This book was released on 2014 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soybean (Gycine max [L.] Merr.) is the most popular oil seed crop in the United States and is the most widely planted row crop in the state of Missouri. The majority of soybean oil is used to produce processed food for human consumption. The fatty acid composition of the oil has important implications for human health, and hence has been a topic of considerable research. In 1982, D.O. Wilson provided evidence that soybean seed protein, oil and fatty acid makeup are related with leaf tissue manganese (Mn) concentration. The overall objectives of this thesis was to determine if that relationship is true in new elite soybean cultivars, and to determine if glyphosate herbicide application and acetyl-CoA carboxylase activity influence soybean seed composition. Through four experiments I determined that foliar application of Mn increased whole-plant tissue Mn, leaf tissue Mn and seed tissue Mn concentrations. Manganese concentration within soybean did relate to seed fatty acid content of soybean seed. Supplemental Mn applied with or without post-emergent herbicides did not influence seed quality beyond the effects of other environmental factors. Application of glyphosate herbicide did not influence tissue Mn concentration or seed composition.

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.

Download or read book Micronutrient Deficiencies in Global Crop Production written by Brian J. Alloway and published by Springer Science & Business Media. This book was released on 2008-02-01 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: A deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. The causes, effects and alleviation of micronutrient deficiencies in crops in: Australia, India, China, Turkey, the Near East, Africa, Europe, South America and the United States of America, are covered, and these are representative of most of the different conditions under which crops are grown anywhere in the world. Links between low contents of iodine, iron and zinc (human micronutrients) in staple grains and the incidence of human health problems are discussed, together with the ways in which the micronutrient content of food crops can be increased and their bioavailability to humans improved. Detailed treatment of topics, such as: soil types associated with deficiencies, soil testing and plant analysis, field experiments, innovative treatments, micronutrients in the subsoil, nutrient interactions, effects of changing cropping systems, micronutrient budgets and hidden deficiencies in various chapters provides depth to the broad coverage of the book. This book provides a valuable guide to the requirements of crops for plant micronutrients and the causes, occurrence and treatment of deficiencies. It is essential reading for many agronomy, plant nutrition and agricultural extension professionals.
Download or read book Physiological and Nutritional Studies of Oilseed Crops in Response to Competition and Manganese Supply written by Katherine Millar and published by . This book was released on 2008 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: My dissertation research focused on the physiological impacts of interspecific competition on seed protein and oil composition and its implication for consumer and industrial use. A two-year field study was conducted at the Agronomy Research Center at Southern Illinois University, Carbondale to investigate the response of five cultivars to three weed competition levels in terms of seed yield, quality, and reproductive development. Greater competition intensity resulted in decreased pod production, pod abortion, seed produced per plant, and total yield. In general, a significant increase in seed protein was evident with increasing competition levels whereas seed oil decreased with competition. By altering the relative proportion of protein and oil, the selling potential of the seed is changed. Physiological and biochemical markers were used to evaluate the intensity of competition at pre-flowering (V7), flowering (R2), and post-flowering (R6). The markers included: trigonelline (TRG, an osmoprotectant), Fv/Fm (chlorophyll a fluorescence), relative water content (RWC), and foliar micronutrients (Mn, Fe, Cu, Zn). The parameters not affected by competition included Fv/Fm and RWC, but they did differ by stage of development. The foliar micronutrients and TRG, however, were most responsive to competition. Furthermore, competition altered the relative proportions of foliar micronutrients and it is suggested that this was through a combination of resource competition and allelopathy. The foliar micronutrients and their proportions may affect seed quality. A greenhouse experiment was conducted using differing levels of Mn supply. This experiment did not work as many of the plants died from several factors such as insect infestation and low lighting. Of the plants that did survive, more Mn was found in the roots of canola and the shoots of soybean. To investigate resource competition for Mn, a growth chamber experiment was conducted that examined the effect of competition level, competitor species, and Mn supply on soybean resource allocation. Under low competition, biomass allocation to roots increased but was not affected by competitor species or Mn supply. Micronutrient partitioning between root and shoot in response to high competition level was significantly different for Mn, but also for Zn, Fe, and Cu. Competitor species impacted root Fe levels. The results suggest that resource partitioning (in terms of biomass and micronutrients) in response to competition for micronutrients is similar to that for competition for macronutrients. More biomass and micronutrients are allocated to tissues used to capture the limiting resource as stress increases. A field study was conducted to determine whether the soil micronutrient pools were altered when competitors were grown with soybean. In general, there were no interactions between competition level and soil type for R2 and seed quality parameters. Competition did not alter soil micronutrient levels but did impact foliar micronutrient concentrations at R2 and seed quality. The effect of soil type also impacted the selected parameters, which may also be related to environmental factors since selected plots were at different geographic locations. The results from this study further support the observation that competition leads to increased protein in seed as seen in Chapter 3.

