EFFECT OF BRADYRHIZOBIUM INOCULANTS ON THE GROWTH AND YIELD OF SOYBEAN VARIETIES PB-1 AND G-2 (Pages : 39 - 48)

The experiment was conducted at the Soil Science farm of Bangladesh Agricultural University (BAU) Mymensingh during the period from January to May 2000. The experimental soil was Sonatala silt loam, a member of hyperthermic aeric haplaquept. The experiment was laid out in a factorial experiment in Randomized Complete Block Design (RCBD) with three replications. Each replication was represented by a block which was divided into 7 plots. The total numbers of plots were 42 and the size of each plot was 4m × 2.5m. The crop used in this study was soybean (Glycine max L. Merr.). The varieties of the crop was PB-1 (Shohag) and G-2. The study comprised of the seven Bradyrhizobium inoculant treatments such as T1: Uninoculated, T2: BINA-SB-1906, T3: BINA-SB-J43, T4: BINA-SB-3407, T5: BINA-SB-J11, T6: BINA-SB- 102 and T7: BINA-SB-J2. Treatments were randomly distributed within the blocks. The overall results of the field experiment showed that Bradyrhizobium inoculation was beneficial in nodulation, plant fresh weight, dry matter production, plant height, seed yield and hay yield of soybean varieties PB-1 and G-2. The G-2 variety of soybean and bradyrhizobial inoculant BINA-SB-102 gave better results than other variety and other inoculants, respectively. Use of Bradyrhizobium inoculants appear to be an effective method for successful soybean production, which may also improve the soil health saving of costly synthetic chemical fertilizer and keep the soil and environment free from pollution.
