It was found that a balanced application of NPK+FYM gave the highest values for the measured parameters and lowest at the control. Values were generally highest at tillering, followed by the flowering and dough stages. A significant positive interaction between fertilizer treatments and physiological stages of wheat growth was observed, being highest at maximum tillering due to application of NPK+FYM. Stepwise regressions have revealed that grain yield of wheat was significantly associated with mineralizable N at tillering (R(2)=0.80), MBC at flowering (R(2)=0.90) and alkaline phosphatase activity (R(2)=0.70) at dough stages of wheat growth.
