Abstract:
An experiment was conducted during the period of April to June 2021 at Horticulture farm
of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh to evaluate the effect
of seed priming and different growth regulators on growth and yield of yard long bean. The
experiment was laid out in the Randomized Complete Block Design with three replications.
Treatment as four levels of seed priming treatments i.e. Control (P
0
), Hydro priming (P
1)
,
Halo priming 1% CaCl
2
(P
2
), Osmo priming 10% PEG (P
3
), and three levels of growth
regulators i.e. Control (G
0
), Application of NAA (G
1
), Application of Kinetin (G
2
), which
in combination made 12 treatment combinations. In case of effect of priming treatment P
3
showed the highest value of Germination percentage (74.1%), Shoot length of seedlings
(28.36cm), Root length of seedlings (9.98cm), Fresh weight of seedlings (5.38g), Dry
weight of seedlings (2.68g). Again, the days to first flowering was lowest in P
0
(41.3) and
highest in P
3
(47.2) treatment. In the case of effect of plant growth regulators in, treatment
G
1
showed the highest value of No of branch/plant (7.60), No of pods plant
(17.50), Pod
length (30.07cm), Individual pod weight (17.30g), Yield plant
-1
(4.75t/ha). But the days to
first flowering was lowest in G
0
(43.3) and highest in G
1
(45.3) treatment. Again the effect
of different combination between seed priming and plant growth regulators, treatment P
3
showed the highest value of No of branch/plant (9.42), No of pods plant
(32.33), Pod
length (38.44cm), Individual pod weight (22.25g), Yield plant
-1
(6.34t/ha) compared to
other treatment. The days to first flowering was lowest in P
0
G
0
-1
-1
(40.6) and highest in P
3
(49.3) treatment. So the combination of P
3
G
1
found the best for cultivate yard long bean.
