Abstract:
Studies on Soil test Crop Response based Integrated Plant Nutrient Management System (STCR-IPNMS) were conducted for the desired yield targets of Pea, on alluvial soil of Agricultural Research Farm, Banaras Hindu University, Varanasi during rabi 2017. Testing of developed fertilizer prescription equation is necessary to demonstrate the effectiveness of technology delivery to the stake holders in need. To assess the validation of fertilizer prescription a series of experiment was setup in four locations of eastern plain zone of Utter Pradesh. Soils of the selected location are analyzed initially for available N, P and K. Treatments include control, farmer practices, general recommended dose of fertilizer and STCR based fertilizer dose for an yield target of 15 and 20 q ha-1 and STCR based fertilizer dose for an yield target of 17 and 22 q ha-1 with 2 t ha-1 FYM. 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, per cent increment in yield and benefit cost ratio (B:C) were worked out. The results of the experiments indicated that in all the four locations, the per cent achievement of the targeted yield was within±10% variation proving the validity of the equations for prescribing integrated fertilizer doses for pea. The highest per cent increment in yield was recorded in the yield target of 22 q ha-1 (49.13 per cent) followed by 17 q ha-1 (34.00 per cent) over farmer’s practice. The highest mean grain yield was recorded in STCR-IPNMS–22 q ha-1 (2175 kg ha-1). The highest benefit: cost ratio (7.92) was recorded in STCR-IPNMS 22 q ha-1 is followed by STCR-IPNMS 17 q ha-1 (6.78). The fertilizer prescription equations developed for pea under IPNMS can be recommended for alluvial Inceptisol of eastern Utter Pradesh for achieving a yield target of 22 q ha-1 with higher economic return.
