Book Description
Weeds hold an enigmatic and sometimes-controversial place in agriculture, where they are generally reviled, grudgingly tolerated, and occasionally admired. In most cases, growers make considerable effort to reduce the negative economic impact of weeds because they compete with crops for resources and hinder field operations, thereby affecting crop productivity and quality, and ultimately the sustainability of agriculture. Weed control in production agriculture is commonly achieved through the integration of chemical, biological, and mechanical management methods. Chemicals (herbicides) usually inhibit the growth and establishment of weed plants by interfering with various physiological and biochemical pathways. Biological methods include crop competition, smother crops, rotation crops, and allelopathy, as well as specific insect predators and plant pathogens. Mechanical methods encompass an array of tools from short handled hoes to sophisticated video-guided robotic machines. Integrating these technologies, in order to relieve the negative impacts of weeds on crop production in a way that allows growers to optimize profits and preserve human health and the environment, is the science of weed management.

Book Description
Rice is cultivated throughout the world under submerged conditions. The high water requirements and the heavy pesticide load used in rice paddies worldwide have resulted in contamination of associated surface water, such as streams, ditches, rivers and lakes. The uniform risk assessment approach which has been developed for other crops is not applicable to rice paddies, because of the specific conditions applied to rice cultivation. Pesticide Risk Assessment in Rice Paddies: Theory and Practice fills the gap in information on this subject. Written by experts, this book summarizes the methods used for pesticide risk assessment in rice paddies, the limitations and problems encountered and future developments. It also examines the various agronomic, pesticide application and risk assessment approaches used in different rice cultivated zones in Asia, America and Europe and is an essential reference for those working in this area.* The only up-to-date book dealing with pesticide risk assessment in the flooded conditions of rice paddies* Offers guidelines on the use and application of existing modeling tools, specific for rice cultivation* Presents the differences and similarities in rice cropping systems and how these relate to pesticide risk assessment

Book Description
This book focuses on the conventional breeding approach, and on the latest high-throughput genomics tools and genetic engineering / biotechnological interventions used to improve rice quality. It is the first book to exclusively focus on rice as a major food crop and the application of genomics and genetic engineering approaches to achieve enhanced rice quality in terms of tolerance to various abiotic stresses, resistance to biotic stresses, herbicide resistance, nutritional value, photosynthetic performance, nitrogen use efficiency, and grain yield. The range of topics is quite broad and exhaustive, making the book an essential reference guide for researchers and scientists around the globe who are working in the field of rice genomics and biotechnology. In addition, it provides a road map for rice quality improvement that plant breeders and agriculturists can actively consult to achieve better crop production.

Book Description
This book is open access under a CC BY-NC 2.5 license. This book offers 19 detailed protocols on the use of induced mutations in crop breeding and functional genomics studies, which cover topics including chemical and physical mutagenesis, phenotypic screening methods, traditional TILLING and TILLING by sequencing, doubled haploidy, targeted genome editing, and low-cost methods for the molecular characterization of mutant plants that are suitable for laboratories in developing countries. The collection of protocols equips users with the techniques they need in order to start a program on mutation breeding or functional genomics using both forward and reverse-genetic approaches. Methods are provided for seed and vegetatively propagated crops (e.g. banana, barley, cassava, jatropha, rice) and can be adapted for use in other species.

Book Description
The grass or Poaceae family includes all cereal crops and forage grasses. Hence, they play a significant role in the economy of both the developed and developing world. Similar to other crop types, grasses are continuously challenged by a variety of environmental constraints. These constraints include a variety of biotic and abiotic stresses, and an enabling environment, which mainly refers to policy-related issues that affect productivity. In this book, the importance of selected cereal crops and grasses as well as associated constraints are presented. In addition, techniques proven to improve the productivity of these groups of crops are discussed. The techniques include variety development, soil and crop management practices, and biological control of fungal pathogens using different types of bacterial strains.

Book Description
Rice is a staple crop in many coastal and non-coastal areas of the globe and requires a large production area. With the increasing trends in population , it is pivotal to increase the production of this important crop for sustainability. The introduction of high-yielding rice cultivars through molecular breeding is one of the possibilities that can ensure sustainability. Additionally, development of new biotic and abiotic stress-resistant cultivars with higher nutritional value can revolutionize the rice industry.
