Abstract

A research work was carried out to find out the effect of planting depths and potassium levels on Tuberose (Polianthes tuberosa). The corms of tuberose were planted at a depth of 5, 10, and 15 cm and were fertilized with four levels of potassium 0, 50, 100 and 150 Kg of K2O ha-1 using K2SO4 as a source of K2O. Result of the study revealed that planting depth of 15 cm significantly affect days to first and last florets opening and increased length of spike, number of florets spike-1, and plant height. Planting depth of 5cm causes decreased number of days to last floret opening. Potassium level of 150 kg of K2O ha-1increase spike length, number of florets spike-1 and plant height. Planting depth of 15 cm and fertilizer application of 150 kg of K2O ha-1proved to be superior regarding spike length, number of florets and plant height, number of florets spike-1 and plant height. Hence planting tuberose at a depth of 15cm and fertilizer application of 150 kg of K2O ha-1 is recommended for commercial cultivation of tuberose.
