INTRODUCTION
Foods, health and education are the basic and necessary needs for
day to day life of people all over the world. If basic needs are not
sucient, the people of the country will be poor in all respects
and those countries also could not be developed. Agriculture
refers to crop and animal husbandry, aquaculture, sheries, and
forestry for food and non-food products. Agriculture was the
key development of the practice of living in one place for a long
time i.e., rises of human civilization. To make human civilization
better, some agricultural revolutions took place around the
world such as British Agricultural Revolution, Green Revolution,
Neolithic Revolution, etc. (Wikipedia, 2024). e development of
agriculture nearly 12,000 years ago which has changed the way
humans lived. Wildgrains were collected and eaten from at least
104,000 years ago. By around 9500 BC, the eight Neolithic founder
crops like wheat, barley, peas, lentils, bitter vetch, chickpeas,
and ax, etc. were cultivated in a large area in the Eastern
Mediterranean region of West Asia and core territory of Middle
East. Ricewas domesticated in China by 6200 BCwith earliest
known cultivation from 5700 BC. Rice was also domesticated
in West Africa and cultivated by 1000 BC (Wikipedia, 2024a).
Traditionally, Asian countries have the largest share in rice
production worldwide. Over 513 million metric tons of milled
ricewas produced in the last harvesting year globally. As per the
most recent ocial data, it is learnt that quantity of production
of rice was over 208 million metric tons in 2022, and China was
the world’s leading paddy rice producer, followed by India and
Bangladesh (FAO, 2022; Shahbandeh, 2024).
is scientometric study is based on biography and bibliography
of research publications of Dr. Chaudhury. ere are many
bibliometric analysis carried out by several library and
information scientist on eminent persons/ scientists either living
or death from dierent disciplines. Mostly have been highlighted
by the author in his dierent publications (Koley and Sen, 2016)
and by others (Rao, 2013; Dutta, 2019; Sidlingappa et al., 2023; Teli
and Maity, 2021). Notwithstanding, no such study on Chaudhury,

SHORT BIOGRAPHY OF DR. ABED CHAUDHURY
Early Life and Education
Chaudhury is an Australian-Bangladeshi renowned geneticist
as well as rice researcher. He is also looked at one of the most
distinguished leading international gures in modern biology. He
was born in a Bengali Muslim family, the Z amindars of Kanihati in
Hajipur Union, Kulaura, Moulvibazar District of Sylhet Division,
Bangladesh on 1 February 1956. His father was Abdul Mannan
(Ibrahim) Chaudhury and mother was Haza Khatun. He passed
Madhyamik from the Moulvibazar Government High School, and
higher secondary (HSC) from Notre Dame College, Dhaka. He
completed his B.Sc., Honours in Chemistry at the University of
Dhaka, Bangladesh in 1979, and his M. S. (Molecular Biology
and Chemistry) from University of Oregon, Eugene, USA in 1981.
Aer that, he received his PhD degree in Molecular Biology
from Organic State Institute of Molecular Biology, University of
Oregon, Eugene, USA in 1984. His thesis title is ‘Homologous
Recombination in Escherichia coli’ (Everybodywiki.com, 2023;
Bengal Byte, 2022; Kanihati.com, 2003; Knowledge Hub, 2020).
Chaudhury currently lives in Australia.
Professional Career
Chaudhury, the gene scientist started professional career as a
teacher and researcher at dierent institutions like National
Institute of Health (NIH),USA, Massachusetts Institute of
Technology (MIT), USA and while here, he conducted post
doctoral research in Food and Nutrition and Plant Biology. He
has devoted his professional knowledge in Rice Breeding and has
led research programmes in Australian Centre for International
Agricultural Research (ACIAR) and International Rice Research
Institute (IRRI). He was a visiting scientist at Ecole Normale
Supérieure of France (Bengal Byte, 2022; Knowledge Hub, 2020).
He led a team of scientists at Australian National Science Agency,
and under his supervision dierent research activities were done
there. Chaudhury also was associated with several institutions for
research works. Besides, he is a co-founder of Genofax, a global
biotechnology company which acts in developing AI technologies
for genomic medicine. Chaudhury tries to begin its big data
driven medication in Bangladesh (Dhaka Tribune, 2024;Tasnim,
2023). Before coming into contact with Genofax, Choudhury
has many outstanding research works in crop breeding, climate
mitigation, and genetics globally, including notable contributions
to the agricultural sector of Bangladesh (Tasnim, 2023).
