Fertiliser use play a key role to mitigate nutrient mining in soil and therefore, usage of fertiliser inputs should be based on crop response to applied nutrients for various soil types. At this moment, Soil Test Crop Response based Integrated Plant Nutrition System (STCR-IPNS) has got a predominant role in managing demand driven nutrient supply to crops for enhanced yield, Fertiliser use efficiency and profitability to farmers. With this scope ahead, present study has been undertaken with hybrid brinjal (Solanum melongena L.), a member of Solanaceae family, the most common vegetable cultivated in Andhra Pradesh, with a view to establish relationship between soil test values and crop response to applied fertilisers, to developing Soil Test Crop Response based Fertiliser Prescription Equations (FPEs) under Integrated Plant Nutrition System (STCR-IPNS) by targeted yield model, to assess fertiliser input saving due to IPNS. Regardless of the fertility strips, response to fertiliser N, P2O5 and K2O was increased gradually in test crop experiment up to highest level i.e. 240:120:180 kg ha-1 , correspondingly and to FYM@ 25 t ha-1 ; initial soil fertility and IPNS also had profound influence on yield and uptake by hybrid brinjal. Results revealed that a quintal of hybrid brinjal fruit requires 0.36 kg N, 0.14 kg P2O5 and 0.35 kg K2O following the order of N>K2O>P2O5. Contribution of nutrients from FYM was 25.51, 15.25 and 27.03 per cent for N, P2O5 and K2O.
