The Role of Bactosan and Zinc Fertilization on some Vegetative and Chemical Characteristics of Broccoli Brassica Oleracea var. Italica

Abstract

Abstract In the Department of Horticulture, College of Agriculture, University of Karbala, Iraq, a field experiment was conducted to study the role of Bactosan and zinc spraying on broccoli’s vegetative and chemical properties for the 2021-2022 agricultural season. Bactosan concentration (0, 6, and 8 L h-1) and zinc concentration (0 and 1 g L-1) were two factors in an experiment with a randomized complete block design (RCBD). Three replications were used to test each of these factors. The investigation results were reached: Bactosan displayed a significant effect at 8 L h-1 on vegetative and chemical traits, while at concentration 0 L h-1 had the lowest rates. Spraying with zinc at concentration 1 g L-1 increased plant height, stem diameter, leaf area, vegetative dry matter weight, and chemical characteristics. Note that concentration 0 g. L-1 gave the lowest rate in the traits mentioned above. The interaction between Bactosan and zinc showed a significant increase in all vegetative and chemical features when the exchange at 1 g L-1 and 8L h-1, which gave the highest indicators in (plant height, stem diameter, leaf area and number of Leaves, dry weight of shoots, chlorophyll content of leaves, percentage of ascorbic acid, percentage of carbohydrates and rate of protein in curd head). Based on these findings, we may conclude that Bactosan and zinc contribute to an improvement in broccoli’s chemical features and its vegetative development characteristics.
