Daer Khadijeh,

I published a review on preharvest sprays and their effects on postharvest fruit quality last year (2013), but in my literature survey I did not find any report which used any of the minerals you mention. Or did you mean soil applications?

Best wishes,

Isabel

Hello Isabel

 The application of Iron chelate and ammonium nitrate were used as a foliar spray and in the soil respectively.

Thank you for your attention,

All right, then it scaped my survey. Anyway, I did not find anything related to the question of your interest, sorry.
