Considerations Regarding a Comparative Economic Approach on Corn and Wheat Crops on a Representative Soil in Romania

The research refers on the production results obtained on corn crops (Turda STAR Variety) and wheat crops (Dumbrava variety) (cultivated following corn crops) conducted on an argyle chernozem soil in Cluj County, Romania. The study exhibits the differentiated fertilization systems (the effect of the nitrogen-phosphorous interaction) involved in obtaining high productions of wheat and corn in the reference area. For corn crops the rate of return, as a mean of all the values that derive from all nitrogen-phosphorous combinations was at a very high level, 80%, with a maximum of the individual values reached at the fertilizing combination N200P160, at which the value of the production increase due to the applied dose, reached the maximum value (6041kg/ha).. For wheat crops the rate of return, as a mean of all the values that derive from all nitrogen-phosphorous combinations was at a medium level, 58%, with a maximum of the individual values reached at the fertilizing combination N200P80, at which the value of the production increase due to the applied dose, reached the maximum value (2658kg/ha). Corn is not as sensitive as wheat to an imbalanced nitrogen-phosphorous (NP) ratio and responds to this through high productions even for nitrogen (N) overdoses that can sustain high and economic corn grain productions per surface unit.
