SCOPE

The journal welcomes original research papers from authors worldwide that make significant experimental, theoretical, methodological or production oriented contributions to agricultural science. Manuscripts should advance scientific knowledge through novel findings, innovative methodologies, or practical applications relevant to agricultural systems. The journal adopts a broad definition of agricultural science to encourage interdisciplinary research and comprehensive coverage of the field, including socio-economic aspects that contribute to sustainable agricultural development. The journal publishes high-quality research in the following areas: Agronomy, animal science, soil science, climate and environment related to agricultural aspects. Agronomy covers plant breeding, crop physiology, crop production, agricultural biotechnology, plant protection (including pests, diseases and weeds), seed science, precision agriculture, cropping systems, and postharvest technology. Animal sciences include animal breeding and genetics, nutrition, reproduction, physiology, health and disease, livestock production systems, and related biotechnological applications. Soil Sciences cover aspects of mineralogy, classification, land evaluation, chemistry, fertility and nutrient management, fertilizers, soil conservation, physics, microbiology and sustainable soil management. Climate and Environment: climate change and its impacts on agriculture, agroclimatology, environmental management, natural resource conservation, agricultural ecosystems, water management, and sustainable agricultural practices. The journal is published biannually with two issues released each year in June and December.

MANUSCRIPT STRUCTURE

Manuscript covers Title, Abstract, Introduction, Materials and Methods or Approach/Methodology, Results and Discussion, Conclusion, Acknowledgment, and References. Appendices may be included if necessary. Each section is given the capital letter. Further subsections are given subheading in the lowercase with capital for each word.

The title should be concise, factual, informative, and should contain not more than 15 words in English and Indonesia. For non-Indonesian authors, the title in the Indonesian language will be handled by editors. The name(s) of the author(s) should appear below the title, followed by the full address at the time the work was carried out, and their present addresses, if they are different. Indicate author’s affiliation address with a superscript number and give asterisk (*) for the corresponding author who will handle the manuscript during review and revision processes. Provide email address for the corresponding author.

The abstract summarizes the study in one paragraph of not more than 250 words in English and Indonesia (Indonesian abstract is not applied for non-Indonesian authors). The abstract should describe briefly and concisely the problem, the objective, the methods, significant data, principal findings, and conclusions. Only standard terms, scientific nomenclature and accepted abbreviations should be used.

Keywords appear immediately after the abstract of maximum 5 words. These keywords allow the readers to easily access the publication.

Introduction

The introduction should place the study in a regional or international context, provide a brief review of the relevant literature, identify the existing knowledge gaps, describe the novelty of the study and clearly state the objectives and the importance of the research.

Materials and Methods

Materials and methods or approach/methodology should provide a brief description for already published methods supporting by references. New methods should be described in detail to allow other workers to repeat or apply the procedures.

Results and Discussion

The results and discussion could be presented either as a single section (preferred) or as separated sections. Figures and tables should be used in the results section wherever appropriate to present the findings clearly and effectively. The discussion should interpret and explain the significance of the research findings, but not repeat the results. Discussion should relate the findings to the research objective, methodology, key results and discuss their implication for advancing knowledge, technology and innovation.

Conclusions

Conclusions should be drawn with regard to the title, objectives, discussion of the findings and supported by the data. Suggestion could be given if necessary

The use of artificial intelligence (AI). The Indonesian Journal of Agricultural Science (IJAS) supports the responsible and transparent use of artificial intelligence (AI) in scholarly publishing. Generative AI refers to artificial intelligence technologies capable of creating new content, including text, images, audio, code, and synthetic data. Examples include ChatGPT, Microsoft Copilot, Gemini, Claude, and DALL·E.

Generative AI and other AI-assisted technologies ("AI tools") are increasingly used in research and scholarly publishing and can provide valuable support when used responsibly. However, these technologies must never replace human expertise, critical thinking, scientific judgment, or ethical responsibility. These guidelines are intended to promote transparency, research integrity, and the ethical use of AI throughout the publication process.

Authors are not permitted to submit manuscripts that are wholly or substantially generated by generative AI tools. Authors remain fully responsible for the originality, accuracy, integrity, and scientific content of their manuscripts. AI tools may be used for limited purposes, such as: improving grammar, spelling, readability, and language quality; and assisting with literature searches and information discovery.

Any use of AI-assisted technologies should be carefully reviewed and verified by the authors. AI tools must not replace the authors' intellectual contribution, critical analysis, interpretation of findings, or scientific judgment.

Editors and reviewers must maintain the confidentiality of all unpublished manuscripts and associated materials. Therefore, they must not upload unpublished manuscripts, reviewer reports, or confidential editorial content to generative AI tools. Editors and reviewers may use AI tools only for limited purposes, such as language editing and literature searches, provided that no confidential or unpublished content is disclosed to third-party AI systems.

IJAS will continue to monitor developments in AI technologies and scholarly publishing and will revise these guidelines as standards, best practices, and technologies evolve.

Basic checks of grammar, spelling, and punctuation do not need a declaration statement. However, when an AI tool makes substantive changes to sentence structure or organization of a part of the text, this should be disclosed. Authors are recommended to use the following format for their declaration:

Title of section: Declaration of generative AI and AI-assisted technologies in the manuscript preparation process

Statement: During the preparation of this work, the author(s) used [NAME OF TOOL / SERVICE] in order to [REASON]. After using this tool/service, the author(s) reviewed and edited the content as needed and take(s) full responsibility for the content of the published article.

Authorship: Authors should not list AI tools as an author or co-author, nor cite AI tools as an author. Authorship implies responsibilities and tasks that can only be attributed to and performed by humans. Each (co-) author is accountable for ensuring that questions related to the accuracy or integrity of any part of the work are appropriately investigated and resolved, and authorship requires the ability to approve the final version of the work and agree to its submission.

The editors of this journal generally will not consider changes to authorship once a manuscript has been submitted. It is important that authors carefully consider the authorship list and order of authors and provide a definitive author list at submission. Changes can only be made prior to acceptance, and only if approved by the journal editor. This includes additions, deletion, or rearrangement of author names. This journal does not allow authorship changes after acceptance. This includes additions, deletions, or the rearrangement of author names, including changes to the corresponding author.