He has memberships of dierent professional societies namely
Genetics Society of America, Inter society of Plant Molecular
Biology, American Association of Advancement of Science,
New York Academy of Science, etc. Chaudhury was committee
members of several organizations such as CSIRO Forum
committee (1995-2000); Plant Industry Panel (1992-1994);
Sexual Plant reproduction association as Australia Representative
(2000-2001); the International Plant Genetic Resource Institute,
Rome, Italy. He also worked as a grant-reviewer such as regular
reviewers of grants of NSF, USDA, US small business grants,
NIH, USA and ARC of Australia; ad-hoc adviser to the Austrian
Government in summer, 2000; and reviewers of all major
international journals specializing in Plant Science (Kanihati.
com, 2003).
Research Contributions
Aer completing his PhD in 1984, he joined as Head of Scientic
Innovation at Loam Bio, Australia; Chief Scientist and Director
at Vita Grain Pte. Ltd., and Vita Rice; Principal Scientist at
Syngenta Australia and New Zealand. Before that, he worked
as Senior Principal Research Scientist (Plant Biology) at the
Commonwealth Scientic and Industrial Research Organization
(CSIRO) in Australia for 19 years where he pioneered the work
on Fertilization Independent Seed (FIS) (Knowledge Hub, 2020).
He established the foundation of work on polycomb group genes
in seed development. He has also contributed to the development
of many varieties of crops that are important for human nutrition
such as black rice, black tomato and others glucose reducing
rice. He also worked at Soil Company (Bengal Byte, 2022; ATSE,
2022). When he led as a postdoctoral scientist at HHI and MIT,
USA, he discovered a new gene namely ‘Rekdi’ through genetic
recombination which drew an immense attention and interest
in research and practices in the USA and Europe in 1980s. Aer
that he created three Fertilization Independent Seed (FIS). His
FIS formula commenced an ‘era of apomixes’. e mutants can
produce fractional seed without fertilization. ere are rst
characterized genes involved in apomixes, a method of making
seed without the father (Knowledge Hub, 2020; Bengal Byte,
2022). is was his one of the revolutionary innovations. Out of
many innovations, ‘red-maize’ was one of the most prominent
innovations. It is a drought-tolerant with more nutritious than
rice; and resistant to cancer diseases. He also invented dierent
types of new rice like Haza-1, Jalalia, Tanha and Doon. Recently,
in 2023, he has developed ‘Panchabrihi’- uncommon paddy seed
yields ve times throughout the year, and ‘Kanihati 1 to 16’, a new
variety of rice that is cultivated in Amon season. It has named
aer his homeland. is newly discovered rice can be cultivated
during short time and is produced huge in quantity (Alam, 2023).
Dr. Chaudhury is a researcher on heredity. He also invented red
rice and colored corn. Colored corn, which is anti-diabetic and
anti-cancer, is discussed worldwide. He is currently studying
on high yielding rice production and future food security in
Australia (Gfmdhaka.com, 2022). Chaudhury’s research activity
has spanned more than 40 years in the eld of molecular biology
and allied. Many students have been awarded PhD degree under
his guidance including Julie Glover (ANU), Amy Chin Atkins
(ANU), omas Choi (Melbourne University), and Ming Luo
(ANU) (Kanihati.com, 2003).

Koley: A Scientometric Portrait of Dr. Abed Chaudhury
Panchabrihi: a New Discovery of Rice Production
Method
Aer 20 years working as a leading rice researcher at Australian
National Research Organization, he discovered nearly 300 paddy
seeds. He went Australia and stayed there for working purpose,
yet he has been at the agriculture farm in his birth place ‘Kanihati’
for testing and cultivating paddy seeds that he discovered. us,
it is going on. en, Chaudhury started to think why once
harvested rice plant could not produce many times like as mango
or jackfruit. From this thought, he began new research journey for
today’s Panchabrihi. At the beginning, he continued to separate
those rice seeds from which again new sheaf of paddy were grown
aer cutting and harvesting once ripping paddy. In this way, 12
types of paddy seeds were found by him. He started cultivation
with the 12 types of seeds and observed that these gave regular
yielding second time. en, again, he tried to get yielding third
time and he also succeeded in that. But except four types of seeds
(out of 12) the rest were ruined aer giving four time yielding.
