Abstract
The primary purpose of this study was to assess the information needs of cocoa farmers in Edo and Ondo states. Specifically, the study was conducted to investgate the information needs assessment of cocoa farmers; ascertain the farmers’ preference for cocoa information sources; examine cocoa farmers information needs and farmers search behavior and examine cocoa
farmers’ constraints to information accessibility in the study area. Multistage random sampling procedure was used to select 432 respondents while a structured interview schedule was used to solicit information from the respondents.
The data were analyzed using descriptive statistics and inferential statistics (Binary logit regression, Pearson’s Product Moment Correlation (PPMC) and 2x2 matrix used to establish the priorities mean score). The result revealed that the mean age of cocoa farmers was 52 years while majorities (70.4%) of the farmers were male. Majorities (35.4%) of the farmers had formal
education, higher membership of a group (93.5%) and were married (80.3%). Majority (74.3%) of the cocoa farmers’ cultivated farm lands of less than 10 hectares with a mean farming experience of 22 years. This study revealed that the most prominent sources of information wasinput dealers/suppliers (( =2.86±0.40), while Television (
=2.80±0.50) and face to face advice by other farmers ( =2.76±0.56), extension posters=2.87±0.45) were the most preferred among the institutional bodies, mass media electronics, print media and traditional sources of information respectively. The mean score for weed control (control ( =3.14) and pest and disease =3.14) which were ranked 2nd in cocoa production information needs were ranked 1st and 4th in level of information search with the mean values of ( =2.24) and ( =2.03)respectively. Hence, the farmers need training in their information search behaviour.
From the Matrix presentation, it was observed that cocoa production information with the discrepancies scores of farm layout with a weighted mean score of 5.48, farm cultivation system with a weighted mean score of 4.82 and seed selection and planting materials which had a weighted mean score of 4.67 were the critical areas where cocoa farmers need training or
education in cocoa production information needs. Binary Logistic Regression indicated that the Nagelkerke R square value of 0.15 and 0.29 for Edo and Ondo States respectively indicated that the determinants would collectively explain about 15.0% and 29.5% variation in cocoa production information needs of farmers, respectively in the study area. Also the
binary logistic regression test indicated that extension agents (t= 1.61; p≤0.01); input dealers/suppliers (t=2.89;p≤0.01); internet (t=- 1.65 p≤0.01), cable network (t= 2.56; p≤ 0.01); family members (t= 0.92;
p≤0.05) and face to face contact with other farmers (t =0.67; p≤0.01) were the most significant preferred sources of information on farmers production infomtion needs. The finding ofPearson’s Product Moment Correlation indicated that positive and significant correlation exists between production information needs (r=0.271; p≤0.01) and postharvest information needs
(r=0.303; p≤0.01) and farmers’ search behaviour for information

Abstract
This research gives attention to the non-energy use of Lignite samples collected from Ohordua town of Edo State and Azagba-Ogwashi in Delta State. A total of six composite Lignite samples,from ten sampled points were subjected to analytical study, with a view to determining their humic content and properties for use in soil beneficiation and conditioning.Proximate and Ultimate analytical technique was used to characterize the lignite from which humic acid was extracted under alkaline condition, and precipitated using acidic medium of 6M HCl.X-Ray Diffraction and X-Ray Fluorescence analytical methods were employed to determine the mineralogical and elemental composition of the samples respectively,while Ultra-Violent visible spectroscopy was used for organic characterization of the humic acid.Proximate analyses of the Lignite show percentage composition of Ohordua and Azagba-Ogwashi Lignite respectively,Fixed Carbon (65.22 wt% and 67.16wt%),Moisture Content (26 wt% and 25.4wt%) and Ash (5.02 wt% and 4.5 wt%).Ultimate analyses shows Hydrogen (6.60 wt% and 6.22wt%), Nitrogen (1.34 wt% and 1.19wt%,) Sulphur (0.77 wt% and 0.70wt%), Oxygen (26.07 wt% and 24.73 wt%), for Ohordua and Azagba-Ogwashi respectively.The analytical results suggest the existing lignite with varying thickness is of Lignite rank. The Ultimate analyses of the extracted Humic acid show Carbon (57.5wt% and 55.8wt%)%, Hydrogen (5.1 wt% and 3.9wt%), Nitrogen (2.5 wt% and 1.1wt%), Sulphur (Nil and 0.3wt%) and Oxygen (34.9 wt% and 38.9wt%,) for Ohordua and Azagba-Ogwashi, respectively.The mineralogical composition in the lignite samples shows Kaolinite was the main clay mineral identified. Non clay minerals such as anorthite, drierite, yeelimite, spurite, belite, wollastonite, hematite, pyrite, bauxite and quartz were detected.For Ultra-Violent visible spectroscopy characterization of the Humic Acid, E2/E3 and E4/E6 absorption values for Ohordua (21.69 and 4.50) respectively, while Azagba-Ogwashi reveal (19.39 and 4.6) respectively. The humic substance has percentage aromaticity values of 33.90% and 34.06%, total acidity has 10.4% and 10.1%, COOH has 3.4% and 3.3%, Phenolic has 7.0% and 6.8% and acidity ratio has 0.49% and 0.48%, for Ohordua and Azagba-Ogwashi, respectively which depicts the Humic Acid has a high degree of Humification and a very good total acidity ratio. Results from this research indicate that the Lignite from both locations are similar in geochemistry, mineralogy and organic properties. Although,humification is high in both samples, Ohordua Lignite with lesser aromaticity and E4/E6 ratio, higher E2/E3 ratio and higher acidity ratio is more suitable for soil beneficiation and conditioning than that of Azagba-Ogwashi.

