Zardasht K50 is a very high potassium content liquid fertilizer. It has a significant effect in growth period, product quality and resistance against all types of biotic stresses. The best time to use this product is in early flowering stages and after formation of fruits. This fertilizer prevents product loss during fruit making.


  • It is used in plants deficient in potassium or when the potassium supply from the soil isn’t adequate for plants.
  • Using this fertilizer during cold and freezing weathers causes vegetable juices to concentrate which prevents frostbiting.
  • Application rates are for guidance only. Actual rates will vary with local growing conditions, soil analysis and plant’s age. It is compatible with most fertilizers and pesticides.
