摘要：

Maize is a staple food worldwide, and the issues of growing it in current drought-oriented scenario of climate change rise challenges in agricultural practices, especially fur the rainfed agriculture that is widely extended in Romania. The current paper presents the results of a field research conducted daring 2017 and 2018 at Moara Domneasca Didactic Farm, located in Southeastern Romania, aiming to highlight the influence of technological factors, as fertilization and hybrid, on maize yield recorded in minted conditions. Rainfalls capitalization by the maize crop shows yield increases between 25.2 kg and 37.8 kg grains per mm rainfalls, depending on hybrid and fertilization rates. The highest yield is recorded by the hybrid DK 5086 (8512,7 kg/ha) at the fertilization level N80P40. Yield growth generated by mineral fertilization recorded an average value for the researched hybrids of 14.1 kg per kg of nitrogen applied and of 9.1 kg per kg of phosphorus.