Abstract
ABSTRACT
Numerical schemes for the integration of stiff initial value problems are required to
possess wide region of absolute stability which include the entire left of the complex
plane. Numerical schemes that are explicit usually do not attain the requirement for
integration of stiff initial value problems. In this study, implicit second derivative RungeKutta methods are constructed for the integration of stiff initial value problems.
A family of generalised second derivative mono-implicit Runge-Kutta (GSDMIRK)
method is derived using the method of Tailor series expansion.
The proposed GSDMIRK methods are 𝐴-stable for stage 𝑠=3 𝑎𝑛𝑑 4 and 𝐴(∝)-stable for
𝑠=5 𝑎𝑛𝑑 6. Numerical experiments show that the GSDMIRK methods perform better
when compared to some numerical algorithms in the literature.

Publication Type
Abstract
Over the years, human trafficking which involves the trafficking of people especially young and
able bodied people for forced labour and prostitution has become a recurrent problem in Nigeria
human trafficking has been an endemic social problem in Edo State in which the state alone
constitute about 46 percentage of human trafficking in Nigeria. It was in an attempt to tackle to
tackle the menace of human trafficking in Nigeria that the Federal government established
National Agency for the Prohibition of traffic in persons and other related matters (NAPTIP) in
2003. The agency is saddled with the onerous responsibility of investigating and persecuting
offenders of this heinous crime. On this note, this study has assessed the role of the agency in
combating human trafficking in Nigeria with special focus on Edo State which is notorious and
endemic hub for human trafficking in Nigeria. This study has identified the root causes of human
trafficking tits social and economic consequence in Edo State. It has also examined the strategies
adopted by National Agency for the Prohibition of traffic in persons and other related matters in
combating the menace as well as the challenges the agency has faced in carrying out its statutory
responsibilities. This has established that successes recorded so far by (NAPTIP) have been the
collaborative efforts of other stakeholders such as the European Union, (EU) International
Organization for Migration (IOM), Non-government organizations, civil society groups, local
non-government organizations as well as the traditional institution of Benin, the Oba and his
chiefs in the fight against the scourge. Despite several efforts by the government in collaboration
with local and international non-governmental organizations, humanitarian and civil society
organizations, human trafficking is still to be totally eradicated.

Abstract
Hydropriming has proved to be the most potent form of seed germination enhancement in not just final germination but also in speed of germination and time taken to reach 50% of total germinated seeds of Napoloenaea vogelii Hook. and Planch. Priming seeds in solutions significantly affected seed germination (P<0.05), with smoke water treatments, hydro and halopriming having significantly higher germination means Maximum germination percentage was observed in hydropriming with 90% germination while Halopriming (NaCl 2, and 4g/l) had total germination percentages of 85% each. Napoleonaea vogelii seeds also responded positively to smoke water treatment for 10 and 20 minutes with 80% and 77.50% respectively. Effect of bush fire proved to be deleterious, showing the lowest germination percentage of 32.50%. Seeds collected from decaying fruits on trees has low mean germination percentage of 34.17%. The effect of various treatments was significant on the speed of germination. All forms of priming showed improved speed of germination with hydropriming being superior with a mean speed of 2.99 day-1. Control showed the least speed with 0.39 day-1. Plants in complete darkness showed the highest mean growth in height (32.42cm) while those in 24hrs light showed lowest growth in height (18.88cm). Hydropriming and Halopriming (2g/l) also showed significant growth in heights (24.12cm and 24.08cm respectively). The seeds of Diospyros barteri Hiern. did not show any germination under all treatments given to seeds.
