Research productivity of pepper from 2005-2014: a bibliometric analysis.

Author:Thirumagal, A.
  1. Introduction

    Pepper is widely used in traditional Indian medicine and as a home remedy for relief from sore throat, throat congestion, and cough. Pepper is a native of South and South East Asia. It is referred as "Black Gold" and used as a form of Commodity Money. Pepper was grown particularly in Southern Thailand, Malaysia and Kerala. The study is confined to a period of ten years from 2005 to 2014 covered in the database PubMed only. The key word "Black pepper" or "Piper nigrum" or pepper is used to download the results. The results 2475 were saved in the text file format. The data were analysised with the toolbox named as Bibexcel. This is developed by Olle Persson. This software is very useful for analysing bibliographic data. S Aswathy and A.Gopikittan are analysis the "Journal of Space graft and Rockets". It covers various parameters like growth pattern, authorship pattern, distribution with regard to subject, year, institution and geographical area. (1)

  2. Need for the Study

    Pepper is a Dravidian word. Peppercorns are often classified on their place of origin. Two types come from India's Malabar Coast and Tellicherry. "Journal of Chemical Information and Computer Sciences (JCICS) was found out the apex journal in this subsection for the last 30 years.In the subject of chemical information and computer sciences (CICS) bibliometric approach was used to survey the state-of-the-art of research." (2) C.Baskaran examined the research growth, relative growth rate and doubling time of publications, institution wise and ranking of authors in research productivity of Graph Theory during 2004-2011. (3) Plants modulate defense signaling networks in response to different biotic stresses. The study evaluated the effect of a phloem-sucking aphid on plant defense mechanisms in pepper during subsequent pathogen attacks on leaves and rhizosphere bacteria on roots. The findings of this study show that aphid feeding elicits plant resistance responses and attracts beneficial bacterial populations to help the plant cope with subsequent pathogen attacks. (4) A valuable source of information for improving our understanding of the underlying molecular mechanisms by which pepper leaves become symptomless following infection with geminiviruses. The identification of ortho logs for the majority of genes differentially expressed in recovered tissues in two major solanaceous crop species provides the basis for future comparative analyses of the viral recovery process. (5) Crop cultivation provides critical ecosystem services in arid lands with the plant root system acting as a "resource island" able to attract and select microbial communities endowed with multiple PGP traits that sustain plant development under water limiting conditions. (6) Kochujang is a traditional Korean fermented food that is made with red pepper, glutinous rice, salt, and soybean. Kochujang is fermented by naturally occurring microorganisms through which it obtains various health-promoting properties. (7)

  3. Objectives

    R Kumaragurupari, Pamela Sieving and Prajna Lalitha were conduct a bibliometric analysis of Indian ophthalmic papers published from 2001 to 2006 in the peer-reviewed journals, to assess productivity, trends in journal choice, publication types, research funding, and collaborative research. (8) On that basis pepper analysis also done. Dried ground pepper has been used since antiquity for both its flavour and as a medicine. Oil can be extracted from the crushing of the pepper. This oil is used for Ayurvedic massage and beauty products. The major objectives of this study are:

    * Find out the Quantum of research done

    * Find out the Distribution of Research Productivity according to Country

    * Find out the research by Language

    * Find out the Publication Types and Authorship Pattern

    * Find out the keyword and Co-word analysis

    * Application of Bradford Law of Scattering in Pepper Research Publications

    * Application of Zipf Law in the Pepper Research Publications

    * Find out individual Authors Pepper Research, RGR and DT

    3.1 Quantum of literature published on Pepper during 2005-2014:

    The literature has been classified in Table 1 according to year of publication. It is found that there is a gradual growth of literature in the subject of study by year after year. There is a gradual growth for research in Pepper.

    3.2 Distribution of Research Productivity according to Country

    Distribution of contributions of Pepper by country and year wise is presented in Table 2. It is seen from the table that United States has produced 842 records ranking in the first position, England (564) in the second position and Netherland (210) third positions respectively. Indian contributions (45) have been ranked in the 9th position.

    3.3 Distribution of Research Production by Language

    The below table shows the dissemination of Pepper literature by language. The scholarly communication is effected through English language in almost all the countries irrespective of the native language of the country. Rojas Sola and AguileraGarcia...
