Book Description
The low productivity of the rice-wheat cropping system in Nepal is associated with a low efficiency of applied mineral N in rice. The aquatic fern Azolla was used to reduce N losses via ammonia volatilization from the flooded lowland rice in farmers' field conditions in Nepal. The Azolla cover changed the floodwater chemistry, thus reducing ammonia volatilization losses. The use of Azolla in combination with Urea increased rice yields by 15% and reduced urea-N losses from 17-38% to 2-8%. A combined use of Azolla and urea is a viable option to enhance the productivity of rice-wheat systems in Nepal.

Book Description
Climate change has intensified in recent decades, which has affected crop production as well as facilitated the emergence of new diseases and insect pests, causing serious threats to agriculture. Farmers have mostly taken a crop-based approach to insect pest management (IPM); the authors of this new volume, however, take the unique approach that IPM based on specific cropping systems is more efficient, resulting in reduced cultivation costs, increased yield and profitability, and decreased residue from crop produce and products. This volume presents the results of research done by crop protection scientists on integrated pest management in diverse cropping systems based on rice, wheat, maize, pulses, food legumes, oilseeds, groundnut, potato, and other horticulture crops. With chapters written by well-known and experienced scientists in their fields, this volume provides in-depth knowledge on integrated pest management in conjunction with an array of specific cropping systems, taking into consideration all the elements, including the crops, crop sequences, spatial and temporal aspects of managing an agricultural system, and other aspects. This volume will be valuable for entomologists, plant pathologists, and agronomists, as well as for farmers—both small and industrial sized, agricultural extension centers, faculty and students, and many others involved with crop cultivation.

Book Description
According to the United Nations, 77 million people are expected to face water shortage by 2025, if people continue to use water at the current rate. More water than available would be needed to grow the worlds food during the next decade. As a result of scarcity of water, global annual food production losses could reach 350 million tons by 2025.Di

Book Description
This book provides a timely review of concepts in plant disease management involving microbial soil suppressiveness and organic amendments. Topics discussed include the impact of suppressive soils on plant pathogens and agricultural productivity, the enhancement of soil suppressiveness through the application of compost and the development of disease suppressive soils through agronomic management. Further chapters describe diseases caused by phytopathogens, such as Pythium, Fusarium and Rhizoctonia, interaction of rhizobia with soil suppressiveness factors, biocontrol of plant parasitic nematodes by fungi and soil suppressive microorganisms.

Book Description
Under ongoing climate changes, natural and cultivated habitats of major crops are being continuously disturbed. Such conditions impose and exacerbate abiotic and biotic stressors. Drought, salinity, flood, cold, heat, heavy metals, metalloids, oxidants, irradiation, etc. are important abiotic stressors, while diseases and infections caused by plant pathogens, such as fungal agents, bacteria and viruses, are major biotic stresses. In many instances, stresses have become the major limiting factor for agricultural productivity and exert detrimental role on growth and yield of the crops. To help feed an ever increasing world population and to ensure global food security, concerted efforts from scientists and researchers have identified strategies to manage and mitigate the impacts of climate-induced stresses. This book, summarizing their findings, is aimed at crop improvement beyond such kind of barriers, by agronomic practices (genetics, breeding, phenotyping, etc.) and biotechnological applications, including molecular markers, QTL mapping, genetic engineering, transgenesis, tissue culture, various 'omics' technologies and gene editing. It will cover a wide range of topics under environmental challenges, agronomy and agriculture processes, and biotechnological approaches. Additionally, fundamental mechanisms and applied information on stress responses and tolerance will be discussed. This book highlights problems and offers proper solutions for crop stress management with recent information and up-to-date citations. We believe this book is suitable for scientists, researchers and students working in the fields of agriculture, plant science, environmental biology and biotechnology.
