This study was conducted to determine the effect of foliar iron applications on fruit quality and yield of tomato under unheated greenhouse conditions. Tomato plants were treated with foliar iron applications at different concentrations (0, 500, 1000, 1500 and 2000 mg.l-1). Iron was applied with spraying eight times during the vegetation at 7-day intervals 40 days after planting. In the study, it was determined that foliar applications of iron showed positive effect on some fruit characteristics. Fruit number and yield of medium and large sized fruits were significantly increased in the 500 and 1000 mg.l-1 treatments, which subsequently resulted in an increase of marketable yield. Iron treatments had no effect on pH of fruit tomato. Whereas, firmness and total soluble solids increased with foliar iron sprays. According to our results, applications of 1000 mg.l-1 iron should be recommended in order to improve marketable yield in tomato production.

Abstract
This study was conducted to determine the effect of foliar iron applications on fruit quality and yield of tomato under unheated greenhouse conditions. Tomato plants were treated with foliar iron applications at different concentrations (0, 500, 1000, 1500 and 2000 mg.l-1). Iron was applied with spraying eight times during the vegetation at 7-day intervals 40 days after planting. In the study, it was determined that foliar applications of iron showed positive effect on some fruit characteristics. Fruit number and yield of medium and large sized fruits were significantly increased in the 500 and 1000 mg.l-1 treatments, which subsequently resulted in an increase of marketable yield. Iron treatments had no effect on pH of fruit tomato. Whereas, firmness and total soluble solids increased with foliar iron sprays. According to our results, applications of 1000 mg.l-1 iron should be recommended in order to improve marketable yield in tomato production.
