Arranjo fisico na montagem com fluxo continuo nas superficies de comando composto

Based on the fierce competitiveness of manufacturing companies and the planning problems arising from the lack of flexibility and forecasting demand, companies are increasingly looking to reflect on the most appropriate methods to manage its manufacture. Today it is possible to obtain higher gains and lower costs through very efficient tools, this paper uses action-research to model and implement the physical layout of a manufacturing cell, with strong theoretical basement returned to Lean Production System and acting systematically in flexibility in mounting. Through observation and joint action of the observer and staff can report problems that occurred during the phases of planning and implementation of improvements. With the improvement of the physical arrangement in the assembly was possible to obtain significant gains by reducing the production cycle, the manpower required, spending of non-compliance and increasing productivity, final product quality and health in the workplace

Rentabilidade na semeadura cruzada da cultura da soja

Soybean cross-seeding tillage came from better spatial arrangement of plants per area, so some producers have opted for this tillage system, which consists in seeding the area in two steps, forming a chessboard with perpendicular lines of tillage. This study aims to analyse the soybean productivity and production costs when it planted in different dispositions of crossed tillage. The experiment was conducted during the harvests 2011/2012 and 2012/2013 at Lageado Farm of the FCA/UNESP, Botucatu-SP, in an area cultivated under no-tillage. The experimental design was in randomized block with five treatments and eight replications. The treatments were: seeding in parallel rows with recommended fertilization and recommended plant population (conventional); cross-seeding with doubled fertilization and doubled plant population; cross-seeding with recommended plant population and doubled fertilization; cross-seeding with doubled plant population and recommended fertilization; cross-seeding with fertilization and recommended plant population. The results showed statistical difference among the treatments, with increased productivity for the cross-seeding with doubled plant population and recommended fertilization. However the conventional tillage with parallel lines shows higher net earnings than soybean cross-seeding, being more profitable for producer.

Soil physical and microbiological attributes cultivated with the common bean under two management systems

Agricultural management systems can alter the physical and biological soil quality, interfering with crop development. The objective of this study was to evaluate the physical and microbiological attributes of a Red Latosol, and its relationship to the biometric parameters of the common bean (Phaseolus vulgaris), irrigated and grown under two management systems (conventional tillage and direct seeding), in Campinas in the state of Sao Paulo, Brazil. The experimental design was of randomised blocks, with a split-plot arrangement for the management system and soil depth, analysed during the 2006/7 and 2007/8 harvest seasons, with 4 replications. The soil physical and microbiological attributes were evaluated at depths of 0.00-0.05, 0.05-0.10, 0.10-0.20 and 0.20-0.40 m. The following were determined for the crop: density, number of pods per plant, number of beans per pod, thousand seed weight, total weight of the shoots and harvest index. Direct seeding resulted in a lower soil physical quality at a depth of 0.00-0.05 m compared to conventional tillage, while the opposite occurred at a depth of 0.05-0.10 m. The direct seeding showed higher soil biological quality, mainly indicated by the microbial biomass nitrogen, basal respiration and metabolic quotient. The biometric parameters in the bean were higher under the direct seeding compared to conventional tillage.
