Short Communications Short communications should report completed work, not preliminary findings. They are an alternative format for describing smaller pieces of work; they should not be more than 8 pages (double spaced) and should not contain more than two figures, tables or combinations. Their preparation should follow the format of full length manuscript. 7. Registration of Crop Variety Registration of crop variety can also be considered provided that the following conditions are met. •Letter of confirmation from host institute that a variety is developed by the applying author(s) and institute(s). •Letter of acceptance of a variety by a National Variety Release Committee. •A variety should not be older than two years since its acceptance by a National Variety Release Committee. •Description of a variety (morphological, agronomical, genetical, agro-ecology, environment, etc.) should be provided briefly in double spaced 4-5 pages. •It should have title, authors, affiliations and detail description of a variety. 8. Submission of Manuscript Three hard copies and a soft copy should be sent to the Editorial Office, East African Journal of Sciences, Haramaya University, PO Box 116, Haramaya, Ethiopia. A complete mail, fax, telephone and email address of the corresponding author is necessary. Once a manuscript is accepted, a hard copy of the revised manuscript along with a soft copy saved on CD-RW should be sent to the Editorial Office. Text, tables and figures should be saved on separate files. Each figure of the accepted manuscript should be saved separately as Text Image Format (TIF). The editors are not responsible for any loss or damage to manuscripts that might happen during submission; hence authors are advised to retain original copy of their manuscript.
