摘要：The paper aimed to predict gross margin based on wheat yield, using a sample of 14 farms dealing with wheat cropping in the South Plain of Romania. The data were collected for the year 2010 and refer to 1 ha. The average values for the main indicators taken into consideration were 4,396.42 kg wheat grains/ha, Lei 3,433.78/ha gross product, Lei 1,580.50/ha variable costs and Lei 1,988/ha gross margin. The linear regression function Y= -544.33+0.576 X was used in order to forecast wheat gross margin for a wheat yield scale ranging between 4,400 and 6,000 kg/ha. As a conclusion, for an increase by 100 kg wheat yield per ha, gross margin will raise by Lei 57.6/ha
