The book is divided into two parts, kharif crops and rabi crops, covering as many as 48 crops. It contains the latest, authoritative and readily usable information about the cultivation techniques, varieties, nutrient/water/weed management along with specific climatic/soil requirements of all the crops. It is essentially a teaching and study material as it is written conforming to ICAR syllabus, strictly considering the limitations of the students and the teachers. Information on each crop is chosen in such a way that it is readily understandable by the undergraduate students and can be explained by the teachers in 22 weeks of a semester. Unnecessary detailing and research information has been avoided. Photographic illustrations of the crops are given to enable the students to understand the morphology of the crop clearly. Related terms, concepts or recent advancements in each crop are highlighted in the box. For a group of related crops, model questions are also given to visualise the probable questions on each crop. An attempt has been made to include the latest statistics from FAO and other global and Indian sources. Points to remember given at the end of each chapter enable the students to have a quick recap of the topic before examination. Further, many general topics, related to field crops, have been covered in eight separate brief chapters, to ensure that the students understand crop-related topics.

By the year 2050, the world's population is expected to reach nine billion. To feed and sustain this projected population, world food production must increase by at least 50 percent on much of the same land that we farm today. To meet this staggering challenge, scientists must develop the technology required to achieve an "evergreen" revolution-one

While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa ration, particular attention has been given to advances in plant-breeding theo ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un changed. These objectives are (1) to review essential features of plant re production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant breeding objectives with emphasis on the importance of proper choice of objec tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.

Running a productive agriculture system has always been about having the right tools and the know-how to pursue optimization and efficiency. In the 21st century, the case can be made that the agriculturist's most important tool is not the cultivator, but the computer. While you still need to know how to adapt to the day-to-day challenges of land an

This new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology.