He went on study on the four types of seed for ten years using
two methods. One is hybridization between local seed and high
yielding seeds. Second one is hybridization between local seed
and local hybrid seeds. us, aer long eorts with the farmers of
Kanihati, Chaudhury discovered ‘Panchabrihi’ that gave yielding
during three seasons Boro, Aus and Amon or throughout the year
(Bengal Byte, 2022). ‘Panchabrihi’ is a newly invented uncommon
paddy. It is a historic discovery of agricultural research that is very
much needed mainly in the rice eating countries for meeting food
shortage. Especially that’s how natural calamities like ood and
drought are took place in Bangladesh and India every year; it will
relieve the food crisis of the growing population of the countries.
ough, it can be cultivated worldwide. So, ‘Panchabrihi’, a new
type of rice production method that is considered to be a landmark
discovery of 21st century in a genetic research. e ‘Panchabrihi’
was named by Dr. Chaudhury, is combination of two terms-
‘Pancha’ meaning ‘ve’, and ‘brihi’ that means ‘paddy’. Reasons for
this type of naming are that if this paddy seed is once planted in
the eld, it will yield ve times throughout the year and during
three seasons. It is worth noting that 'Panchabrihi' cultivation
allows for the production of one variety of Boro, two of Aman,
and two of Aush from one rice tree. In Indian states like Assam,
West Bengal, Odisha, and Bangladesh, rice is usually sown thrice
in a year such as Aus, Amon, and Boro. Aus is sown in summer
along with pre-monsoonal rains and harvested in autumn. Aman
is sown in the rainy season (July-August) and harvested in winter.
Boro is sown in winter and harvested in summer.
Research Implications
is variety of rice will yield ve times a year from one plant.
Aer rst time, its production will be reduced in the second
time; the third time this yield is much higher than previous
productions. According to the explanation of Chaudhury with
an example, if the rst time 40g of rice is produced per unit of a
plant, it will be 20g in the second time, followed by 50 to 60g in
the third time, 20g in the fourth and 15g in the h time. is rice
seed yields three-time higher production than regular separate
cultivation of Boro, Aus and Amon (Billah, 2023). It needs not
to completely remove the rice plant aer the rst harvesting. As
per the description of the scientist, methods of cultivation has
described below (Gfmdhaka.com, 2022). He engaged farmers
in his birthplace Kanihati in Sylhet, Bangladesh to build a rural
innovation hub i.e., farmer-led innovation platform for increasing
biodiversity and generation of climate-compliant crop, which
recently led to the innovation of 'Panchabrihi', a new type of rice
cultivation method (Tasnim, 2023). For many years he has been
working enthusiastically to reform his home-place Kanihati into a
rural hub of intellectual activity especial attention to educational
improvement. To give a shape his ideas, he initiated a project
namely “Kanihati Experiment,” for demonstration of social,
intellectual, agricultural and environmental transformation
(Bengal Institute, 2024; Rice News Today, 2024). For this purpose,
he has built an agriculture farm in his native place ‘Kanihati’.
Procedures of cultivation of ‘Panchabrihi’ are given below as
described by the scientist.
Seasons or Throughout the Year
‘Panchabrihi’ paddy is harvested for three seasons- Bora, Aus and
Aman or the whole year.
Materials and Methods
e scientist described the procedure for the cultivation of the
rice. First time for boro season, it is sown in January (winter).
Aer 110 days, during rst week of May, it is harvested rst time.
en aer 45 days, in July, it is started second time production.
Next, aer every one and half months, third, fourth- and h-time
production will be began respectively. It must be noted that with
proper irrigation and care, use of urea fertilizer in right ratio, the
crop grows to a height of 85 cm to one meter in 110 days. Every
time aer production, the paddy is to be cut at a height of 35 cm
from the ground.
Production
For the rst time, the production of harvested paddy may be four
tons per hectare. Since then, the yielding per hectare is two-three
tons. All varieties can be yielded about 16 tons per hectare.
Easily Seed Preservation
Farmers themselves can collect seeds from the harvested paddy
and easily preserve them for future cultivation.
