Conversely, the cost increases and profit decreases kg. In terms of energy due to the introduction of fertilizers, consumption kWh / ha reached 3761, and a ton of product consumption is 664 kWh. Net energy is 22,048 kWh / ha and energy efficiency 6, 86. In the third variant, doubling the amount of N, from 80 to 160 kg/ha, production increased only by 11.7% or 530 kg / ha, which further influenced the increasing cost and reducing profit per hectare. Energy consumption increased to 5862 kWh / ha, returning 947 kWh /t. The energy produced reaches 28 226 kWh / ha, net energy is 22,364 kWh / ha, while energy efficiency is 4.81. In the fourth variant, the tripling of the amount of nitrogen (240 kg N / ha) decreased from previous production to 170 kg or 3.7%. In these circumstances the cost of production increases and more profit per hectare is reduced and its rate also decreases, reaching 0.<strong>54</strong>%. Instead, as a result of tripling the amount of nitrogen, increases energy consumption 7914 kWh/ ha and at 1314 kWh per tonne yield also decreases to 3.46. In this case there are three avenues to be explored to draw a conclusion. The first way would be getting free fertilizer and irrigated production, so at minimal cost. A second way is to use moderate amounts of fertilizer and maximum effect. This is because the use of 240 kg N/ha, production began to fall from the variant with 160 kg N/ha. A third way is by providing prices that reward work effort and encourage producers to obtain high yields. So, more production, even with a higher cost, mass higher profit per hectare. In the case presented to the first variant, the third variant, the yield per hectare increased by 199 lei /ha. In the podzolic soils (Arges county) can be obtained by taking the best production of chemical fertilizers. Thus, the data presented in table 2, experiments conducted at SCDA Albota, that production can be almost doubled. In unfertilised variant could get a production of 4200 kg / ha, with a relatively low income (40 lei / ha), being the profit rate of 2.43%. From this level of crop production is becoming profitable. In terms of obtaining a price of 0.6 lei / kg, may return to start at 3000 kg / ha up. Productions 2000 - 2500 kg / ha, they get very many farmers - even most - especially in hilly areas or soils with low fertility, are unprofitable. In variants fertilized with nitrogen, applied in different eras, a fund of 100 kg P2O5 and 80 kg K2O / ha given in autumn, it is noted, however, a rebound of production when nitrogen is applied only in spring, even when administered in two stages. Administration of 1/3 N in the autumn has greater effect. From an economic perspective, costs are reduced to variants with partial nitrogen in the fall administration, and profit per hectare than 250 lei / ha. The profit rate is 13.05 and 10.93% to 3.28% for the variant with only nitrogen management in spring. 396
