Abstract:
The research was conducted at the Stekhers Research Station of the Agricultural Scientific Research Center in Lattakia in 2020, to study the effect of two types of nitrogen fertilizers (ammonium sulfate [(NH4)2SO4] 71.4 kg/d- potassium nitrate [KNO3] 107 kg/d) on growth and productivity parameters on the concentration of some nutrients for two types of Yellow maize cultivar Dina F1 (foreign) and Fayhaa cultivar (local) grown in calcareous soil in addition to the treatment of the control without adding nitrogen, at a rate of three replications for each treatment. The results also showed that the ammonium sulfate treatment increased the availability and absorption of some nutrients in corn plants through its effect on pH, and the two studied cultivars (Dina F1 and Fayhaa) are tolerant to high calcium carbonate levels. The treatment of cultivar Dina F1 with ammonium fertilization was superior to all treatments in all studied productive indicators: cob weight, cob length, number of grains per cob, and dry weight of 100 seeds.
Keywords: Zea Maize, Dina F1, Faihaa, nitrogen fertilizer, nutrient, Calcareous soil.
