Abstract:
A pot experiment was conducted at the net house of the Department of Agronomy, Sher-eBangla
Agricultural University, Dhaka during the period from April to June 2018 to
investigate the yield performance and seed quality of mungbean as influenced by residual
effect of organic fertilizers and different doses of chemical fertilizers. The experiment was
laid out in two factors following a Factorial Experiment using Completely Randomized
Design (CRD Factorial) with three replications. Factor A. Organic fertilizer-3; viz.
O
0
=Control, O
1
=Cowdung, O
=Vermicompost and Factor B: Chemical fertilizers-4; viz.
F
0
=Control, F
1
2
=50% of recommended dose of chemical fertilizers, F
=75% of recommended
dose of chemical fertilizers, F
3
ii
2
=Recommended dose of chemical fertilizers. The result
revealed that the residual effect of vermicompost (O
) showed its superiority by producing
the highest mungbean yield (2.03 tha
1
-1
(12.69 g), pod length (8.65 cm), pods plant
2
) with higher plant height (40.13 cm), dry weight plant
-1
(33.70), seeds pod
-1
(12.24) and weight of
1000 seed (40.28 g) in this treatment. On the other hand, recommended dose of chemical
fertilizer seems promising in mungbean cultivation as this treatment (F
) gave the highest
seed yield (2.24 tha
-1
) along with the highest pod length (8.94 cm), pods plant
3
(34.49), seeds
pod
-1
(12.51) and 1000 seed weight (40.38 g). Among the interactions, O
2
F
out yielded other
combined treatment by producing highest yield (2.48 tha
-1
3
). This interactions produced the
tallest plant (43.48 cm), maximum dry weight plant
-1
(13.71 g), pod length (9.21 cm), pod
plant
-1
(36.31), seeds pod
-1
(12.88), 1000 seed weight (41.30 g), shelling percentage
(71.62%), strover yield (5.52 tha
-1
), biological yield (8.00 tha
-1
), harvest index (34.13%),
germination percentage (94.33%), speed of germination of seed (10.27), seedling shoot
length (22.670 cm), seedling dry weight (0.0430 g) and lowest EC test value (1628.1 µS cm
1
). The study clearly indicated that the residual effect of vermicompost as organic fertilizer
and the recommended dose of chemical fertilizers and combination of vermicompost and
recommended doses of chemical fertilizer might be an option for producing maximum yield
and quality seed of mungben.
