Abstract:
A field experiment was carried out in the Horticulture farm of Sher-e-Bangla
Agricultural University, Dhaka-1207, Bangladesh during the period of November
2016 to March 2017 The variety BARI Jhar Sheem 1 was used as test crop. Four
levels of nutrient sources viz. F
1
: 0 (Control), F
2
ii
: N
60
+P
20
+K
30
, F
3
: Vermicompost
(10 t ha
-1
) and F
4
: N
30
+P
10
+K
15
+ Vermicompost (5 t ha
-1
) and three levels of
irrigation frequency viz. I
1
= 3 days interval, I
2
= 6 days interval and I
3
= 9 days
interval were used for the present study. The experiment was laid out in
Randomized Complete Block Design with three replications. Different nutrient
sources treatment showed significant influence on most of the parameters and the
treatment. The highest yield ha
-1
(12.87 t) of French bean was obtained from F
4
and the lowest (9.05 t) was obtained from F
1
.
Considering different irrigation
frequency, the highest yield ha
-1
(12.07 t) of French bean was observed in I
2
and
the lowest (9.47 t) was obtained from I
3.
In terms of combined effect of nutrient
sources and irrigation frequency, all the studied parameters were influenced
significantly. The highest pod yield ha
-1
(15.19 t) was recorded from the treatment
combination of F
4
I
2
where the lowest (8.53 t) was recorded from the treatment
combination of F
1
I
3
. Therefore, Application of N
30
+P
10
+K
15
and Vermicompost (5
t ha
-1
) with Irrigation at 6 days interval was best for French bean production.
