Yield, storability, processing quality and pest management of potatoes, several sets of experiments to investigate the effect of some plant extract and essential oils on the growth, yield attributes, storability, mechanical injures, physiological disorders, processing related characters and insect pest management, and to find out the effect of various application techniques of essential oils at ambient temperature on decay, weight loss and chips and French fries quality are also include in this book. This book also aims to provide a novel anti-sprouting agent for inhibiting growth of potato tubers and processing quality and to identify of terpenoids which may be used to inhibit tuber sprouting as compared to CIPC as a conventional chemical inhibitor. The experimentation and their respective procedures mentioned in this work, are carried out at favorable conditions under very good supervision, and the results are thus obtained, by analyzing the quality parameters on well-equipped laboratories.
