These three volumes deal with the diseases of primarily cultivated annual edible oilseeds, i.e., peanut (groundnut), rapeseed-mustard, sesame, sunflower, safflower, and nigerseed. It is reliably believed that this book will be of great help not only to students, reseachers, and teachers but also to agricultural extension workers, field workers, seed growers, and seed crop inspectors, and subsequently to the farmers, to achieve the over-all objective of increase in oilseed crop yields throughout the world.
