The effect of Mycorrhizae symbiosis, soil and foliar spray of Flomix on grain yield and some qualitative characteristics of corn (Zea mays L.) in weeds competition

To study the interaction between mycorrhizae symbiosis, soil and foliar spary of Flomix on yield and yield components of corn (Zea may L.), an experiment was carried out as factorial based on randomized complete block design with three replications in Agriculture Research Staion of Shahrood University of Technology in 2014. The treatments included mycorrhizae symbiosis at two levels (non-application and application of mycorrhizae), foliar spray at three levels (non-application, once sprayed and twice sprayed) and soil spray at three levels (non-application, once soil application and twice soil application). The results showed that interaction between mycorrhizae symbiosis, foliar spray of Flomix indicate a significant effect on root colonization and grain P and increased this traits. Also root colonization and grain yield was affected by interaction between mycorrhizae symbiosis and soil spray of Flomix. Mean comparisons showed that Mycorrhizae application twice foliar spray of Flomix respectively increased root colonization and grain P from 37.22 percent and 1.83 ppm in non-application of mycorrhizae non-spray of Flomix to 67.22 percent and 5.06 ppm. Also Mycorrhizae application twice foliar spray of Flomix increased grain yield from 1144 Kg/ha in non-application of mycorrhizae non-spray of Flomix to 2155 Kg/ha.
