AUTHOR/REVIEWER GUIDE
Scope of Articles
African Journal of Horticultural Science (AJHS) publishes research, review or short communication articles in a wide range of applied and basic horticultural areas dealing with biotechnology, economics, marketing, education, extension, engineering, environment, policy, science, sociology, technology and training. Special emphasis is given to development, research and technology transfer, both in physical and natural sciences, particularly as they relate to major areas of concern in horticulture. Articles being considered for publication elsewhere or published previously will not be considered. All materials submitted for publication will be reviewed and edited to meet standards of the African Journal of Horticultural Science.
Language of Publication
The journal publishes papers in English language only. Use of complex jargon must be avoided.
Format of Manuscripts
Manuscripts should be typewritten on one side of plain white A-4 paper, double-spaced, with 2.5 cm margins and free of errors, with left and right justified, one space between paragraphs, but no tab at the beginning of each paragraph. The font type should be Times New Roman throughout the manuscript and font size should be 12 for the main body text. Font size may be slightly reduced in the Abstract, Figures, Illustrations and Tables. Complex equations must be hand-written for clarity in typesetting.
Parts of a Research Manuscript
Research manuscripts should preferably range from 3,000 to 4,000 words. Pages should be centrally numbered at the bottom. Each manuscript should contain the following:
- Title page
- Abstract
- Introduction
- Materials and Methods
- Results and Discussion
- Conclusions and Recommendations
- References
- Tables, Figures/Illustrations
Title
Should be succinct, descriptive of the research reported and not exceed fifteen (15) words. It should be followed by a by-line with authors’ names, physical and e-mail addresses. The corresponding author should be indicated below the contacts.
Abstract
Each research article must have an abstract that is a non-critical informative digest of the contents, conclusions and recommendations of the article. Each manuscript should have an abstract written in a single paragraph of 300 words maximum, including key words. Below the abstract, indicate authors’ key words of up to eight for indexing purposes.
Introduction
The article should begin with an Introduction, defining the problem, stating the hypothesis(es), objectives, and a brief survey of the relevant literature. It should immediately follow the abstract after skipping only one space.
Materials and Methods
Should clearly and correctly describe the materials used, their sources, conditions, experimental design, steps and data analysis procedures to enable others adopt or double-check findings.
Results and Discussion
Results support or reject the hypotheses or answer the questions stated in the introduction. The discussion section interprets the data and draws conclusions and recommendations.
Tables
Tables must be cited in the text in numerical order and present material that is not included in the text or figures. Tables should appear as part of the text near where they are first cited. Tables should be numbered in Arabic numerals (e.g. Table 1) and given specific titles at the top. Values in tables should not be enclosed in grid lines, but be given the top, bottom and subheading borders only.
Figures
Figures must be cited in the text in numerical order and present material that is not included in the text or tables. Figures should appear as part of the text near where they are first cited. Figures should be numbered in Arabic numerals (e.g. Figure 1) and carry specific titles at the bottom. An appropriate scale bar on the figure should be used to indicate magnification. Lettering on the figures must be sharp, large and dark enough to withstand reduction Legends to figures should be included in the figure, giving sufficient data to make the figure comprehensible without reference to the text. Captions can be included after the title.
Illustrations
Illustrations should be in black and white. If colour is necessary, the cost of re-production will be charged to the author(s). Pictures submitted to grace the journal cover must be in colour, a soft copy and a sharp print.
Units
Units of measure should be metric standard international and clearly indicated.
Abbreviations
Only standard abbreviations should be used; unusual ones should be given initially in full with the abbreviation in parentheses, thereafter abbreviated.
References
· Only articles or books that have been published or are accepted for publication may be listed in references. Papers presented at conferences or symposia may be listed only if proceedings are published.
· References must be cited in the text by author and date; e.g. (Macharia, 1983), (Kinuthia and Mbugua, 2000), or (Olembo et al., 2005) [in case of more than two authors], (Macharia, 1983; Kinuthia and Mbugua, 2000; Olembo et al., 2005) [in case many citations follow a fact]. Move parenthesis to enclose the year only if the citation is opening a sentence or is following the word by… .
