1. COST OF AERIAL AND GROUND SPRAYINGS AND TECHNOLOGICAL REPLACEMENT POINT: A CASE STUDY IN THE REGION OF MINEIROS, GO, BRAZIL
ABSTRACT One of the main costs in agriculture is related to mechanized operations, which, in turn, are associated with the capital invested in machinery and equipment, the scale of production, and the operating efficiency. Thus, the choice of technology to carry out these operations must take these factors into account to minimize the production cost. In thi

3. OPTIMIZATION MODEL FOR VEHICLE ROUTING AND EQUIPMENT REPLACEMENT IN FARM MACHINERY
ABSTRACT: An equipment replacement decision takes into account economic engineering models based on discounted cash flow (DCF) such as the Annual Equivalent Cost (AEC). Despite a large number of researches on industrial assets replacement, there is a lack of studies applied to farm goods. This study aimed at assessing an alternative model for economic decisi

6. A cost prediction model for machine operation in multi-field production systems
ABSTRACT Capacity planning in agricultural field operations needs to give consideration to the operational system design which involves the selection and dimensioning of production components, such as machinery and equipment. Capacity planning models currently onstream are generally based on average norm data and not on specific farm data which may vary from

7. Heat pump for thermal power production in dairy farm
ABSTRACT Besides cold for milk cooling, dairy facilities need to produce hot water for cleaning of tools and equipment. Overall, ohmic heating has been used in dairy farms, increasing power consumption and manufacturing costs. Therefore, as an alternative to reduce power consumption, this paper proposed a water-water heat pumping for simultaneous cold and he

8. Gestão financeira e econômica da propriedade rural com multiproduto
Farmers have always neglected management procedures in their enterprises in detriment to initiatives regarding production technology. Overall, producers and technicians know the answer to what, how and when to produce, but they dont know the cost or profitability of this technology. The present study shows the importance of the sustainability of agricultural

9. Estudo das alteraÃÃes hematolÃgicas, bioquÃmicas e genotÃxicas induzidas por agrotÃxicos em agricultores do estado do Piauà / STUDY OF POSSIBLE GENETIC CHANGES INDUCED BY PESTICIDES IN FARMERS IN THE STATE OF PIAUÃ
Exposure to pesticides represents a potential risk to human health. In addition to poisoning, these compounds may interact with DNA, causing degenerative diseases, including cancer. The risk assessment for pesticides was conducted in the municipalities of Picos, Piripiri, Barras and Josà de Freitas with farm workers (exposed group) and 55 administrative off

12. 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