Research Limitations
e ‘Panchabrihi’ yields ve times a year. It cannot have impressed
local scientists of Bangladesh Rice Research Institute (BRRI) or
Bangladesh Agricultural Research Institute (BARI). e scientist
wants to cultivate this paddy seed in Bangladesh and minimize

Koley: A Scientometric Portrait of Dr. Abed Chaudhury
the crisis of food of the growing population of the country. Few
experts raise questions about his discovery not yet peer-reviewed
or no publication of the ndings of this discovery in any journal
(Billah, 2023; Rice News Today, 2024). e description of his
innovation, he demonstrated in presence of several journalists
at a seminar organized by the London-Bangla Press Club on
October, 2023 (Alam, 2023). However, some body takes it positive
and it is in discussion and criticism in Bangladesh. It is just ying
on dierent social Medias. Hope that its true facts will come in
front of all and start its cultivation in Bangladesh and other rice
producing countries.
Future Research
Chaudhury is cultivating ‘Panchabrihi’ in homeland in
Bangladesh for bringing interest of such paddy seed. He also
tries to introduce it among the farmers outside the Bangladesh.
As it is produced more than one time, it may solve the shortage
of foods especially in the rice-eating countries. Not only is that
it also environment friendly. Bangladesh as well as West Bengal,
Assam is aected by ood, drought many years and the paddy
cultivation using this method may supply of rice in the period of
crises at any time.
Chaudhury’s Talents beyond Scientic Research
Works
Dr. Abed is a multitalented gure. Beyond his talent in scientic
research, he is a powerful thinker, science writer, activist, and a
man of literature. He has written so many non-ction books and
several books of poetry in both Bangla and English. His rst book
Shoibal O Ontorikko (Bengali): an anthology of poems published
by Dibya Prokash in 1999. His books include the Blueprint of
Experience; Human Genome: Man of Genes, Dream, Existence,
River, and other Poems, etc. in Bengali, and Paradigm Shi, the
Gene revolution, the Future of Food in English. In addition, his
other books are namely Nirbachito Kobita, Anguished Rivers and
Other Designs, Shopno Sotta Nodi and Onnanno Kobita. Besides,
he also has written columns such as Durba Sisir O Porbotmala,
and Priyo Australia online news portal (Everybodywiki.com,
2023; Knowledge Hub, 2020). For his varieties of talent, some are
said that he is “A Man of Sheer of Brilliance” (Knowledge Hub,
2020).

DATA ANALYSIS & DISCUSSION
Year-and-Age wise Authorship Patterns
Table 1 shows year and Chaudhury’s age wise papers during
1984-2023. His rst collaborative paper appeared in 1984 when
he was 29 years old and his productive life spanned 40 years.
Out of 68, there are four single authored papers 1 in 1993 (age
38), 2 in 2001 (age 46), and 1 in 2005 (age 50), and remaining
64 are multi-authored papers. Out of them, he has produced 19
papers as rst author, 10 as second-author, 8 as third author, 6
as fourth author, and 10 as h author and so on. He has two
papers, one in 2023 (age 68) and year not found for other under
mega-authorship. He led the team as rst author in as many as
19 papers. In all he has published 45 papers as co-authors. In
his 40 years of productive life, he has no publication in 1987-88,
1990, 2003-04, 2006, 2011-12, 2104, 2016, and 2018-22. From
the table, it is also observed that the scientist has published 54
(79.41%) papers, more than 50% when he was 50 years of his age.
When he completed 60 years, more than 90% papers have been
published by him. He produced 3 papers in his retried period.
Year of publication has not identied (YNF) for one paper. Over
all 290 co-authors were involved in research work along with the
scientist. His productivity peaked at the age of 46 in the year 2001.
It is observed that Chaudhury has contributed a maximum
number i.e., 8 of outstanding contributions at the age of 46, i.e.,
in the year 2001, followed by 7 at the age 44 in the year 1999, 5
papers each in the years 1998 and 2000 at the age of 43 and 45.
He has published 4 papers each in the years 1994 (age 39), 1996
(age 41) and 2002 (age 47). ree papers have been contributed
by him in 2005 at the age of 50 and so on.

