Citriculture is one of the most important agricultural activities in the North of Iran,Citrus trees are perennial evergreens that are successfully grown in both arid and humid climates The Thomson navel orange variety has been introduced in this region recently and it may become an important variety in the near future In order to evaluate bio stimulator influences to increase of yield, fruit quality we investigated the effects of this fertilizer on the fruit productivity responses of Thomson navel orange trees The experiment was conducted on Thomson navel orange (Citrus, sinensis(L.)osbeck) on Poncirus rootstocks were planted in Citrus research institute spacing 6 .7 m in 1375.and grown in loamy soil in the experimental Research Station of the Citrus Research Institute .The experiment consisted of 12 treatments,. Treatments were randomized in 3 blocks with 12 trees in each block. the applied treatments in each season involved the following: T1)control T2) Foliar application of 7 ml elfer citrics in litr water. T3)Foliar application of 300 ml biofol K in 100 litr T4) Foliar application of 400 ml biofol Zn in 100 litr water. T5) Foliar application of 300 ml biofol P in 100 litr water. T6) Foliar application of 400 ml biofol ca in 100 litr water T7) Foliar application of 400 ml biofol 8-8-8 in 100 litr water. T8) Foliar application of 700 ml elfer fruits in 100 litr water. T9) Foliar application of 50 ml bioroot in 100 litr water. T10)Foliar application of 300 ml vitaminoelfer in 100 litr water. T11) Foliar application of 150 ml micromax in 100 litr water. T12) Foliar application of urea plus magnesium sulfate plus zinc sulfate500 ml in 100 litr water.Trees were of normal growth,uniform in vigor under rain fed irrigation and received normal fertilization and cultural practices as scheduled in the program of the station. fruit was harvested and samples were collected for physical ,chemical and organoleptic evaluation . The results indicate that foliar application significantly increased yield, Thus,in this study to apply 400 mililitre biofol ca foliar spray treatment could be recommended from results as they signifigantly increased productivity of navel orange trees.
