Abstract:
The field and laboratory experiments were conducted at Horticultural farm of Sher-e-Bangia
Agricultural University. Dhaka during the period trorn October 2005 to February 2006 to study the
effect of phosphorus on growth, yield and shelf lite of broccoli cultivars. Four levels of
phosphorus fertilizers viz. Po=O kg Plha, P, = 30 kg Plha, P2 = 40 kg Plha and PJ =50 kg Plha were
used in the field experiment. The tield experiment was laid out in Randomized Complete Block
Design with three replications. Considering the yield and yield atributes of broccoli the highest
plant height (55.85 ern), stem diameter (5.69 cm), number of leaves (13.78), leaf length (45.97 ern)
at 60 DAT, shoot length (39.93 ern), root length (30.8Icm), fresh shoot weight (793.9 g), fresh
root weight (83.42 g) and main curd weight (264.3 g) and curd yield (13.81 tlha) were recorded
from P,. But the highest curd diameter (17.44 em), number of secondary curd (4.25). weight of
secondary curd (155.3 g) was found in P,. The laboratory experiment was laid out in two factors
Completely Randomized Design with four levels of phosphorus fertilizers viz. Po=0 kg Plha, P, =
30 kg Plha, P, = 40 kg Plha and P, =50 kg Plha and three storage conditions. The storage
conditions were as follows: i. stored in open condition at room temperature (24°('), ii. stored in
perforated polythene bags at room temperature (24°C) and iii. stored in perforated polythene bags
at 4°(' in refrigerator. The maximum shelf life of broccoli in open at room temperature (2.62),
polyethylene bag at room temperature (6.02) and polyethylene bag at refrigerator (17.0 I) were
found in Po.
