Guide for Authors


The journal publishes original articles, reviews and short communications that contain original experimental data or new interpretations of existing results. They must comply with the themes of the journal and have not been published elsewhere. Plagiarism is unacceptable for the journal. Use of foreign ideas and images in their original form is allowed only in their exact citation. All submitted articles are checked for plagiarism and when there are large parts already published texts or data, the articles are rejected. We do not accept manuscripts that are fully or partially published in other publications. The manuscript, written in Bulgarian or English, should be submitted online.

Structuring of publication

Original articles should contain title, authors, abstract, key words, introduction, materials and methods, results and discussion, conclusions, references.

Text should be in Times New Roman font, in MS Office Word format. The measuring units (cm, m, km, t, l, g, kg, s, h, etc.) should be denoted according to the SI system. Latin names of plant and animal species should be given according to the International Classification, in Italic.

The text should be organized as follows:

TITLE: Title of the paper should be brief, accurately identifying the manuscript content, without any abbreviations. The forename and surname of each author are to be stated below. Institutions for which authors work are to be written below, numbers in suffix should be used to refer the affiliations of authors (1, 2). The name and e-mail of corresponding author should be mentioned, marked with asterisk (*).

ABSTRACT AND KEYWORDSAbstract reflects shortly and clearly the basic information and scientific impact of the article, with cited the main results obtained. Keywords must be properly selected, giving the essence of the study. No more than 6 key words have to be stated. Bulgarian contributors must send abstract and keywords in Bulgarian and English.

INRODUCTION: Introduction must answer the following questions: What is known and what is new on the studied issue? What necessitated the research problem, described in the manuscript? What is your hypothesis and aim?

MATERIAL AND METHODS: The objects of research, organization of experiments, chemical analyses, statistical and other methods and conditions applied for the experiments should be described in detail.

RESULTS AND DISCUSSION: Results of research can be presented separately from discussion or together in one paragraph. Presentation of results should be precise and without repetitions, and include the evaluation of significant differences and other parameters.

CONCLUSIONS: Present the most important consequences for the science and practice resulting from the conducted research. They should be summarized in few sentences.

ACKNOWLEDGEMENTS (if there are any)


Tables should be submitted on a separate sheet at the end of the text and must be cited in the text. They should be prepared in MS Word format  - doc and docx files (only when there is special need – in xls files). Tables are numbered in Arabic numerals according to their sequence in the text. Each column in the table must have heading and, when necessary, abbreviations should be explained in the legend.

Illustrations (maps, charts, graphs, drawings, photos, etc.) are to be referred to as ‘Figures’ and numbered in sequence. They should be as clear and free from text, presented as in format tif, png, xls, eps. Numeration and title of the figures are placed below the figure, with all necessary indications presented. It is recommended the figures to be in black and white. Provide figures and photographs with good dark and light contrast. Prepare drawings with dark, heavy lines as to be appropriate for printing.

All tables and illustrations must be cited in the text. Bulgarian contributors must send texts and titles of tables, figures, graphs and photos in Bulgarian and English.


Abbreviations may be used for other expressions provided that, when first mentioned, they are defined in full, followed by the abbreviation in parenthesis and used consistently thereafter.


In the text, references should be cited as follows: single author (Morris, 1991); two authors (Barton and Moore, 1994); more than two authors (Levi et al., 1994). When several references are cited simultaneously, they should be ranked by chronological order e.g.: (Petrovic et al., 2011; 2015) and when their publications are in the same year – alphabetically. All published works referred to in the text must be listed in the reference list and vice versa.

Reference list is arranged alphabetically (by the surname of the first author) and chronologically. When citing several publications by the same author, his individual publications are given first, followed by publications in co-authorship (with one co-author, two co-authors, etc.). It is desirable to list the names of all authors.

Names of authors and journal titles in Cyrillic or alphabet different from Latin should be transliterated into Latin and article titles should be translated into English. The original language of articles and books translated into English is indicated in brackets after the bibliographic reference (in Bulgarian = Bg, in Russian = Ru, in Serbian = Sr, in Chinese – Ch, etc.).

Example: Stoyanova, N., Antonova, V. and Serbezova, D. (2015). A study of introduced black currant varieties. Rastenievadni nauki, 52(2), 25-28 (Bg).

In transliteration, letters are replaced as follow: 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.
