| Abstract | ||
| A field trial was conducted at the Experimental farm,College of Agriculture. Abu Ghraib, Baghdad , Iraq in two winter seasons ( 2001-2002 and 2003-2004) .The objectives were to investigate the effect of row spacing on the performance of some different bread wheat varieties on some growth characters and yield . Row spacing (15, 18 and 21) cm were assigned in the main plots and the varieties (Tahadi, Ipa99 , Ipa95 and Abu-ghraib-3 ) in sub plots . The results showed that significant effect from the 15 cm between rows, in flag leaf area in the first season ( 52.85 cm2) , number of spike / m2 in both season (406.25 and 474.83 ) respectively , biological yield 18.20 t/ha and in harvest index 0.32 in the second season. Abu-ghraib -3 cu . gave higher means in plant height and number of grain / spike in both season ( 95 and 97 cm) and (51 and 52) respectively, but Tahadi was superior in flag leaf area and it's chlorophyll concentration in both seasons (54.37 and 55.74 cm2 ) and (49and 50 mg/cm2 ) respectively and gave higher weight 1000 grains a nd increased grain yield in secon d season by 12.62%, this increase had getten from high leaf area and it's concentration of chlorophyll because that increas photothensis prodection.A significant interaction between two studied factors in flag leaf area and spikes/m2 and then with grain yield .Asignificant positive correlation was found between grain yield and more of studied characters | ||
