Resumo
This research was carried out through an agreement among
Escola de Agronomia e Engenharia de Alimentos – Universidade
Federal de Goiás, Empresa Brasileira de Pesquisa Agropecuária
– Embrapa Arroz e Feijão, and Agência Goiana de Desenvolvimento
Rural e Fundiário, in the municipality of Goiânia, Goiás
State, Brazil. The objective was to develop a human traction bar
sprayer prototype, equipped with hydraulic nozzles, and evaluate
its performance. The measured variables were: work performance
(ha.h-1), spray drop density (drops.cm-2), and spraying deposit
(ng.cm-2). The developed prototype has performed satisfactorily.
Water sensitive paper cards and micros-cope plates, laid over the
soil, were used for spraying sampling and drop distribution
sampling. Evaluations were made in just tilled soil, pasture, and
corn, beans and rice crops. The sprayer developed an average
1.18 ha.h-1 work performance, 81.46 drops.cm-2 drop density,
and 64.84 ng.cm-2 of recovered product at soil level.
