Abstract:
The experiment was conducted at Sher-e-Bangla Agricultural University, Dhaka-1207 during the
period from December 2018 to March, 2019 to find out the effect of bio-fertilizer on growth and
productivity of soybean varieties. Two factors were used in the experiment, viz. Factor A:
varieties 4 (V1 = Shohag (PB-1), V2 = BARI Soybean-6, V3 = Binasoybean-1, V4 = Binasoybean5) and Factor B: Biofertilizer level 3 (F0 = No biofertilizer (control), F1 = Rizobium (Soybean
Ishwardi) and F2 = Rizobium (Soybean Laxmipur)). The experiment was laid out in a
Randomized Complete Block Design (RCBD) with two factors and three replications. Variety,
biofertilizers and their interaction had significant effect on plant height, number of branch,
number of leaf at different DAS, pods plant-1
, pod length, seeds pod-1
, 100 seeds weight, grain
yield, straw yield, biological yield and harvest index (%).The highest plant height (18.19, 27.20,
44.45, 54.96 and 57.42 cm, respectively), number of branch plant-1
(2.29, 3.08, 3.58, 4.08 and
4.27, respectively) and number of leaves (16.98, 27.71, 37.92, 43.35 and 45.30 cm) were
recorded in Binasoybean-5 with the application of Soybean Laxmipur (V4 × F2) where the lowest
plant height (11.54, 17.26, 28.21, 34.88 and 36.44 cm, respectively), number of branch plant-1
(1.60, 2.16, 2.51, 2.86 and 3.00, respectively) and number of leaves plant-1
(16.00, 24.03, 32.10,
37.41 and 39.09, respectively) were found in no biofertilizer (control) application with the
variety Shohag (PB-1) (V1 × F0) at 25, 35, 45, 55 DAS and at harvest. The highest days to 1st
flowering (49.28 days), number of pods plant-1
(16.98), pod length (5.53 cm), number of seeds
pod-1
(3.31) and weight of 100 seeds (14.05 g) was observed in the variety Binasoybean-5 with
the application of Soybean Laxmipur (V4 × F2) and the lowest days to 1st flowering (34.57 days),
number of pods plant-1
(16.00), pod length (3.88 cm), number of seeds pod-1
(2.33) and weight of
100 seeds (9.86 g) were observed in control with the variety Shohag (PB-1) (V1 × F0). The highest stover yield (16.98), stover yield (4.55 t ha-1
), biological yield (6.55 t ha-1
) and harvest
index (30.49 %) was observed in variety Binasoybean-5 with the application of Soybean
Laxmipur (V4 × F2) and the lowest stover yield (16.00), stover yield (3.96 t ha-1
), biological yield
(5.53 t ha-1
) and harvest index (25.34 %) was observed in control with the variety Shohag (PB-1)
(V1 × F0). It has been appeared that Binasoybean-5 with the application of Soybean Laxmipur
(V4 × F2) produces greater yield over treatments still requires further verification under different
soybean. |
