Effect of Mycorrhizae Inoculation and Spraying with Amino Acids on some Yield Traits and Leaf Proline Content of Corn Plant

Abstract

Abstract A field experiment was conducted in the spring season in the field of the College of Agriculture of the University of Babylon to study the effect of mycorrhizae inoculation and spraying with amino acids on some growth indicators of corn according to The Randomized Complete Block Design (RCBD) using three factors. The second factor is the amino acids with four levels (0, 200 proline, 200 arginine, (200 + 200) mixed mg liter (PPM) and the third factor is the use of two water stresses for water which is irrigation when draining (50-75)% of available water. The inoculation with mycorrhizae was significantly excelled by giving higher yields in grain yield 3.83 tons.ha-1, biological yield 11.30 tons.ha-1, the weight of 1000 grains (g) 96.08 g, proline 5.07 μmol g-1, 2-Spraying with amino acids at treatment A3 gave the highest values for all studied traits. The water stress treatment, which was designated W1, considerably outperformed its competitors by producing the highest values for growth markers from.
