The aim of the paper is to present research on the testing of maize hybrids in the pedoclimatic area of Ohaba Forgaci, with a view to introducing them into culture and optimizing some technological chains in order to obtain economic and high-quality harvests; 11 maize hybrids from almost all maturity groups were tested. The maize seed used in the research tests had a high cultural value, in accordance with regulations currently in force. The conducted research was single-factor experiment carried out during 2018-2019 regarding the specification of technological chain particularities relevant for corn, specific for Ohaba Forgaci. From a geomorphological point of view, the researched perimeter is part of the physical-geographical unit "Banat-Crişana" which is situated in intermediate relief steps between the Western Carpathians and the edge of the Pannonian depression. The following main forms of relief are found in the respective sector in which the researched perimeter is located: hill, terrace, alluvial plain, meadow. From a thermal and rainfall point of view, the studied perimeter displays a temperate continental climate. The annual value of the aridity index "de Martonne" is 33.3 (exoreic regime), and for the annual hydro-climatic index the value 100 was obtained, a typical value for a balanced hydrological figure. The experiment was organized on a vertic-stagnic preluvosol type of soil, medium loam-clay / medium clay-loam, on medium-fine swelling clays from Ohaba Forgaci.
