Abstract

Salinity stress and micro-nutrient deficiency are the most important factors limiting quantity and quality production of corn silage (Zea mays L. ) in calcareous soils in the central area of Iran. Therefore, in order to evaluate the effect of application method of iron (Fe) and zinc (Zn) fertilizers on yield and chemical composition of corn silage under saline irrigation water, a 1-year factorial experiment was conducted based on randomized complete block design with three replications at Arsanjan, Fars province in 2014. Treatments were at three levels of saline irrigation water (2, 4, and 6 dS m-1) and 12 application methods of Zn-Sulfate, Fe-sulfate, and Fe-Chelate fertilizers. Results showed that increasing salinity stress from 2 to 6 dS m-1 decreased silage corn and ion contents such as potassium (K), phosphorus (P), calcium (Ca), copper (Cu), manganese (Mn), Fe, and Zn by 12. 5 and 43%, respectively. The highest silage corn (71. 77 Ton ha-1) was obtained by soil application of Fechelate and Foliar spray of Zn-Sulfate under saline irrigation water at 2 dS m-1 treatment. Under saline irrigation water at 4 and 6 dS m-1, soil application of Zn-Sulfate and Fe-Chelate accompanied by Foliar spray of Zn-Sulfate and seed-treatment with Fe-sulfate maximized silage corn. Results showed that combined application of micro-nutrient such as Fe and Zn elements compared to separate application method efficiently increased quality and quantity of silage corn under saline irrigation water at 6 dS m-1. Overall, selection and use of the correct fertilizer application methods are important for garneting the silage yield and quality of corn under saline condition and to decrease non-saline water use.
