Description
Summary:This study aimed to assess the performance and the effects of different surface irrigation systems, growth, and yield of maize crops in the irrigation district of Babil Iraq. Field experiments were conducted in the autumn of 2020 to manage five surfaces irrigation systems Besides, two irrigation intervals (5 and 8 days) and two levels of organic fertilizers (humic acid) (0 OM0 and 20 OM1 kg ha -1 ). The experiment was a Split Split Block Design with three replications. The results indicated that the actual water consumption use (ETa) varied with irrigation systems. ETa reached 688, 673 mm season -1 for BSI treatment and decreased to 293, 275 mm season -1 for APFIRB under irrigation intervals 5 days and OM0, OM1 treatments respectively. Organic fertilizer reduced the amount of ETa by 4 and 2.5% compared to control in 5 and 8 days irrigation intervals, respectively. The mean grain yield reached 7149.9 kg ha -1 for OM1, while organic humic acid application improved the grain yield by 7.95% compared to OM0. Meanwhile that the no significant differences in corn grain yield with irrigation systems.
