Abstract:
A field experiment was conducted at the Agronomy field, Sher-e-Bangla
Agricultural University, Dhaka, during March to June, 2014 to study the
response of BARI Mung 6 under different planting density and foliar
application of IAA (Indole-3-Acetisc Acid). The experiment was consisted of
three spacings viz. i) 20cm x 10 cm (S
1
) ii) 30cm x 10 cm (S
) and iii) 40cm
x10cm (S
3
2
) and four levels of foliar spray with IAA application viz. i) Control
(A
1
) ii) Spraying IAA @ 50 ppm at 25 DAS (A
) iii) Spraying IAA @ 100 ppm
at 25 DAS (A
3
2
) and iv) Spraying IAA @ 150 ppm at 25 DAS (A
). The
experiment was laid out in randomized complete block design (RCBD)
(factorial) with three replications. The results showed that growth, flower and
pod dropping and biological yield of BARI Mung 6 significantly responded to
the different levels of IAA application, plant density and their interaction
effects. Significant effect of plant density was found on growth and biological
yield. The plant with 30 cm x 10 cm spacing gave the highest biological yield
ha
-1
(5.41 t), stover yield ha
-1
(0.884 t). Flower and pod dropping plant
was
minimum (17.95) in S
Foliar application of IAA also had significant effect on
different growth, flower and pod dropping and biological yield. The highest
stover yield ha
-1
1.
(0.91 t), biological yield ha
-1
(5.33 t) and harvest index
(40.33%) were observed from 100 ppm of IAA application. However, the
lowest flower and pod dropping plant
-1
(16.99) was observed in 150 ppm IAA
application. The combination effect of 100 ppm IAA application and 30 cm
row to row distance showed maximum biological yield ha
-1
(5.38 t) and 100
ppm IAA with 20 cm row to row distance gave lowest flower and pod dropping
plant
-1
(16.28)
