| Abstract | ||
| A field experiment was conducted during spring season 2015 in order to study the effect of irrigation and concentrations of ascorbic acid( ASA) yield and its components for two cultivars of Zea mays L. Split complete block design with three replications the main plots were irrigation treatment, the control treatment (irrigation 50% of the water available),75%,50% of the amount of control water treatment the subplots were a combination of ASA concentrations (0,100,200 ppm) and two cultivars (Fajer,5018). Irrigation treatment 75% of the treatment (control) gave the average length ear 18.54cm, rows number per ear 15.30 row.ear-1, grain number per row 26.84 kernel.row-1, grain number per ear 473.80 kernel.ear-1, grain yield 5.70 ton.ha-1 did not differ significantly from irrigation treatment (control) which started to give higher average rate of 19.08 cm and 15.54 row.ear-1 and 28.47 kernel.row-1 and 509.80 kernel.ear-1 and 5.64 ton.ha-1 respectively, while the irrigation treatment gave 50% of the treatment measurement lowest average for studied measurements. Outweigh the concentration of 200 ppm by increase the average row number per ear 15.57 row ear-1, grain number per row 27.69 kernel row-1 , grain number per ear 472.50 kernel ear-1, grain yield 5.39 ton.ha-1 . while 5018 gave the highest length ear, grain yield. The interference between irrigation treatments and ascorbic acid ASA was significant in grain yield. There was significant interaction between the three factors in the grain yield only. Therefore, we recommend possibility treatment of Zea may L. plant with ASA in concentrations 200 ppm to improve capacity of water stress, and recommend possibility of irrigation water by 75% of need of the full irrigation (50% depletion of available water) without significant effect on the yield and its components. | ||