Koley: A Scientometric Portrait of Dr. Abed Chaudhury
Degree of Collaboration
It is observed that during 40 years of his productive period, the DC
has its maximum value 1 only in 23 years i.e., no single-authored
paper has been published in 23 years (Table 1). ere is DC value
equal to 0.5 for one year i.e., 1993; the same greater than 0.5 for
two years, 2001 (DC 0.75) and 2005 (DC 0.67). In all, DC Value
is 0.94.
Annual Growth Rate (AGR) of Research Articles
Table 2 shows annual growth rate and cumulative annual growth
rate of publications. To measure the AGR, the following formula
can be used, that is AGR= (End value – First value) x 100/ First
value (Jain & Meera, 2022). For example, here rst one has been
worked out for hints, for the years 1984 to 1985. So, here, End
value corresponding the year 1985 =2, First value corresponding
the year 1984= 2. erefore, AGR = (2-2) x 100/2= 0 and so on.
In case of annual growth, in 1997 and 1998, there is an increase of
400% from 1 to 5 papers. In 1993-94 and 1995-96, a 100% growth
from the previous year. Aer 1998, it has gradually declined to
28.57% in the year 2000; again, it has increased. In cumulative
annual growth (CAG), it was seen that during the starting years,
the increase was 20 to 100% till in 2001. Aer that CAG varies
from 1 to 6%. It can be mentioned that inference in number of
publications exists between 1 to 8.

Relative Growth Rate (RGR) and Doubling Time (DT)
RGR and DT are two important indicators in bibliometric study.
RGR is the increment in the number of research article per unit of
time. Table 3 counts RCR and DT from 1984-2023. RGR and DT
have been measured from 1984 to 2023. RGR is calculated year
wise. e following formula has used for nding the value of RGR
(Mondal and Raychoudhury, 2017; Jain and Meera, 2022; Sawale
and Mete, 2021; Mondal, 2021):
RGR = W2 – W1 / T 2 – T1
Where,
W1 = Natural log of initial number of research articles;
W2 = Natural log of nal number of research articles;
T1 – T2 = Unit dierence between the initial year (time) and nal
year (time).
Here, time dierence is one year. So, formula shortly is:
RGR = W2 – W1
e corresponding DT can be measured as DT = 0.693/ RGR,
one by one (Mondal and Raychoudhury, 2017; Jain and Meera,
2022) and enumerated values for DGR and DT have been shown
in Table 4. e DGR has been decreased from 0.693 in 1985 to
0.015 in 2023 during the time span of 38 years. During the years,
the DT has been increased from 1985 (1.000) to 2023(46.200). All
over its curve has been up and down in the time span of 38 years
(Figure 1).
Non-Collaborative Papers
Table 4 shows non-collaborative publication pattern and time
span for publication. Chaudhury produced a largest number of
non-collaborative papers i.e., 68 throughout his life. Five-author
collaboration has created in the largest number of papers, i. e.,
16 with the time span of 18 years. Two-author papers totaling 13
was published in a time span of 26 years. Four-author papers i.e.,
9 have seen the light of day in a time span of 23 years. Besides,
eight-author 6 papers took 27 year of time spans. ere are 5
three-author papers which have produced in a time span of 28
years. Year of publication for one paper could not be ascertained.

Status in Byline of Authors
Table 5 depicts the status of Chaudhury in the byline of authors in
his 68 collaborative papers. He appears as the rst author as many
as 19 cases. He occupies the second and h place in 10 cases
each, third place in 8 papers, forth position in 6 papers, and so on.
He has placed 9th, 13th and 14th position in 1 case each.
Publications by Quinquennium
e quinquennium publication data of Chaudhury has been
counted in the Table 1 and graphical representation has been
shown in Figure 2. e highest publications has gured 24 during
1999-2003, at the age range of 44 to 48 followed by 16 papers
during 1994 to 1998 (age range 39 to 43; 7 contributions during
2004 to 2008 (age range 49-53); 6 papers each during 1984 to
1998 (age range 29 to 33) and 1989 to 1993 (age range 34 to 38)
respectively. More than 76% papers have been contributed by
the scientist during the rst four quinquenniums (age range 29
to 48). It is observed that the author’s productivity has increased
with the time span of 20 years of his active productive age and
then declines with age. His productivity peaked during the fourth
quinquennium (Figure 2) when he has published 24 papers
during age range 44 to 48.
