This book focuses on the soil and environmental resources and how to utilize them under Egyptian conditions to achieve tolerance to environmental abiotic stresses, i.e., drought, heat, salt, pollutants, and biotic stresses such as disease resistance. Further, it explores ways to increase productivity, improve the quality of field crops, and reduce the food gap. The application of modern technologies is an essential mechanism for improving crops' productivity through laser, seed technology, mycorrhiza, and biotechnology to enhance the yield of genotypes in sustainable farming systems. Therefore, this book discusses fundamental ways to increase productivity under various environmental circumstances. The book reflects the enormous potential held by horizontal
