1. INTRODUCTION

In the field of Library and Information Science bibliometrics/ Scientometrics as it is presently known is of recent origin through its roots could be traced to a study made 85 years ago in 1917 since then it has come a long way and attained much importance and significance for library and information managers. Researchers in bibliometrics has also given birth to a couple of other terms scientometrics and informatics which are used today in place of bibliometrics Earlier the term statistical bibliography was also used for it while Ranganathan prepared to call it Librametry all these terms are the same. Bin Li et al. (2020)Bibliometrics has practice applications in the evaluation of library operations and surveys through statistical techniques to make the quantitative analysis possible.  There are some Bibliometrics techniques are used they are to study research trends and growth of knowledge in the field of Library and information science, to estimate comprehensiveness of secondary periodicals, to identify users of different subjects, to identify authorship trends in documents on various subjects, to measure the usefulness of retrospective and current awareness services. 

 

2. Scope Methodology

The present study is limited to Scientometric analysis and titles word linkage in doctoral thesis of vegetable pathology during the period of 2007-2019.  Data has been collected from Krishikosh Website. The citation technique is adopted for the study there are 12 thesis and their 2,327 references were analyzed according to citation method. The collected data were tabulated presented, analysis and interpreted with the help of tables and graphs. The present data is entered in MS Excel sheet. According to AACR2 cataloguing code. The ranking of periodicals are checked country of publications in SCIMAGO Website and there were 06 thesis titles selected for linking of words in universe of knowledge.  Garga & Tripathib (2018)

 

3. Objectives of the study

·        To know Year wise Submission of Doctoral thesis in Vegetable Pathology

·        To find out Average number of Citations in each thesis 

·        To verify Types of documents cited by researchers

·        To know Authorship pattern of citations and degree of collaboration

·        To know Ranking of Periodicals

·        To find out Geographical wise distribution of journal articles

·        To verify Age wise distribution of journal references.

It determining the degree of collaboration in quantitative term the formula given by K.Suramanyam (1982) was used .

Formula                 NM

                          _______

                             NM+NS

 

Where C= Degree of Collaboration

NM = Number of Multi Authored papers

NS=Number of Single authored papers

In the present study

NM=1,176

NS= 232

Thus C=0.83
