Study of increase possibility in confectionary sunflower yield by phosphorus solublizing bacteria and zinc application

The experiments to evaluate the possibility of enriching sunflower seeds nuts on the farm by bacteria release phosphorus sulfat, In a randomized complete block design with three replications in a split plot, Arak Islamic Azad University Research Farm in 1390 was carried out. Factors include four levels of P (P1, P2, P3 and P4, respectively, 350 kg ammonium phosphate ha175 kg ammonium phosphate, ammonium phosphate and 175 kg P -2 reproductive biology, biological phosphorus fertilization -2) and four levels of zinc(Z1, Z2, Z3 and Z4, respectively, of zinc sulfate, zinc sulfate 25 kg ha sprayed on with a concentration of 10%, 25 kg ha sprayed zinc and zinc) were considered. Foliar application of zinc and phosphorus-releasing bacteria in the field, In the pre-flowering and 10 days after return again.The grain yield per hectare, biological yield, head diameter, harvest index, The grain yield per hectare, biological yield, head diameter, harvest index, The results showed that the highest yield of 50% ammonium phosphate ha treated with biological phosphorus fertilization -2 And application of zinc dust consumption of 78/5632kg ha treatments applied at 50% -2 Biological phosphorus fertilized with ammonium phosphate with zinc sulfate soil and foliar application of zinc Rate of 52/5493kg per hectare, respectively.
