The objective to the background of this publication has been to follow an equilibriated and realistically inter-disciplinary approach for enhancing productivity with sustainability. Hence, research papers and review articles contained in this publication have focused on vital aspects relating to productivity of crops and plants. Scientific information on practical aspects of osmoconditioning, thermoconditioning and invigoration of seeds for enhancing seed yield and quality have been documented alongwith dry permeation technique. Usefulness of traditional farming practices and their compatibility with modern agrotechniques have been included. Practical utility along with economic viability of PGRs applications in field, forestry and horticultural crops have also been embodied along with some potent and new plant growth regulators. A special review article on the role of plant physiology in biotechnological innovations has also been processed. Seed biological, phytohormonological and biotechnological aspects of crops like wheat, pea and other pulses, oilseed crops like groundnut and mustard, fruits, vegetables, medicinal plants, ornamental plants, spices, MPT (multi-purpose trees) like neem are the subjects of some research papers and review articles. Emphasis on micropropagational biotechnology has been given to obtain virus-free seedlings of few plants. Scientists, teachers, scholars, scientific managers, planners and administrators who have their interests in botanical, agribotanical, forestal, environmental, biotechnological, seed physiological, seed pathological, horticultural aspects shall certainly be benefitted by the scientific information contained in this book.
