Requirement of nitrogen, phosphorus and potassium fertilizers for wheat cultivation under irrigation by municipal wastewater

This study quantified the optimum doses of nitrogen (N), phosphorus (P) and potassium (K) fertilizers for wheat (Triticum aestivum L. cv Shatabdi) cultivation under irrigation by municipal wastewater (here after called wastewater). Separate experiments were conducted with the three nutrients, applyi...
