Resumo
The purpose of this study was to evaluate the effects of irrigation and application of
Organo-Minerals-Marine+Biotech (OMM-Tech) in yield and production efficiency of the Jatropha
curcas. The experiment was conducted in an experimental area located in Federal University of
Lavras, Brazil. A randomized block design with subdivided parcels and three replications was used.
The parcels 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 as powder + OMM-Tech in liquid form with a 2.5% concentration). The sub-
plots received two different water management treatments: with and without irrigation. A drip
irrigation system with emitters spaced by 0.50 m was used. It was evaluated productivity and
production efficiency of seeds in the first yield year. The plants irrigated and fertilized with 120 kg
ha -1 of OMM-Tech solid in soil showed better productivity.
