Research on corn hybrids behavior under the application of new technological concepts in Osmancea-Constanta area

The emergence of new growing concepts aiming to achieve the biological yield potential of crops, soil conservation and the increase in economic efficiency, had also an echo in the agriculture of Dobrogea area. Farmers were involved in finding the best solutions to achieve these goals. Research conducted at SC Micul Agricultor SRL farm, located in Osmancea, Constanta County is an example in this direction. This research aimed to establish the corn hybrids best adapted to the climatic and pedologic conditions of the area, and the most efficient soil tillage system and to optimize crop fertilization. For this purpose, the behavior of Mas 40 F, Dartona and P 9911 corn hybrids was studied under conventional (plowing) and minimum soil tillage (tiger and disk) for the following fertilization levels: unfertilized, N90P40K40 and N90P40K40 + Greenstart - 25 kg/ha.The best results were obtained when using tiger to perform basic soil tillage and fertilizing with N90P40K40 + 25 kg/ha Greenstart. For this variant, all hybrids had the highest yields ranging from 13.56 to 13.93 t/h
