equilibrium relationships exist among the price series. The study concluded that Rural Price of Local Rice in Lagos State (RPLRLS), Rural Price of Cowpea in Oyo State (RPCOYS) and Rural Price of Maize in Lagos State (RPMLS) occupied the leadership position in price formation and transmission. The study therefore, recommended that policy measures aimed at increasing consumption of local rice, cowpea and maize be implemented, in identifying the leader markets.
This study evaluated the effects of pressure cooking on the textural attributes of Bambara nuts using Response Surface Methodology (RSM).The study optimized cooking condition {Weight of Bambara (250 – 1000g), cooking time (20 -90 min) and post cooking resident time (2-12 min)} for the pressure boiling on the textural and qualities of Bambara. Five out of the eleven optimised solutions (Desirability Index range of 0.919 to 0.936) were compared with samples from conventionally boiled Bambara for proximate and sensory (colour, texture, aroma and Overall acceptance) qualities. Data were analysed using RSM, analysis of variance and PPMC. Models for hardness, springiness, cohesiveness, fracturability and sensory texture with adjusted R2 values of 83.41%, 80.99%, 67.37% , 93,75% and 88.96% respectively adequately explained the textural and sensory qualities of boiled bambara. The range of values for moisture, fat, ash, crude protein and carbohydrate were 47.88, 2.24, 1.98, 24.30, 20.91 % to 50.58, 2.58, 2.19, 25.49, 21.87% respectively. Boiled Bambara produced at verified optimisation solutions (527.62g, 82.55, 10.43 min and 591.69g, 82.96, 9.52 minutes) were not significantly different (p >0.05) from that produced by conventional method (weight and Cooking time: 500g and 125 min.) in spite of the relatively longer cooking time of the later.
Aestivation is a process of metabolic inactivity under which energy reserve are manipulated for survival. Reproductive apparatus and haemolymph biochemical agents also undergo phase manipulation as the duration continues. To determine the physiological influence on key hormone of reproduction and reproductive apparatus, seventy five A. marginata snails were used for this study. The snails were divided into five treatments with fifteen replicate each. Treatment include: Zero (0) week, Three (3) weeks, Six (6) weeks, nine (9) weeks and six (6) weeks post-aestivation. Parameters measured were: Testosterone concentration, haemolymph biochemical parameters (Total protein, albumin, globulin, Aspartate transaminase (AST) and Alanine transaminase (ALT), dimensions (length) and weight of the organs and tissues of the reproductive tracts (Ovo-testis, penis, vaginal, oviduct, little hermaphrodite duct, common hermaphrodite duct, vas deferens and albumen gland) gonado-somatic index and percentage mortality. Result showed that level of testosterone at three and six weeks of aestivation significantly reduced compared to the control. Also, at nine weeks of aestivation, the reduction was significantly greater than what was recorded at both three and six weeks of aestivation. But the testosterone levels were reversed at nine weeks post aestivation. Total protein and globulin were significantly influenced with both reaching a peak value at 9 weeks of aestivation while ALT, AST and albumin were not significantly affected. So also, of all the reproductive tract parts measured, organ weight, ovo-testis weight, penis weight and length were significantly influenced (P<0.001; P<0.001; P<0.05; P<0.001). Similarly, vaginal weight, oviduct weight, little hermaphrodite duct weight and length were also significantly affected together with vas deferens length and albumen gland length while aestivation duration had no significant influence on reproductive tract weight, ovo-testis length, vaginal length, oviduct length, little hermaphrodite duct length, vas deferens weight and albumen gland weight. Similarly, gonado-somatic index was also not significantly affected by aestivation duration. It was also obvious from this study that the highest mortality was recorded at 6 weeks of aestivation, followed by 9 weeks of aestivation while 3weeks and 6 weeks post-aestivation had the least mortality with the control intact. In conclusion, it is clear from this study that aestivation duration significantly influenced testosterone concentration, haemolymph biochemical parameters and some selected reproductive apparatus of A. marginata.
