Book Synopsis The Effect of Preplant Nitrogen Fertilization and Soil Temperature on Biological Nitrogen Fixation and Yield of Alfalfa (Medicago Sativa L.) by : Philip E. Shuler
Download or read book The Effect of Preplant Nitrogen Fertilization and Soil Temperature on Biological Nitrogen Fixation and Yield of Alfalfa (Medicago Sativa L.) written by Philip E. Shuler and published by . This book was released on 1991 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The usefulness of preplant nitrogen (N) in establishing alfalfa in colder production areas has not been well characterized. This study was conducted to determine the effect of preplant N and soil temperature on yield, percent N derived from biological nitrogen fixation (PBNF), and shoot N concentration in alfalfa (Medicago sativa L. cv. 'Vernema'. Field experiments were conducted in 1987 and 1988 at Powell Butte, OR, to determine the effect of five levels of preplant N (0, 10, 20, 40, 60 kg ha−1) on yield and shoot N concentration of alfalfa. Growth chamber experiments were conducted from 1989 through 1991 to examine the effect of five levels of preplant N (0, 10, 20, 40, 80 kg ha−1) and three day/ - night soil temperatures (18/12°C, 24/16°C, 27/21°C) on yield, PBNF, and shoot N concentration of alfalfa. In field experiments, preplant N had no effect on shoot N concentration in either year. In 1987 there was no effect of preplant N on dry matter yield. Application of 20-40 kg N ha−1 preplant N increased dry matter yield in 1988. In growth chamber experiments, the highest rate of dry matter accumulation occurred at a soil temperature of 24/16°C. At 18/12°C and 24/16°C, 40 kg ha−1 preplant N resulted in increased shoot and root dry matter yield. At 18/12°C, 80 kg ha-1 preplant N increased PBNF 14% relative to the zero N control. There was no effect of preplant N on PBNF in plants grown at 24/16°C and 27/- 21°C. The rates of shoot N accumulation were similar at 18/12°C and 24/16°C, and were higher than at 27/21°C. Shoot N concentration was not affected by preplant N treatments. The use of 20-40 kg ha−1 preplant N may result in increased yield without decreasing PBNF when: 1) soil temperature remains below 15°C for at least two weeks after planting, and 2) soil nitrate level is less than 16 mg kg−1. Proper assessment of the use of preplant N in alfalfa establishment requires a careful consideration of both soil temperature and soil N availability.

Book Synopsis Microbes for Legume Improvement by : Almas Zaidi
Download or read book Microbes for Legume Improvement written by Almas Zaidi and published by Springer. This book was released on 2017-10-09 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents in-depth insights into strategies involving plant growth-promoting rhizobacteria (PGPR), including symbiotic/asymbiotic nitrogen fixers and associative/endophyte bacteria, phosphate-solubilizing microbes, as well as arbuscular mycorrhizal fungi and their active biomolecules in legume production. It also examines the latest research findings on the taxonomic status of rhizobia and signal molecules affecting rhizobia-legume symbiosis to improve readers’ understanding of the cultivation of legumes in conventional and derelict soil. The agronomically important microflora broadly discussed have offered solutions to some of the problems associated with expensive fertilizers used in many production systems. This second edition provides an overview of metal toxicity to legumes and presents strategies for the abatement of metal toxicity to legumes. Aimed at professionals, practitioners, researchers and graduate students in microbiology, crop sciences, soil microbiology, biotechnology and environmental microbiology, the book focuses on the basic concepts and practical aspects of useful soil microbiota in legume production.
Book Synopsis Crops as Enhancers of Nutrient Use by : R Duncan
Download or read book Crops as Enhancers of Nutrient Use written by R Duncan and published by Academic Press. This book was released on 2012-12-02 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crops as Enhancers of Nutrient Use examines the various plant and soil factors that contribute to nutrient use efficiency of plants. It attempts to address policies regarding Low Input Sustainable Agriculture (LISA), conservation-oriented cropping systems, and reductions in environmental contaminants. It also presents longer-term remedies to some of the inherent problems of high volume applications of expensive fertilizer nutrients. This book emphasizes plant-soil interaction, particularly, nutritional interactions involving rhizosphere, microbes, and stress on the root system. Stress factors include moisture and low and high pH. The book also covers the genetic and physiological response of plant to nutrients at the cellular level, on a whole-plant basis, and when subjected to stress. This book will contribute to the development of a more cost-effective and judicious nutrient usage of major crops.

Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen fertilization of seedling legumes is a controversial practice intended to provide N to the plant during periods when seed N, soil N, and N2 fixation may not meet plant requirements; eg. prenodulation, postharvest, or in the event of an inoculation failure. Field experiments were conducted in 3 consecutive years (1980, 1981, and 1982) on a Woodburn silt loam soil (Aquultic Argixeroll) containing low soil N to evaluate the effect of 9 rates of NH4 NO3 -N (0-224 kg N ha−1) on nodulation, acetylene reduction (AR), percentage herbage N, percentage nitrate N, and dry matter yield of seedling alfalfa (Medicago sativa L. cv. 'Apollo'). The R. meliloti at the field site were found to be ineffective at N2 fixation, thus an inoculation treatment was added in 1982 by the use of a split-block design. The response of the variables to applied N was evaluated at 10 weeks, and over a postharvest time course. At ten weeks after planting, only the uninoculated, ineffectively nodulated plants exhibited increased herbage yield and %N in response to the applied N. All rates of N fertilization decreased nodulation and AR in a curvilinear response, regardless of rhizobial effectiveness. The applied NH4NO3 continued to decrease AR and nodulation of seedlings through the third week after the initial harvest. Acetylene reduction activity of control plants dropped to 68% of preharvest levels at 2 to 4 days postharvest, then recovered during the next 4 weeks. Herbage nitrate N was increased in one year out of three. Dry matter yield and total herbage N of uninoculated plants were increased during the initial growing season, and unaffected the following spring. Since the inoculated plants showed little response to the N rates, except for decreased N2 fixation, it was concluded that during establishment, managerial emphasis should be placed on inoculation rather than N fertilization to obtain a consistent source of N for herbage protein. An ancillary investigation was conducted to characterize native Rhizobium taken from uninoculated, ineffectively nodulated, M. sativa nodules. Results suggested that Phaseolus vulgaris L. may be an alternate host for the native Rhizobium. Agricultural implications of this finding were discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Fully covers the biology, biochemistry, genetics, and genomics of Medicago truncatula Model plant species are valuable not only because they lead to discoveries in basic biology, but also because they provide resources that facilitate translational biology to improve crops of economic importance. Plant scientists are drawn to models because of their ease of manipulation, simple genome organization, rapid life cycles, and the availability of multiple genetic and genomic tools. This reference provides comprehensive coverage of the Model Legume Medicago truncatula. It features review chapters as well as research chapters describing experiments carried out by the authors with clear materials and methods.
