Effect of Spraying a Combination of Nano-Fertilizers on some Vegetative and Root Growth Characteristics of Two Pomegranate Cultivars under Salt Stress Conditions

Abstract The research was conducted in the vegetable canopy of Department Horticulture and Landscape Engineering - College Agriculture University Karbala for period from beginning March to October 2021, with aim knowing effect spraying a combination nano-Fertilizers on growth seedlings two pomegranate cultivars under salt stress conditions. first factor nano-fertilizers at concentration (0 ml. L -1 Optimus plus 0 g. IQ combi 1 + 0.5 1.5 ml gl combi). As second factor, variety (Wonderful, Slimy), third irrigate three different concentrations (1.7, 5, 10 dS.m ). results can be summarized as follows: (1) treatment nano-fertilizer (1.5 ml.L gL combi) had highest rate trait (plant height, stem diameter, leaf area, dry weight shoot root system, fresh group). root, length) (1 recorded number leaves characteristic. (2) cultivar Wanderfel outperformed Salimi increase leaves, length). (3) Irrigation electrolyte water (1.7 decimens.m ) showed values vegetative characteristics (4) double triple interactions between study factors led clear significant superiority studied traits compared comparison treatment. 7. Decimens.m-1) significant, giving most traits. ml.l combi, Wanderful salinity irrigation 1.7 dSm average leaves.
