Book Description
Early planting soybean (Glycine max L.) strategies across the mid-southern United States has complicated weed management in the form of post-harvest weed control. Research has investigated the use of cover crops to aid in management of weed populations during winter months, but conventional cover crops provides minimal weed management benefit immediately following cash crop harvest. Inter-seeding cover crop into crop canopies has potential to promote earlier cover crop establishment, thus creating higher potential for post-harvest weed management. However, factors such as inter-seeding timing, herbicide residue, as well as harvest aid applications must be considered. Therefore, studies were conducted in Mississippi in 2017, 2018, and 2019 to determine if cover crops inter-seeded through soybean could improve weed control used in conjunction with common management strategies in Mississippi production systems. Conclusions drawn from these studies indicate inter-seeded cover crops can be utilized in soybean production systems to improve weed management after harvest.

Book Description
Herbicide-resistant Palmer amaranth is the most troublesome weed in Arkansas row crops, causing producers to rely heavily on multiple mechanisms of action to reduce selection pressure for further evolution of herbicide resistance and to successfully produce a profitable crop. It is critical for the sustainability of weed management not only to adequately control this weed but also to reduce the soil seedbank using both non-chemical and chemical practices. Studies were conducted to determine the effect of soybean row spacing, seeding rate, and herbicide program on Palmer amaranth emergence, survival, and seed production in soybean, the effect of drill-seeded soybean population on Palmer amaranth emergence with and without a residual preemergence (PRE)-applied herbicide, and the impact of integrating cover crops and deep tillage with herbicide programs for glyphosate-resistant Palmer amaranth control in glyphosate- and glufosinate-resistant soybean. Herbicide application timing and choice of herbicide had more of an impact on Palmer amaranth control than either row spacing or seeding rate and greater control was observed in PRE plus postemergence (POST)-applied residual programs compared to POST-only residual programs, regardless of seeding rate and row spacing. Narrow-row soybean reached 95% canopy formation quicker than plants in wide rows, in turn resulting in greater suppression of Palmer amaranth emergence. In drill-seeded soybean, a PRE-applied residual herbicide was more beneficial in reducing Palmer amaranth emergence than increasing soybean density. Using a combination of cover crop and deep tillage along with the addition of a PRE followed by POST-applied residual herbicide program, Palmer amaranth was effectively controlled throughout the season with limited weed seed return to the soil seedbank in both glufosinate- and glyphosate-resistant soybean. Overall, herbicide programs were the strongest factor influencing Palmer amaranth control; however, the addition of a cover crop, deep tillage, and narrow row spacing play a vital role in reducing selection pressure on herbicides, thus reducing risks for new cases of herbicide resistance.

Book Description
Research was conducted from the fall of 2016 to the fall of 2018 to characterize and manage PPO- and glyphosate-resistant Palmer amaranth (Amaranthus palmeri S. Wats). Studies included a multi-county survey to determine the prevalence of PPO-resistant Palmer amaranth biotypes and the PPX2 mutations that confer PPO resistance, an in-field evaluation of control of PPO-resistant and PPO-susceptible Palmer amaranth populations with herbicide treatments applied at either sunrise or midday, and field studies that evaluated cover crop termination for control of Palmer amaranth in Roundup Ready Xtend® and Liberty Link® soybean systems [(Glycine max (L.) Merr.]. Results from this research indicate that PPO-resistant Palmer amaranth infests roughly 80% of west Tennessee fields, at least two herbicides with different, effective sites of action should be applied timely for POST herbicidal control of PPO-resistant Palmer amaranth, and that delaying cover crop termination in both Roundup Ready Xtend® and Liberty Link® soybeans can effectively reduce in-season POST applications and maximize Palmer amaranth control if the correct residual herbicide is included at planting timing.

Book Description
Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Book Description
Permaculture is more than just the latest buzzword; it offers positive solutions for many of the environmental and social challenges confronting us. And nowhere are those remedies more needed and desired than in our cities. The Permaculture City provides a new way of thinking about urban living, with practical examples for creating abundant food, energy security, close-knit communities, local and meaningful livelihoods, and sustainable policies in our cities and towns. The same nature-based approach that works so beautifully for growing food—connecting the pieces of the landscape together in harmonious ways—applies perfectly to many of our other needs. Toby Hemenway, one of the leading practitioners and teachers of permaculture design, illuminates a new way forward through examples of edge-pushing innovations, along with a deeply holistic conceptual framework for our cities, towns, and suburbs. The Permaculture City begins in the garden but takes what we have learned there and applies it to a much broader range of human experience; we’re not just gardening plants but people, neighborhoods, and even cultures. Hemenway lays out how permaculture design can help towndwellers solve the challenges of meeting our needs for food, water, shelter, energy, community, and livelihood in sustainable, resilient ways. Readers will find new information on designing the urban home garden and strategies for gardening in community, rethinking our water and energy systems, learning the difference between a “job” and a “livelihood,” and the importance of placemaking and an empowered community. This important book documents the rise of a new sophistication, depth, and diversity in the approaches and thinking of permaculture designers and practitioners. Understanding nature can do more than improve how we grow, make, or consume things; it can also teach us how to cooperate, make decisions, and arrive at good solutions.

Book Description
FAO’s best-selling 2011 publication, Save and Grow, proposed a new paradigm of agriculture, one that is both highly productive and environmentally sustainable. This new book looks at the application of “Save and Grow” practices and technologies to production of the world’s key food security crops – maize, rice and wheat. With examples drawn from developing countries worldwide, it shows how eco-friendly farming systems are helping smallholder producers to boost cereal yields, improve their incomes and livelihoods, conserve natural resources, reduce negative impacts on the environment, and build resilience to climate change. The book will be a valuable reference for policymakers and development practitioners guiding the transition to sustainable food and agriculture.
