| Abstract | ||
| Biological experiment was conducted in the clay and sandy soils to study the effect of inorganic, organic and bio fertilization on growth and yield components as well as N, P and K- uptake by wheat plants. Ammonium sulphate (N) was added at the rates of 25 [50% the recommended dose (RD)] and 50 (100% RD) mg N kg-1 soil, while ordinary superphosphate (P1) and rock phosphate (P2) were applied at the rates of 9.72 (50% RD) and 19.44 (100% RD mg P kg-1 soil. Potassium sulphate (K1) and feldspar (K2) were added at the rates of 20.8 (50% RD) and 41.5 (100% RD) mg K kg-1 soil. The organic materials i.e. clover straw (CS), sunflower seed teflon (ST) and banana peel (BP) were added at a rate of (0.5%). Some wheat grains were inoculated by biofertilizers i.e. nitrobein (nit), phosphate dissolving bacteria (PDB) and potassiumage (Pot). The results showed that the treatments of [50% RD (NP1K1) + CS + ST + BP + Nit + PDB + Pot] gave the greatest values of the straw and grains dry weight, biological yield and harvest index, N-uptake by grains and P- and K- uptake by straw and grains if compared to the other treatments in both soils under study. Wherease the highest 1000 grains weight was observed with the treatment of [50% RD (NP2K2) + CS + ST + BP + Nit + PDB + Pot] in the clayey soil and [50% RD (NP1K1) + CS + ST + BP] in the sandy soil compared to the other treatments. The greatest values of N- uptake by straw were recorded with treatments of [50% RD (NP1K1) + CS + ST + BP] in the clayey soil and [50% RD (NP1K1) + CS + ST + BP + Nit + PDB + Pot] in the sandy soil compared to the other treatments. Finally, it could be concluded that the use of 50% of the recommend dose of the most mineral fertilizers (NP1K1) mixed with organic materials (CS + ST + BP) and biofertilizers (Nit + PDB + Pot) may reduce the mineral fertilization (NP1K1) dose, production cost and environmental contamination. | ||
