Biography

Dr. Jatindra Nath Kalita is an internationally recognized agricultural chemist, tea scientist, inventor, and innovator from Assam, India, with over four decades of experience in tea research and agricultural technology. He earned his M.Sc. in Chemistry with First Class and completed his Ph.D. from Dibrugarh University, conducting pioneering research at the world-renowned Tocklai Tea Research Institute.

Throughout his career, Dr. Kalita has represented India at international ISO (International Organization for Standardization) meetings in Germany, China, and the United Kingdom, contributing to the development of global tea quality and food standards. His scientific work has been published in numerous national and international journals, reflecting his commitment to advancing tea science and sustainable agriculture.

Dr. Kalita is the inventor of two patented technologies that have significantly improved quality control in the tea industry:

  • JNK Iron Filing Extractor (Patent No. 358264) – a machine designed to continuously remove iron filings from tea during the manufacturing process.
  • Equipment for Estimation of Iron Filing in Tea (Patent No. 347799) – an innovative system for accurately detecting iron contamination in tea.

These inventions received international recognition through the prestigious NASA Tech Briefs "Create the Future" Awards (2014), where both technologies were recognized for their innovation and practical impact. His patented solutions have helped improve tea safety, quality assurance, and manufacturing efficiency, making them valuable contributions to the global tea industry.

Beyond research, Dr. Kalita has also developed the PLANTAMIN series of plant nutrient formulations and has actively promoted rural development, scientific awareness, and sustainable agricultural practices. His lifelong dedication to science, innovation, and society continues to inspire researchers, tea professionals, and young innovators across India and beyond.

Social Life & Community Impact

Inspired by his father's legacy, a lifelong commitment to rural development.

Inspired by his father, Dr. Kalita associated himself with social works for the development of rural society and the economic upliftment of the local community. On his personal initiative, he founded OPARUP (Organization for Poverty Alleviation of Rural Underdeveloped People).

With active participation from government organizations and renowned personalities, OPARUP undertook several social initiatives — including installing sanitary latrines for needy households with support from CAPART (Council for the Advancement of People's Activity and Rural Technology), and organizing motivational speeches across the area.

Mushroom cultivation was promoted through a Central Culture Centre on the OPARUP campus, producing trainees who went on to export mushrooms internationally. A periodical named OPARUP was also published — the first of its kind from a rural setting to receive an ISSN (International Standard Serial Number).
