Fertilizantes fosfatados para a cana-de-açúcar aplicados em pré plantio (fosfat...
Sousa, Robson Thiago Xavier dePhosphate application is still rarely used in sugarcane and can be done with phosphorus fertilizers of long residual period. This study evaluated the effect of phosphate fertilizers applied in the whole area before planting on sugarcane yield and technological quality. The study was done at Jalles Machado sugar-mill, in Goianésia-GO, during three growing seasons. The treatments consisted of five different phosp...
Espectroscopia de infravermelho próximo em análises de solos e plantas
Santos, Ana Paula dosFundação de Amparo a Pesquisa do Estado de Minas Gerais; Analyses of soils and plants, essential for crop fertilization management, are based on methodologies that are time and reagent consuming. Near infrared spectroscopy (NIR - Near-infrared) has proven as a faster and cleaner alternative for simultaneous quantification of compounds. This study evaluates the methodologies based on NIR combined with multivaria...
Influência de fungicida e adubação foliar em características agronômicas e sani...
Alvim, Karen Rodrigues de ToledoWhat defines the maximum potential of a culture s production is the set of factors related to: the history of the area, the genetic material, growing practices, climatic conditions, etc. Among these practices, the availability of nutrients and the use of chemicals for protection against pathogens are highlighted. Therefore, the objective of the present work was to verify the influence of foliar nutrition and pr...
Sistemas e épocas de cultivo na produção agronômica e de óleo essencial de Meli...
Silva, Sérgio MacedoFundação de Amparo a Pesquisa do Estado de Minas Gerais; Melissa officinalis is a medicinal and aromatical, species originary from Asia and Europe, adapted to a subtropical and tempered climate, being, however, found in almost all Brazil. To discover which they are the forms to get one high productivity and products with the essential oil concentrations and good quality and amount it is necessary to submit to t...
Tamanho ótimo de amostra para análise da qualidade fisiológica de diásporos de ...
Oliveira, João Paulo Ribeiro deFundação de Amparo a Pesquisa do Estado de Minas Gerais; What are the consequences of working with different sample sizes? What are the consequences of this on quality of results? What is the minimum sample size required for the results of germination measures to be representative of the population? Thinking about this, this study evaluated different sizes of samples to obtain the optimum sample size for germin...
Biologia e comportamento de Sitobion avenae (Hemiptera: Aphididae) em quatro cu...
Silva, Aline MarianoThe use of resistant wheat cultivars to S. avenae is important for the management of culture due to the potential damage of aphid. In Brazil, however, little is known about the resistance of wheat cultivars to S. avenae. The goal of this work was to assess the behaviour and biology of S. avenae in leaves and ears of four commercial wheat cultivars to verify the existence of resistance by antibiosis into leaves ...
Atributos químicos do solo e teor foliar de nutrientes em cana-de-açúcar sob di...
Moraes, Emmerson Rodrigues deFundação de Amparo a Pesquisa do Estado de Minas Gerais; Since its introduction in Brazil, Sugarcane (Saccharum spp) is known for its importance to the country. Actually, its eminence is due to the energetic source with ethanol production, reducing petrol consume and dependence. Regarding the renewable source of clean energy and its different applications it becomes essential its sustainable production, decreas...
Reação de genótipos de soja transgênicos e convencionais a podridão branca da h...
Caires, Anderson MonteiroCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Stem white rot, caused by Sclerotinia sclerotiorum, is increasing in soybean fields, mainly due to the use of seeds infected with the mycelium of the fungus. The control of soybean white mold requires the integration of various measures, including genetic control through the selection of soybean genotypes with partial resistance to the pathogen. The o...
Características físicas e fisiológicas de Aquênios de Lychnophora ericoides Mar...
Lopes, Susana WeberLychnophora ericoides is a shrub like species, endemic to rock outcrops areas, whose cultivation practices are unknown and its irregular maturation being the great problem for seedling production. The objective of the work was to evaluate the germination of L. ericoides cypsela collected from across different altitudes of a population occurring in the Serra da Bocaina, region of Alto Paranaíba, Minas Gerais, an...
Interação entre diferentes níveis populacionais iniciais de Pratylenchus brachy...
Silva, Rafaela BernardesCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Due to the significant damage that Pratylenchus brachyurus causes to soybean, this study evaluated different initial populations of this nematode and soybean and investigated the effect of this interaction in plant development and nematode reproduction under greenhouse conditions. The experiment was conducted in completely randomized design as a 6x8 f...
