Produtividade e rendimento de sementes de pinhão-manso submetido à irrigação e adubação com OMM-Tech

Abstract

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.
