Effect of Foliar Application of Bimin221 and Seaweed Extract on Lime Seedling Growth

Abstract

This study was conducted in a certified citrus production nursery in Karbala province, Al-Hindiya district for the season 2020, on lime seedlings (Citrus aurantifolia) rootstock at the age of 6 months, It was sprayed with the nutrient solution Biumin 221 at concentrations (0, 1.5, 2, 2.5 m.L-1) and Basfoliar Kelp seaweed extracts at concentrations (0, 1.5, 3, 4.5) ml L-. The results showed that spraying the seedlings with single and combined study treatments led to a significant increase in all the vegetative and nutrition traits of lime seedlings. The treatment (2.5 g.L-1 nutrient solution + 4.5 ml.L-1 seaweed extract) achieved the highest averages in most of the traits. While the interaction treatment between the concentration (2.5 g.L-1 of the nutrient solution and concentration of 3 ml.L-1 of seaweed extract was excelled in the traits of leaf content of total carbohydrates, the percentage of nitrogen, iron, and zinc.
