Tuberose responds well to the application of organic and inorganic manures. Apart from FYM (20
Tonnes/ha), a fertilizer dose of 100 kg N, 50 kg P2O5 and 70 kg K2O per hectare is recommended for tuberose production. For achieving increased essential oil content in flowers and for the maximum recovery of concrete, a fertilizer dose of 80 kg N 60 kg P2O5 and 40 kg K2O per hectare has been recommended. Of the full recommended dose of fertilizers, half the N, the full dose of P and K has to be applied at the time of planting and the remaining half of N is given as a top-dressing after 45 days of planting
Apart from N, P and K, calcium, magnesium, sulphur, iron, zinc, manganese, aluminium, boron and copper have also been found to influence the growth and flowering in tuberoses. Foliar spray of ZnSO4 0.5% + FeSO4 0.2% + Boric acid 0.1% improves growth and flowering.
Use of Growth regulators
Foliar application of GA3 at 50 to 100 ppm thrice at 40, 55 and 60 days after planting is found to be beneficial. The application of CCC at 5000 ppm and GA3 at 1000 ppm induces early flowering, increased flower stalk production and improves the quality of flowers.
Water and Irrigation Management
It is essential to irrigate before planting to provide optimum moisture for sprouting and further irrigation should be avoided until the bulbs are sprouted. Subsequent irrigation to the crop is given, depending on the prevailing weather conditions. In the summer months, irrigation is recommended twice a week and during winter at 10 days interval.
