Book Description
Grain yield and end-use quality are the most important characteristics for hard red winter wheat (Triticum aestivium L.). Improvement of grain quality characteristics of grain from a given growing season and location requires systematic understanding of the genotype chosen, the production environment, and also knowing the consequence of rate and time of individual production packages such as seed treatment, seed rate, nitrogen (N) fertilization, and foliar fungicide applications. The objectives of this study were to: identify the effects of seed rate, genotype, and N top-dressed on yield, agronomic characteristics, and end-use quality of winter wheat; and to determine the effects of seed treatment and flag leaf foliar fungicide application on yield and agronomic characteristics of wheat cultivars. Two experiments were conducted at Havelock, near Lincoln, NE and the High Plains Agricultural Lab (HPAL), near Sidney, NE in 2014 and 2015 using randomized complete block design with split factorial arrangement. Overall foliar N increased grain yield, grain protein concentration, other baking quality indicators such as flour water absorption, peak height, tail area, weakening slope, and depressed grain volume weight, mixing time, and tolerance. Similarly, increased seed rate improved grain yield, seed weight, grain volume weight, flour yield, mixing time, and mixing tolerance. Increased seed rate reduced grain protein, flour water absorption, tail area, peak height, and weakening slope. Seed treated with EverGol Energy and Gaucho showed improved seedling emergence, leaf greenness, grain yield, and seed weight. Application of foliar fungicide at flag leaf stage improved grain yield, seed weight, and leaf area. Among the six genotypes evaluated, ‘Settler CL’ and ‘Freeman’ had the highest overall grain yield. The study demonstrated the importance of seeding rate and the existence of a wider than expected tolerance range for seeding rate. The study also demonstrated the importance of in-season nitrogen top dress and foliar fungicide application to increased winter wheat grain yield and grain quality in Nebraska. However, further research is recommended to fine-tune the factors and interdependence of response in relation to a specific location, season or the prevailing weather condition, and the specific attribute of the genotype seeded.

Book Description
Genetically uniform cultivars in many self-pollinated cereal crops dominate commercial production in high-input environments especially due to their high grain yields and wide geographical adaptation. These cultivars generally perform well under favorable and high-input farming systems but their optimal performance cannot be achieved on marginal/organic lands or without the use of external chemical inputs (fertilizers, herbicides and pesticides). Cereal breeding programs aim at evaluating candidate lines/cultivars for agronomic, disease and quality traits in a weed free environment that makes it impossible to identify traits conferring competitive ability against weeds. Moreover, quantification of competitive ability is a complex phenomenon which is affected by range of growth traits. Above (e.g. light) and below (e.g. water and nutrients) ground resources also influence competitiveness to a greater extent. Competitiveness is quantitatively inherited trait which is heavily influenced by many factors including genotype, management, environment and their interaction. Sound plant breeding techniques and good experimental designs are prerequisites for maximizing genetic gains to breed cultivars for organically managed lands. The brief is focused on breeding wheat for enhanced competitive ability along with other agronomic, genetic and molecular studies that have been undertaken to improve weed suppression, disease resistance and quality in organically managed lands. The examples from other cereals have also been highlighted to compare wheat with other cereal crops.

Book Description
Organic Crop Breeding provides readers with a thorough review of the latest efforts by crop breeders and geneticists to develop improved varieties for organic production. The book opens with chapters looking at breeding efforts that focus on specific valuable traits such as quality, pest and disease resistance as well as the impacts improved breeding efforts can have on organic production. The second part of the book is a series of crop specific case studies that look at breeding efforts currently underway from around the world in crops ranging from carrots to corn. Organic Crop Breeding includes chapters from leading researchers in the field and is carefully edited by two pioneers in the field. Organic Crop Breeding provides valuable insight for crop breeders, geneticist, crop science professionals, researchers, and advanced students in this quickly emerging field.

Book Description
Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book series gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Book Description
Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
