Abstract :

In order to evaluate the changes obtained from nitrogen, zinc and potassium sources on the morphophysiology of hybrid Maize SC704 experimental in the form of complete randomized block design in four replications was conducted in spring and summer of 2018 in Golestan province in an area located in Mazraeh Katoul. The treatment included nitrogen fertilizer, potassium, zinc alone, nitrogen + potassium, nitrogen + zinc, zinc + potassium, combined use of nitrogen + potassium + zinc, versus control. The results of analysis of variance showed that the treatments on grain yield, plant dry weight, corn length, chlorophyll a, chlorophyll b, total chlorophyll, silk soluble sugars and silk protein were significant at a probability level of one percent. Application of these fertilizers increased corn length, plant dry weight and grain yield, as well as increased sugars and silk protein of corn and photosynthetic pigments of corn and the highest content of photosynthetic pigments was observed in the treatment of application of potassium fertilizer alone and combined application of fertilizers (Zn + K+ N).
