International Journal of Plant Production (IJPP), a peer reviewed research journal, is published by Gorgan University of Agricultural Sciences and Natural Resources (GUASNR) in yearly volumes of four issues. Special issues devoted to single topics are also published.

IJPP publishes original research papers and review papers related to physiology, ecology and production of field crops and forages at field, farm and landscape level. IJPP does not publish papers with a background in genetics and plant breeding, plant molecular biology, plant biotechnology, as well as soil science, meteorology, product process and post-harvest management unless they are strongly related to plant production under field conditions.

Papers should be original, unpublished and not being considered for publication elsewhere. Papers based on limited data or of local importance, and results from routine experiments will not normally be considered for publication. Field experiments should include at least two years and/or two environments. Papers on plants other than field crops and forages, and papers based on controlled-environment experiments will not be considered.

Preferred topics are: (1) yield gap in cropping systems: estimation, causes and closing measures, (2) ecological intensification of plant production, (3) improvement of water and nutrients management in plant production systems, (4) environmental impact of plant production, (5) climate change and plant production, and (6) responses of plant communities to extreme weather conditions.

Common rejection reasons of manuscripts are:

• The manuscript (MS) does not follow the journal's instructions for authors.
• The MS does not fall within the scope of the journal.  (for MSs with a background in genetics and plant breeding, plant molecular biology, plant biotechnology, as well as soil science, meteorology, product process and post-harvest management, and for MSs on crops other than field crops and forages).
• The MS does not contain new data or new ideas; it does not add enough to the existing knowledge.
• The MS does not reach substantial conclusions.
• The MS is based on limited data. (1-year, 1-site experiment)
• The MS is only based controlled-environment experiment.
• The MS is of local importance.
• The MS reports results from routine experiments.
