Abstract: Two field experiments were conducted in the Experimental Farm of Sids Agricultural Research Station, ARC, Beni-Suef Governorate during the two successive seasons of 2016/2017 and 2017/2018 to study the affect of organic manure sources (compost and farmyard manure "FYM") and levels (0.0, 5.0 and 10 t/fed) as well as bio-fertilization( with and without) on wheat productivity in term of growth (plant height and dry weight), yield components (number of spikes/m2, number of grains/spike and 1000-grain wheat ), yields (grains and straw ) and N,P and K uptake as well as soil properties (pH, EC and organic matter % ) and soil fertility (available N, P and K) in soil after wheat harvest. The results reveal that compost had a slightly higher effect on wheat productivity and soil properties and its fertility than FYM. Increasing organic manure levels enhanced all studied growth, yield and yield components and N, P and K uptake in grains and/or straw, except 1000-grain weight which did not affect. Also, increasing manure levels improved all studied soil properties and fertility, except soil salinity which increased due to increasing manure levels. Bio-fertilization enhanced growth, yield and its component and nutrient uptake, except 1000-grain weight. All studied soil properties and fertility did not respond to bio-fertilization. Mixed bio-fertilizer with organic manure at a rate of 10 t/fed resulted in maximum wheat productivity and improved soil properties and fertility of soil after wheat harvest.
