A field experiment was carried out at Bahtim Agricultural Research Station Farm during 2010/2011 and 2011/2012 seasons. The experimental site is located at lat. 30.80, long 31.16 and 14.00 m above the mean sea level, to study the effect of farmyard manure (FYM) application rates (zero, 12 and 24 t/ha.) as well as phosphorus fertilizer at the rate of 15% P2O5 with three sources i.e. without, supper phosphate (15 % water soluble P2O5) and rock phosphate (6.25 %P2O5 as a total form) on yield and its some attributes as well as macronutrients uptake and protein percentage of wheat variety (Giza 168). The obtained results could be summarized as follows: 1- The highest significant values of grain, straw and biological yield as well as N, P, and K uptake of such yields, in addition protein % of wheat grain were recorded by adding FYM compared to without FYM addition in both seasons. 2- Generally, in most cases, supper phosphate gave the best significant values of all parameters under this study followed by the rock phosphate in both seasons. While, the lowest ones were observed without P source addition in both ones. 3- Maximum FYM rate, with supper phosphate significantly improved such parameters in the both seasons. Similar trend was recorded by the same rate of FYM with rock phosphate for most parameters under this study. On the contrary, the lowest ones were recorded without addition FYM and without P source in the both seasons. So, the phosphorus availability from either both P sources can be enhanced if it is mixed with farmyard manure. Since it increases availability and efficiency of P and enhances wheat yield and its quality.
