Normally, any result achieved in experimental fields must be followed by an economical estimation which clearly highlights the economical advantages of new variants in crop technologies. The economical calculation allows the elaboration of a budget of expenses and incomes specific to each unit, so that, it takes into consideration the production cycle and the determination of production cost and possible incomes/area unit or tone of products. Similar researches were also performed in Mostistea Plain, for soybean, following the same aspects.The researches were performed during 2005-2007, in Mostistea plain, by a tri-factorial experiment, and the achieved results were technical-economically processed. For a beter relevance of the results, the calculation was achieved for the three years of experiment, in Euro, the utilization price being represented by Chicago’s quotation. It was also taken into consideration the value of subsidies from state budget, VAT difference, which increased the expenses in maize. All economical results were finally statistically processed.Within the research, a parallel between classical maize irrigation method (overhead irrigation) and modern one (drip irrigation) was performed.The researches, on the world plane, proved that drip irrigation is economically superior to overhead one.There were no similar researches in other areas of the country.The results allow, to farmers, to efficiently dose their efforts, based on principle “much more with much less” under the context of global crisis. The paper presents high originality degrees, there are no similar researches, till present, in Mostistea Plain.Having in view the high cost of irrigation water, the diminution of irrigation norm, by the most “high-tech” methods, has direct implications on economical indicators (production cost, benefit.

limited water supplying; watering rate; irrigation norm; water consumption; drought
