Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] With the rapid development of multiple herbicide resistant weeds in crops, it is likely that an important role now exists for new grazing management strategies in farming systems to provide an integrated approach to weed management. In this thesis we examined the general hypothesis that sowing a legume of low preference by sheep relative to the target weeds of crops would improve the control of those weeds in a grazed pasture. To test this general hypothesis, legumes of low preference by Merino sheep were identified and a series of experiments conducted to determine the effect on pasture composition when these less preferred legumes were incorporated into a grazed pasture. We found a learned response that altered forage preference by sheep was important in determining the effectiveness of grazing to reduce seed set by weeds of crops. Investigations on this aspect of the grazing behaviour of sheep were a key part of this thesis. The short-term relative preference of Merino hoggets among 15 pasture legumes, 4 grain legumes and annual ryegrass was determined by offering adjacent monocultures of each of the forage genotypes to the sheep. The relative preference of the hoggets for each of the 20 forages was determined at three phases of plant growth from estimates of the amount of forage consumed. Sheep showed a low selective preference for Vetch (Vicia sativa L.), chickpea (Cicer arietinum L.), biserrula (Biserrula pelecinus L.), lotus (Lotus ornithopodioides L.) and snail medic (Medicago scutellata L.) cvs. Kelson and Sava at the vegetative phase of plant growth. An indoor method was also developed to test the relative preference of sheep among forages growing in pots. Using this method chickpea and snail medic, but not biserrula, were found to have a low relative preference by sheep at the vegetative phase.

Available in PDF, EPUB and Kindle. Book excerpt: Innovative Strategies for Managing Weeds in an Environmentally Protective Manner Successfully meeting the challenge of providing weed control without relying on dangerous chemicals that endanger the ecosystem or human lives, this compendium focuses on management strategies that reduce herbicidal usage, restore ecological balance, and increase food production. It also provides new insights and approaches for weed scientists, agronomists, agriculturists, horticulturists, farmers, and extentionists, as well as teachers and students. In the Handbook of Sustainable Weed Management, experts from Asia, Europe, North America, and Australia organize in one resource information related to weeds and their management from different ecosystems around the world that has been until now been scattered throughout the literature.. The text captures the multifaceted impacts of and approaches to managing weeds from field, farm, landscape, regional, and global perspectives. Generously illustrated with tables and figures, this book not only describes the various techniques for weed management but shows you what methods work best in a given region, or in response to a specific, invasive weed or invaded crop. Covering the full scope of modern weed science the handbook examines different aspects of weed management, including— • Cultural practices • Cover crops • Crop rotation designs • Potential of herbicide resistant crops • Bioherbicides • Allelopathy • Microorganisms • Integrated weed management In spite of advancement in technologies and procedures, weeds continue to pose a major ecological and economical threat to agriculture. Handbook of Sustainable Weed Management takes a broad view of weeds as a part of an agricultural system composed of interacting production, environmental, biological, economic, and social components all working together to find balance. This comprehensive book is a vital addition to the debate over how global weed management is changing in the 21st century. Also available in soft cover

Doole and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sowing phases of French serradella (Ornithopus sativus Brot.) pasture between extended cropping sequences in the Western Australian wheatbelt can sustain grain production through restoring soil fertility and reducing selective herbicide use. The objective of this article is to investigate the profitability of rotations involving this pasture under a variety of weed management scenarios to obtain greater insight into its value for mixed farming systems in this region. A stochastic search procedure, compressed annealing, is used to identify profitable sets of weed management strategies in a simulation model representing a large number of potential combinations of chemical and non-chemical forms of weed control. In contrast to a continuous-cropping sequence, the inclusion of a serradella phase in a rotation is profitable at high weed densities and with increasing levels of herbicide resistance. A single year of pasture in the rotation is optimal if resistance to Group A selective herbicides is present at the beginning of the planning horizon, but a three-year phase is required if resistance to multiple herbicide groups is observed. Sowing a serradella pasture twice over a two-year phase is also shown to be economically attractive given benefits of successive high weed kills.

Available in PDF, EPUB and Kindle. Book excerpt: While a good grasp of the many separate aspects of agriculture is important, it is equally essential for all those involved in agriculture to understand the functioning of the farming system as a whole and how it can be best managed. It is necessary to re-assess and understand rain-fed farming systems around the world and to find ways to improve the selection, design and operation of such systems for long term productivity, profitability and sustainability. The components of the system must operate together efficiently; yet many of the relationships and interactions are not clearly understood. Appreciation of these matters and how they are affected by external influences or inputs are important for decision making and for achieving desirable outcomes for the farm as a whole. This book analyses common rain-fed farming systems and defines the principles and practices important to their effective functioning and management.

This book was released on 2009-08-25 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an ever-increasing human population, the demand placed upon the agriculture sector to supply more food is one of the greatest challenges for the agrarian community. In order to meet this challenge, environmentally unfriendly agroch- icals have played a key role in the green revolution and are even today commonly recommended to circumvent nutrient de?ciencies of the soils. The use of ag- chemicals is, though, a major factor for improvement of plant production; it causes a profound deteriorating effect on soil health (soil fertility) and in turn negatively affects the productivity and sustainability of crops. Concern over disturbance to the microbial diversity and consequently soil fertility (as these microbes are involved in biogeochemical processes), as well as economic constraints, have prompted fun- mental and applied research to look for new agro-biotechnologies that can ensure competitive yields by providing suf?ciently not only essential nutrients to the plants but also help to protect the health of soils by mitigating the toxic effects of certain pollutants. In this regard, the role of naturally abundant yet functionally fully unexplored microorganisms such as biofertilizers assume a special signi?cance in the context of supplementing plant nutrients, cost and environmental impact under both conventional practices and derelict environments. Therefore, current devel- ments in sustainability involve a rational exploitation of soil microbial communities and the use of inexpensive, though less bio-available, sources of plant nutrients, which may be made available to plants by microbially-mediated processes.
