Response of Matthiola Incana L. to Spraying with Amino Acids and Nano-Chelated Iron in Growth and Flowering Indicators

Abstract

Abstract The experiment was carried out in the nursery of University of Kufa during the agricultural season 2021-2022 to study the response of stock plant to spraying with amino acids and nano-iron in growth and flowering indicators. experiment was conducted based on RCBD with three replications The concentrations of amino acids were 0, 1.5 and 3 ml l−1 and 0, 20 and 40 mg l−1 of nano-iron. The obtained results confirmed that spraying amino acids at a concentration of 3 ml l−1 with nano iron at a concentration of 20 mg l−1 led to a significant increase in plant height, total number of leaves, leaves content of total chlorophyll, total soluble carbohydrates, number of inflorescences, number of florets, flower diameter and inflorescence length, compared to the control treatment.
