A field experiment as per the technical programme of All India Coordinated Research Project on Soil Test Crop Response Correlation was conducted at N. E. Boroloug Crop Research Centre of the G. B. Pant University of Agriculture {\&} Technology Pantnagar (29 degrees N latitude and 79 degrees 29' E longitude) to study the effect of N, P and K fertilizers along with FYM to develop soil test based fertilizer recommendation equations for efficient and balanced fertilization for Menthol mint grown on Mollisol. The response of Menthol mint (var. Kosi) to selected combinations of three levels of FYM (0, 10 and 20 t ha-1), four levels of nitrogen (0, 50, 100 and 150 kg ha-1), four levels of phosphorus (0, 25, 50 and 75 kg P2O5 ha-1) and four levels of potassium (0, 25, 50 and 75 kg K2O ha-1) with simultaneous variations in initial available forms of these nutrients was studied. In the present investigation yield predictability coefficient (R2 0.932**) with soil, applied nutrients and their interaction was found highly significant. The basic data, i.e. nutrient requirement, soil efficiency, fertilizer efficiency and organic manure efficiency (N, P and K) were obtained with the help of soil test value, yield and plant uptake. Fertilizer adjustment equations were developed from the basic data. On the basis of these equations Ready Reckoner were also prepared at different yield targets and soil test values. Findings from present study can successfully be utilized for the larger parts of Tarai region of Uttarakhand as effective guide for efficient and balanced fertilizer recommendation.
