Abstract

Field experiment was carried out during two autumn seasons of 2013 and 2014 in Ramadi City/AL-Anbar province (first season experiment was applied in field at north of Ramadi and the second season experiment was applied in field at east of Ramadi) on corn plant (Zea mays) cv. 5018. Factorial experiment used according to RCBD design under split plot arrangement with three replicates. The experiment included studying effects of two factors: zinc foliar nutrition at concentrations 0, 40 and 80 mg.l-1 and irrigation periods at 5, 7 and 9 days and their interaction on growth and yield characters of corn plant. Results showed a significant effect of zinc concentration Zn2 (80mg. l-1) in traits of plant height, leaf area, average of grain number per cob, weight of 1000 grain and grains yield, of 227.44 and 219.33 cm, 6031 and 5170 cm2, 736.5 and 750.2 grain.cob-1, 239.87 and 218.06 g, 12.08 and 10.84 ton . ha-1,for each season, respectively. Furthermore, 5 days irrigation was most effective in above traits of 214.44 and 207.89 cm, 5196 and 4745 cm2 , 709.9 and 669.2 grain.cob-1, 219.59 and 207.39 g, 10.75 and 9.58 ton.ha-1. The results indicated that the interaction between Zn2 concentration (80mg.l-1) and 5 days irrigation was more effective in increasing studied growth and yield traits.
