Abstract
The sunflower oilseed and confectionaries types (Helianthus annuus L.) are definitely different in nutritional responses. This study attempted to evaluate differences in the expression levels of phosphorus and zinc arising from different fertilization treatments. The field experiment was conducted out at Agricultural Research Centre, in Islamic Azad University Arak, Iran, during 2011. Experiment was laid in split plot in randomized complete block design with 3 replications. Phosphorus treatments were in main plots and zinc in sub plots. Phosphorus levels were including 350, 175, 175 kg/ha triple super phosphate plus 100 g/ha phosphorus solublizing bacteria (PSB) and PSB alone and zinc levels were 0, 25 kg/ha soil application zinc sulphate, 25 kg/ha soil application of zinc sulphate plus 10% soluble zinc foliar application and soluble zinc foliar application alone. The results of roots quality in two sunflowers types showed P concentration in confectionary sunflower roots in all zinc levels was significantly higher. Use of 175 kg/ha triple super phosphate plus phosphorus solubilising bacteria (P3( or utilization of pure PSB (P4) in test plots was one of the main cause to increase phosphorus concentration in sunflower roots in check plots for zinc (Z1). Leaf phosphorus content was sharply higher in confectionary sunflower when fertilized with phosphorus and zinc mixture. High P application (P1) was the main cause for slow reduction in leaf zinc concentration for oilseed from 40 to 20 mg/kg. However, PSB and chemical phosphate use (P3) and PSB alone (P4) caused the leaf zinc content to increase significantly by foliar zinc application (Z4). Furthermore, the most zinc accumulation was detected in confectionary sunflower seeds by 55 mg/kg in PSB and chemical phosphate use treatment plus foliar soluble zinc application (P3Z4).
