In order to evaluate the efficacy of ferrous and manganese sulfate elements on yield and biomass of tomato in greenhouse conditions this research was performed in Yasuj during crop year of 2012-2013. An experiment was conducted as factorial on the basis of complete randomized block design with three replications. The factors of studied included ferrous sulfate, manganese sulfate, each at 3 levels (0, 3000 and 6000 ppm). Data were analyzed using SAS software and mean comparison of data was conducted through Duncan test and drawing graphs through Excel software. The analysis of data variance showed that the interaction of various levels of ferrous sulfate and manganese sulfate had significant effect on measured traits (Root fresh weight, shoot fresh weight, shoot dry weight and fruit fresh weight) Also, these increased compared with control. Based on the findings of this study, interaction of factors indicated the best results. The best treatments in present study were interaction of 6000 ppm of manganese sulfate with 6000 ppm of ferrous sulfate (Mn6 Fe6) which is recommended for growing greenhouse tomatoes.
