Resumo
The purpose of this study was to evaluate the effects of irrigation and application of
Organomineral-Marine + Biotech (OMM-Tech) in yield oil of Jatropha curcas seeds. The experiment was conducted in an
experimental area located in Federal University of Lavras, Brazil. A randomized block experimental design with
subdivided parcels and three replications was used. The parcels received two different water management treatments:
irrigated and no irrigated. The sub-plots were submitted to different OMM-Tech fertilizer application methods: T1=
control (no OMM-Tech); T2 = soil application (120 kg ha -1 of OMM-Tech in a powder form); T3 = leaf application
(OMM-Tech in a liquid form with a 5% concentration); T4 = soil + leaf application (60 kg ha -1 of OMM-Tech in powder
form + OMM-Tech in liquid form with a 2.5% concentration). A drip irrigation system with drippers spaced by 0.50 m
was used. We evaluated yield oil of seeds in first production year. Jatropha trees irrigated showed a higher seeds oil yield
than no irrigated trees. However, fertilization with OMM-Tech no influenced seed oil yield. Seeds oil yield of jatropha
trees irrigated was 34%, and no irrigated 27%.
