Book Synopsis Weed Seedbank Dynamics and Composition of Northern Great Plains Cropping Systems by : Kristin Suzanne Bates Harbuck
Download or read book Weed Seedbank Dynamics and Composition of Northern Great Plains Cropping Systems written by Kristin Suzanne Bates Harbuck and published by . This book was released on 2007 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: We found that all studied species declined to low levels over two years with little difference due to depth and density. Wild oat seeds were more germinable in buried treatments. We concluded that seedbanks of these species will decline quickly with lack of seed inputs. Objective 3 was carried out in four spring wheat and four tilled fallow fields at Montana State University's Arthur Post Agronomy Farm. Surface seed predation was measured at six times during the growing season for four weed species. We observed that predation levels did not differ between wheat and fallow fields for three of four species. We conclude that seed predation can represent an important loss in Montana. Objective 4 was carried out in spring wheat production fields near Big Sandy, Montana. Weed seedbanks were sampled along a range of aboveground weed diversity points over two years. Weed seedbank composition and characteristics did not differ between cropping systems, but did between years. We conclude that weed seedbank diversity and richness may vary based more upon yearly environmental factors than the management system.
Book Synopsis Winter Cover Crop Impacts on Weed Dynamics in Eastern and Central Nebraska by : Elizabeth Ann Oys
Download or read book Winter Cover Crop Impacts on Weed Dynamics in Eastern and Central Nebraska written by Elizabeth Ann Oys and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reducing tillage in cropping systems causes weed management to be dependent on chemical and cultural methods for weed control. Over time, herbicide-resistant weeds have developed due to the continuous selection pressures from herbicides, particularly in the Midwest Corn Belt. Integrated weed management strategies, such as cover crops, can be used to mitigate some of these issues. Cover crops are primarily known for their soil health benefits, but there is evidence that cover crops can suppress weeds. However, less research has been done at the field-scale level to address cover crop impacts on the weed seedbank and aboveground weeds during the growing season. In response, two experiments were designed to investigate above and belowground weeds in eastern and central Nebraska. The soil seedbank was germinated from soil samples and weed density and biomass were measured at two points during the growing season. Our results show that cover crops did not influence the total seedbank density, but increased the density of Amaranthus spp. seeds in the seedbank. Aboveground, reductions in weed density and biomass reductions occurred at two sites. More importantly, larger pigweed seedbank densities in the cover crop treatments were not expressed aboveground, signifying cover crop suppression of the weed seedbank through reduced germination withdrawals. This research provides insight on above and belowground weed dynamics under cover crops and shows that cover crops may be a viable integrated weed management tool for Amaranthus spp. management and mitigating risks of herbicide resistance over time by preventing seedbank withdrawals through germination.

Book Synopsis Conservation Agriculture and Climate Change by : Ritesh Saha
Download or read book Conservation Agriculture and Climate Change written by Ritesh Saha and published by CRC Press. This book was released on 2022-12-08 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional tillage and burning crop residues has degraded the soil resource base and intensified soil degradation with concomitant decrease in crop production capacity. The emerging issue of global warming coupled with greenhouse gases emissions has further aggravated the scenario. Conservation agriculture helps in reducing many negative effects of conventional agriculture such as soil erosion, soil organic matter decline, water loss, soil physical degradation, and fuel use. Conservation Agriculture helps improve biodiversity in the natural and agro-ecosystems. Complemented by other good agricultural practices including the use of quality seeds, integrated pest, nutrient and water management, Conservation Agriculture provides a base for sustainable intensification of the agricultural production system. Moreover, the yield levels in Conservation Agriculture systems are higher than traditional intensive tillage systems with substantially less production costs. This book provides comprehensive understanding of the subject with topics related to climate change mitigation strategies, approaches and impact of conservation agriculture on natural resource management.

Book Synopsis Integrated Weed Management for Reduced Weed Infestations in Sustainable Cropping Systems by : Rodrigo Werle
Download or read book Integrated Weed Management for Reduced Weed Infestations in Sustainable Cropping Systems written by Rodrigo Werle and published by Frontiers Media SA. This book was released on 2023-10-30 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weeds pose a major challenge to the sustainability of agricultural production systems, causing significant crop yield, economic and environmental losses. Chemical weed control tactics play a major role in modern weed management, maintaining the productivity of diverse cropping systems, reducing yield losses and facilitating conservation agriculture. However, the over-reliance on chemical weed control has led to shifts in weed communities in agroecosystems which are now becoming dominated by high competitors and herbicide resistance. Thus, weed scientists and practitioners are urged to develop and incorporate innovative and feasible integrated weed management (IWM) systems that can reduce weed infestations and environmental impacts.

Book Synopsis The Ecology of Seeds by : Michael Fenner
Download or read book The Ecology of Seeds written by Michael Fenner and published by Cambridge University Press. This book was released on 2005-02-24 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: What determines the number and size of the seeds produced by a plant? How often should it reproduce them? How often should a plant produce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The authors bring together information on the ecological aspects of seed biology, starting with a consideration of reproductive strategies in seed plants and progressing through the life cycle, covering seed maturation, dispersal, storage in the soil, dormancy, germination, seedling establishment, and regeneration in the field. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.
