This book was released on 1990 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Instalaram-se de 1969 a 1988, nas diferentes regioes triticolas paulistas, 134 experimentos em condicao de sequeiro e 34 experimentos com irrigacao por aspersao, visando estudar as respostas de cultivares de trigo recomendados para cultivo em cinco niveis de adubacao nitrogenada, fosfatada e potassica, empregando o delineamento estatistico central composto, onde os oito primeiros pontos corresponderam a um fatorial 2 3 e os sete seguintes foram pontos axiais incluindo um ponto no centro do delineamento. Em 93 experimentos foram incluidos tres tratamentos extras que permitiram avaliar o efeito do enxofre. Foram tambem instalados 15 ensaios de 1985 a 1988 com irrigacao por aspersao, visando avaliar a resposta de cultivares de trigo a diferentes modos de aplicacao da adubacao nitrogenada. Os resultados obtidos permitiram a elaboracao de uma tabela de recomendacao de adubacao fosfatada e potassica para condicao de sequeiro e com irrigacao em funcao dos teores de fosforo e potassio no solo, extraidos pelo metodo da resina. Em solos com teores de fosforo de 0-6, 7-15, 16-40 e > 40 ug/cm3 recomendou-se a aplicacao no sulco de plantio de 90, 60, 40 e 20 kg/ha de P2O5, respectivamente, e em solos com teores de potassio de 0-0,07; 0,08-0,15; 0,16-0,30 e > 0,30 meq/100 cm3 respectivamente, recomendou-se a aplicacao no sulco de plantio de 40, 30, 20 e 10 kg/ha de K2). Considerando a adubacao nitrogenada, em condicao de sequeiro e com irrigacao, concluiu-se pela aplicacao de 20 kg/ha de nitrogenio no sulco de plantio, porem no caso da cultura do trigo suceder a cultura de soja os dados indicaram nao haver necessidade de aplicacao da adubacao nitrogenada. Em relacao a adubacao nitrogenada em cobertura, recomendou-se: (a) nao aplicacao em cultura de sequeiro e quando se utilizar de cultivares de porte alto, sensiveis ao acamamento em cultura irrigada; (b) aplicar ate 40 kg/ha de N aos 30 dias apos a emergencia, quando forem utilizados cultivares de porte baixo e de ciclo precoce, em condicao de irrigacao; e (c) aplicar 20 kg/ha de N aos 50-60 dias apos a emergencia, quando forem empregados cultivares de porte baixo e ciclo medio ou tardio, em condicao de irrigacao. Recomendou-se a aplicacao de 10 kg/ha de enxofre no sulco de plantio independente da cultura ser de sequeiro ou irrigada.

Book Synopsis Sugarcane Bioethanol by : Luís Augusto Barbosa Cortez
Download or read book Sugarcane Bioethanol written by Luís Augusto Barbosa Cortez and published by . This book was released on 2010 with total page 994 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Brazil, sugarcane ethanol supplied, in 2009, 17.6 % of the energy for land transportation (excluding railroads)and about 55% of the total energy supplied by liquid fuel for Otto cycle engines. Besides the lower production costs ethanol produced from sugarcane in Brazil has another important advantage: in Central-South Brazil only 1 unit of fossil energy is used for each 8-9 units of energy produced by ethanol from sugarcane. Carbon emissions reduction also benefits from sugarcane ethanol: for each cubic meter of ethanol used as fuel, there is net saving of around 2 t CO2 not emitted to the atmosphere while, at the same time, no SO2 is emitted. Sugarcane was introduced in Brazil in 1532. The "Brazilian model" of producing concomitantly sugar and ethanol, brought important technical benefits and made possible an outstanding increase in the competitiveness in the international market for sugar and ethanol. Today about 50% of the sucrose of sugarcane produced in the country is directed to the production of sugar while another half is used to produce Ethanol. Industrial and academic R&D has helped to increase the productivity of ethanol steadily over the past 35 years, at a rate of 3.2% per year. Productivity gains implied savings of planted area by a factor of 2.6. In 2009/2010 the area planted with sugarcane for Ethanol production was 4.2 Mha, amounting to 1% of the total arable land available in Brazil. About 60% of the Ethanol produced in Brazil comes from the State of Sao Paulo, where the productivity is the highest (around 86 t/ha.year). Most of the recent expansion is happening in the center-west region of the country, in degraded pasture lands. The FAPESP Program for Research on Bioenergy, BIOEN, aims at articulating public and private R&D, using academic and industrial laboratories to advance and apply knowledge in fields related to ethanol production in Brazil. The BIOEN Program has a solid core for supporting academic exploratory research activities that will generate new knowledge and form scientists and professionals essential for advancing industry capacity in ethanol related technologies. On top of this, BIOEN includes partnerships with industry for cooperative R&D activities between industrial and academic laboratories, which are to be co-funded by FAPESP and industry.Federal agencies, such as CNPq, will also co-fund the research.

Book Synopsis Osmolytes and Plants Acclimation to Changing Environment: Emerging Omics Technologies by : Noushina Iqbal
Download or read book Osmolytes and Plants Acclimation to Changing Environment: Emerging Omics Technologies written by Noushina Iqbal and published by Springer. This book was released on 2015-12-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continual change in climatic conditions induces a series of adaptations in plants to suit the unfavorable conditions for sustainable agriculture. For sustainable agriculture, it is important to unravel the precise mechanism(s) that disturb the homeostatic equilibrium at cellular and molecular level and also to enhance understanding to build strategies for the tolerance of plants. Osmolytes have long been identified as pivotal abiotic stress busters because of their role in plants in overcoming extremely harsh environmental conditions. This edited compilation attempts to put forth the scattered knowledge on osmolytes and their role in abiotic stress tolerance together and disseminate as a package to deal with the problems of lower productivity under stressful environment. It will enhance the understanding on osmolytes function and bioengineering of plants for abiotic stress tolerance. The book covers very interesting topics dealing with various osmolytes and the mechanistic approach for abiotic stress tolerance to pave the path of agricultural scientists, breeders for developing high yielding sustainable transgenic crops.
