Book Description
Low and declining soil fertility are among the major factors responsible for the poor productivity of the small scale rainfed crop farming in most of the Ethiopian highlands. Thus, soil characterization and field experiment was conducted to investigate the effects of applied N and P fertilizer rates on grain yield and yield components for triticale (Triticosecale wittmack L.) production on soils of Wabela, around Debretabor area, Amhara National Regional State (ANRS). The experiment involved factorial combinations of four rates of N (0, 23, 46 and 69 kg ha-1) and P (0, 10, 20 and 30 kg ha-1) laid down in RCBD with three replications. The moist soil color of the profile was very dark brown (7.5YR 3/3), at the surface and dark grayish brown (10YR 3/3) at the bottom, with clay loam to clayey texture. The bulk density values varied with depth of the profile from 1.01 g cm-3 at the surface layer to 1.23 g cm-3 at the bottom layer. Soils of the profile indicated that the soil of the site was moderately to slightly acidic in reaction, high to medium in its total N and high in available P from the surface to the subsurface horizons.

Book Description
Triticale's days as a scientific curiosity are definitely over. Its wide acceptance as a feed, grain or forage crop, or for baking and malting, plus its high yields under marginal or stress conditions have made it an economically important crop in countries such as Poland, Germany, Australia, Portugal, Brazil, Morocco and China. This publication contains selected, reviewed, and up-to-date papers presented at the Third International Triticale Symposium held in Lisbon, Portugal, by the International Triticale Association and EUCARPIA. Among the broad spectrum of subjects addressed in these presentations are cytogenetics, biotechnology, genetic resources, breeding, agronomic practices and diseases. Also included are triticale's food, feed and forage uses, as well as its marketing processes. In a world of increasing population and decreasing agricultural resources, triticale offers a genuine solution for increasing land utilization and grain production.

Book Description
Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Book Description
Advances in Soil Science was conceived in 1982 to provide a forum for leading international scientists to analyze and summarize the available scientific information on a subject, assessing its importance and ident ifying additional research needs. This goal seems even more appropriate today. Much is known about our soil resources. The principles learned and the technology developed need to be used to increase food pro duction, particularly in developing countries, and sustain the productivity of the resource base. Advances in Soil Science fills a gap between the scientific journals and the comprehensive reference books. Scientists can delve in depth on a particular subject relating to soil science. Contributors are asked in particular to develop and identify principles that have practical applications to both developing and developed agricultures. Advances in Soil Science was established to be international in scope and cover all subjects relating to soil science. This volume certainly fulfills that objective. The first chapter is concerned with denitrification. The significance of denitrification in nitrogen use efficiency in agricultural, grassland, and forest ecosystems, and in global nitrogen cycling is now well recognized. Therefore, an understanding of denitrification is essential for the efficient use of nitrogen fertilizers and for protecting the environ ment. The second chapter looks at the effects of subzero temperatures on the physical, biological, and chemical processes. This is an important area of soil science that has not been studied in great detail.

Book Description
Agriculture depends on improved cultivars, and cultivars are developed through proper plant breeding. Unfortunately, applied plant breeding programs that are focused on cereal commodity crops are under serious erosion because of lack of funding. This loss of public support affects breeding continuity, objectivity, and, perhaps equally important, the training of future plant breeders and the utilization and improvement of plant genetic resources currently available. Breeding programs should focus not only on short-term research goals but also on long-term genetic improvement of germplasm. The research products of breeding programs are important not only for food security but also for commodity-oriented public and private programs, especially in the fringes of crop production. Breeding strategies used for long-term selection are often neglected but the reality is that long-term research is needed for the success of short-term products. An excellent example is that genetically broad-based public germplasm has significantly been utilized and recycled by industry, producing billions of dollars for industry and farmers before intellectual property rights were available. Successful examples of breeding continuity have served the sustainable cereal crop production that we currently have. The fact that farmers rely on public and private breeding institutions for solving long-term challenges should influence policy makers to reverse this trend of reduced funding. Joint cooperation between industry and public institutions would be a good example to follow. The objective of this volume is to increase the utilization of useful genetic resources and increase awareness of the relative value and impact of plant breeding and biotechnology. That should lead to a more sustainable crop production and ultimately food security. Applied plant breeding will continue to be the foundation to which molecular markers are applied. Focusing useful molecular techniques on the right traits will build a strong linkage between genomics and plant breeding and lead to new and better cultivars. Therefore, more than ever there is a need for better communication and cooperation among scientists in the plant breeding and biotechnology areas. We have an opportunity to greatly enhance agricultural production by applying the results of this research to meet the growing demands for food security and environmental conservation. Ensuring strong applied plant breeding programs with successful application of molecular markers will be essential in ensuring such sustainable use of plant genetic resources.
