Abstract:
The field experiment
was conducted at Sher-e-Bangla Agricultural IJniversity
Farm. Dhaka during the boro season from I November 2007 to 15 March 2008
to observe the performance of zinc and boron on the yield and yield
contributing characters of BRRI dhan29. The experiment consists of three
levels of zinc viz. 0. 2.5 and 5.0 kg ha
4 and three levels of boron viz. 0, I and 2
kg hi'. The experiment was laid out in factorial randomized complete block
design with three replications. Application of Zn significantly influenced all the
growth and yield contributing characters except plant height (cm), panicle
length (cm) and sterile spikelets panicle
4 whereas boron fertilization
significantly influenced all parameters except plant height (cm). panicle length
(cm) and 1000 grain weight. Five kg Zn hi' and two kg B hi' Zn

influenced plant to produce the highest grain yield. The maximum yield 5.56
thi' was recorded for this combination effect. Integrated use of zinc and boron
significantly influenced contents and uptake of zinc (Zn) and boron (B) in the
grain and straw of BRRI dhan29. In all eases of contents and uptakes of Zn and
B in both grain and straw as allècted by Zn and B fertilizations. Zn5

performed the highest results.
