Abstract :
This study aimed to determine the correlation between relationship between grain yield and some yield components using correlation coefficients were use. Factorial experimental design was a randomized complete block design with three replications was conducted The factorials of the experiment, four levels of nitrogenous biologic fertilizers include: nitroxine, super-nitro plus, nitrocara and witness , and four levels of the phosphor biologic was include: fertile phosphatez , biozer, super plus and witness. There was The results showed that the nitrogen biological fertilizers and plant height correlation (0/533**) and in the use of biofertilizers Phosphor stem diameter (-0/491**), Head diameter of sunflower ( -0/563**), Thousand Grain weight (-0/331**) and Percent Fat (-0/412**) with negatively correlated obtained. But, There are, a positive correlation significant in use of phosphate fertilizers, oil Performance (1m2)(0/335*), Between grain yield and number of grains per sunflower Head (0/576**), Thousand Grain weight (0/519**), The biological function (0/319**), Harvest Index (0/716**), Protein Percent (0/480**), oil Performance (1m2) (0/825**), Protein function (1m2) (0/858**) There was a significant positive correlation And We have correlations between yield components as well as the positive and significant correlation between stem diameter with ( Head diameter of sunflower, Thousand Grain weight, Protein Percent, Percent Fat and oil Performance (1m2) ) Respectively (0/300**, 0/473**, 0/336*, 0/309*, 0/249*). Head diameter of sunflower with Protein Percent (0/328*), Percent Fat (0/290*) There is a positive correlation and number of grains per sunflower Head with Protein Percent (0/550**), oil Performance (1m2) (0/504**), Protein function (1m2) (0/617**) There is a positive correlation too. The biological function positively correlated Is with Thousand Grain weight (0285*) and Harvest Index (0/432**). between Harvest Index and number of grains per Head, Protein Percent, oil Performance (1m2) and Protein function (1m2) Respectively (0/545**, 0/298*, 0/501**, 0/578**) There is a high correlation.
