A seleção e a otimização de sistemas mecanizados são os principais objetivos da mecanização racional. Não é suficiente uma compra adequada do maquinário agrícola se sua utilização não for controlada em aspectos operacionais e financeiros.... more
Crown rust (Puccinia coronata f. sp. avenae) is the most important disease of oats in Brazil. In susceptible oat cultivars, fungicides are needed to control the disease efficiently. However, spray at low volumes may reduce fungicide... more
A colheita mecanizada é ferramenta fundamental no processo produtivo das grandes culturas; se não for realizada adequadamente, poderá resultar em danos mecânicos severos às sementes, acarretando, prejuízos significativos na colheita,... more
Visando a avaliar a cultura do melão rendilhado em função do manejo da irrigação, foi realizado um experimento em casa de vegetação com a cultivar Bônus nº 2, na área experimental do Departamento de Engenharia Rural da Escola Superior de... more
The present work aimed to evaluate the seeder performance in the direct sowing system. The studied factors were three cover crop managements, chosen according to the size of the vegetation fragment, such as straw (straw totally... more
This work was done with the objective of evaluating a low-pressure irrigation system (bubbler system), under field conditions. This evaluation consisted of a study divided in two phases: in the first, the hydraulic design of the... more
Este trabajo ofrece una síntesis de una investigación doctoral sobre los factores estratégicos que influyen en el desempeño de las Unidades de Producción Rural del Sector Agrícola con vocación comercial (UPRU´s Agrícolas) del Bajío... more
The objective of this research was to characterize the spatial variability of chemical attributes of soils cultivated with sugarcane in areas with variations in relief forms. The two soils studied were a Latosol, placed in a convex... more
A manutenção dos tratores agrícolas pode ser considerada um conjunto de procedimentos que visa a manter o equipamento nas melhores condições de funcionamento, propiciando aumento da vida útil, evitando danos prematuros, eliminando os já... more
The wear resistance of rotary plows operating in a clay loam soil was studied. The degree of damage caused to the soil and the amount of mass lost by the tools were determined in order to establish correlations between the physical... more
The purpose of this article is the evaluation of São Domingos River Basin (SDRB) water quality and tentative correlations with natural and anthropic polluting sources. In order to achieve it, physicochemical parameters were analyzed in 65... more
The reduction of a second growing season of sugarcane can lead to spread soil compaction, due to mechanical harvesting of sugarcane in the rainy season. Thus, it is necessary to define strategies to minimize this process. This study aimed... more
A recuperação da topografia de ovos por meio de análise de imagens digitais permite, de forma não destrutiva, a estimativa das massas da gema, da clara, da casca e totais, que são produtos amplamente utilizados na esfera industrial. O... more
The mechanized harvesting of sugarcane when accomplished in times of crop where the soil meets the inappropriate water contents has been responsible for soil compaction and reduction of yield in subsequent cycles of the crop. This study... more
Remote sensing data are each time more available and can be used to monitor the vegetal development of main agricultural crops, such as the Arabic coffee in Brazil, since that the relationship between spectral and agronomical data be well... more
The quality of seedling is critical to obtain vigorous plants in the field. The present study aimed to assess biomasses and biometric relations of soursop seedlings. We used different substrates in protected environments. The experiment... more
O feijão-caupi é uma cultura de grande relevância socioeconômica nas regiões Norte e Nordeste do Brasil. No entanto, apresenta baixa produtividade. A irrigação é uma técnica que possibilita aumentos na produtividade e na rentabilidade dos... more
Tendo em vista a elevação do custo das sementes miúdas e a inadequação das semeadoras de precisão atuais, que não semeiam culturas com pequenos espaçamentos entre linhas, o presente trabalho teve o objetivo de apresentar os resultados dos... more
Com o objetivo de determinar a dose e a faixa de pH dos coagulantes sulfato de alumínio (SA), sulfato ferroso clorado (SFC), cloreto férrico (CF) e extrato de semente de moringa (ESM), que proporcionassem maior eficiência na remoção da... more
The water absorbent polymer effect on vegetative growth and production of Theoretical Recovery Sugar (TRS) of sugarcane cv. RB 86 7515 was evaluated on two field tests installed in randomized blocks, with four treatments and five... more
Currently, the standards that deal with the determination of the properties of rigidity and strength for structural round timber elements do not take in consideration in their calculations and mathematical models the influence of the... more
The purpose of this work was evaluating the energetic demand of a seeder-fertilizer machine as a function of the type and handling of vegetal covering culture and of the fertilizer deposition shank depth. A Valtra BM100 tractor was used... more
