Abstract
In order to determine the suitable interspace of planting for two new Bread wheat cultivars (Triticum aestivum L.)under kerbala government environment.An experiment was laid out during the growing season of 2005 / 2006 at Husaniah / college of Agriculture. Five spacing with control were used ( in rows , 10 cm , 15 cm , 20 cm , 25 cm , 30 cm , apart and Broadcast ) to investigate their effect on growth , yield and its components of two cultivars IPA 95 and Al-Ftah ).Results showed that cultivars and the method of planting gave a significant effect on the most studied traits .Al-Fatah was superior compared with IPA 95 , whilst there was no significant differences between the two cultivars on spikes /m2 and yield . with interspace of planting and excluding spike length , no. of seeds / spike , the sowing in narrow rows (10-15cm ) gave the best results , where the planting in 10 cm between rows gave a yield of 4.44 ton /ha compared with 1.78 ton /ha for broadcast . The interaction effect was significant on plant height , leaf area index and no . of tillers / m2 where there was no effect on spike / m2 , no. of seeds / spike , no. of spikelet / spike and grain yield .There was no significant effect of the cultivars and interspace of planting and their interaction on no. of spikelet / spike and 1000 grain . It could be concluded that planting in narrow rows with new cultivars would be increase the productivity
