Abstract:
The present piece of work was conducted at the research field, Sher-e-Bangla
Agricultural University, Dhaka from March, 2017 to June, 2017 to find out the
effect of various seed priming treatments for seed germination, seedling vigor
and pod yield of yard long bean. The experiment consists of thirteen treatments
viz. T
0
= No priming, T
1
= Hydro priming at 12 hrs, T
= Hydro priming at 18
hrs, T
3
= Hydro priming at 24 hrs, T

= Hydro priming at 30 hrs, T

= Halo priming (1% CaCl

) at 12 hrs, T
6
= Halo priming (1% CaCl
) at 18
hrs, T
7
= Halo priming (1% CaCl

) at 24 hrs, T
8
= Halo priming (1% CaCl
) at
30 hrs, T
9
= Halo priming (2% KNO

) at 12 hrs, T
= Halo priming (2%

) at 18 hrs, T
11
= Halo priming (2% KNO

10
) at 24 hrs, T
= Halo priming
(2%KNO

12
) at 30 hrs. The experiment was laid out in randomized complete
block design (RCBD) with three replications. The result showed that seed
priming had significant influence on germination percentage, speed of
germination, vigor index, fresh weight of seedling, dry weight of seedling,
number of branches plant
-1
, first flowering of plant, number of pods plant
, pod
weight, , yield plant
-1
and weight of 100 seeds. In case of seedling growth and
yield parameter treatment T
5
(Halo priming 1% CaCl
at 12 hrs ) showed the
highest value of germination percentage, speed of germination, vigor index,
and fresh weight of seedling, number of pods plant

weight of 100 seeds (86.66%, 6.76, 1833.80, 1.43g, 73.67, 24.93 g, 1500.80g
and 16.37g), but T
(No priming ) showed the lowest value (36.66%, 1.18,
651.53, 0.31g, 16, 10.93g, 310g and 8.53g respectively). There had no
significant effect of seed priming on root length, shoot length, seedling length
and pod length of yard long bean. From this experiment it was clearly observed
that seed priming played an important role in the field performance of yard
long bean (BARI-Borboti 1). Actually treatment T
0
12 hrs) showed better field performance.