Human activities have degenerated nearly 40% of the universe soil through excessive chemical inputs, tilling and industrial activities. Biochar can increase soil fecundity, agricultural producti- vity and protects soil-borne diseases. This study aimed to assess the efficacy of rice husk biochar on the growth and yield of tomato plants. Biochar was produced through feedstock (rice-husk) pyrolysis and used as soil amendments at different concentrations (20 t/ha and 40 t/ha) and an unamend soil served as control. Physicochemical properties of the soil, rice husk, biochar and biochar soil before and after planting were determined using standard methods. Rhizospheric microflora of the plants were isolated and identified based on morphological and biochemical characterizations. Agronomic parameters such as plant height, stem girth, leaf area, number of leaves, flowers, fruits and weight of fruits were determined. Results revealed that rice husk biochar (40 t/ha) had the highest physical and chemical parameters while the unamend soil had the lowest constituents. Predominant bacterium and fungus are Bacillus subtilis and Aspergillus niger. Agronomic parameters: plant heights, stem girths, leaf areas, number of leaves, flowers, fruits and weight of fruits were higher in all the amended soil than the control at the various growth stages. The unamend soil yielded no fruit at 10th week while the amended soil yielded an average fruit weight of 34.95g ± 8.76 and 21.53g ± 5.16 at 20 t/ha and 40 t/ha respectively. This study revealed that biochar produced from rice husk could be used to improve growth and yield of tomato plants.
The knowledge of material property of the pore space through which water flow in soil for the optimization of water supplies for agricultural and engineering projects is fast becoming challenging due to intricate geometries of the media porous structures. The study determines the permeability coefficients of soils at six different Federal University of Agriculture, Abeokuta, (FUNAAB) land-use (Hostel-Site, Cashew Plantation, FADAMA Farm, COLPLANT Farm, Forest nursery unit, FUNAAB health center) in order to estimate the flow rate through the soil using an improvised constant head permeameter. The soils were initially analyzed for their physical properties before determining the flow rate and permeability coefficients. The reliability of result of permeameter was compared with standards for validity. The result shows that the soils were slightly acidic with pH average of 6.8, organic carbon ranging from 0.78% to 4.49% with the highest at the Fadama site. The total nitrogen ranged between 0.1% and 8.0% and the available phosphorus ranged between 1.20 to 3.95 mg kg-1 with the highest value experienced at cashew plantation. The improvised permeameter gave a reliable result with high positive correlation in volume rate of flow in soil and time of flow. The permeability coefficient of the soil samples (K) were in the range of 2.7 x 10-5to 4.2 x 10-5with the soil type ranging from sandy-loam to loamy sand similar to the result obtained during physical analysis. The soils were of relative permeability of semi-pervious, a characteristic of poor soil transmissivity.
This experiment was designed to determine the meat quality and lipid profile of broiler chickens fed diets containing turmeric (Curcuma longa) powder (Tur) and cayenne pepper (Capsicum frutescens) powder (Cay) as antioxidants. Two hundred and forty three (two-week old) Abor Acre broiler chicks were randomly allotted to nine treatment groups of 27 birds each, consisting of three replicates of nine birds each in a completely randomised design. Three levels of Tur (0, 2 and 4 g/kg) and three levels of Cay (0, 1 and 2 g/kg) were used to provide nine dietary treatments. Meat quality indices such as cook and refrigerated losses, water absorptive power, etc were measured and determined at the 8th week. Broiler Chickens fed the basal diet had highest meat dry matter, protein content and least (p<0.05) meat pH, cook and refrigeration loss values. Meat triglyceride and meat malondialdehyde value was best (p<0.05) in treatments fed dietary 2 g/kg Cay, while chickens fed 2 g/kg Cay, 2 g/kg Tur + 1 g/kg Cay and 2 g/kg Tur + 2 g/kg Cay had better meat lipoprotein values. For meat sensory characteristic, meat flavour of broiler chickens fed diets containing 2 and 4 g/kg dietary Tur, were moderately liked while overall flavour was best (p<0.05) in groups fed the basal diet with no dietary additive. It was evident in the study that the dietary inclusions of the test ingredients limited lipid oxidation, thus improved storage duration and meat flavor.
Seventeen West African Dwarf does housed intensively were used for this study. Does were naturally mated and pregnancy was confirmed by non-return to oestrus. The predicted parturition date was calculated. Two days to the predicted date of parturition, the does were closely monitored until the day they actually kidded. The behaviours of the does (duration of parturition, and latency to groom kids) and the kids (latency to stand) were recorded. Data were subjected to independent T-test of SPSS statistical package. The mean duration of parturition in WAD does was 9.5±2.65 min and the latency of kids to stand was 10.5±3.45mins. Duration of parturition was greater (P<0.05) in the 1st than 2nd parity does. A significant negative correlation was established between parity and duration of parturition (r =-0.635, P˂0.05). Kids from 1st parity does stood up earlier (P<0.05) compared to those from the 2nd parity does. A positive correlation was established between parity and the latency of the kids to stand (r = 0.598, P˂0.05). In conclusion, the duration of parturition and latency of kid to stand were not affected by the sex of the kid delivered, however WAD does groomed female kids earlier than the male kids.
