This book deals with cotton-wheat production system (CWPS)which occupies an important place in the agricultural economy of several south Asian countries. Instability of Cotton-wheat production system (CWPS) has increased particularly during the post transgenic hybrids phase mainly because of these hybrids calling for intensive crop management being cultivated under all situations specially resource poor conditions leading to violent fluctuations during adverse years and thereby affecting the socio-economic status of these developing countries. This book may be helpful to researchers, students and extension scientists who are working on transgenic cotton or systems. Shortfalls are always a vital part of any manuscript, so suggestions or others re-searchable issues on CWPS, will be always welcomed and appreciated for further improvements.
