Determinants of Entrepreneurial Skill Acquisition among Agricultural Students in Nigeria Universities in Ogun State

Entrepreneurial skill acquisition among agricultural students in Nigeria Universities has been of major concern due to explosion rate of unemployment in the country. In the study that investigated the determinants of the entrepreneurial skills acquisition among agricultural students in universities located in Ogun State, 40 students were purposefully selected University of Agriculture, Tai Solarin University of Education and Olabisi Onabanjo University making a total of 120 students as the study sample. The findings revealed that majority of the students were in the age grade of 21 – 24 years (63.1%), male (71.7%), Christian (52.5%) and from Department of Agricultural Economics, Agricultural Extension and Rural Sociology, Home and Hotel Management Department, Department of Animal Production, Department of Crop production Department of Soil Science and Farm Mechanization and Department of Renewable Resources. Majority of the respondents posited that they had acquired fish, pig, crop, poultry rabbit, cattle, snail and grass-cutter productions. Also, the students posited that they have leadership skill, self confidence, ability to organize resources to achieve goals, innovate and speculate, have need for achievement and success in skill acquired and lastly possess strong desire for responsibility and independence respectively. Also 70.8% of the respondents agreed that the level of the skill acquired determined their efficiency as entrepreneur. The study  therefore recommended that economic policy and programs that are geared towards self reliance for individuals such as Open Apprenticeship Scheme, Graduate Employment Programs etc and other policies that encourage or make it easy for entrepreneurs to acquire the needed funds e.g.; Peoples Bank of Nigeria, Funds for Small-Scale Industries (FUSSI), co-operative societies etc must be established throughout the nation and also empowered by the Government to assist entrepreneurs in Nigeria especially graduates from Universities.

Genetic variation and relationship in Staphylococcus aureus isolates from human and food samples using random amplified polymorphic DNAs

A genetic characterization of 18 different isolates of Staphylococcus aureus using random amplified polymorphic DNAs (RAPDs) was carried out. Out of one hundred primers tested, ten showed polymorphism. The amplification reactions with the 10 primers generated 88 bands, 51 of which is polymorphic with band size ranging between 200 and 3,000 bp. Variation and relatedness between different isolates were determined by converting RAPD data into a Jaccard similarity matrix and analysed by UPGMA (unweighted pair-group method, arithmetic average) to produce completely twelve different groups at 100% Jaccard similarity and at 50% coefficient of similarity. The isolates were classified into two major groups, the first comprises of mildly and weakly virulence, while the other group are the highly virulence Staphylococci. The results demonstrated that the RAPD technique may be of great use in the classification of Staphylococcus aureus.African Journal of Biotechnology Vol. 4 (7), pp. 611-614, 200

Genetic Analysis and Molecular Identification of Virulence in Xanthomonas oryzaepv.oryzaeIsolates

Bacterial leaf blight (BLB) of rice is a very destructive disease worldwide and is caused byXanthomonas oryzaepv.oryzae(Xoo).The aimofthepresentstudywastoexamineiftheXoovirulence pathotypes obtained using phenotypic pathotyping could be confirmed using molecular approach. After screening of 60 Operon primers with genomic DNA of twoXooisolates (virulent pathotype,Vr, and mildly virulent pathotype,MVr), 12 Operon primers that gave reproducible and useful genetic information were selected and used to analyze 50Xooisolates from 7 West African countries. Genetic analysis revealed two majorXoovirulence genotypes (Mta andMtb)withMtahaving two subgroups (Mta1andMta2).Mta1(Vr1) subgroup genotype has occurrence in six countries and Mta2(Vr2) in three countries whileMtbgenotype characterized mildly virulence (MVr)Xooisolates present in five countries. The study revealed possible linkage and correlation between phenotypic pathotyping and molecular typing ofXoovirulence.Xoo virulence genotypes were known to exist within country and there was evidence ofXoopathogen migration between countries. Durable resistance rice cultivars would need to overcome bothMtaandMtb Xoovirulence genotypes in order to survive after their deployment into different rice ecologies in West Africa

Alkylating efficiency of sodium azide on pod yield, nut size and nutrition composition of Samnut 10 and Samnut 20 varieties of groundnut (Arachis hypogea L.)

Mutation has been utilised to improve growth and yield of many food crops, but only little effort has been made to ascertain the nutritional advantages in such improved crops. The present study evaluates the alkylating efficiency of sodium azide of different concentrations on pod yield, nut size and nutritional composition of two groundnut varieties. Dry seeds of groundnut (Arachis hypogea L.); Samnut 10 and Samnut 20 varieties obtained from the Ministry of Agriculture, Ilorin, Kwara State of Nigeria were treated with different sodium azide concentrations (10, 20, 30, 40 and 50mM) for 12 hours. Seeds soaked in distilled water for 12 hours were used as control for each variety. The treated seeds and control were sown in planting bags in randomized complete block design with three replicates. Alkylating effects of the treatments were studied on pod parameters and nut size while proximate analysis was carried out on the nuts to determine their nutritional composition. The results showed that sodium azide treatment of 50 mM produced significantly taller plants with more branches and leaves. Analysis of collected data revealed that sodium azide is effective in achieving significantly earlier- maturing plants with higher pod yield, bigger nut size and heavier nuts. All concentrations of Sodium azide applied induced significant higher crude protein and fat with respect to control in samnut 10 while 50 mM yielded highest protein and fat in samnut 20 variety. Generally, nutritional values of the studied groundnut were improved by sodium azide treatments with respect to protein and fat content which are the most important constituents in groundnut utilization as food or raw material for edible oil. The study concluded that the alkylating effect of sodium azide was effective on pod yield, nut size and other nut characteristics of groundnut and could be employed to improve protein, crude fat and other nutrition contents of the nuts for human and animal consumption as well as industrial applications.Key words: Alkylating effect, nutrition composition, sodium-azid

