1. ACHPA: A sensor based system for automatic environmental control in hydroponics
Abstract The trend towards tunnel farming and hydroponic systems is increasing owing to the climatic changes as well as the need to increase crop yield. Hydroponic is a technique of growing plants without soil. Tunnel farming and hydroponic system requires controlled environmental parameters like temperature, humidity and soil moisture for better production

2. SEED METERING MECHANISMS AND TRACTOR-SEEDER FORWARD SPEED ON CORN AGRONOMIC COMPONENTS
ABSTRACT Seed metering system and tractor-seeder forward speed are factors that affect sowing. Therefore, this study aimed to evaluate sowing and agronomic components of corn as a function of seed metering mechanism and tractor-seeder forward speed, in addition to evaluating the yield data obtained from a harvester with a yield monitor. The soil of the area

3. Data processing within rows for sugarcane yield mapping
ABSTRACT: The mapping of sugarcane yield is still not as widely available as it is for grain crops. Sugarcane harvesters cut and process the cane in a single or maximum of two rows, facilitating the monitoring of cane yield and its behavior on a small scale. This study tested a method for sugarcane yield data cleaning, investigating if the data recording fre

5. Correlation maps to assess soybean yield from EVI data in Paraná State, Brazil
ABSTRACT Vegetation indices are widely used to monitor crop development and generally used as input data in models to forecast yield. The first step of this study consisted of using monthly Maximum Value Composites to create correlation maps using Enhanced Vegetation Index (EVI) from Moderate Resolution Imaging Spectroradiometer (MODIS) sensor mounted on Ter

6. Cadmium phytoavailability in soils and evaluation of extractant effectiveness using an isotope technique
Large areas of land are nowadays contaminated by heavy metals and, it is therefore, important to monitor their levels in soils. Vegetables act as transfer mechanisms of such contaminants from soils to higher levels in the food chain. In this study, we aimed to evaluate the effectiveness of chemical extractants by the L-value method for Cd phytoavailability u

7. Uma análise do emprego no setor da construção civil nos estados do nordeste brasileiro: qualidade do emprego formal e o retorno da educação
The Construction Industry has gained prominence on the national scene due to its ability to generate employment, and absorb much of the disqualified labor. On that perspective, this research aims to measure the quality of formal employment and quantify the impact of schooling on income of Construction Industry workers in the states of Northeast Brazil. In or

9. RESPOSTA DE UM MONITOR DE PRODUTIVIDADE COM SENSOR ÓTICO A VARIAÇÕES DE PRODUTIVIDADE EM ARROZ IRRIGADO / RESPONSE OF YIELD MONITOR WITH OPTICAL SENSOR TO YIELD VARIATIONS IN IRRIGATED RICE CROP
A Agricultura de Precisão (AP) tem sido estudada principalmente nas culturas da soja, milho e trigo, sendo que seu uso tem sido crescente em lavouras comerciais. No entanto, na cultura do arroz irrigado, o uso dessa tecnologia ainda não foi devidamente avaliado, nem tampouco suas ferramentas, máquinas e equipamentos como sistemas para mapeamento da produt

10. Conceitos e considerações práticas do sistema de geração de mapas de produtividade na cultura de grãos.
ABSTRACT: Precison Agriculture adoption is increasing on savannas region in the central plain areas in Brazil, principally because fertilizers and others pesticides were saved reducing the cost of grain production in the agricultural areas. But environmental pollution with these products area also become a problem. It was estimated that the are with variable

11. Geração de mapas de produtividade para experimentos com milho no âmbito de fazenda.
ABSTRACT: Many farmers do not use precision agriculture tools due to high equipment costs and lack of knowledge about this new approach. A number of farmers have, however, conducted on-farm experiments without the help of these new and still expensive tools. One of most important equipments for precision agriculture practices is the crop yield monitor. It ca

12. Classificação não-supervisionada no delineamento de zonas de manejo.
RESUMO: O objetivo deste trabalho foi utilizar o método de classificação não-supervisionada (fuzzy K-means) em dados de produtividade para delineamento de zonas de manejo. O estudo foi conduzido a partir de dados georregerenciados de produtividade de grãos coletados por sensores e DGPS. Foram mapeadas três safras (milho-soja-arroz) em área de plantio
