The effects of foliar nano-fertilizer and seaweed extract on the growth and nutrient status of Pistacia seedlings
Abstract
This study was conducted to determine the effects of nano-fertilizer foliar application of Loenergy Plus® and seaweed extract on Pistacia vera L seedlings. The experiment was conducted under a vegetable lath house at department of Horticulture and landscaping, college of Agriculture, University of Kerbala. The objective was to rapidly achieve mass production of strong seedlings that acclimate to different external environments. The research tested three levels of seaweed extract (0, 1, and 2 ml L⁻¹) and three levels of Loenergy Plus® (0, 0.5, and 1 ml L⁻¹). The following parameters seedlings height, stem diameter, leaf area, total chlorophyll concentration and stored: nutrients (nitrogen, phosphorus and potassium) were recorded Both Loenergy Plus® and seaweed extract significantly enhanced seedling height (up to 41.44 cm), stem diameter (0.72 mm), leaves number (46.48 leaves plant⁻¹), leaf area (23.44 cm²), chlorophyll content (53.65 SPAD), and leaf N (2.83%), P (0.33%), and K (1.84%) concentrations. The best results were obtained with 1 ml L⁻¹ Loenergy Plus® combined with 2 ml L⁻¹ seaweed extract is actionable for nurseries, with all main effects and interactions significant (p≤0.05). It appears that a combination of nano-fertilizers and Seaweed extract might be effective in promoting the growth, vigor, and nutrient status of Pistacia seedlings.