Two genotypes of Xanthomonas oryzae pv. oryzae virulence identified in West Africa

Bacterial leaf blight (BLB) caused by Xanthomonas oryzae pv. oryzae (Xoo), is a very destructive rice disease worldwide. The aim of the present study was to examine if the Xoo virulence pathotypes obtained using phenotypic pathotyping could be confirmed using molecular approach. After screening of 60 Operon primers with genomic DNA of two Xoo isolates (virulent pathotype, Vr and mildly virulent pathotype, MVr), 12 Operon primers that gave reproducible and useful genetic information were selected and used to analyze 50 Xoo isolates from 7 West African countries. Genetic analysis revealed two major Xoo virulence molecular type (Mt) which were Mta and Mtb with Mta having two subgroups (Mta1 and Mta2). Mta1 (Vr1) subgroup genotype has occurrence in six countries and Mta2 (Vr2) in three countries while Mtb genotype characterized mildly virulence (MVr) Xoo isolates present in five countries. The study revealed possible linkage and correlation between phenotypic pathotyping and molecular typing of Xoo virulence. Durable resistance rice cultivars would need to overcome both Mta and Mtb Xoo virulence genotypes in order to survive after their deployment into different rice ecologies in West Africa

Bayesian Spatial Analysis of Socio-Demographic Factors Influencing Smoking, Use of Hard Drugs and Its Residual Geographic Variation among Teenagers of Reproductive Age in Nigeria

The use of hard drugs (Alcohol, cocaine and Nicotine) has remained the censorious issue globally and in Nigeria. The use of hard drugs and tobacco smoking is common in the stage of adolescence and youth life, which is a deterrent to education and career advancement. Hence, this study looks into socio-demographic factors that influence the use of hard drugs and tobacco smoking among teenagers between the ages of 15 years to 19 years. To achieve this objective, a cross-sectional data was used and a secondary data was obtained from DHS - National Demographic and Health Surveys (NDHS) from the survey year 2018. Some Bayesian models were developed and Conditional Autoregressive (CAR) model with random walk 1 (RW1) was the best model. The study unveiled a positive significant association of settlement, previous place of residence, education attainment, religion, ethnicity, literacy with reported use of hard drugs amongst teenagers of reproductive age

Genetic Analysis of Effect of Heat Stress on Genomic DNA from Cowpea ( Vigna unguiculata (L) Walp.)

Aims: Genetic analysis was used to study the effect of heat st ress on young seedlings of cowpea ( Vigna unguiculata (L) Walp.). Study Design: Four different colors of cowpea seeds (white, dirty w hite, deep brown and light brown) were obtained from GeneBank of International Institute of Tropical Agriculture (IITA) Ibadan, Nigeria. Seeds from each of the cowpea four colors we re first pre-germinated and young seedlings subjected to DNA extraction. Extracted DNA subjected to different temperature treatments at 75°C and 100°C for one hour and control not heated. Place and Duration of Study: Department of Chemical Sciences Afe Babalola University Ado Ekiti, Nigeria between January 2015 and June 2015. Methodology: UV wavelength absorption spectrum analysis (A 200 – A 960 ) was carried out on control DNA and DNA heated at 75°C and 100°C respectively. Cl uster analysis of optical density (OD) data was carried out to establish the relationship between co ntrol DNA and heat treated DNA (75°C and 100°C). Results: DNA concentrations of Vigna unguiculata (L) Walp. were between 0.40 to 1.15 mg/ml, 0.33 to 0.84 mg/ml, and 0.26 to 0.89 mg/ml for control a nd heat treatments of 75°C and 100°C respectively. DNA UV absorption spectra of control and heat treatments of 75°C and 100°C were generally different due to differential UV wavelengt h absorption. Cluster analysis revealed three different clusters (cluster 1, cluster 2 and cluster 3) among control DNA and heat treated DNA. Cluster 1 comprised of V1-control, V1-75°C and V1-10 0°C, with V1-75°C and V1-100°C having similar characters. Cluster 2 was made up of V4-control, V4-75°C and V4-100°C, with V4-75°C and V4-100°C having the same characters. Cluster 3 was largel y characterized by dissimilar DNA extracts of V3-75°C, V2-control, V3-100°C, V2-100°C, V 3-control and V2-75°C. Conclusion: Genetic diversity among individual Vigna unguiculata (L) Walp. accession DNA as obtained in this study could possibly be as a result of variations in heat tolerance among dissimilar cowpea genomic composition
