摘要：The paper aimed to determine the correlation between average production, gross product, variable cost and gross margin for wheat and maize crops cultivated in 4 farms situated in the Southern Plain of Romania in the agricultural year 2010-2011. The correlation between wheat yield and gross margin was a strong one, rXY=0.598 and in case of maize rXY= 0.862 showing a very strong connection. According to "Student Test" for DL=3, the values of the calculated rXYwere higher both for P=99% and P=95% showing a significant relationship between the analyzed indicators. As a conclusion, for increasing gross margin, farmers have to grow up gross output coming from marketed production and reduce variable cost
