The effect of spraying with marine algae extract and adding Humax on growth traits of the roots of two varieties of pomegranate seed-lings

Abstract

The study was conducted for the period from 20/3 to 20/9/2023 to study the Effect of spraying marine algae extract and adding Humax on the growth traits of the roots of two varieties of pomegranate seedlings. The experiment was implemented relying on the completely randomized block design (RCBD) as a factorial experiment of three factors: the first was pomegranate varieties (Wonderful and Slimi), the second was marine algae extract with three concentrations (0, 1.5, and 3 ml L-1), and the third was Humax with three concentrations (0, 0.25, and 0.50 g L-1), comprising three replicates of each. On September 20 2023 measurements were taken and the results were analyzed according to the statistical design used, and the averages were compared according to the selection of the least significant difference and at the level of probability 0.05, and the most important results reached: The variety Wonderful was significantly superior to the Slimi variety in most root traits studied except the root diameter trait. The treatment of the marine algae extract at a concentration of 3ml L-1 showed significant superiority for all root traits studied, The Humax treatment at a concentration of 0.50 g L-1 showed significant superiority for all the root traits studied. The binary interaction between the varieties and the marine algae extract significantly affected all studied traits, as the variety Wonderful, when treated with 3ml L-1 increased in most root traits, while cultivar Slimi recoded highest average in the root diameter. The binary interaction between the varieties and Humax was significantly effective; when treating the variety Wonderful with 0.50 g L-1 of Humax increased all root traits significantly. The binary interaction between marine algae extract and Humax significantly affected all root traits. Treating seedlings with 3ml L-1 of marine algae extract and 0.50g L-1 of Humax.
