Research areas of the most cited articles at Jarq-japan Agricultural Research Quarterly:

Horticulture, Agronomy, Botany, Soil water and Biotechnology are the main subjects of interest in the most cited publications. The Agronomy research presented in the journal publications places emphasis on topics like Rice plant, Crop, Greenhouse crops, Transplanting and Seedling. While work presented in the published papers provide substantial information on Botany, it also covers topics in Gene and Sucrose.

What topics the last edition of the journal is best known for?

  • Ecology
  • Botany
  • Gene

The previous edition focused in particular on these issues:

The discussions in the journal mainly cover the fields of Agriculture, Hydrology, Fishery, Agronomy and Molecular biology. The presented studies in Dairy farming fall within the purview of Agriculture but it also intertwines with topics in Center (algebra and category theory). In Jarq-japan Agricultural Research Quarterly, Scale (ratio), El Niño Southern Oscillation and Evaporative cooler are investigated in conjunction with one another to address concerns in Hydrology research.

Issues in Fishery were discussed, taking into consideration concepts from other disciplines like Identification (biology), Thesaurus (information retrieval) and Broodstock. The journal facilitated discussions that integrated Agronomy and Supply and demand. The subject of RNA silencing, which is connected to the field of Cultivar, serves as the foundation of the Molecular biology research featured in Jarq-japan Agricultural Research Quarterly.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 47.37% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 80.00% were posted by at least one author from the top 10 institutions publishing in the journal. Another 10.00% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 10.00% of all publications and 0.00% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

  • Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
  • Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
  • Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
  • Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
  • Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

Related Online Degrees & Career Pathways

Exploring Plant Science and Agronomy offers diverse career pathways, including roles connected to healthcare and environmental sustainability. For those interested in healthcare integration, programs such as direct entry msn programs for non nurses online provide a route for individuals transitioning into nursing with a focus on science and biology foundations.

Additionally, advancing nursing credentials through programs like capella rn to bsn vs chamberlain rn to bsn can complement a background in agronomy, especially in roles that emphasize public health and environmental impacts on communities.

For more specialized interests, functional medicine nurse practitioner programs offer an interdisciplinary approach that blends plant-based medicine knowledge with patient care.

Lastly, understanding earning potential is vital when considering these avenues. Information on how much do dnp nurses make can help guide decisions about investing in further education tied to careers leveraging plant science expertise.
