EFFECT OF BIO-FERTILIZER ON GROWTH AND PRODUCTIVITY OF SOYBEAN VARIETIES

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 (V 1 = Shohag (PB-1), V 2 = BARI Soybean-6, V 3 = Binasoybean-1, V 4 = Binasoybean-5) and Factor B: Biofertilizer level 3 (F 0 = No biofertilizer (control), F 1 = Rizobium (Soybean Ishwardi) and F 2 = 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, 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 (V 4 × F 2 ) 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) (V 1 × F 0 ). It has been appeared that Binasoybean-5 with the application of Soybean Laxmipur (V 4 × F 2 ) produces greater yield over treatments still requires further verification under different soybean.
