Abstract:
A field experiment was conducted at the Agronomy research field, Sher-e-Bangla
Agricultural University, Dhaka, during the period from November, 2016 to April,
2017 to study the influence of supplementary foliar spray of urea and boron on the
growth and yield of chickpea varieties. The experiment was carried out in split plot
design considering two varieties i.e. BARI Chola-5 and BARI Chola-8 in the main
plot and five levels of supplementary foliar spray viz. T
= Recommended fertilizer
(RF), T

1
= RF + Foliar spray (FS) of water at flower initiation (FI), T
= RF + Urea
(2%) FS at FI, T

= RF + Boron (1%) FS at FI, T
= RF + Urea (2%) + Boron (1%)
FS at FI in the sub plot replicated three times. Variety

BARI Chola-8 (V
) gave the
highest above ground dry matter plant
-1
(11.95 g), pods plant
-1
(26.11), 1000 seed
weight (273.87 g) and seed yield (1.47 t ha

). In the case of supplementary foliar
spray, highest above ground dry matter plant
-1
(12.82 g), pods plant
(28.27), seeds
pod
-1
(1.92), 1000 seed weight (220.90 g) and seed yield (1.69 t ha
-1
) was produced by
T
treatment (RF + 2% Urea FS at FI). Regarding combined effects, the highest pods
plant

-1
(29.17), 1000 seed weight (298 g) and seed yield (1.75 t ha
-1
) were observed
from V

(BARI Chola-8 along with RF + Urea (2%) FS at FI) when V
(BARI
Chola-5 along with RF + Urea (2%) FS at FI) was significantly at par for pods plant
and seed yield. So, BARI Chola-8 or BARI Chola-5 cultivation with recommended
fertilizer plus additional 2% urea spray at flower initiation may be a way of
maximizing yield of chickpea.
