| Abstract : A field experiment was carried out at Alfandea, Babil during autumn 2013 and spring 2014 season to find out the response of some genotypes of Zea mays L,for agriculture distances and stages of foliar spray with Prosol to achieve highest grain yield. randomized complete block design according to the split-split plots arrangement with three replicates. The main plots included spray stage (non spray, 4, 8, 12 leaves), sub-plots included sowing space (65 and 75 cm) and sub-sub plots included genotypes (Abkarov-1 and Artnear). The results showed superiority of spraying phase at 4 leaves with characteristics (number of rows per ear, number of grains per ear and total grain yield), sowing space (65 cm) superior with total grain yield despite the superiority of sowing space (75 cm) with characteristics of yield components, and Artenear cultivar superior with character of total grains yield during autumn and spring season. The tri-interaction (spray stage 4 leaf x space 65 cm x cultivar Artenear) was superiored with total grain yield during autumn and spring season. There were a positive significant correlation between total grains yield and the yield components yield under studied. Keywords: Genotypes, Zea mays, distances, foliar spray, and Prosol . | ||
