Abstract:
The experiment was carried out at the Farm of Sher-e-Bangla Agricultural University,
Dhaka-1207 to find out the effect of nitrogen and boron on growth and yield of BARI
Tomato-18 during the period of November 2019 to March 2020.The experiment
comprised with four level of nitrogen viz. 0, 80, 120, 160 kg/ha., and three levels of
boron viz. 0, 1.0, 1.5 kg/ha. The two factor experiment was set-up in Randomized
Complete Block Design (RCBD) with three replications. In total, there were 12
treatment combinations in this study. A unit plot size was (1.8 m × 1.25 m i.e. 2.25 m
)
and the treatment were distributed randomly in each block. Data on growth and yield
parameters were recorded and analyzed statistically. Results showed that individual
and combined effects of nitrogen (N) and boron (B) were significant in variation of all
growth and yield contributing characters. The highest plant height (137.67 cm), number
of flower clusters per plant (14.33), flowers per cluster (15.33), fruits per cluster (13.0),
fruits per plant (68.66), minimum required date for flowering (32.33 DAT), for fruiting
(40.33 DAT) and for harvesting (88.33 DAT), fruit weight per plant (3.1700 kg), fruit
weight per plot (18.45 kg), highest fruit yield (79.5 t/ha), highest fruit length (76.00
mm) and highest fruit diameter (44.333 mm) were recorded from the application of

treatment. On the other hand, the lowest yield of fruit (34.5 t/ha) and for all
cases lowest result were found in control treatment. There were no significant effect on
variation of N, P, K, S, pH, OC and OM concentration in post-harvest soil for the
application of N and B. The maximum N content (0.086 %), P (21.33 ppm), K (0.17
meq/100 g soil) S (25.667 ppm), OC (0.72 %), OM (1.24 %) concentration were
obtained at N

treatment. It can be said that the interaction of 120 kg/ha N + 1.0
kg/ha B i.e. N

treatment was best compared to others used in this experiment for
growth and yield of BARI Tomato -18.
