PAUL, SANCHITA
A field experiment was conducted for evaluating the effect of irrigation and boron
splitting as foliar spray on growth and yield of lentil at the research field of the
Department of Agronomy, Sher-e- Bangla Agricultural University, Dhaka from
November, 2018 to March, 2019. The experiment consisted of three levels of irrigation
viz., I
0
: Control, I
1
: one irrigation at 25 days after sowing (DAS), I
: two irrigations at 25
DAS and 40 DAS and boron was applied by four levels viz., B
2
0
:
Control, B
: 80%
recommended dose as basal + rest 20% as foliar spray (FS) at pre flowering (PF), B
:
60% RD as basal + rest 40% as FS at PF, B
: 40% RD as basal + rest 60% as FS at PF.
The experiment was full set up in a split-plot design with three replications. Data
recorded on the basis of plant length, leaves plant

, 1000-seed weight, pod length, seed yield, stover yield and
biological yield were found statistically variable with treatments. In case of irrigation
result revealed that the highest dry weight plant
-1
(4.44 g), 1000-seed weight (24.26 g)
and seed yield (570.56 kg ha
-1
) were obtained from I
(Irrigations at 25 and 40 DAS). On
the other hand, the highest dry weight plant
-1
2
(4.40 g), 1000-seed weight (22.87g) and
seed yield (598.81 kg ha
-1
) were recorded from B
(40% RD as basal + rest 60% as FS at
PF). Result also showed that most of the treatment combinations gave the statistical
similar results in case of seed yield where numerically the highest seed yield (638.23 kg
ha
-1
) was recorded in I

B

. Numerically the highest stover yield (751.26 kg ha
) and
biological yield (1389.4 kg ha
-1
) was recorded from I
2
B
combinations. The combined use
of irrigation and boron was preferable than their individual application. It may be
concluded that I
0
B
3
3
combinations may be suitable for lentil cultivation if the crop
received at least 12.8 mm rainfall during its maximum vegetative stage.
Key words: Boron, irrigation, yield characteristics, lentil, foliar application, splitting etc.
