An experiment was conducted in the one of unheated plastic house in Al- Abassia region belong Al- Najaf province during spring and autumn seasons 2015 and 2016 seasons, as a factorial experiment was carried out in Randomized Complete Block Design (R.C.B.D) with three replicates in two factors.

First factor was foliar spraying ( AL Jameah Liquid Fertilizer) in three concentrations i.e.(0, 5 and 10 )m.L-1.

Second was mineral fertilizers N, P, K with four levels i.e.

control treatment (without mineral fertilizer),100%,75% and 50% of recommendation fertilizer.

Mean were compared by using Duncan Multiple Range Test at probability 0.05.

Results showed that spraying foliar fertilizer at a concentration 10m.L-1 increased significantly in plant height 4.54 and 2.67m, number of the leaves 46.50 and 35.50 leave.plant-1, shoot dry weight 40.917 س 37.197gm, percentage for nitrogen in leafs and fruit 3.56س 3.46%, 1.89, 1.96% and total yield 13.22 and 4.11ton.

plastic house-1 for two seasons respectively, also complete mineral fertilizers recommendation(100%) treatment was supervisor significantly which gave 4.77 and 2.86m plant height, 49.56 and 38.56 leave.plant-1,27.611 and 25.101gm shoot dry weight, 3.66 and 3.53% percentage for nitrogen in leafs and 2.05 and 2.00% percentage for nitrogen in fruit and 14.04 and 4.25ton, plastic house-1 for two seasons respectively, compared to control which gave the lowest values.In addition, the Interaction treatment (spraying foliar fertilizer at a concentration 10m.L-1 and complete recommendation(100%) was supervisor significantly which gave 5.39 and 3.30m plant height, 52.67 and 41.67leave.plant-1, 57.000 and 51.818gm shoot dry weight, 3.91,2.16% percentage for nitrogen in leaf and3.65,2.24% percentage for nitrogen in fruit and 15.92 and 5.11ton.

plastic house-1 fruit yield for two seasons respectively , compared to control which gave the lowest values.
