A field experiment was carried out at Selmamer during the 2014 cropping season to determine the effects of cultivation frequency on growth, yield and yield components of bread wheat (Triticum aestivum L.). The treatments used in the study were seven cultivation frequencies (30 DAE, 45 DAE, 60 DAE, 30 and 45 DAE, 30 and 60 DAE, 45 and 60 DAE, 30, 45 and 60 DAE) and one control or no cultivation. The experimental design was a randomized complete block design (RCBD) with four replications. Phenological and growth parameters such as yield and yield components, total biomass and harvest index were studied. The result depicted that frequency of cultivation had brought no significant effect on the studied phenological parameters. The result also showed that all the studied growth parameters were significantly affected by frequency of cultivation except spike length. There was a proportional increased number of productive tillers per plant obtained from the cultivated treatment over the control (non cultivated) one. All the studied yield and yield components except harvest index were significantly affected by frequency of cultivation. Grain yield advantages of 62.72% and 57.84% were obtained from the treatments 30 and 45 DAE and 30 and 60 DAE (from cultivation frequency of 30 and 45 and 30 and 60 days after emergence), respectively over the non cultivated or the control one. The highest grain yields of (3.93 t ha^-1) and (3.475 t ha^-1) were recorded for the treatments 30 and 45 DAE and 30 and 60 DAE, respectively. Therefore, it can be concluded that using the cultivation frequency of  30 and 45 days after emergence or 30 and 60 days after emergence is advisable and could be appropriate for bread wheat  production in the test area even though further testing is required to put the recommendation on a strong basis.
