The current two-year outdoor pot experiment study was conducted to explain the effect of Zn fertilizers types and application methods on the morphological characters, yield, and yield component of the Hashemi rice variety. The three factors factorial experiment was conducted in a completely randomized block design with three replications at the rice research institute of Iran in 2018-2019. The experimental factors were: Zn fertilizer types (four levels), application methods (three levels), and Zn deficit paddy soils (four levels). The results indicated that all fertilizer types and application methods significantly influenced the measured plant and soil characters. The most effective treatments on soil available Zn, plant height, total tiller numbers, panicle length, grain yield was the soil application of 20 kg Zn ha-1 in the source of Zn Sulphate by around 8.6 times, 10, 50, 29.3 and 50%, respectively, and also for straw yield was the three stages Zn foliar application in the rate of 0.5% in the source of Zn Sulphate by about 50%. Thus, it can be concluded that despite the various soil characters of the studied paddy fields, the soil application of 20 kg Zn ha-1 followed by the three stages Zn foliar application at the rate of 0.5% both in the source of Zn Sulphate can enhance the rice grain and straw yield considerably.
