Resposta da cultura de pinhão manso à irrigação e à adubação com OMM-Tech®

Abstract

The objective of this work was to evaluate the effects of irrigation and application of OrganoMinerals-Marine+Biotech (OMM-Tech® ) on Jatrophacurcasplants growth in an orchard in Lavras, MG, Brazil. A randomized block experimental design with subdivided plots and three replications was used. The parcels received two different water management treatments: with and without irrigation. 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® as powder + OMM-Tech® in liquid form with a 2.5% concentration). Plant growth was evaluated on: canopy and trunk diameters, plant height, and secondary branches number. The results showed that plants irrigated and fertilized with 120 kg ha-1 of OMM-Tech® powder form applied in soil showed better plant growth.
