Abstract

In order to determine the effect of zinc and manganese foliar application on spring maize hybrids in northern Khuzestan, a factorial experiment in a randomized complete block design with four levels (pure water spraying, zinc spraying, manganese spraying, and zinc and manganese spraying) as the first factor and two hybrids (Single Cross 704 and Single Cross Caroon) as the second factor with three replications in the region Shams Abad Dezful was executed. Results showed that foliar application of Zn + Mn on plant height, leaf area index, ear length and protein percentage were significant at 1% probability level.The hybrid was significant at plant height, leaf area index and ear length at 1% probability level and at 5% protein level.. The interaction between foliar application and hybrid on plant height, leaf area index, probability level of 1% and protein percentage was significant at 5% level.
