Deciphering the Potential of Bioactivated Rock Phosphate and Di-Ammonium Phosphate on Agronomic Performance, Nutritional Quality and Productivity of Wheat (Triticum aestivum L.)

Wheat is one of the leading staple crops in many countries. Phosphorus (P) plays an important role for wheat growth and yield as it takes part metabolic pathways. Even soluble phosphatic fertilizers, most Pakistani soils, being alkaline calcareous nature, show phosphorus use efficiency (PUE) not more than 10–25%. The major issue unavailability P due to fixation precipitation reactions with soil particles. Composting rock-phosphate animal poultry manures supplied bio-stimulated phosphate solubilizing bacteria (PSB) only enhances RP solubilization but also serves a potent source plants. Composted/bio-activated (B-RP), prepared by group three bacterial strains i.e., Pseudomonas sp. (E11), Bacillus (MN54) Enterobacter (MN17) aided molasses (5%) urea (10%), was tested alone various combinations di-ammonium (DAP). In this pot trial, combined application B-RP DAP found superior sole B-RP. combination sharing equal amount recommended showed better results compared DAP, giving improved shoot biomass (25%), total P-uptake (67%), recovery (75%), dry matter (29%), crude protein other yield, physiological nutritional quality parameters wheat. So, could be concluded that integrated proportion serve management practice improving quantity grain.
