Overview

Top Research Topics at Japanese Journal of Crop Science?

The journal focuses on Agronomy, Botany, Horticulture, Rice plant and Cultivar. The journal connects research in Agronomy with the related topic of Nitrogen. While Botany is the focus of Japanese Journal of Crop Science, it also provided insights into the studies of Crop and Elongation.

It concentrates on Horticulture topics that focus on Ripening and Germination. It explores research in Dry matter and the adjacent study of Dry weight.

  • Agronomy (50.19%)
  • Botany (27.28%)
  • Horticulture (17.50%)

What are the most cited papers published in the journal?

  • High temperature-induced sterility in indica rices at flowering (369 citations)
  • Male Sterility Caused by Cooling Treatment at the Young Microspore Stage in Rice Plants : V. Estimations of pollen developmental stage and the most sensitive stage to coolness (153 citations)

Research areas of the most cited articles at Japanese Journal of Crop Science:

The most cited papers are organized to address concerns in the fields of Agronomy, Botany, Rice plant, Photosynthesis and Horticulture. The journal papers address concerns in Agronomy which are intertwined with other disciplines, such as Ripening and Nitrogen. The most cited articles with studies in Rice plant featured incorporate elements of Sterility and Stage (hydrology).

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

  • Botany
  • Ecology
  • Enzyme

The previous edition focused in particular on these issues:

The journal generally zeroes in on subjects such as Agronomy, Horticulture, Cultivar, Yield (engineering) and Seeding. It facilitates discussions on Agronomy that incorporate concepts from other fields like Diversity (politics) and Insect. While work presented in Japanese Journal of Crop Science provided substantial information on Horticulture, it also covered topics in Morphology (linguistics) and Sterility.

Issues in Cultivar were discussed, taking into consideration concepts from other disciplines like Aphanomyces, Root rot, Glucan, Trimming and Sugar beet. Some problems in Yield (engineering) that were presented in the journal overlapped with concepts under Colocasia esculenta, Vegetation Index, Water balance, Shoot and Water content. The Seeding research discussed in it can contribute to the expansion of the discourse in closely related subjects like

  • Paddy field and related Fertilizer, Coated urea, Yield (chemistry) and Remote sensing (archaeology),
  • High yielding that connect with fields like Temperate climate, Production cost and Sowing..

The most cited articles from the last journal are:

  • High-Yielding Ability of F1 Hybrid Rice Varieties “Hybrid Togo Series” in the Direct Seeding on Well-Drained Paddy Field in Temperate Regions (0 citations)
  • Differences in the Sterility of Japanese Rice Varieties under Short-day Conditions and Seasonal Changes (0 citations)
  • Analysis of Soybean Seed Yield Using Vegetation Index Captured with UAV (0 citations)

Papers citation over time

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, 54.05% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 41.18% were posted by at least one author from the top 10 institutions publishing in the journal. Another 35.29% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 17.65% of all publications and 5.88% 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.
