Abstract: The pot culture experiment was conducted to assess the ‘Effect of phytase and phosphorus levels on soil phosphatase activity and nutrient availability in an Inceptisol under fodder maize’ cultivation during kharif season, 2016-17 at Department of Soil Science and Agricultural Chemistry, Mahatma Phule Krishi Vidyapeeth, Rahuri. The treatment consisted four levels of phytase (1200, 2400, 3600 and 4800 IU) and phosphorus (0, 25, 50 and 75 kg P2O5 ha-1) with absolute control. Enzyme activity and nutrient availability in soil was assessed at 30 days after sowing and at harvest of fodder maize. It was observed that, application of phytase @ 4800 IU and 0 kg P2O5 ha-1 recorded significantly higher acid (14.74 and 15.83 µg PNP g-1 soil hr-1) and alkaline phosphatase activity (27.81 and 29.09 µg PNP g-1 soil hr-1, respectively) at 30 days after sowing then declined at harvest of fodder maize. The application of phytase @ 4800 IU and 75 kg P2O5 ha-1 recorded significantly higher available nitrogen (103.08 and 106.40 mg kg-1), phosphorus (11.35 and 11.67 mg kg-1) and potassium (185.63 and 186.50 mg kg-1, respectively) at 30 days after sowing then declined at harvest. In general, the application of phytase @ 4800 IU and 00 kg P2O5 ha-1 significantly increased enzyme activity at 30 days after sowing then declined at harvest as well as significantly increased the available nutrient status at 30 days after sowing then declined at harvest by the application of phytase @ 4800 IU and 75 kg P2O5 ha-1. This study suggests that, application of phytase and phosphorus increasing the enzyme activity as well as nutrient availability in soil 30 days after sowing and at harvest as compared to the initial status.
