Suspension P biofertilizer made from sewage sludge ash and enriched with Bacillus megaterium was compared in field expts. on spring wheat to superphosphate and phosphorite. Three levels of P2O5 (40, 60 and 80 kg/ha) and 2 levels of plant protection (without protection, full plant protection) were used. The effects of biofertilizer on plant d. after sprouting, general and productive tillering, stem length, the no. of plant leaves, leaf dimensions, ear length and mass of grain from ear were studied. The new biofertilizer was as active as the com. ones. Full chem. protection improved morphol. attributes of the plants.
