My humble Academic and Technological contributions 

 

1) Published a Key Research Paper under single authorship-- Guha, P. (2006). Betel leaf: The Neglected Green Gold of India. J. Hum. Ecol. 19 (2):87-93. It has been cited by 148 authors as on today. This is the most widely cited paper related to Betel leaf.

 

2) Achieved a Patent (No 202600 dtd. 2.3.2007) on A System For Extraction of Essential Oil From Plants/Parts Thereof Bearing Essential Oil. This technology has been transferred  more than  TEN Govt. and private concerns through SRIC, IIT, Kharagpur on consultancy mode as well as through Krishi Mela and Trainings. Clients also iinclude IIHR, Bangalore. This instrument has been recommended as a basic research tool for comparison of quality parameters of plants in terms of essential oil content. A large number of companies are manufacturing essential oil of betel leaf. Earned over Rs 30 lacks by consultancy services and technology transfer to Govt & Non Govt organizations on Betel leaf Technology.

 

3) Transferred technology for preservation of fresh betel leaves  to the Govt of Tripura (Dept of Agriculture, Agartala) and  a Pvt. party namely, Sri Krishna Cold Storage, Kaktia Bazar, Mecheda, East Midnapore (WB). The latter has started commercial trial since 20.4.2016 and the Govt of Tripura is expected to start commercial trial from July 2016. Several Big Organizations (Both Govt & Pvt.) are also in contact with us for obtaining the same technology. This is first time in the world as far as known.

 

4) M/s Amritasya Enterprises Pvt. Ltd, Baleswar, Orissa has commercialized technology for manufacturing natural herbal mouth freshener with our technical support in consultancy mode (They have paid ₹ 13 lakhs to SRIC, IIT, Kgp). This is first time in the world as far as known.

 

5) Developed 14 Novel Technologies so far related to betel leaf which is ready for commercialization  (Three have already been commercialized).

 

6) Longest number of years devoted to betel leaf research, education and commercialization since 1995.

 

7)  Brought funds about ₹ 1.7 crorers so far from 33 Research and Consultancy Projects, out of which about  ₹ 52 lacks were related to betel leaf (of which about ₹ 30 lakhs from Consultancy projects from Govt., NGO & Pvt. organizations).

 

8) Govt of Tripura is establishing Tripura Institute of Betel Leaf Technology (Centre of excellence) with my initiative and co-operation (Building construction completed in April, 2016). This is first time in the world.

 

9) Chaired sessions on Betel Leaf Technology in IIHR, Bangalore and BAMETI, Patna.

 

10) Presented several Lead papers on Betel Leaf Technology related aspects at AAU, Jorhat; IISR, Calicut;  CSVTU, Bhilai and CARI, Port Blair.

 

11) So far guided (completed) 34 M. Tech and 10 B. Tech Students mostly on Betel Leaf Technology. A PhD student  submitted Thesis on Forest Management  and degree awarded during 2010. Another PhD student  submitted Thesis  on Food Preservation with Essential Oil of Betel Leaf on July 31, 2017 and 05 more scholars are still working on different aspects of betel leaf along with 12 M.Tech. and 04 B.Tech students this year (2017).  

 

12) Developed New Method of minimizing losses of Onion during storage for three months.

 

13) Introduced a new subject Food quality and safety standards for UG, PG and PhD students since 2010.

 

14) Carried out fundamental research on Biology and management of the Aquatic weeds, Chara spp which infested over 0.4 million hectares of paddy fields only in West Bengal.

 

15) Two of my humble research papers cited in publications of FAO and IRRI (one each).

​

16)Developed New management practices and pioneering knowledge about Weed Biology including survival mechanism of an obnoxious aquatic weed (Chara spp) of waterlogged rice field infesting about 0.4 million ha area only in West Bengal.This work has been referred by the FAO, Rome, Italy (Weed Management in Rice by Auld & Kim,1996) as well as by the IRRI, Philippines(Prog. in Rainfed lowland Rice by IRRI, 1986).

 

17) Developed water management practices for wheat, mustard, gram and lentil crops in Kangsabati Command Area in Bankura District (WB) and trained the farmers.

 

18) Developed Agro-technology for enhancing production of Betel leaf and disseminating it in consultancy service mode.

 

19)India is the largest producer of Betel leaves(production worth about 9000 million rupees/year) of which about 10% goes waste every year. Technology Developed for minimizing wastage of Betel Leaf by new methods (preservation, processing, product development and oil extraction). NABARD has sanctioned financial assistance for setting up a self-sustainable Betel Leaf Preservation Unit at Kaktia Bazaar in East Midnapore District (WB). This unit has been inaugurated  on  20th April 2016.

 

 20) Developed technology for minimizing wastage of ripe Palmyra Palm Fruits by developing appropriate method of storage, processing and products.
