Available in PDF, EPUB and Kindle. Book excerpt: The increased adoption of conservation tillage in vegetable production requires more information on the role of various cover crops in weed control, tomato quality, and yield. Three conservation-tillage systems utilizing crimson clover, turnip, and cereal rye as winter cover crops were compared to a conventional black polythene mulch system, with or without herbicide, for weed control and tomato yield. All cover crops were flattened with a mechanical roller/crimper prior to chemical desiccation. Herbicide treatments included a PRE application of S-metolachlor (1.87 kg a.i. ha−1) either alone, or followed by an early POST metribuzin (0.56 kg a.i. ha−1) application followed by a late POST application of clethodim (0.28 kg a.i. ha−1). Except for spotted spurge and tall morningglory only the main effect of herbicide treatments and cover crops affected weed control. For the majority of the weeds, no significant differences in weed control were observed with rye residue and plastic mulch treatments; however, turnip and crimson clover residue failed to control most weeds. Rye residue provided 86% large crabgrass, 80% goosegrass and 84% Broadleaf signalgrass control. Yellow nutsedge was controlled 65% by plastic mulch and only 60% by Rye residue. Pokeweed was controlled 80% by plastic mulch treatment. S-metolachlor applied PRE was sufficient in controlling leafy spurge and tall morningglory in plastic mulch and rye residue plots. Yield was less following either crimson clover or turnip cover crops compared to rye or the polythene mulch system. Application of herbicides resulted in better yields compared to the no-herbicide treatments. Economic analysis indicated that there was no significant difference between using a rye cover crop or plastic under any of the alternative herbicide treatment regimes in 2005. This research demonstrates the possibility of growing tomato in conservation tillage systems using high residue cover crops and herbicides to maintain season long weed control.

Available in PDF, EPUB and Kindle. Book excerpt: Nowadays the environmental sustainability of the cropping systems is increasingly requested by the consumers. Conventional tillage practices, totally turning over the soil between the vineyard rows, may cause erosion due to rain as well as structure destruction of the soil in the long term. Conservation tillage is a soil management technique, poorly widespread in Sardinia, allowing cover cropping between vineyard rows. Furthermore, this technique makes the canopy development control of herbage possible by cutting it up during specific phenological phases. Conservation tillage usually involves direct benefits to farmers such as increasing soil fertility as well as reductionof tillage costs, soil erosion and carbon dioxide (CO2) emissions in the atmosphere. This long term trial, during at least five years aims to assess the conservation tillage impact on chemical-physical soil characteristics in comparison with traditional tillage by evaluating the change of organic matter, C.E.C. and availability of major plant nutrients in the soil and to estimate their probable rise. The field plots are located in a 35% slope condition vineyard, showing massive erosion problem and organic matter low content. A split/plot design with four replications was set up, with the comparison between conservation and traditional tillage apart as main plots. Moreover, the effects of two different irrigation levels were evaluated in the subplots of each main plot. At the beginning of the trial (2011) a pedological survey was made. Three soil profiles were described and sampled along the field slope and soil sampling in each plot were made both to characterize the soil and to find the zero point. The soil chemical and physical characteristics were monitored through a second soil sampling made at the end of 2013. Conservation tillage caused increasing organic matter content and C.E.C. values. As for major plant nutrients in soil, results were more uncertain. Grapevine yield and quality parameters did not show any negative effect when passing from conventional to conservation tillage techniques. The trial provided a preliminary positive evaluation of conservation tillage. However, more years are required to confirm this trend.

Price and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased adoption of conservation tillage and organic weed control practices in vegetable production requires more information on the role of various cover crops in integrated weed control, tomato quality, and yield. Two conservation-tillage systems utilizing crimson clover and cereal rye as winter cover crops were compared to a conventional black polythene mulch system, with or without organic weed management options, for weed control, tomato yield, and profitability. All cover crops were terminated with a mechanical roller/crimper prior to planting. Organic weed control treatments included: 1) flaming utilizing a one burner hand torch, 2) PRE application of corn gluten, 3) PRE application of corn gluten followed by flaming, or 4) intermittent hand weeding as needed. A non-treated control and a standard herbicide program were included for comparison. The herbicide program consisting of a PRE application of S-metolachlor (1.87 kg a.i./ha) followed by an early POST metribuzin (0.56 kg a.i. /ha) application followed by a late POST application of clethodim (0.28 kg a.i./ha). In general, high-residue clover and cereal rye cover crops provided substantial suppression of Palmer amaranth, large crabgrass, and yellow nutsedge. Across systems, minimum input in high-residue systems provided the highest net returns above variable costs compared to organic herbicide treatments that are costly and provide marginal benefit.

Available in PDF, EPUB and Kindle. Book excerpt: Adoption of conservation tillage and the use of cover crops for benefits associated with soil health and weed control has increased in recent years. In these systems, the reliance on postemergent (POST) herbicides such as glyphosate has resulted in widespread resistance in weeds. Consequently, residual herbicides must also be used in conjunction with conservation tillage practices and POST herbicides to reduce risk of further resistance evolution. However, residual herbicide applications to crop residue covered soil commonly results in herbicide losses of up to 50% due to interception and adsorption to organic matter (OM). Therefore, greenhouse and field experiments were conducted in 2017 and 2018 in effort to identify application methods and other practices that result in greater efficacy when residual herbicides are applied to crop residue. In the field, efficacy of residual herbicides after application to crop residue-covered soils was enhanced with increasing carrier volumes and most herbicides performed better with XR nozzles compared to TTI nozzles. However, minimum carrier volumes and nozzles required for successful weed control were largely product-specific. In a greenhouse experiment, the addition of a silicone-based adjuvant at an optimal concentration improved acetochlor efficacy after application to wheat straw. Likewise, acetochlor efficacy from application to wheat straw was increased with greater volumes of simulated rainfall. In addition to conservation tillage related experiments, field experiments were conducted in 2017 and 2018 in Mississippi and Nebraska to quantify the relative duration of weed control provided by many commonly used residual herbicides in effort to identify when weed control starts to decline relative to initial application. Lastly, a field experiment was conducted investigating the effects of carrier volume and spray quality in simulated dicamba drift on susceptible soybean experiments. Carrier volume was found to profoundly affect soybean response to dicamba and should be considered in future simulated drift studies.

Available in PDF, EPUB and Kindle. Book excerpt: Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Available in PDF, EPUB and Kindle. Book excerpt: Satisfying consumer needs through the production of healthy and nutritious agricultural products is a substantial challenge facing modern agriculture. However, agricultural production should be carried out with care for plant health, biological safety of products, and environmental safety while minimizing the risks to human health. Therefore, the implementation of agricultural practices while respecting these principles is very important for improving the quantity and quality of crops. Additionally, ecosystems have been altered as a result of human activities and climate change, resulting in the reduction of biodiversity and creation of new niches where pests can thrive. This is of particular importance in 2020, as the United Nations General Assembly declared this year as the International Year of Plant Health (IYPH), with “protecting plants, protecting life” as a leading subject. This Special Issue promotes the subject of plant health and emphasize the importance of preventing the spread of pests, including weeds, which cause substantial economic losses. Research articles cover topics related to the biology and harmfulness of weeds, particularly in connection with crop health, segetal weed communities and their biodiversity, and integrated methods of weed control. For this Special Issue, we welcome all types of articles, including original research, opinions, and reviews.
