RESUMEN
Objective is to analyze the economic feasibility of implementing a greenhouse in a hydroponics production system in substrate (sand) on a small family farm as an alternative to hydroponic cultivation using nutrient film technique (NFT). This case study was carried out in the Municipality of Dourados, Mato Grosso do Sul state, Brazil. The location was specifically selected because of the importance of agricultural activities and the need for productive diversification related to the context of the small rural producer. As a criterion for assessing economic viability, the techniques of net present value (NPV), internal rate of return (IRR), modified internal rate of return (MIRR), cost-benefit (C/B), profitability index (PI), equivalent annual value (EAV) and discounted payback (DP) were under consideration. A minimum attractiveness rate adjusted to the risk of emerging countries of 10.25% per year was considered. The viability of the project was verified, even when exposed to risk and uncertainty.

Entretanto, todas as médias das subescalas apresentaram diferenças estatísticas, sendo que a subescala repercussões emocionais no trabalho apresentou maior significância. Conclusão: a equipe de enfermagem do serviço privado apresentou maiores médias de sobrecarga.
