This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A cultura da cana-de-açúcar possui enorme importância no cenário agrícola brasileiro por séculos, tomando o Brasil o maior produtor mundial com esta cultura. A capacidade de aumento na quantidade de cana-de-açúcar produzida no Brasil enfrenta limitações físicas (existência de novas áreas de cultivo) e tecnológicas (aumento da capacidade produtiva por programas de melhoramento, melhoria dos ambientes de cultivo). Estudos de inoculação identificaram uma mistura contendo cinco espécies de bactérias diazotróficas endofiticas como capaz de aumentar significativamente a matéria seca das plantas e incorporar até 33% do nitrogênio contido na planta via FBN, em comparação com valores obtidos de plantas não inoculadas. Neste trabalho, foram estudados parâmetros microbiológicos e agronômicos da associação entre plantas de cana-de-açúcar e bactérias diazotróficas endofiticas. Demonstramos a influência da umidade do solo na sobrevivência de algumas espécies endofiticas na ausência da planta hospedeira, sendo possível detectar células de bactérias endofiticas após 40 dias de inoculação no solo com elevada umidade. Demonstramos a permanência das espécies inoculadas ao longo de dois ciclos produtivos da cana-de-açúcar, em níveis populacionais que variaram de acordo com a época de coleta, desde uns poucos isolados até populações acima 105 células por grama de tecido vegetal. Os efeitos da inoculação de duas misturas de bactérias diazotróficas endofiticas foram avaliados em duas variedades de cana-de-açúcar micropropagadas, sob diferentes condições de manejo, ocorrendo tanto o aumento como a diminuição da produtividade em resposta aos tratamentos de inoculação, conforme as interações entre os parâmetros avaliados. A variedade de cana-de-açúcar SP70-1143 obteve contribuições significativas na produtividade de colmos e na produtividade de sacarose, na ausência de adubação nitrogenada, para as classes Planossolo e LVA (baixa e média fertilidade natura4 respectivamente). Na classe de solo TRE (elevada fertilidade natural), não houveram diferenças significativas entre os tratamentos de inoculação e as plantas controle para a variedade SP70-1143, enquanto para a variedade SP81-3250 notamos uma diminuição não significativa na produtividade de colmos, para as três classes de solo. As maiores contribuições da FBN foram observadas no Planossolo, chegando a 31,3% no primeiro corte da variedade SP70-1143, e 42,7% no segundo corte da variedade SP81-3250. Além disso, a contribuição significativa da FBN esteve associada a aumentos significativos na produtividade apenas para a variedade SP81-3250. Na avaliação da transmissibilidade dos efeitos da inoculação, foram encontradas diferenças significativas na produtividade das parcelas, havendo correspondência entre as parcelas oriundas dos tratamentos de inoculação e as parcelas que receberam fertilizante nitrogenado, além do reisolamento de todas as espécies utilizadas nas inoculações. The sugarcane culture has great importance in Brazilian agribusiness, turning Brazil the largest world producer of this crop. Several species of plant growth promoter microrganisms have being described in association with sugarcane, what turns possible searching for species to use as inoculant. Inoculation studies identified a mixture containing five species of endophytic diazotrophic bacteria able to increase significantly the dry matter content, and to incorporate up to 33% of the total nitrogen contained in the plant through BNF. In this work, we studied microbiological and agronomic parameters of the association between sugarcane plants and endophytic diazotrophic bacteria. We demonstrated the influence of soil moisture in survival of some of the endophytic bacteria, in absence of host plant, and that was possible to detect culturable cells in selective semi-solid media after 40 days of inoculation in the presence of high moisture. We also evaluated permanence ofthe inoculated species along two productive sugarcane cycles, in population levels that varied in time from some few isolates, to populations above 105 cells per gram of plant wheight. In another experiment, we tested two different mixtures of endophytic diazotrophic bacteria, in two micropropagated sugarcane varieties, under different levels of N-fertilizer, in a field trial for two consecutive crops, in three soil classes (Ultisol, Alfisol and Oxisol). We found the increasing as well as the decreasing of productivity, depending on interactions among tested parameters. The sugar-cane variety SP70-1143 obtained significant contributions in stem and sucrose productivity from the biological f1Xation, in absence of nitrogen fertilization, when cultivated in soil classes Oxisol and Ultisol (the lowest and average natural fertility, respectively). In the Alfisol soil class (high natural fertility), there were no significant differences between the inoculation treatments and control p1ants of the SP70-1143 variety; while the SP81-3250 variety presented not significative decreases in productivity of stems in all the soil classes. It was demonstrated that the productivity and FBN were under influence of the plant genotipe, soil class, and nitrogen fertilization level. The 1argest FBN contributions were observed in the lowest fertility soil, reaching up to 31.3% in the first cut for SP70-1143 variety, and 42.7% in the second cut ofSP81- 3250 variety. It was demonstrated that the significant contribution of FBN was not always associated to significant increases in plant productivity. In the evaluation of transmissibility of the inoculation effects, we found significant differences among productivities, having correspondence with productivity of p1ants originated from inoculated treatments, and plants that received nitrogen fertilization, besides reisolation of all the species used in in vitro inoculations.

