In order to study the effects of foliar application of sucrose boron, potassium nitrate and salicylic acid on yield and yield components of tomato, a four replicated, factorial arranged RCB design experiment was conducted in Daland industrial agricultural farm, in Golestan province during 2013. In this study, the first factor was foliar application of sucrose at four levels (0, 5, 10 and 15%) and the second factor was the combination of boron as boric acid, potassium nitrate and salicylic acid at four levels (0, 0.2% boron, 0.2% boron + 1.9 % potassium nitrate and 0.2% boron + 1.9 % potassium nitrate + 0.013 % salicylic acid). The first foliar application was treated 20 days after transplanting and was repeated every 15 days (seven times foliar application). The results showed that some quantitative traits such as fresh and dry weight of aerial parts were not significant and the highest fresh and dry weight of underground parts was attributed to the control. The highest values related to some qualitative traits such as leaf area, average yield per harvest and ratio of fertilized to non- fertilized flowers were related to presence of boron. Finally, 0.2% boron was selected as the best treatments in respect to obtaining the highest yield and 15% sucrose+ 0.2% boron was selected as the best treatments in respect to obtaining the highest size and weight of the fruit for fresh consumption, respectively.
