Field experiments were conducted during the year 2013-14and 2014-15 in an Aquic Hapludoll at D7 block of Norman E. Borlouge Crop Research Centre of . Pant University of Agriculture and Technology, Pantnagar (290 N latitude and 79029’ E longitude). To fulfill the objectives of the present investigation two experiments were conducted in the year 2013-14 and 2014-15. In first phase fodder Sorghum (var. Pant Chari-7) was taken as an exhaust crop and in second phase . next season test crop Marigold (var. Pusa Narangi) was grown by dividing each strip in 24 plots having 21 treatments and 3 controlled plots. Response to selected combinations of three levels of FYM (0, 5 and 10 t ha-1 ), four levels of nitrogen (0, 60, 120 and 180 kg ha-1 ), four levels of Phosphorus (0, 30, 60 and 90 kgP2O5 ha-1) and four levels of potassium (0, 30, 60 and 90 kg K2O ha-1 ) for Marigold. The nutrient requirement for production of one quintal flower yield was , and for nitrogen, phosphorus and potassium respectively. Contribution of nitrogen, phosphorus and potassium from soil for marigold was , and . Contribution from fertilizer with FYM for marigold was , and Percent contribution of nutrient from fertilizer without FYM for marigold was , and . | Soil test crop response based fertilizer prescription on marigold grown on Mollisols of Uttarakhand, India
