Effect of ground addition and spraying with ALGA seaweed extract on the chemical traits of Citrus aurantium seedlings

Abstract

A factorial experiment was conducted in lathhouse covered with saran affiliated to Al- Musayyib Technical College at the age of 2 years planted in plastic anvils during the growing season 2021  to study the effect of ground application and spraying with seaweed extract with concentration (0,15,20,25) cm ³ / L for both addition methods and the interaction between them in the vegetative growth and chemical traits under study of citrus seedlings, and using the randomized complete sector design with three replications. The results showed significant differences when ground application and spray addition of algae extract in vegetative and  chemical traits under study. The ground addition achieved 25 cm³ / L had the highest average values ​​for the studied traits, while the comparison treatment gave the lowest values ​​for traits under study
