Rhizobium sp. BARIRGm901 INOCULATION RESPONSE TO SOYBEAN GENOTYPES IN NORTHERN REGION OF BANGLADESH (Pages : 11 - 19)
F. ALAM, M.W. RAHMAN, M.M. HOSSAIN, M.B. BANU, S.S. ALAM AND M.A.H. BHUIYANA field experiment was conducted by soybean (Glycine max L. Merill) genotypes with Rhizobium sp. BARIRGm901inoculation at the Breeder Seed Production Centre (BSPC), Bangladesh Agricultural Research Institute (BARI), Debigonj, Panchagarh, Bangladesh during 2009-2010 and 2011-2012 with the objectives to find out the response of Rhizobium sp. BARIRGm901 inoculation with different plant genotypes of soybean. Two soybean varieties viz. Shohag and BARI Soybean-6, and two advance lines MTD-10 and BGM-02026 were studied with and without Rhizobium sp. BARIRGm901inoculationin Factorial Randomized Complete Block Design (RCBD) with four replications. Peat based rhizobial inoculum (strain BARIRGm901) was used at the rate of 1.5 kg ha-1 as seed inoculant. Rhizobium sp. BARIRGm901inoculation significantly increased nodulation, dry matter production, pods plant-1 and seed yields of soybean in both years. Nodulation was higher in BARI Soybean-6 and this variety also performed better in respect of shoot weight, pods per plant, stover and seed yield. Among the varieties and advance lines, the highest seed yield 1.73 t ha-1 in 2009-2010 and 1.44 t ha-1 in 2011-2012 was recorded. Interaction effects revealed that inoculated BARI Soybean-6 gave the highest seed yield (1.84 t ha-1 in 2009-2010 and inoculated BGM-02026 (1.60 t ha-1)in 2011-2012. Nodule number and nodule weight was the highest in inoculated BARI Soybean-6 in both years. Therefore, Rhizobium sp. BARIRGm901inoculation established a symbiotic relationship with soybean genotypes and thus increased the nodulation, growth, and yield of soybean grown in northern region of Bangladesh.Download
