AbstractAn experiment was applied at the Field Crop research Station of State Board for agricultural Research during Autumn seasons of 2006 and 2007. To investigate the effects of tillering capacity in yield and its components in maize. Six genotypes are used in the study (Bahooth 106syn.,IPA 5012 syn., Rabe syn., Masera syn.,3003 tribal hybrid and A5xR5 single hybrid). RCBD design with four replications in factorial experiment was used. The results revealed that ears number per plant didn't affect by tillers or without in the first season, but in the second season genotypes without tillers gave higher ears number per plant (1.1) ears genotypes without tillers gave a higher values for grains number per row, number of rows per ear, grains and weight of 100 grains in two seasons. Grains yield.ha-1 was increased significantly at without tillers in two seasons (6.06 – 4.74)ton.ha-1 abut 27.57% and 36.99% for first and second season respectively. We can be conclude there were negative effect for tillers in yield and its components, also to increase maize productivity should be produce tillerless genotypes.
