Concerns over environmental and human health impacts of conventional weed management practices, herbicide resistance in weeds, and rising costs of crop production and protection have led agricultural producers and scientists in many countries to seek strategies that take greater advantage of ecological processes and thereby allow a reduction in herbicide use. This book provides principles and practices for ecologically based weed management in a wide range of temperate and tropical farming systems. After examining weed life histories and processes determining the assembly of weed communities, the authors describe how tillage and cultivation practices, manipulations of soil conditions, competitive cultivars, crop diversification, grazing livestock, arthropod and microbial biocontrol agents, and other factors can be used to reduce weed germination, growth, competitive ability, reproduction and dispersal. Special attention is given to the evolutionary challenges that weeds pose and the roles that farmers can play in the development of new weed-management strategies.
Organic Olive Production Manual

Organic Olive Production Manual

Publisher: UCANR Publications
ISBN: 1601074409
Pages: 105
Year: 2007
This manual provides detailed information for growers on production issues, plant nutrition, economics, pest and weed control, management of olive wastes, the conversion process, and organic certification and registration. Using this manual you'll learn about orchard site selection considerations, irrigation needs, terrain, temperature, soil, damage from the olive fruit fly, and how these may vary for table fruit versus fruit for oil production. You'll also learn how to evaluate harvest methods an important consideration as harvest costs typically amount to half the total production cost for olives. This manual has been developed as a supplement to the Olive Production Manual, 2nd Edition. Organic growers are advised to consult both publications as they develop and refine their production systems.

Year: 1997
For years, scientists have noticed disruptions in animal breeding cycles, accompanied by increases in birth defects, sexual abnormalities and reproductive failure. Humans are not immune either, with sperm counts dropping by as much as 50% in recent decades and with women seeing a rise in hormone-related cancers, endometriosis and other disorders. This book traces the cause of these aberrations and diseases to the pervasive presence in the environment of chemicals that mimic hormones and trick the reproductive system. The conclusions are as obvious as they are inescapable - unless we make vital changes in the way we manufacture and employ the artefacts of our good life , there will be no life at all.

Experiments which in previous years were made with ornamental plants have already afforded evidence that the hybrids, as a rule, are not exactly intermediate between the parental species. With some of the more striking characters, those, for instance, which relate to the form and size of the leaves, the pubescence of the several parts, etc., the intermediate, indeed, is nearly always to be seen; in other cases, however, one of the two parental characters is so preponderant that it is difficult, or quite impossible, to detect the other in the hybrid. from 4. The Forms of the Hybrid One of the most influential and important scientific works ever written, the 1865 paper Experiments in Plant Hybridisation was all but ignored in its day, and its author, Austrian priest and scientist GREGOR JOHANN MENDEL (18221884), died before seeing the dramatic long-term impact of his work, which was rediscovered at the turn of the 20th century and is now considered foundational to modern genetics. A simple, eloquent description of his 18561863 study of the inheritance of traits in pea plantsMendel analyzed 29,000 of themthis is essential reading for biology students and readers of science history. Cosimo presents this compact edition from the 1909 translation by British geneticist WILLIAM BATESON (18611926).

Food Production and Eating Habits from Around the World

Food Production and Eating Habits from Around the World

Author: Francisco Entrena-duran
Publisher:
ISBN: 1536107751
Pages: 316
Year: 2016-12-29
This book brings together a selection of studies written by specialists from universities and/or research institutions from every continent. The processes of change in systems of production, commercialisation, and consumption of food, as well as the problems and nutritional habits analysed here, develop within the framework of the technological and socio-productive transformations experienced in many parts of the world as a consequence of the transition from traditional rural societies to the predominantly urban and industrial societies of our time. Many of these societies are affected by the fluctuations, questions, or socio-economic uncertainties caused principally by what is named globalisation. The authors involved in this volume are from a variety of backgrounds and their theoretical-analytical focuses regarding eating habits are quite diverse. However, independent of their different perspectives and scientific disciplines (Anthropology, Communication, Economy, Marketing, Medicine, Nursing, Psychology and Sociology), all of these authors are united in their concerns regarding similar food processes and problems, such as the industrialisation of food production, junk food, fast food, eating disorders, overeating, obesity, the impacts of ideal body images on eating behaviours, lifestyles and feeding, anorexia, bulimia, organic foods, healthy foods, functional foods, and so on. Moreover, in a time shaped by a worldwide standardisation of eating habits, the search for identity, specificity, or distinction through the acquisition and consumption of foods is commonplace in many chapters of the book. Likewise, these chapters show a generalised interest on the negative effects of the advertising and communications media that often drive patterns of food consumption and provoke desires for ideals of beauty and body forms prejudicial to health. As the editor states in the preface, all this occurs in an ever more modernised and globalised world in which artificial procedures of the production of industrial foods that are quite opaque to the general public become increasingly widespread. In such a world, while people's concerns over the healthiness of foods increase, we are witnessing a non-stop expansion of markets for organic food, as well as the repeated manipulation of growing consumers' preferences for certain foodstuffs that they believe are healthy or have specific natural qualities. This manipulation frequently takes place through a variety of advertisements that announce a series of industrial foods as supposedly possessing these qualities. Obviously, a priority objective of these and other advertising strategies is to increase sales in the agro-alimentary sector in a context of obvious over-production and over-supply, which in turn is translated into the stimulation of food consumption. This would help explain such developments in the current consumer society, which is explored in further detail in many chapters of this book.
