Domingues, Luis Augusto da SilvaFundação de Amparo a Pesquisa do Estado de Minas Gerais; The growing demand on renewable fuel, despite oil higher prices and pollutant power has promoted an increase on sugarcane s area in Brazil. Its expansion has been occurring preference at savannah s area occupying pasture and crop. In this context, the project was conducted with the purpose of studying different sugarcane environment production under six d...
Manejo intercalar de leguminosas perenes na cultura do café em produção
Cunha, Aquiles Junior daIntercropped legumes in coffee rows perform as green manure, providing good soil coverage and reducing weed infestation. This study evaluated soil coverage and interference of forage peanuts and perennial soybean on weed infestation and phytosociology, and on growth and yield of coffee plants. The experiment was done in Patrocínio/MG, in a 11 years old producing coffee orchard, cultivar Catuaí Vermelho IAC-99, ...
Percloreto de ferro como sinalizador de injúrias em tubérculos de batata e cara...
Silva, Adelaide SiqueiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The use of iron perchlorate as a marker of injury in potato tubers may help preventloss of lots during storage and transport. The objectives of this study were to determine the concentration of iron perchlorate solution and the immersion time for the marking of pectolytic bacteria in potato tubers; the evaluation of potato batches for the presence of ...
Caracterização pedológica de saprolitos de gnaisse e de basalto, e implicações ...
Wangen, Dalcimar Regina BatistaInstituto Federal Goiano; Saprolite may be very thick in regions with humid tropical and subtropical climates. Depending on the degree of fracturing, saprolite can restrict root development and water movement throughout the profile. However, saprolite that has undergone greater alteration can function like soil in terms of drainage, water storage, nutrient supply and physical support for plants. Our objective w...
Potencial do teste de emergência em canteiro para estimar o estabelecimento da ...
Silva, Flávia Andrea NeryHigh physiological quality seed lots indicate that, probably, there will be good performance under several field conditions, and the reference to evaluate this quality is the germination test in the laboratory, which is done under optimal conditions to express all the seed potential. However, laboratory results do not always repeat in the field, where conditions of the seed bed are not ideal to express the same...
Matéria orgânica, fluxo de CO2 e índice Q10 em dois latossolos com texturas con...
Vinhal-Freitas, Isabel CristinaThe different land use systems at Cerrado, with intensive use of land, brought direct consequences in relation to the chemical, physical and biological soil properties. The impacts of land use are rapid degradation and imbalance in the biological processes and nutrient cycling. Soil texture and seasonality can interfere in these processes. The objectives of this study were to determine the changes in the bioche...
Qualidade de sementes de girassol em função da posição no capítulo e da densida...
Oliveira, Carlos Manoel deThe increasing demand for sunflower seed aiming at making edible oil and biofuel is reflected on the seed market since the requirement for quality seeds has become bigger and bigger in recent years. This work aimed to evaluate the quality of sunflower seeds according to the position their in the chapter, to the seedling density, and to the seed weight by means of an experiment at the seed research laboratory of...
Diversidade fenotípica e molecular, correlações entre caracteres, adaptabilidad...
Sousa, Larissa Barbosa deThis study aimed to: a) assess the genetic diversity of soybean genotypes using agronomic traits and microsatellite markers b) assess the phenotypic and genotypic correlations between agronomic traits of soybean lines derived from different crosses, c) study interaction between genotype and environment and evaluate its effect on grain yield and d) evaluate the adaptability and stability of early and late soybea...
Sistema rodoviário de transporte na qualidade fisiológica de sementes de milho
Bertan, Franciéle OlivoFundação de Amparo a Pesquisa do Estado de Minas Gerais; Demand for hybrid maize seed quality is increasing every year, and to meet it seed companies are adopting specific techniques in all phases of production from production fields to seed sowing fields. Among them, especial attention should be paid to forms of transporting seeds, since the effect of temperature and humidity in transportation over long distan...
Fertilizante organomineral para a produção de cana-de-açúcar
Sousa, Robson Thiago Xavier deFertilization of sugar cane plays an utmost important role in its entire production process directly influencing the productivity of the crop. The use of organomineral fertilizers as a source of nutrients may be an alternative to replace mineral fertilizers in this crop. The aim of this study was to verify the efficacy of the use of organomineral fertilizer on sugar cane. From 2011 to 2013 ten experiments were ...