This study assessed the levels of air pollutants emitted outdoor of farm settlements (FS), the seasonal and temporal variations, and the relationship among the parameters monitored. Seven FS within Ogun State were investigated, with 211 sampling points established across the FS. The concentrations of VOCs, SO2, NO2, CO, O3, NH3, CO2, TSP, PM2.5 and PM10 were monitored in replicates using active potable samplers while bacteria and fungi were isolated using settle plate technique. Descriptive (means and standard deviation) and inferential statistical tools (Pearson correlation) were used to analyse the data. The mean ranges of VOCs, CO and CO2 (ppm); 20.8±10.53 – 48.67±19.05, 17.95±6.65 – 21.5±3.93, 3562.15±1200.85 – 4266±1176.85, and for bacteria and fungi (cfu/m3); 548.98±1.18 – 2255.01±1.27 and 525.68±1.15 – 1282.38±1.27 respectively were above the threshold limits. There were significant seasonal, spatial and temporal differences among observed means of VOCs, CO2 O3, TSP, PM2.5, and fungi. The bacteria and fungi count increased as TSP, PM2.5 and PM10 increased. The study established that levels of air pollutants are dependent on the type of farming practice.
The experiment was conducted to investigate meat quality of improved indigenous chickens (FUNAAB alpha) fed diet containing turmeric (Curcuma longa) and clove (Syzigium aromaticum) powders. One hundred and thirty-five (135) mixed sexed day-old improved indigenous FUNAAB alpha chicks were brooded collectively for two weeks, and assigned into three (3) treatment groups. Each treatment was replicated three times, consisting of fifteen (15) birds. Feed and water were provided ad-libitum through the duration of experiment. The control group was fed the basal diet at starter and finisher phases (T1), while the other groups were fed clove (Syzygium aromaticum) powder at 3 g/kg (T2) and turmeric (Curcuma longa) (T3) powder at 4 g/kg respectively as additives. Data obtained were subjected to a One – Way Analysis of Variance in a Completely Randomised Design. Muscle obtained after evisceration was subjected to quality analysis. Proximate composition of meat obtained from chickens fed the basal diet had the highest (p<0.05) moisture content value of 75.45% compared to other treatments. Water absorptive capacity and cook loss of meat obtained from chickens fed 4 g/kg dietary turmeric showed (p<0.05) values of 3% and 16.4% respectively. Meat sensory properties analysed revealed (p<0.05) score in groups fed 3g/kg and 4 g/kg clove and turmeric powders respectively, for tenderness (6.14) and overall acceptability (7.19). Meanwhile (p<0.05) lipoprotein profile was observed in group fed 4 g/kg turmeric powder. Inclusion, turmeric and clove had beneficial effects on FUNAAB Alpha.
African pear fruit (Dacryodes edulis) is a highly sought for multipurpose agroforestry tree species that has the potential for both local and international trades, Nigeria is among the leading producer of the fruit, but its pattern and extent of its genetic variability is currently unknown. Hence, a study was carried out to determine the pattern and extent of genetic variability and interrelationships among 13 morphological traits of African pear fruit accessions. The experiment was laid in a Completely Randomized Design in 5 replications. Data collected on number of leaf production, leaf length, leaf breadth, leaf length/breadth ratio, internode distances, plant height, collar diameter, fresh leaf weight, fresh stem weight, fresh root weight, dry leaf weight, dry stem weight, dry root weight and biomass accumulation were subjected to Analysis of Variance. Treatment means were separated using Duncan’s Multiple Range Test at 5% probability level. Results showed significant (p<0.05) differences among the D. edulis genotypes for most of the traits evaluated indicated variation in the performance of the genotypes and pattern of clustering indicated that there was no association between eco-geographical distribution of genotypes and genetic diversity. PCA revealed that fourteen axes accounted for 100% of the variations observed while the first five axes contributed 73.23% of the total variation observed. The first axis accounted for 25.61% of the total variation while the second and third accounted for 15.43 and 15.01%, respectively. The fourth axis contributed 9.82% of the total variation while the fifth axis contributed 7.36% of the total variation. Significant phenotypic and genotypic correlations were observed between most of the plant characters evaluated and biomass accumulation which is an indication that the phenotypic association will be a good index for the genotypic association.
