During his scientific career at ICAR-CIARI, Port Blair he worked on physiological and biotechnological management of abiotic/biotic stresses in rice, solanaceous vegetables with emphasise on salinity, drought and insect resistance. He has generated promising somaclones of rice and solanaceous vegetables with improved agro-morphological traits besides having moderate tolerance towards salinity and bacterial wilt and insect borer. He was involved in sustainable management of plant biodiversity of A&N Islands including collection, characterization, conservation and enhancement of ecologically and economically important plant species. He has got registered several indigenous germplasms of rice with NBPGR New Delhi. At ICAR Research Complex for Eastern Region, Patna he continued the work on biotechnological and physiological management of abiotic stress tolerance with special reference to submergence and drought stress conditions. Four drought tolerant rice lines with yield potential of 3.2 tons/ha have been identified for drought prone areas of eastern region of India. Besides three promising rice lines suitable for aerobic conditions with yield potential of 3.5 tons/ha were also identified. He has been associated with an ICAR network project on climate change and worked on modeling plant growth of major agricultural crops viz rice, wheat, maize and chickpea with respect to climate change in eastern region of India. He has undergone an international training on marker assisted selection at Clemson University, USA, wherein the genome of bitter melon has been mapped using AFLP and SSR markers. Besides the isolation and sequence characterization of anti-HIV (Map30) and anti-diabetic (Insulin) gene from bitter melon have also been done. Presently at ICAR-IISS, Bhopal, he is working on Nanoparticle delivery and internalization in plant systems for improving nutrient use efficiency of agricultural crops. Besides, he has been associated with projects on management for improving nutrient use efficiency of crops. Dr Elanchezhian has contributed more than 100 publications, including 46 peer reviewed research papers, 8 research bulletins, 2 edited books, 9 book chapters, 7 popular articles, 24 conference proceedings and 4 training manuals which has been widely cited throughout the scientific community. He is a recipient of Dr. GS Sirohi Award (2002) and Dr. RD Asana Award for Young Scientist (2005) given by the Indian Society for Plant Physiology. He is bestowed with Fellowship of Indian Society for Plant Physiology for contribution in the field of Plant Physiology and Cognate sciences in the year 2008. He has guided several M.Sc. students for their thesis work. He has served as expert of several important committees

Dr. A.K. Biswas was born in village Bagna in North 24 Parganas district of West Bengal on May 5, 1963. He obtained his B.Sc. (Ag.) Hons. degree in 1984 from B.C.K.V., Mohanpur, W.B. He received his M. Sc. (Gold Medalist) and Ph. D. Degrees from I.A.R.I., New Delhi and is presently working as Head of the Division of Soil Chemistry & Fertility at the Indian Institute of Soil Science, Bhopal; Madhya Pradesh. The major areas of work of Dr. A.K. Biswas have been concerning the development of farmers' resource-based integrated plant nutrient supply system in soybean-wheat system, farmers' participatory technology development of integrated nutrient management coupled with soil moisture conservation for rainfed pulse-based cropping systems, environmental impact and risk assessment of recycling of distillery and sewage effluents in agriculture, determination of sink capacity of mineralogically and physico-chemically variant soils for some heavy metal pollutants and phyto-remedial efficiency of some flowering plants to decontaminate Cd, Pb and Cr contaminated soils, delineation of nitrate contamination of groundwater in heavily fertilized and intensively cultivated districts of the country, evaluation of the effect of climate change on soil carbon stock in different agro-ecoregions of the country, development of soil organic C and N turnover model in light of C saturation and stabilization theory, development of methodology to estimate relative soil quality index to assess soil health under different agro-ecoregions of the country, and development of nano-rock phosphate for commercial utilization of low-grade indigenous rockphosphates of the country and modified urea products like oleoresin coated urea, zeoliteimpregnated and biochar coated urea. He is part of the team who developed Mridaparikshak - A Soil Testing Minilab for which patent has been applied. Dr. Biswas has contributed more than 200 publications, including 90 research papers, 20 review papers, 20 popular articles, 3 edited books, 40 book chapters and several other publications which has been widely circulated throughout the scientific community. Dr Biswas has been elected to the prestigious "Fellowship of National Academy of Agricultural Sciences (NAAS)" in 2016. He is also the recipient of the "Jawahar Lal Nehru Award" from ICAR for outstanding doctoral research in the field of Soil Science in 1992 and "The ISSS- Dr. J.S.P. Yadav Memorial Awards for Excellence in Soil Science- 2012" from the Indian Society of Soil Science, New Delhi.
