Abstract
The
experiment was conducted at the Horticultural farm of Sher-e-Bangla
Agricultural University, Sher-e-Bangla Nagar, Dhaka, during the period from
April, 2009 to March, 2010 to investigate the effect of potassium levels on
growth, flowering and bulb yield of tuberose. The experiment consisted of four
levels of potassium i.e. K0: 0, K1: 170, K2:
180 and K3: 190 kg K2O ha-1. Results showed
that potash application significantly increased the number of leaves plant-1,
leaf length, leaf breath, number of side shoots plant-1; and bulb
and flower attributes. Significantly the highest flower (16.4 t ha-1)
and bulb (22.0 t ha-1) yields were noted in K3 whereas the lowest flower (11.5 t
ha-1) and bulb (17.2 t ha-1) yields were recorded in K0.
Key words: Fertilizer,
K2O and Polianthes tuberose.
