On the basis of soil test value of farmer field, fertilizer prescription equations are essential to demonstrate the effectiveness of technology delivery to the stake holders in need. The present study was conducted at Bhojpur to evaluate the model through field experiments in Eastern zone of Uttar-Pradesh. The treatments included control, general recommendation dose, farmer practice, soil test crop response STCR based fertilizer dose for an yield target of and t ha-1 . Based on the initial soil test values of available N, P and K and the quantities of N, P and K contributed through farm yard manure (FYM), fertilizer doses were calculated and applied for STCR and STCR-INM treatments for the respective yield targets. The treatments were imposed and cultivation practices were carried out periodically and the grain yield was recorded at harvest. | Validation of soil test and yield target based fertilizer prescription model for rice on inceptisol of eastern zone of Uttar Pradesh India
