Book Synopsis Efeito de doses de nitrogênio e le lâminas de água sobre as características agronômicas e industriais em duas cultivares trigo (Triticum aestivum L.). by : J. Soares Sobrinho
Download or read book Efeito de doses de nitrogênio e le lâminas de água sobre as características agronômicas e industriais em duas cultivares trigo (Triticum aestivum L.). written by J. Soares Sobrinho and published by . This book was released on 1999 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Com o objetivo de avaliar os efeitos de diferentes quantidades de nitrogenio e agua sobre o comportamento agronomico e industrial de trigo, utilizaram-se quatro doses de nitrogenio (0, 40, 80 e 120 kg/ha), duas cultivares de trigo (BR 18-terena, de qualidade superior e a BR 36-Ianomai, de qualidade intermediaria) e tres laminas d'agua (276, 361 e 458 mm). O nitrogenio, na forma de ureia, foi aplicado 1/3 na semeadura e o restante no perfilhamento. O manejo da irrigacao baseou-se na evaporacao do tanque classe A, determinando-a a cada 30 mm de lamina evaporada. O delineamento foi o de blocos ao acaso em parcelas subdivididas, em quatro repeticoes, sendo as doses colocadas na parcela, as cultivares na subparcela e as laminas na subparcela. A semeadura foi realizada em 15 de junho de 1996, em subparcelas de 15 linhas de 5,0 m de comprimento, espacadas de 0,20 m entre si. As quantidade de agua foram aplicadas atraves do sistema "line source" que produz uma irrigacao diferencial decrscente do centro para as extremidades. As caracteristicas foram divididas em dois grupos: 1-as de natureza agronomica (altura da planta, comprimento da espiga, massa de mil graos, numero de espiguetas ferteis por espiga, numero de espigas por m2, numero de graos por espiga, numero de graos por m2 e rendimento de graos; 2;as de natureza indutsrial (peso do hectolitro, capacidade de extracao de farinha, teor de proteina no graos, microssedimentacao, alveografia e numero de queda. Dentre os componentes do rendimento de graos, o numero de espiguetas por espiga, o numero de graos por espiga, o numero de espigas por m2 e o numero de graos por m2, foram os mais sensiveis as quantidades de agua e de nitrogenio fornecidas. O rendimento de graos foi mais dependente da quantidade de agua do que da quantidade de nitrogenio, e as respostas variaram com as cultivares utilizadas. A cultivar BR 36-Ianomami respondeu com aumento de 55,09 kg de graos a cada 20 kg/ha de N aplicados, quando a lamina d'agua passou de 276 para 361 mm e de 63,31 kg de graos/20 kg de N, quando a lamina passou de 361 para 458mm. A cultivar BR 18-Terena apresentou melhor comportamento, com aumento medio de 67,2 kg de graos para cada 20 kg/ha de N, quando a quantidade de agua passou de 276 e de 76,7 kg/ha de graos/20 kg/ha de N, quando a quantidade de agua variou de 361 a 458. As carateristicas fisico-quimicas e reologicas mais influenciadas positivamente pela adubacao nitrogenada foram o teor proteico e a forca de gluten. A variacao na quantidade de agua exerceu influencia nas caracteristicas determinantes da qualidade industrial, com excecao entre tenacidade e extensibilidade (P/L), indicando, portanto, ser a agua mais importante do que o nitrogenio na producao de materia-prima para panificacao. As menores quantidades de agua alteraram as carecteristicas avalidas no sentido da melhoria da qualidade de panificacao. Apesar das alteracoes verificadas nos valores determinantes das caracteristcas fisico-quimicas e reologicas, com a variacao na quantidade de agua fornecida, elas nao foram suficientes para alterar a classificacao comercial das cultivares utilizadas, indicando ser possivel explorar ao maximo o rendimento de graos, sem prejuizo da qualidade de panificacao. Desta forma, o uso de 120 kg/ha de N e 458 mm de agua promoveram os maiores rendimentos de graos, sem prejuizo da classificacao comercial das cultivares utilizadas.

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.

Book Synopsis Nitrogen Metabolism of Plants by : Konrad Mengel
Download or read book Nitrogen Metabolism of Plants written by Konrad Mengel and published by . This book was released on 1992 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all the advances in agriculture, it is the use of nitrogen fertilizers that has provided the greatest increase in crop yield. The study of nitrogen metabolism is thus of vital importance. Additionally, because nitrogen is a constituent of such a wide range of plant metabolites, the study of their chemistry and biochemistry engages the attention of many plant scientists. This book covers recent developments in this field. Topics include the study of root nodules; the uptake, assimilation, and transport of ammonium and nitrate; amino acid metabolism; the distribution and synthesis of seed proteins; and recent research on polyamines, cyanogenic glycosides, and alkaloids. There are also chapters on denitrification and the impact of nitrogen on agricultural productivity and the environment. With contributions from international experts, this volume will interest all plant physiologists and phytochemists as well as biochemists interested in the behavior of nitrogen compounds.
