Screening of BARI Rhizobium Biofertilizers against Foot and Root Rot of Chickpea

Abstract

The experiment was conducted at the sick plot, Pulses Research Centre, Ishurdi, Pabna, Bangladesh during two consecutive years of 2010-11 and 2011-12 to screen out the effective BARI Rhizobium Biofertilizers against foot and root rot of chickpea. Six BARI Rhizobium strains viz. BARI Rca 201, BARI Rca 220, BARI Rca 202, BARI chickpea Rajshahi, BARI Rca IC 59 and BARI Chickpea pulse 1 were used as treatments. In 2010-11, foot and root rot incidence ranged from 9.78-26.63%, while the lowest incidence was recorded in BARI Chickpea Rajshahi, but the highest incidence was recorded in untreated control. BARI Chickpea Rajshahi gave the highest plant survival (90.22%) and control treatment gave the lowest plant survival (72.55%). BARI Chickpea Rajshahi treated plots reduced maximum foot and root rot incidence (63.27%) over untreated control. Similar trends of the results were observed in 2011-12. The highest yield was obtained from BARI Chickpea Rajshahi with 2090 and 2040 kg/ha during 2010-11 and 2011-12, respectively, and the lowest yield was obtained from untreated control for both the years.
