Wheat crop being the world''s leading cereal crop has the major role in the hunger reduction from the mushrooming world population. With the development of high yielding varieties and new technologies, the production and productivity since late 1970s has increased significantly up to this date. Still there are various yield limiting factors and one of them is the late-sowing condition especially in the agro-zones where rice-wheat system prevails. In the recent context of climate change and global warming, the production practices of many crops have been pushed to gradually change. In the rice-wheat system of cropping pattern, late sowing of wheat is becoming a common phenomenon and for any reason of late sowing, suitable variety/genotype selection with proper fertilization especially only nitrogen management can be the boon to greatly boost up the production and net returns from wheat cultivation. This book is especially important to those who are willing to conduct research activity in the field of crop science & wheat agronomy, farmers, students, academicians and development professionals.
