The Impact of Spraying Pomegranate Seedlings Salimi Cultivar with Various Plant Extracts on Their Development

Abstract

Pomegranate seedlings of the Salimi cultivar were brought from the nursery at the Indian gardening station in Karbala province and planted in the field at the College of Agriculture at Al-Qasim Green University in the middle of November 2021. Since 30 uniformly growing seedlings were chosen, and all service activities, including watering and weeding, were carried out in an even fashion. Only one seedling was used as the experimental unit in this randomized, double-blind, completely-block-design factorial experiment (3 * 5). The effects of natural aqueous extracts of three types of cumin, black cumin, and coriander seeds at three concentrations (00, 5, and 10 g.L-1) on plant growth were studied. The statistical analysis revealed that the black cumin treatment at a concentration of 5gml-1 with coriander extract at a concentration of 10 g.L-1 (B5Z10) resulted in the highest plant height (79.5), the highest number of branches (5.50%), and theWhen compared to the control treatment, the black cumin treatment with a concentration of 5 gm L-1 with cumin extract at a concentration of 10 gm L-1 (B5K10) obtained the highest length of branches reaching 8.88 cm, and the individual treatments of spraying with black seed extract (B) or spraying with cumin extract (C) achieved the highest relative content of chlorophyll in the leaves, which amounted to 51.22 SPA units.
