Effect of integrated fertilization between foliar and soil in some parameters of growth and yield of Cucumber Cucumis sativus L. under unheated plastic house condition

Abstract

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 , 37.197gm, percentage for nitrogen in leafs and fruit 3.56, 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.
