Abstract:
The field experiment was carried during the period of April to June 2016 at Horticulture
farm of Sher-e-Bangla Agricultural University Dhaka-1207, Bangladesh. The
experiment was laid out in the Randomized Complete Block Design with three
replications. Treatment consisted of four levels of plant growth regulator i.e. G
0
hormone, G
1
boron, B
1
= 50 mg/l, G

= 15 ppm, B
2
=100mg/l, G

=150mg/l; and three levels of boron i.e. B

= 30 ppm. Result revealed that the vegetative growth namely
plant height was highest (255.38 cm) in G
