In the history of the International Plant Nutrition Colloquium from its first meeting in 1954, this meeting, the 13th Colloquium, is the first to be held in Asia and will be the last in the 20th century. The 20th century has seen huge changes in the number and activities of mankind. Our population has increased from around 1. 7 billion to more than 5. 8 billion and technological innovations have completely altered our way of living. As a consequence of such rapid change, we are facing many problems including changes in our environment of a global scale. But, while food shortage has been a serious concern to mankind throughout our history, serious food shortages in the 20th century have been ...

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.
This book celebrates the dawn of the rye genomics era with concise, comprehensive, and accessible reviews on the current state of rye genomic research, written by experts in the field for students, researchers and growers. To most, rye is the key ingredient in a flavoursome bread or their favourite American whisky. To a farmer, rye is the remarkable grain that tolerates the harshest winters and the most unforgiving soils, befitting its legacy as the life-giving seed that fed the ancient civilisations of northern Eurasia. Since the mid-1900s, scientists have employed genetic approaches to better understand and utilize rye, but only since the technological advances of the mid-2010s has the possibility of addressing questions using rye genome assemblies become a reality. Alongside the secret of its unique survival abilities, rye genomics has accelerated research on a host of intriguing topics such as the complex history of rye’s domestication by humans, the nature of genes that switch fertility on and off, the function and origin of accessory chromosomes, and the evolution of selfish DNA.
The third volume in the epic military aviation series focuses on the Allied invasion of North Africa during World War II. This work of WWII history takes us to November 1942 to explain the background of the first major Anglo-American venture: Operation Torch, the invasion of French North Africa. Describing the fratricidal combat that followed the initial landings in Morocco and Algeria, it then considers the unsuccessful efforts to reach northern Tunisia before the Germans and Italians could get there to forestall the possibility of an attack from the west on the rear of the Afrika Korps forces, then beginning their retreat from El Alamein. The six months of hard fighting that followed, as t...
Owing to its considerable winter hardiness, rye is a cereal that played a major role in the feeding of European populations throughout the Middle Ages. Recent data shows that rye is grown on about 5.4 million hectares, with a world production of approximately 13 million tons. While still an important bread food in many countries, rye produced for b
