Soil test crop response based fertilizer prescription on marigold grown on Mollisols of Uttarakhand, India

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 G.B. 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 i.e. 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 1.06, 0.34 and 1.32kg for nitrogen, phosphorus and potassium respectively. Contribution of nitrogen, phosphorus and potassium from soil for marigold was 26.23, 54.03 and 42.02. Contribution from fertilizer with FYM for marigold was 98.35, 40.25 and 168.68 Percent contribution of nutrient from fertilizer without FYM for marigold was 83.25, 38.96 and 168.91respectively. | Soil test crop response based fertilizer prescription on marigold grown on Mollisols of Uttarakhand, India
