Manuscript Preparation and Formatting of Regular articles
All portions of the manuscript must be typed double-spaced and all pages numbered starting from the title page.
Title: The title should be a brief, concise and informative phrase describing the content of the paper. Each title should be unique and not more than 30 words. It should be followed by a list of the authors, with first names as initials only (preceding the name) and with each name separated by a comma, except for the last two which are separated by 'and'. The list of names should be followed by a list of authors' addresses. The address (including e-mail, phone and fax) and author for correspondence should be indicated by superscript letters and symbols where there is more than one author and address. A short title of not more than 60 characters (including spaces) should be provided at the top of the title page, in italics, with Latin names not in italics.
Abstract: This should indicate concisely, not exceeding 250 words in one paragraph stating why and how the work was done, scope, major findings and conclusions. Abstracts should not be unnecessarily descriptive and must, where appropriate, contain quantitative data. The Abstract should. Complete sentences, active verbs, and the third person should be used, and the abstract should be written in the past tense. Standard nomenclature should be used and abbreviations as well as literature should be avoided.
Following the abstract, about 3 to 5 key words that will provide indexing references should be listed alphabetically.
Introduction: The introduction section should provide a clear statement of the problem, the relevant literature on the subject, and the proposed approach or solution in a logical manner. It should be understandable to readers from a broad range of scientific disciplines.
Materials and methods: This section should be as detailed as possible to allow experiments to be reproduced. Sufficient information must be given in this section to allow the reader to understand the experimental design and statistical methods used in the data analysis. Details of specific statistical package used for the analysis should be given. However, only truly new procedures should be described in detail; previously published procedures should be cited, and important modifications of published procedures should be mentioned briefly. Capitalize trade names and include the manufacturer's name and address. Subheadings should be used. Methods in general use need not be described in detail.
Results: Results of the experiment should be concise and clearly expressed. The results should be written in the past tense when describing findings in the authors' experiments. Results should be explained, but largely without referring to the literature. Discussion, speculation and detailed interpretation of data should not be included in the Results but should be put into the Discussion section.
Discussion: The discussion section should interpret the findings in view of the results obtained in this and in past studies on this topic. State the conclusions in a few sentences at the end of the paper. The Results and Discussion sections can include subheadings, but both sections should be separated.
Acknowledgments: Acknowledgments of people, grants, funds, organization, etc should be very brief.
Tables should be kept to a minimum and be designed to be as simple as possible. Tables are to be typed double-spaced throughout, including headings and footnotes. Each table should be on a separate page, numbered consecutively in Arabic numerals and supplied with a heading and a legend. Tables should be self-explanatory without reference to the text. The same data should not be presented in both table and graph form or repeated in the text. Tables should be prepared in Microsoft Word.
Figure legends should be typed in numerical order on a separate sheet. Graphics should be prepared using applications capable of generating high resolution GIF, TIFF, JPEG or Powerpoint before pasting in the Microsoft Word manuscript file. Use Arabic numerals to designate figures and upper case letters for their parts (Fig 1). The figure should be self explanatory.
References: In the text, a reference identified by means of an author‘s name should be followed by the date of the reference in parentheses. When there are more than two authors, only the first author‘s name should be mentioned, followed by ‘et al.’. In the event that an author cited has had two or more works published during the same year, the reference, both in the text and in the reference list, should be identified by a lower case letter like ’a‘ and ’b‘ after the date to distinguish the works.
References should be listed at the end of the paper in alphabetical order. Articles in preparation or articles submitted for publication, unpublished observations, personal communications, etc. should not be included in the reference list but should only be mentioned in the article text (e.g., A. O. Oni,UniversityofAgriculture,Abeokuta, personal communication). Authors are fully responsible for the accuracy of the references.
All journal titles in the Reference List should be written out in full and in italics. Examples are given below.

Units and Quantities
SI units are preferred. Others should be related to SI units at the first mention. Numbers preceding units should be written as numerals; those preceding other items up to nine should be spelt out; e.g. 8 cm, 2 days, nine fields, 10 leaves. Units should preferably be explicit, e.g. 1 g/L or 1 g L-1 rather than 0.1% w/v. Whereas grams per litre can be indicated as g L-1, spores per litre is written as spores per L.
Latin binomials
Except in taxonomy papers, Latin binomial names are given without authorities.
Offprints
Electronic offprint of the published article will be provided free of charge to the corresponding author upon request. Paper offprints of the printed published article may be purchased if ordered via the method stipulated on the instructions and must accompany the proofs. Printed offprints are posted to the correspondence address given for the paper unless a different address is specified when ordered. Note that it is not uncommon for the printed offprints to take up to 8 weeks to arrive after publication of the journal.
