Corn silage with its relatively high energy content is an important source of forage in the world. In
Turkey, silage corn has an important potential as a second crop under irrigated lands of semi-arid
regions. This research aims to study the effect of spraying Nano Fe2O3 on maize crop characteristics that
have grown for silage purposes under high pH soil conditions in Van city, Turkey. In the 2019 and 2020
summer seasons, Zea mays var. Tuono was planted with the spraying of Nano Fe2O3 arranged in
randomized complete block design with three replications at the Van Yuzuncu Yil University, Faculty
of Agriculture, Research and Application Farm of the Field Crops Department. Three different doses of
Nano Fe2O3 as (0.4, 0.6, and 0.8 mg. L-1) as well as control treated by tab water were sprayed two times
started at 54 days after planting and repeated after 15 days. The maize plant sprayed with Nano Fe2O3
compared to control improved the morphological studied character’s e.g. plant height leaves fresh
weight, cob weight per plant, shoot fresh and dry weight, and stem diameter in maize grown for silage
under alkaline soil conditions, except the number of leaves per plant and number of cobs per plant were
non-significant in both 2019 and 2020 seasons. Moreover, Fe2O3 increased inorganic chemical constitutes
of maize, K, Mg, Ca, Se and Fe while Cu, Mo, Zn, Mn, and P were non-affected at the dough harvest
stage. Application of 0.4 Fe2O3 recorded the highest values of growth and yield characters of maize for
silage purposes under high pH soil levels. Therefore, it might have the possibility of spray the Zea
mays plant with Nano Fe2O3 to improve tolerate of high pH soil stress and increase its silage quality and
quantity in Van, Turkey.
