BIOFORTIFICATION OF WHEAT PRODUCTIVITY USING HUMIC ACID, ZINC AND AMINO ACIDS APPLICATION
Abstract
Soil application of humic acids (HA) and foliar fertilization with bio-stimulants as Zn and amino acids, and others can affect plant growth by enhancing resistance to abiotic stress and raising and sustainably increasing grain yield. Consequently, this investigation was carried out to test the response of Bohoth-210 wheat variety to soil-application of HA and foliar application of Zn and amino acids (AA) and their interaction on yield and yield components during the cropping season of 2023/2024. The factorial experiment was designed according to a complete randomized block design (CRBD) in two factors. The first factor was the application of HA as a soil amendment, with variable levels of application set at 0, 7, and 14 kg/ha. The second factor was the foliar spraying levels of (water as a control, Zn at a rate of 1.5 kg/ha, amino acids at a concentration of 1 cm/liter of water), and a combination treatment of Zn and amino acids. These treatments were randomly distributed in three replicates. The findings observed that the application of HA, Zn, and amino acids, along with their interactions, particularly at higher levels has a significant influence on yield characteristics as grain yield, yield components, and the overall protein content of the wheat produced. Such results underscore the significance of utilizing these agricultural inputs effectively to enhance wheat production in Libya, thereby contributing to food security.
