Abstract: Two field experiments were conducted at Abdel Menem Riyadh village, Al-Bostan, Beheira Governorate in two successive winter seasons of 2008/2009 and 2009/2010 to assess the effects of some organic sources viz. chicken manure (CM), farmyard manure (FYM) and organic wastes (OW)(at rate of0, 50 kg organic-N/fed) in combination with different levels of inorganic N fertilizer 60, 90 and120 kg N/fed on wheat yield and its components under sprinkler irrigation system prevailing in the region and to evaluate to what extent the fertilizer treatments impact on soil fertility status of the experimental field. The results showed that application of organic nitrogen sources in combination with inorganic nitrogen recorded significant effect on wheat grains and straw yields and weight of one-1000 grain. The significant effect of the organic nitrogen sources was in the following order: CM > FYM > OW with the exception of the significant effect of OW and FYM, which were similar on their effect on wheat straw yield. Applying CM (at rate of 50 kg organic-N/fed. =2ton CM/fed) combination with 90 kg N/fed significantly yielded the most significantly favorable N, P and K uptake in wheat grains and straw. When CM was applied at rate (50 kg organic nitrogen/fed.) in combination with 90 kg N/fed, the experimental soil gained after harvest the highest amounts of N, P and K as well as the highest amount of organic matter that will support the subsequent crop.
