India is the second largest producer of vegetable next to China. Cowpea is one of the most important leguminous vegetable crop. The area is increasing day by day under Cowpea crop, however, no suitable variety/ genotype is available to fulfill the present demand in case of the maximum yield with better quality. If we consider, the world scenario of cowpea production, India is far behind in productivity. So the increase in the production of cowpea is being possible by using best variety in most suitable time. Considering the productivity trends there is a need to increase the cowpea production by introducing new genotypes by sowing at different times. This book contains valuable knowledge in crop science, plant genetics, crop physiology, horticulture, and other relevant disciplines. This book will be of significant interest to advanced undergraduate and post-graduate students of Horticulture, Plant physiology, Crop science, Plant genetics and rural development as well as NGO workers and farmers.
