Abstract
The
study was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural
University, Dhaka during the period from May 2010 to February, 2011. The
experiment consisted of five types of nutrient sources (F0, Control;
F1, cowdung 5 t + 260 kg Urea
+ 200 kg TSP + 200 kg MOP ha-1, F2, poultry
litter 3 t + 260 kg Urea + 200 kg TSP + 200 kg MOP ha-1, F3; cowdung: 10 t ha-1 and F4,
poultry litter: 6 t ha-1). The experiment was laid
out in a Randomized Complete Block Design (RCBD) with three replications. The
highest length of flower stalk (66.0 cm) and rachis length (35.11 cm) were
observed from F1 while the lowest was found from F0. The
highest number of spike (353530 ha-1) was observed from F1, while the
lowest (2,97,300 ha-1)
was found from F0. Highest yield of bulb (25.59 t ha-1) was recorded from F1, while the
lowest (17.33 t ha-1)
recorded from F0.
Keywords: Tuberose, organic and
