Response of Bread Wheat ( Triticum Aestivium L.) Yield and Yield Components to Different Level of Phosphorous in Gozamen District, East Gojjam

The field experiment was done during the cropping season of 2017 at Gozamin district, North western Ethiopia to see the influence of different rates phosphorous fertilizer on the yield and yield components of Bread wheat. The experiment was laid out by Randomized Complete Block Design (RCBD) design with three replications of six phosphorous rates (0, 23, 46, 69, 92 and 115 kg ha -1). Significant differences in plant height (cm), number of effective tillers per plant, number of kernels per spike, spike length (cm), grain yield (Q ha -1) and biological yield (Q ha -1) were observed by the application of different rates of phosphorus fertilizers. However, only Harvesting index (Q ha -1) was not significantly affected by different rates of phosphorus fertilizers. It is concluded that phosphorus application at the rate of 115 kg ha -1 is more conducive to achieve the maximum yield (94.47 Q ha -1) for the research area as compared to the other treatments
