Synopsis A national seminar on approaches for plant production under environmental stresses was jointly organized by Indian Society for Plant Physiology (ISPP) and Rajasthan Agricultural University (RAU) and Durgapura (Jaipur), Research Campus of the University. The present treatise is the outcome of those efforts. The volume includes contributory research papers, and review articles on various basic, application oriented (basic and applied) aspects of plant improvement and management under water deficit (drought), water excess (water logging), temperature extremes, radiation stresses, nutritional deficiencies and toxicities, soil and water salinity and alkalinity, pollution stresses, stresses caused by pathogens, weeds and angiospermic parasites. The volume is meant for plant readers, plant physiologists, crop ecologists (Agronomists), environmental biologists, soil scientists, plant pathologists, seed technologists, plant biotechnologists, molecular biologists, botanists, forest scientists and horticulturists at a common platform, so as to interact deeply with each other. The treatise includes updated scientific information on plants and crops belonging to different economic groups like cereals, millets, pulses, oil seed crops, sugar yielding plants, fruits and vegetables crops, spices, medicinal plants, forest species, plantation crops, fumitories and desert plants, etc.
