| Abstract | ||
| Pots experiment was conducted in lath house at Dept ofSoil and Water Sciences. College of Agriculture - University of Baghdad. Treatments included three levels of agriculture sulfur (95% S) which were 0, 500 and 1000 kg S.ha-I, three levels of poultry manure 0, 20 and 40 tone. ha-' and three levels of rock phosphate (1O.22°/.,P ) which was 0, 80 and 160 kg P.ha-I. Bread Wheat seeds IPA99 were planted. Addition of agriculture sulfur showed a significant increase in availability of 1', N, K, and S04-2 with increasing level of addition up to level of 1000 kg S. ha-' reaching 14.04rng P.Kg-' , IS.811l1g N.Kg-'• 230.76mg K.Kg- 250.33mg. S04-2 Kg-I respectively .. The results showed that addition of organic fertilizcr significantly affect availability of P, N, K, and S04-2 with increasing addition levels up to 40 tou.ha' giving highest availability 13.88 mgP.Kg-1, 15.53111g N.Kg-'• 228.68111g K.Kg-1, and 228.51 mg. S04-2 Kg-I respectively .. Addition of rock phosphate increased significantly availability of P N, K, but not S04-2 .with increasing additir-n levels up to 160Kg P.ha-' giving highest availability 12.87mg PKg-', 13.51mg N.Kg-'• 227.18mg K.Kg-', respectively .Addition of rock phosphate, agriculture sulfur and organic fertilizer increased significantly all parameters or piant growrn anti Piant height, number of tillers, dry matter yield, grain yield, and percent 01' protein with increasing level of addition and highest mean for growth parameters was at level of 1000 kg.S. ha', 40 ton ha-' organic fertilizer, 160Kg P. ha', reached to 83clll, 26 branches, 74.6Ig.por', 27.8Ig.por' and 12.20% respectively. | ||
