| The experiment was carried out at two different locations Al-Gubba and Telkeef , to study the effects of three spaces between rows(60 , 70 , and 80 cm) and five genotypes of maize (Buhooth 106 , Bura , Sara , ADA523 and Veto), using split plots in randomized complete , block design with three replications . Data recorded on plant height , ear length , number of rows per ear , number of grains per ear , 300 grain weight and grain yield per plant . combined analysis of variance of characters data for both locations revealed that mean square of genotypes and their binary interactions with spaces between rows and triple interactions with spaces and locations was highly significant for all studied characters , and mean square due to spaces between rows was highly significant for all characters except number of rows per ear . The genotype Veto gave a highly significant results at the 80 cm distance between rows for most traits. While the genotype Bura Showed a high significant yield at the same distance between rows. |
