economic considerations on wheat crops cultivated following soy crops on an argic chernosem in the transylvanian plain

In this study was tracked the effect of the nitrogen-phosphorous interaction in achieving wheat productions. The research presents the stated results as annual (partial) values and it will continue with them as being reference values for further experimental years (as stages in long term experiments) and with approaches that will economically substantiate the suggested solutions. The goal of this research is to scientifically and economically substantiate the differentiated fertilization systems involved in obtaining big productions in the reference area. In this study it was tried to track the effect of the nitrogen-phosphorous interaction in achieving wheat cultivated following soy productions, obtained in 2011 and 2013. The obtained results present the production levels obtained for wheat crops (Dumbrava Variety), the prior crop being soy. The already existing and further research will enrich the study’s utility in taking a rational fertilization decision based in the future also on the support of the suggested solutions.
