Resíduos agrícolas e argila expandida no cultivo da orquídea Oncidium baueri Lindl.

For orchid cultivation in containers is essential to select the right substrate, since this will influence the quality of the final product, it serve as a support for the root system of the plants. This study aimed to evaluate different agricultural residues and expanded clay in Oncidium baueri Lindl. orchid cultivation. The plants were subjected to treatments: pinus husk + carbonized rice husk, pinus husk + coffee husk, pinus husk + fibered coconut, pecan nut husk, expanded clay, fibered coconut, coffee husk, carbonized rice husk, pinus husk. After eleven months of the experiment, the following variables were evaluated: plant height; largest pseudo-bulb diameter; number of buds; shoot fresh dry matter; the longest root length; number of roots; root fresh matter; root dry matter; and electric conductivity; pH and water retention capacity of the substrates. Except the expanded clay, the other substrates showed satisfactory results in one or more traits. Standing out among these substrates pinus husk + coffee husk and pine bark + fibered coconut, which favored the most vegetative and root characteristic of the orchid. The mixture of pinus husk + coffee husk and pinus husk + fibered coconut, provided the best results in vegetative and root growth of the orchid Oncidium baueri and the expanded clay did not show favorable results in the cultivation of this species.

Construção e calibração de um inclinômetro para uso em tratores agrícolas como instrumento de segurança

The tractors are the main potency source, for the traction of tillage equipments and their use are increasing more and more in Brazilian agriculture. In spite of the great technological progress the increase of the number of agricultural tractors brought positive aspects and some negative, among these last ones it stands out the appearance of a new source of work accidents, which importance is given by the physical damages caused to the operator. Therefore the objective of this work was to project and develop an inclinometer, which indicates the inclination of the land, as safety sensor for agricultural tractors to avoid lateral hollovers, through a resonant sign, for the operator and the machine preservation. The built and evaluated inclinometer showed to be efficient for inclination indication of different areas during field operations with agricultural tractors, small angle oscillation and enough answer time to help operators to take decisions in imminence situation of lateral machine hollovers.

Escola técnicas agrícolas: um estudo sobre ensino de Matemática e formação de professores

The central focus of this paper is to establish that the Brazilian Education Programa to prepare professionals in Technical-Agricultural Schools is suffering a kind of marginalization which comes from two distinct perspectives: the intention to prepare professionals (being a branch of Technical Education) and the relationship to the countryside (a community space historically seen as peripheral in its relation to urban culture). The paper discusses – from a historical and sociological point of view and using Oral History as methodological approach – the experiences of Math’s teachers in their daily struggles against some conceptions of other teachers (mainly those of technical areas) and against all the “regular” schooling system.

Treinamento básico sobre operação e segurança operacional de máquinas agrícolas

The study is intended to portray the experiment of mechanical engineering course academicians’ that work on health and labor security field, at the project “Primary Training of Operation and Operational Security of Agricultural Machines”, by practical and theoretical content for workers of a rural community, aiming operational security orientation on their work activities.

Navegação autônoma em ambientes agrícolas utilizando visão estéreo

A visão estéreo é uma forma eficiente para navegação, pois com a estimativa de profundidade, é possível verificar se um caminho pré determinado pode ser utilizado para chegar ao destino definido, e ainda estimar durante qual profundidade esta mesma estimativa continuará sendo válida. As imagens capturadas por cada câmera são retificadas, de forma que as mesmas fiquem alinhadas horizontalmente, colaborando-se assim com o desempenho dos algoritmos de correspondência, responsáveis pela construção da matriz de disparidades. Com base nessa matriz, é criada a matriz de disparidade “V” para que seja possível mapear a informação de profundidade de cada objeto, os quais podem representar obstruções e anteparos na cena observada.

Inovação tecnológica de boas práticas agrícolas e a informática na gestão agropecuária

This study aims to develop innovative proposals for production agriculture management and plans to build a participatory model, through the digital inclusion of members of the family farm gathered in a cooperative venture seeking to establish new environmental management efficiency for household production. The first part of the hypothesis assumes that a major obstacle to the insertion of small family farms into the markets is skilled labor, human capital. A training model has been developed for traceability and tracking activities on family farms, based on the atemoya culture. The second hypothesis predicts that it is possible to create a model that is scientifically supported by widely accepted rules derived from GlobalGAP standard certification, a global benchmark for good agricultural practices. Using these rules the model seeks to achieve the traceability of agricultural products and operations from the preservation of identity information within the production chain. The results obtained by the computerized system confirmed the presented hypotheses by demonstrating that technological innovation through intensive communication and information technologies education as well as other associated forms are important drivers of regional development, especially if implemented through a digital inclusion project using the state program Infocentros Access São Paulo.

Avaliação do desempenho das máquinas agrícolas na implantação da cultura do girassol

The sunflower oleaginous is the fourth of recognized importance in the oil production and few studies related to agricultural operations adopted for this crop. The objective of the present work was to study the performance of agricultural machines in the conventional tillage and reduced in the plantation of the sunflower crop. The experiment was installed at the Experimental Farm of Lageado, belonging to the Faculty of Agricultural Sciences of UNESP, located in Botucatu-SP. It consisted of two types of tillage (conventional tillage-CC and reduced tillage-CR), with experimental design in randomized blocks and four replications. The treatment CC promoted less coverage of the soil surface protected with waste when compared to CR treatment. The chisel plow was the tillage of equipment that required the tractor higher average traction force, average power traction and slippage, consequently, promoted lower average speed of work. The theoretical field capacity and area of land involved in the treatment CR were superior when compared to treatment CC, thereby lower consumption of fuel per hour worked was lower in CR treatment.

Demanda energética de máquinas agrícolas na implantação da cultura do sorgo forrageiro

Forage sorghum can be grown in areas and environmental conditions dry and warm, where the productivity of other forage plants can often be uneconomical. The soil disturbance can be made only on the lines of planting (direct seeding) or entirely from the area for seeding (conventional tillage), as plowing, harrowing, subsoiling and chiseling (minimum tillage). The displacement speed ideal for planting is one in which the groove is opened and closed without removing the over-ground, allowing the distribution of seed spacing and depth constant. The experiment was conducted in a soil classified as Typic Oxisol at Lageado Experimental Farm, Faculty of Agronomic Sciences, UNESP, Botucatu campus. This study aimed to evaluate the response of sorghum in four forward speeds (3, 5, 6 and 9 km h-1) and four systems of soil management: SD (direct seeding), GP (harrow + sowing), LPG (disc harrow and two light disking + sowing) and CR (scarification and seeding). Data was subjected to analysis of variance in a factorial 4 x 4 and a randomized block design with split plots. The following parameters were determined: average speed, average strength of the drawbar, the average power drawbar, theoretical field capacity of the tractor-equipment, fuel consumption per hour. For the conditions under which the experiment was conducted, it was concluded that the hourly fuel consumption was not influenced by tillage systems and was inversely proportional to the increase of speed work, and that the change of speed in the sowing operation did not provide additional the values of average traction force on the bar of the tractor-planter.
