About the Author
is working as Senior Agronomist (Pulses) (equivalent to Professor) in the Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana, India. He received his BSc Agri. (Hons.) and MSc Agronomy degrees from the Punjab Agricultural University, Ludhiana, India and he was scholarship holder. He did his PhD from the University of Wales, Bangor, United Kingdom on Commonwealth Scholarship where he studied the effects of herbicides on biological nitrogen fixation in peas (Pisum sativum).He has about 20 years experience of working on various grain legumes at the Punjab Agricultural University, Ludhiana, India. His main areas of research include conservation agriculture, planting method and planting time, weed management, nutrient management, plant population and planting geometry, water management, etc. He has given very useful recommendations to farmers for raising productivity of their grain legume crops and reducing the cost of cultivation. He is actively involved in teaching of Agronomy courses to students as well as extension education programmes for farmers. He also worked with the International Centre for Agricultural Research in the Dry Areas (ICARDA) at its Regional Office for Central Asia and the Caucasus, Tashkent, Uzbekistan for one year (2005-2006) where he worked as Technical Coordinator of an Asian Development Bank funded project on 'Improving rural livelihoods through efficient water and soil fertility management in Central Asia'. I hold degrees from Pennsylvania State University (B.S. in Agronomy, 1965) and the University of Illinois [M.S. (1967) and Ph.D. (1969) in Crop Physiology]. I was employed by the University of Kentucky as a Crop Physiologist in the Plant and Soil Sciences (formerly Agronomy) Department from 1969 until I retired in 2018. I currently hold the rank of Professor Emeritus. I taught graduate courses in Crop Ecology and Principles of Yield Physiology, directed graduate students and did research in Crop Physiology and Seed Science (germination and vigor of planting seed). My research in Crop Physiology focused on understanding important physiological process [including seed growth, determination of seed number (sink size) and seed fill duration] involved in the production of yield by grain crops. Seed Science research emphasized the measurement of seed quality, the effect of the production environment on seed quality and the relationship between seed quality and field performance (seedling emergence and yield). I served as an Associate Editor for two journals (Agronomy Journal and Crop Science) and as a Technical Editor for Crop Science. Awards and honors include T.P. Cooper Research Award (1981) and the University of Kentucky Foundation Research Award (1981) from the University of Kentucky and the Seed Science (1996) and Crop Science (2006) Research awards from the Crop Science Society of America. I am a fellow of the American Society of Agronomy, the Crop Science Society of America and the American Association for the Advancement of Science.
