EFFECT OF FOLIAR SPRAY WITH ASCORBIC ACID ON TWO MAIZE CULTIVARS GROWN UNDER SALINE SOIL

Field experiment was conducted to investigate the impact of different concentrations of ascorbic acid (0,2, 4, 6, 8 g/l) on some growth characteristics, grain yield and of two maize cultivars (Furat, Buhooth-106) at the farm of field crops department, Agriculture College, University of Basrah, Iraq, during Autumn season 2019. The experimental design was split-split plots using Randomized complete block design (RCBD) with three replicates. Where ascorbic acid treatments placed in the main plots, while the sub plots includes the cultivars. Furat genotype gave the highest yield of 144.25 g/m(2). Spraying ascorbic acid at the concentration of 8 g/l produced maximum yield of 173.89 g/m(2). Minimum grain yield was found in control treatment (106.60 g/m(2)). Furat genotype spraying with high concentration of ascorbic acid 8 g/l was superior with 191.97 g/m(2) compared to all interactions.
