In order to study of the interaction between mycorrhizae symbiosis, soil and foliar spary of Flomix on yield and yield components of corn (Zea may L.), a factorial experiment was carried out based on Randomized Complete Block Design (RCBD) with three replications in Agriculture Research Staion of Shahrood University of Technology in 2014. The treatments included mycorrhizae symbiosis at 2 levels (check and application of mycorrhizae), foliar spray at 3 levels (check, once sprayed and twice sprayed) and soil spray at 3 levels (check, once soil application and twice soil application). The results of variant analysis showed that interaction between mycorrhizae symbiosis, soil and foliar spray of Flomix significantly increased biological yield, harvest index, 1000-seed weight, grain nitrogen content, and number of row per ear traits. Also grain yield and number of seed per row was significantly affected by interaction between foliar spray and soil spray. In addition, interaction between mycorrhizae and foliar spray significantly affected on seed depth trait. Mean comparisons showed treatments combination of twice foliar spray+twice soil spray of Flomix increased seed per row and once foliar spray+twice soil spray of Flomix increased grain yield. According to the mean comparisons results, treatment combination of foliar spray + once soil spray flomix let to 2090 kg.h-1 grain yield. The lowest grain yield obtained from check treatment 1444 kg.h-1. The highest biological yield equivalent to 6557 kg.h-1 resulted from treatment combination of mycorrhizae symbiosis + twice foliar spray + once soil spray of flomix and the lowest biological yield equivalent to 3190 kg.h-1 obtained from chck treatment.