This book was released on 1977 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greenhouse studies were conducted using soil and solution cultures to: (i) determine the detrimetal effects of manganese on growth and grain yield of soybeans; (ii) determine the variation of manganese in soybean leaves; (iii) determine the critical levels of manganese in the plant; (iv) measure the effect of flooding and of silicon on growth and manganese concentrations in Hill soybeans; and (v) evaluate the differential response of three soybean cultivars to manganese levels. Hill soybeans were grown with six levels of applied manganese ranging from 0 to 80 ppm. Reduction in vegetative growth was observed when the manganese concentration in the youngest fully mature leaf exceeded around 200 ppm. Seed yields appeared to be less sensitive to high levels of manganese than top growth. Manganese concentrations decreased from bottom to of the plant, and for a given trifoliolate, manganese decreased with time. Hill soybeans were flooded for on week and manganese in the leaves immediately doubled, decreasing the plant growth. Seven weeks after draining, trifoliolates that developed immediately after flooding were still high in manganese while the manganese concentration in the youngest trifoliolates was similar to that found in the leaves of the unflooded plants. This reflects the immobility of manganese in the plant. The addition of silicon improved slightly the appearance of Hill soybeans at toxic levels of manganese, but failed to improve growth. Susceptibility of soybean cultivars to both manganese deficiency ...

Available in PDF, EPUB and Kindle. Book excerpt: The application of micronutrients to increase yields has become more popular with increased commodity prices and higher yielding crops. Two studies were completed evaluating secondary and micronutrient for soybean (Glycine max [L.] Merr.) and wheat (Triticum aestivum). The objective of the first study was to evaluate the response of soybean, under a double crop system after wheat, to soil-and foliar-applied macro and micronutrients. Macronutrients (N, P, K) were applied at 22 kg ha−1, micronutrients (Fe, Mn, Zn) were soil applied at 11 kg ha−1 and S was applied at 22 kg ha−1. Plant response parameters were evaluated including changes in nutrient concentration, and seed yield response. Tissue samples were collected at the respective R1 growth stage. Samples were analyzed for the nutrients applied with the fertilizer treatments. Soybean seed yield slightly responded to soil-applied S, Mn, and Zn. When micronutrients were foliar-applied, seed yield was significantly decreased. The second study evaluated the application of S and micronutrients to winter wheat. The objectives were to evaluate the wheat response to sulfur and micronutrient fertilization and evaluate soil testing and tissue analysis as diagnostic tools. Fertilizer treatments consisted of sulfur, iron, manganese, zinc, boron, copper. All of the micronutrients were sulfate-based products and the sulfur treatments were applied as gypsum. Fertilizer treatments were applied as topdress in early spring. Soil samples were collected before fertilizer application and after harvest. Flag leaf samples were collected and analyzed for the nutrients applied with the fertilizer treatments. Significant increases in tissue concentration were observed when Zn, B, and S were applied. Significant increases in soil test Zn, Cu, B, and S were observed compared to the control treatment. Despite the increases in soil test concentration across locations, no significant increases in yield by any of the nutrients or combination of nutrients were observed.

Download or read book Manganese in Soils and Plants written by R.D. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixty years ago at the Waite Agricultural Research Institute, G. Samuel, a plant pathologist, and C. S. Piper, a chemist, published their conclusion that the cause of roadside take-all, a disease of oats, was manganese deficiency. This report, together with the concurrent and independent studies of W. M. Carne in Western Australia were the first records of manganese deficiency in Australia and came only six years after McHargue's paper which is generally accepted as the final proof of the essentiality of this element. There must have been a few doubts for some people at the time, however, as the CAB publication, 'The Minor Elements of the Soil' (1940) expressed the view that further evidence to this effect was provided by Samuel and Piper. Their historic contributions are recognised by the International Symposium on Manganese in Soils and Plants as it meets on the site of their early labours to celebrate the 60th anniversary. This year Australians also acknowledge 200 years of European settlement in this country and so the Symposium is both a Bicentennial and a diamond jubilee event which recognises the impact of trace elements on agricultural development in Australia. In a broader sense, a symposium such as this celebrates, as it reviews, the efforts of all who over the ages have contributed to our knowledge of manganese in soils and plants.
