Abstract


Field experiments were conducted during 2017 – 2018 to develop fertiliserprescriptions equations (FPEs) through IPNS for the desired yield targets ofChrysanthemum on Udic Haplustalf . The fertilisers prescription equations(FPEs) were developed under NPK alone and under IPNS for the desiredyield target of Chrysanthemum by using the basic parameters. The variationobserved in the achievement of targets was within the range of ± 10 per cent(90 – 110%) proving the validity of FPEs. Hence, the Inductive cum Targetedyield approach applied to develop fertiliser equations provides a strong basisfor maintenance of soil fertility with high productivity and efficient nutrientmanagement in “Precision Farming” for sustainable and enduring Agriculture