Prolic Collaborators
Table 6 enlists name wise prominent co-authors’ publications

co-authors 3 papers each; another a category of 21 authors has
published 2 papers each along with the scientist. ere are 112
authors published 1 paper each.
Lotka’s Law Testing
As Lotka’s Law, 60% of total author should have 1 paper each, 15%
will have 2 papers each, 7% should have 3 papers each and so on.
For the data set from this study, here 75.17% have 1 paper each
that is ≥60%; and 14.05% have 2 papers each, not equal to 15%;
3.36% have 3 papers each that could not reach to 7%, the standard
percentage as per law, and so on. erefore, the data set does not
validate the Lotka’s law.

Citation Analysis
Highly Cited Scholarly Works and Citation Growth Rate (CGR)
Table 8 enlists highly cited 23 articles (out of 68) which have
received more than 100 citations in GS and counts rate of
CGR in online three indexing databases Google Scholar (GS),
ResearchGate (RG), and PubMed (PM). From the data set,
it is observed that the article “Fertilization independent seed
development in Arabidopsis thaliana” has ranked rst in GS
(631citations), third in PM (177 citations) and no citation
received in RG for the paper; corresponding CGRs are 22.54
in GS, and 6.32 in PM. e second one “Miniseed3 (MINI3), a
WRKY family gene, and HAIKU2 (IKU2), …, are regulators of seed
size in Arabidopsis” has cited by others 600 times (CGR 30.00) and
ranked 2nd in GS, 485 times (CGR 24.25) and ranked 2nd in RG,
and 242 times (CGR 12.12) and ranked 1st in PM. It is remarkable
that the second paper shows a rise in the rate of CGR in GS, RG
and PM respectively. Over all, amount of citation received and
rate of CGR of most of the papers are high in GS throughout the
study followed by RG and PM. us, his top 23 scholarly works
have considered for CGR, and a CGR graph has been drawn in
the Figure 3 with the values found in GS, RG and PM.
Citations Received Pattern
Table 9 shows citation received Chaudhury and his collaborative
authors according to the range of citation distribution. It is
seen that maximum number of papers i.e., 23 have received the
citation range more than100 in GS, 25 papers’ and 31 papers’
citation range =0 in RG, and PM respectively. Fourteen (N14)
papers in GS have not received any citations whereas 17 papers
in RG and 8 papers in PM have received the citation range more
than 100 respectively. It also enumerates that rates of citation per
article are 11.91 in GS, 78.35 in RG and 31.16 in PM. On average
he has received 202.55, 133.20 and 52.98 per year in GS, RG and
PM respectively.

Koley: A Scientometric Portrait of Dr. Abed Chaudhury
CONCLUSION
Chaudhury’s Panchabrihi is a groundbreaking discovery of
the 21st century for human kind. Its multiple productions may
reduce food crisis in Bangladesh, India, Australia and other
rice-feeding countries. e new and uncommon paddy seed is
more productive and so the scientist expects it will be very helpful
for Bangladeshi farmers. Because most of the areas in Bangladesh
are ooded and draughty and hence cultivation cannot be
possible properly there. It can be solved rice crisis especially in
Bangladesh and India. Weather more and less is same in both
the countries. Panchabrihi grows huge number of roots in the
ground which help to produce carbon in soil that can improve the
quality of the soil. is method he himself has been applying in
his native village along with the local farmers of Bangladesh. For
this purpose, there is an agricultural rm in his village ‘Kanihati’.
Cultivation of panchabrihi is cost saving method than multiple
harvested seeds as it is once planted and yields ve times with
a good quantity throughout the year from the same plant. He
has already generated nearly 300 new types of paddy seed. He
has started his research works at the grass root level where poor,
hardworking people i.e., farmers are living and thus civilization
grows from the agriculture at the village level. Where agriculture
is the foundation of the countries like Bangladesh, India, etc.,
his works in agriculture science is very much remarkable and
Panchabrihi is also a revolutionary discovery in the world.
Chaudhury, a scientist, writer, poet, well-wisher and social
reformer, in a word, a multi-purposeful ideal man who can only
look at the people living at the grass root level, fell their crisis
and up li their level using agricultural products. It is considered
a landmark innovation in terms of preventing food crisis
throughout year. us, for his outstanding works, Chaudhury is
regarded as one of the most leading gures in modern biology. He
has manifold experiences in genetics, crop breeding, molecular
