This book was released on 1981 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Field and greenhouse studies were conducted in two years to evaluate the effects of several pre-plant incorporated and pstemergent herbicides applied alone and in sequence upon growth parameters of soybeans [Glycine max (L.) Merr. Amsoy 71]. In general, the greenhouse and field data supported each other. All PPI treatments oversprayed with the post-emergent 2,4-DB reduced yield when compared with the PPI's alone. All yield reductions were additive effects, except bifenox at 1.12 kg/ha plus 2,4-DB and vernolate at 3.36 kg/ha plus 2,4-DB. A significant reduction in pods dry weight at thirty-eight days after planting did not correlate with the yields (ninety-eight days later), although all significant yield reductions were precede by significant reductions in pods dry weight. Bifenox at 0.56 kg/ha over sprayed with acifluorfen at 0.56 kg/ha increased leaf area, leaf dry weight, support tissue dry weight, and yield (antagonistic effects). Of the postemergent treatments, bentazon gave the least interaction showing only significant decrease in leaf area and support tissue dry weight with the PPI treatments of vernolate at 3.36 and 5.04 kg/ha; at 5.04 kg/ha it also significantly decreased pods dry weight. After bentazon, came acifluorfen followed by dinoseb + naptalam with no significant yield reduction. Dinoseb + naptalan significantly reduced several parameters including pods dry weight ald leaf area when applied over all PPI treatments at the two highest rates. Aciflourfen on the other hand only significantly reduced the growth parameters, other than leaf area, when applied over vernolate at 3.36 and 5.04 kg/ha. The greenhouse results indicated that 2,4-DB applied at 1-trifoliate stage of soybeans reduced several growth parameters when compared with 2,4-DB applied ten days later (3-trifoliate). Vernolate at 3.36 and 5.04 kg/ha reduced chloroform soluble extraction of the soybean laves, under field and greenhouse conditions.

Book excerpt: Plants are important for a permanent ecosystem, because in the ecological pyramid plants support all the other living organisms at the base. Very important organization is thought to be the integral process of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants. Accordingly, it is important to obtain more information about the knowledge concerning yield, biomass, and productivity in plants. Soybean is one of the main crops largely contributing to our life, which is thought to be connected to our ecosystem through the above-mentioned integral process. This book focuses on the soybean, and reviews and research concerning the yield, biomass, and productivity of soybean are presented herein. This text updates the book published in 2017. Although there are many difficulties, the main aim of this book is to present a basis for the above-mentioned integral processes of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants (soybean), and to understand what supports this basis and the integral process. It is hoped that this and the preceding book will be essential reads.

Book excerpt: Developments in the understanding of herbicide activity and toxicology have expanded tremendously in the past fifteen years. Research on the mechanism of action of most major classes of herbicide chemistry has provided scientists with excellent insight into enzyme targets. More recently, developments in molecular biology have provided information about herbicide action at the genetic level. Less well understood are the toxicological aspects of herbicide activity that culminate in plant injury or death. Toxicology, Biochemistry and Molecular Biology of Herbicide Activity is a review of the recent literature on most of the major classes of herbicide chemistry in commercial use. The chapters include information about different aspects of herbicide activity related to photosynthesis, inhibition of amino acid biosynthesis, disruption of cell division and microtubule assembly, activity of phytohormone (auxin) mimics, inhibition of fatty acid biosynthesis and some developments in the understanding of herbicide resistance.

This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Available in PDF, EPUB and Kindle. Book excerpt: It is important that scientists think about and know their history - where they came from, what they have accomplished, and how these may affect the future. Weed scientists, similar to scientists in many technological disciplines, have not sought historical reflection. The technological world asks for results and for progress. Achievement is important not, in general, the road that leads to achievement. What was new yesterday is routine today, and what is described as revolutionary today may be considered antiquated tomorrow. Weed science has been strongly influenced by technology developed by supporting industries, subsequently employed in research and, ultimately, used by farmers and crop growers. The science has focused on results and progress. Scientists have been--and the majority remain--problem solvers whose solutions have evolved as rapidly as have the new weed problems needing solutions. In a more formal sense, weed scientists have been adherents of the instrumental ideology of modern science. That is an analysis of their work, and their orientation reveals the strong emphasis on practical, useful knowledge; on know how. The opposite, and frequently complementary orientation, that has been missing from weed science is an emphasis on contemplative knowledge; that is, knowing why. This book expands on and analyzes how these orientations have affected weed science’s development. The first analytical history of weed science to be written Compares the development of weed science, entomology and plant pathology Identifies the primary founders of weed science and describes their role
