abstract
A field experiment was carried out at CSIR-Central Institute of Medicinal and Aromatic Plant Research Centre Purara, Bageshwar, India during 2016-2017. The study was carried out for “Effect of NPK levels on growth and yield of turmeric (Curcuma longa L.) under the Katyur valley of western Himalayan region of Uttarakhand”. The experiment was tested in RBD under different doses of NPK with three replications. Doses of nitrogen, phosphorus and potassium viz., To (Control, no fertilizer), T1 (30:30:60 NPK Kg/ha), T2 (60:60:120 NPK Kg/ha), T3 (90:90:180 NPK Kg/ha), T4 (120:60:120 NPK Kg/ha) and T5 (140:80:180 NPK Kg/ha) were applied and data was collected from the randomly selected plants of turmeric from each plot. Results indicated that higher fresh yield (28.17 t/ha), dry yield (6.6 t/ha) and dry recovery % (23.42) were significant with T4 (120:60:120 NPK Kg/ha) followed by T5. The growth parameters were significantly higher with the T4. In data the highest net return (INR 168200/ ha) and B: C ratio (1.72) was obtained under T4 followed by T5. It is clearly indicated that a nutrient level of 120:60:120 kg NPK/ha is optimum for growth and yield of the crop in the Katyur valley of western Himalayan region of Uttarakhand.
