Synopsis Sustainable crop production systems are extremely meaningful in the context of dwindling natural resources and rising population pressures. Abiotic stresses are the principle sources of yield losses. Sustaining and improving crop production in abiotic stress environments is feasible with new technologies and scientific understanding. The book presents the much needed information on various hostile factors like stresses of moisture, temperature, salinity and acidity and their efficient management. The book also deals with agroforestry, different crops like cereals, millets, oilseeds and important medicinal-aromatic plants, suited to such stresses. Taking into account the latest advances in science, book covers information for students and researchers on molecular genetic approaches and male gametophyte section for abiotic stress tolerance. Chapters have been contributed by leading authorities and scientists of their own fields in specialisation.
