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 4.5 and 5.0 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. Using the data on grain yield and fertilizer doses applied, benefit: cost ratio was worked out. The results of the experiments indicated that in the entire three farmer’s field, the per cent achievement of the targeted yield was within ±5% variation proving the validity of the equations for prescribing integrated fertilizer doses for rice. The highest mean per cent achievement was recorded in the yield target of 4.5 t ha-1 (99.96 %) followed by T5 (yield target of 5.0 t ha-1) (98.36 %). The highest mean average yield was recorded in T5 STCR-NPK+FYM 5.0 t ha-1 (4918 kg ha-1) recording an increase of 30.93% over farmer’s practice. The highest benefit: cost ratio (3.32) was also recorded in STCR-INM (T5). The post-harvest soil available N, P and K indicated the build up and maintenance of soil fertility due to validation of soil test and yield target based fertilizer recommendation under STCR-INM. The fertilizer prescription equations developed for rice under STCR-INM can be recommended for Alluvial soil of Pratapgarh, Uttar-Pradesh (Inceptisol) for achieving a yield target of 4.5 and 5.0 t ha-1 with sustained soil fertility and it can be extrapolated to other agro-climatic zones of Uttar Pradesh on similar and allied soil types.
