Foliar Spraying of NPK to Relieve Salinity Stress on Tomato Plants

Abstract

A pot experiment was carried out to study the effect of NPK foliar spraying on salt tolerant of tomato plants. Seedlings were grown in plastic pots 30 cm, filled with loamy sand soil. Seedlings were irrigated every week with saline two type’s salts (NaCl and CaCl) at two levels 2g and 4g L. Seedlings were sprayed with foliar spraying containing NPK. Two months later from transplanting of seedlings leaf samples were taken for determination nutrient contents. The result showed that NPK foliar spraying had a positive effect on soil, growth development, yield and the nutrient concentrations in leaf plant of tomato under the impact of adverse salinity. Although the salts levels of soil have an effect on the absorption of nutrients by tomato plant. But, foliar spraying has a positive effect on the concentration of N, K, Ca, Fe, Mn and Cu in plant leaves.