Book Synopsis Plant-Microbe Interactions in Agro-Ecological Perspectives by : Dhananjaya Pratap Singh
Download or read book Plant-Microbe Interactions in Agro-Ecological Perspectives written by Dhananjaya Pratap Singh and published by Springer. This book was released on 2017-12-15 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book puts an updated account on functional aspects of multiphasic microbial interactions within and between plants and their ecosystem. Multipronged interaction in the soil microbial communities with the plants constitute a relay of mechanisms that make profound changes in plant and its micro-environment in the rhizopshere at physiological, biochemical and molecular levels. In agro-ecological perspectives, such interactions are known to recycle nutrients and regulate signalling molecules, phytohormones and other small molecules that help plant growth and development. Such aspects are described deeply in this book taking examples from various crop plants and microbial systems. Authors described the most advantageous prospects of plant-microbe interaction in terms of inoculation of beneficial microorganisms (microbial inoculants) with the plants in which microbes proliferate in the root rhizosphere system and benefit plants' with definite functions like fixation of nitrogen, solubilization and mobilization of P, K, Zn and production of phytohormones. The subject of this book and the content presented herein has great relevance to the agro-ecological sustainability of crop plants with the help of microbial interactions. The chapters presented focus on defining and assessing the impact of beneficial microbial interactions on different soils, crops and abiotic conditions. This volume entails about exploiting beneficial microbial interactions to help plants under abiotic conditions, microbe-mediated induced systemic tolerance, role of mycorrhizal interactions in improving plant tolerance against stresses, PGPR as nutrient mobilizers, phytostimulants, antagonists and biocontrol agents, plant interactions with Trichoderma and other bioagents for sustainable intensification in agriculture, cyanobacteria as PGPRs, plant microbiome for crop management and phytoremediation and rhizoremediation using microbial communities. The overall content entrust advanced knowledge and applicability of diversified biotechnological, techno-commercial and agro-ecological aspects of microbial interactions and inoculants as inputs, which upon inoculation with crop plants benefit them in multiple ways.

This book was released on 2008-07-22 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.

Download or read book Microbial Interventions in Agriculture and Environment written by Dhananjaya Pratap Singh and published by Springer Nature. This book was released on 2019-11-27 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial communities and their functions play a crucial role in the management of ecological, environmental and agricultural health on the Earth. Microorganisms are the key identified players for plant growth promotion, plant immunization, disease suppression, induced resistance and tolerance against stresses as the indicative parameters of improved crop productivity and sustainable soil health. Beneficial belowground microbial interactions with the rhizosphere help plants mitigate drought and salinity stresses and alleviate water stresses under the unfavorable environmental conditions in the native soils. Microorganisms that are inhabitants of such environmental conditions have potential solutions for them. There are potential microbial communities that can degrade xenobiotic compounds, pesticides and toxic industrial chemicals and help remediate even heavy metals, and thus they find enormous applications in environmental remediation. Microbes have developed intrinsic metabolic capabilities with specific metabolic networks while inhabiting under specific conditions for many generations and, so play a crucial role. The book Microbial Interventions in Agriculture and Environment is an effort to compile and present a great volume of authentic, high-quality, socially-viable, practical and implementable research and technological work on microbial implications.

The covered topics and sub-topics of the microbial domain have high implications for the targeted and wide readership of researchers, students, faculty and scientists working on these areas along with the agri-activists, policymakers, environmentalists, advisors etc. in the Government, industries and non-government level for reference and knowledge generation.
Book Synopsis Plant Analysis Manual by : I. Walinga
Download or read book Plant Analysis Manual written by I. Walinga and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the field of plant analysis there is a confusing variety of methods and procedures, both for digestions and determinations. In many cases the digestion and the subsequent determination are interrelated. For example, a separate digestion is needed for trace elements in order to obtain determinable concentrations. The authors have chosen a design in which the digestion/extraction procedure is described in one chapter together with all determination procedures that may be carried out on that particular digest/extract. All the necessary information (such as standardizations) appears in appendices. As a consequence, several determination procedures are described two or three times, however, each based on a particular digestion or extraction method. Two types of determination procedure are described: manual and automated. Manual procedures are mainly used in research laboratories, whereas automated procedures are more frequently applied in routine laboratories. Both types of determinations can be used freely, provided that appropriate equipment is available. The determination procedures are only for inorganic components, usually elements. Besides, most procedures are designed to give a total content value of the element under consideration, regardless of the chemical structure in which it occurs in the plant. The Plant Analysis Manual is intended for the practicing (agricultural) chemist.

Book Synopsis Nitrogen Fixation in Agriculture, Forestry, Ecology, and the Environment by : Dietrich Werner
Download or read book Nitrogen Fixation in Agriculture, Forestry, Ecology, and the Environment written by Dietrich Werner and published by Springer Science & Business Media. This book was released on 2005-10-24 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.
