Preparations of the manuscript for publication

Paper. Its length should not exceed the minimum length required for precision in describing the experiments and clarity in interpreting them. Manuscripts should be written in English. Paginate the entire manuscript in the top right-hand section of the pages.

Format of the paper. Contributions should be organized in the sequence: title, authors, abstract, key words, list of abbreviations, Introduction, Materials and Methods, Resultsand Discussion, Conclusions, Acknowledgements (if there are any), References. The font should be ‘standard’, preferably 12-point Times New Roman.

Title. Title of the paper should be brief, accurately identifying the manuscript content, being written in bold letters, without any abbreviations.

Authors. The forename and surname of each author are to be stated below the title. The institutional affiliations of authors are to be written below the names. If the coauthors are not all at the same institution or department, numbers in suffix should be used to refer the affiliations (1, 2). The name and e-mail of corresponding author should be mentioned, marked with asterisk (*).

Abstract and keywords. Abstract should briefly and specifically state the purpose of the research, the principal results, summarize the conclusions. A well written abstract can attract the attention of potential readers and increase the likelihood that the published paper will get cited by other researchers. The keywords must be properly selected to present the essence of the study.

Illustrations. They should be sent as jpg (with quality no less than 9), png, tif, xls, eps files for figures, graphs, diagrams, photos, etc. and as doc and docx files for tables. Graphical materials should be preferred. Tables, figures, graphs and other illustrations should be numbered consecutively with Arabic numerals and with adequate title and legend. Tables and other illustrations should be submitted on separate sheets, and must be cited in the text. The position of each table, graph, figure, etc. in the text must be indicated as a comment. Photographs/pictures should be made with high contrast. Each illustration should be accompanied by a caption. Put the captions on a separate list at the end of the manuscript. Explanations should be typewritten under the illustration and given in this list, too.

+Figures. Graphs/diagrams should be prepared preferably in Excel. Provide figures with good contrast; drawings with dark, heavy lines, letters – large enough, as to be appropriate for printing.

+Tables. They should be as simple and as few as feasible for the presentation of the essential data, prepared in MS Office Word. They should be furnished with titles of phrase or sentence. Tables should be numbered consecutively with Arabic numbers, each column in the table with heading. Authors should take notice of page size A4. The tables should preferably be located along the page, without turning it horizontally. Large tables should be avoided. If many data are to be presented, an attempt should be made to divide these over two or more tables. Explanations essential to the understanding of the table should be given at the bottom of the table marked in appropriate way.


  1. All references to publications made in the text should be presented in a list with their full bibliographical description.
  2. In the text - refer to the author's name (without initial) and year of publication. Example: Kirda (2004) also reported… Three species of aphids have been reported on triticale (Krasteva., 2013).
  3. If reference is made in the text to publications written by more than two authors the name of the first author should be used, followed by "et al.". Example:

Therefore the necessity arises to… enhancing its tolerance to stress (Boyadjieva et al., 2009; Mohammadi et al., 2010; Arani et al., 2011; Bennett et al., 2012).

The "et al." indication, however, should not be used in the list of references. In this list names of authors and co-authors, should be mentioned instead.

  1. References in the text should be arranged chronologically (see the example in item 3). The list of references should be arranged alphabetically on author's names, and chronologically per author. The following order should be used: a) publications of the single author, arranged according to publication dates – b) publications of the same author with one co-author – c) publications of the author with more than one co-author. Publications by the same author(s) in the same year should be listed as 1992a, l992b, etc.
  2. Names of authors and title of journals, published in non-latin alphabets should be transliterated in English.
  3. Use the following system of transliteration of Cyrilic: А = A, Б = В, В = V, Г = G, Д = D, Е = Е, Ж = Zh, 3 = Z, И = I, Й = Y, K = К, Л = L, М = М, Н = N, О = О, П = Р, Р = R, С = S, Т = Т, У = U, Ф = F, X = H, Ц = Тs, Ч = Сh, Ш = Sh, Щ = Sht, Ъ = А, Ь = Y, Ю = Yu, Я = Ya.
  4. A notation such as "Bg" for Bulgarian, "Ru" for Russian, "Sb" for Serbian (in case of titles in Cyrillic), "Mo" for Mongolian, "Gr" for Greek, "Geor" for Georgian, "Ja" for Japanese, "Ch" for Chinese etc. should be added after the bibliographical entry in brackets, showing the original language, when the original alphabet is other than Latin.
  5. Use the following system for arranging your references:
