Response of Three Maize (Zea mays L.) Varieties to Spraying with Pyridoxine

Abstract

A field experiment was carried out during the spring season of 2022 with the aim of determining the effects of spraying four concentrations of pyridoxine (0, 1500, 3000, 4500) mg/L on some growth characteristics and yield of three maize varieties (Al-Rabi’, Sarah, Baghdad3). The experiment was conducted at the research station of the College of Agriculture - University of Anbar using a randomized complete block design (RCBD) with three replications. The results of the study indicated a significant effect of pyridoxine on plant growth characteristics, and yield and its components. The concentration 4500 mg/L gave the highest average for leaf area, number of grains per ear, weight of 300 grains, and grains yield. The varieties differed significantly in most of the studied traits, as variety (Baghdad3) was distinguished by the shortest period of male and female flowering, the number of grains per ear, and the grain yield; while variety (Al-Rabi’) exceeded in the traits of leaf area and weight of 300 grains. The interaction between the varieties and the concentrations of pyridoxine also had a significant effect on most of the studied traits, as variety (Al-Rabi’) was superior in grain yield at concentration (4500 mg/L).
