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

Horticulture has emerged as an indispensable part of agriculture, offering a wide range of choices to the farmers for crop diversification
Studies were conducted by adopting the Inductive cum Targeted yield model so as to develop Soil Test Crop Response based Integrated Plant Nutrition System (STCR – IPNS) equations on a Udic Haplustalf of Tamil Nadu
The chrysanthemum flower yield ranged from 11.16 t ha-1 in absolute control of strip I to 21.01 t ha-1 in N240P150K75+FYM @ 12.5 t ha-1 of strip III
Summary
Horticulture has emerged as an indispensable part of agriculture, offering a wide range of choices to the farmers for crop diversification. It provides ample opportunities for sustaining large number of agro-industries which generate substantial employment. India has a reputation throughout the world as a soft power and ‘flower power’ is blooming, as the country emerges as the second largest producer of flowers around the world, next to China. Floriculture is an age old farming activity in India having immense potential for generating self-employment among small and marginal farmers. In the recent years it has emerged as a profitable agri-business in India and worldwide. The annual domestic demand for the flowers is growing at a rate of over 25%
