Response of Gazania Plants (Gazania Splendens L.) to Seaweed Extract (Tecamin Algae) and Nano Stimulator (Proteck CalBor)

Abstract

Abstract The study was conducted in the lath house of the Department of the Horticulture and Landscape - College of Agriculture during the growing season of 2020-2021 inGazania plants, in order to study the effect of ground addition of marine algae extract (Tecamin Algae) at concentrations (0, 2 and 4 ml L-1), symbolized by (A0, A1 and A2) respectively, and spraying with the nanostimulator (Proteck CalBor) manufactured according to nanotechnology in concentrations (0, 0.5 and 1 ml L-1) and it has a symbol (B0, B1 and B2). The results showed that the treatments of adding the extract (Tecamin Algae), especially at concentration A2 (4 ml L-1) contributed to achieving the best results for all vegetative and flowering growth traits (plant height, number of leaves, vegetative dry weight, number of offsprings, leaf content of chlorophyll, total carbohydrates content of leaves, number of flowers, flower fresh weight, flower diameter, flower peduncle length), they were (13.65 cm, 34.64 leaf plant-1, 6.38 g, 7.72 offspring plant-1, 10.94 mg g-1, 7.44%, 5.56 flower plant-1, 2.26 g, 6.08 cm and 9.75 cm), respectively. A Spraying with nano stimulator (Proteck CalBor) achieved significant effect, especially B2 (1 ml L-1) concentration, that gave the highest values for the traits (plant height, vegetative dry weight, number of off springs, leaf content of chlorophyll, total carbohydrates content of leaves, number of flowers, flower fresh weight and flower diameter), they were (13.38 cm, 6.47 g, 7.48 offspring plant-1, 10.61 mg g-1, 7.49%, 5.40 flower plant-1, 2.41 g and 6.40 cm), respectively.
