| Abstract | ||
| This study was conducted to determine the effect of seed size ( small , medium , large and mixed ) and plant density ( 300 and 400 seeds/ m2 )in yield and yield components of three bread wheat varieties (Sham-6 , Iraq , and Iz ) .Seeds classified using standard sieves no.7and 8 (2.83 ,2.36 ml2 aperture) respectively .A field experiment was conducted in 2009-2010 in two locations, Alsharkat 126 km south Mosul and Ninava governorate using RCBD design . The results illustrate that the plants grown from large and medium seeds were superior in most yield and yield components traits in two locations except (spike wt. and seed wt. /spike gm). Iraq var. was superior in most yield traits in two locations comparing with the other two varieties , the second order interaction has a significant effect in some traits . This study illustrates that using large homogenized seeds and constant plant population were important factors to get good growth and increase chance to get more yield. | ||
