A field experiment was conducted at Rice block in RARS Warangal, during Rabi-2015-16 and 2016-17 to study the rescheduling of fertilizer doses in Rice for Central Telangana. The results revealed that the non significantly higher grain yield and significantly, higher straw yields (6816 and 6187 kg/ha, respectively) were recorded by the application of nitrogen, phosphorus and potassium 150%-100%-100% (180-60-40kg/ha) recommended dose over the others. Significantly maximum N, P, K, Zn, Cu, Fe and Mn uptake 199 kg/ha, 25.69 kg/ha, 134 kg/ha, 341g/ha, 67g/ha, 3492g/ha, 1403g/ha, respectively were recorded by the application of nitrogen, phosphorus and potassium 150%-100%-100% (180-60-40 kg/ha) recommended dose, respectively over the others. The highest benefit cost ratio (1.84) and net income (45,236/-) was recorded by application of nitrogen, phosphorus and potassium 150%-100%-100% (180-60-40 kg/ha) alone and lowest benefit cost ratio (1.46) and net income 30,655/- was recorded by the application of nutrients based on current recommended dose of fertilizers along with vermicompost application @2 t/ha.
