The Impact of Seaweed Extract and Biofertilizer on Root Growth and some Mineral Content of Orange Seedlings

Abstract

Abstract During the 2023 growing season, researchers from Tikrit University’s College of Agriculture’s Department of Horticulture and Landscape Engineering carried out the experiment. Orange seedlings’ root development and mineral content were intended to be studied in relation to seaweed extract and the mycorrhizal fungus biofertilizer. Here is a brief summary of the results: Significant increases of 2.85% in nitrogen, 0.56% in phosphorus, 2.67% in potassium, and 2.67% in the percentage of carbohydrates were observed in the leaves after applying seaweed extract at a concentration of 10 ml/L. The root mass as a percentage was 51.91%. The nitrogen concentration in the leaves increased by 2.59%, the phosphorus concentration by 0.51%, the potassium concentration by 2.51%, and the protein content by 2.51% after applying 10 grams of biofertilizer per seedling. Carbohydrates make up 16.31% of the plant, while leaves include 16.82% and roots 51.31 % of dry matter. At a concentration of 5 g seedlings per day, the nitrogen content in the leaves was much higher than 2.52%.
