THE EFFECT OF SEEDLING AGE AND SPRAYING WITH AQUEOUS EXTRACT OF GARLIC CLOVES ON THE GROWTH CHARACTERISTICS AND YIELD OF TWO HYBRIDS OF BROCCOLI

Abstract

The experiment was conducted during the two agricultural seasons 2021-2022 and 2022-2023 in the field belonging to the Agricultural Research Station of the College of Agriculture, University of Basrah, Karma Ali, with the aim of studying the effect of two hybrids (Matsuri and 2004), three seedling ages (30, 45, and 60 days), and five concentrations of Aqueous garlic extract (10, 20) ml liter-1 of local variety garlic and (10, 20) ml liter-1 of Chinese variety garlic and the comparison treatment (0) There were 30 factorial treatments carried out as a split factorial experiment in a randomized complete block design. The Matsuri hybrid was significantly superior in plant height, main stem diameter, number of leaves, main disc weight, and plant yield. For both seasons, the Matsuri hybrid was significantly superior in plant height, main stem diameter, number of leaves, and Weight of main disc and yield of one plant , The 30-day-old seedling treatment also outperformed the study traits, and the spraying treatment outperformed significantly, as the 20 ml L-1 concentration significantly outperformed the study traits, and the interactions gave a significant effect in most of the studied traits, as the triple interaction outperformed the Matsuri hybrid plants that were planted at 30 days of age. Which was sprayed at a concentration of 20 ml L-1 , with a significant yield of 1.363 kg for the second season.
