Abstract/ Executive Summary:

The experiment was conducted at the sick plot, Pulses Research Station, Ishurdi, Pabna during 2010-11 to find out the effective BARI Rhizobium strains against foot and root rot of chickpea. Foot and root rot incidence ranged from 9.78-26.63%, while the lowest incidence was recorded in BARI Chickpea Rajshahi and the highest incidence was recorded in untreated control. The highest number of pod/plant (47.80 a), number of seeds/plant (71.63), weight of seeds/plant (9.58 g) and yield (2090.55 t/ha) were obtained from BARI Chickpea Rajshahi and the lowest of these parameters were obtained from untreated control.

Keywords: Chickpea, Foot and root rot, BARI Rhizobium

Location: RARS, Ishurdi

Start Date: 09-11-2010

End Date: 16-03-2011

Program Area: Pest Management

Commodity: Chickpea

Objectives:

To find out the effective BARI Rhizobium strains against foot and root rot of chickpea.

Methodology:

The experiment was conducted at the sick plot, Pulses Research Station, Ishurdi, Pabna during 2010-11. The experiment was carried out following Randomized Complete Block Design with three replications. The unit plot size was 3.0 m X 1.1 m and plant spacing was 40 cm x 5 cm for the experiment. Six BARI Rhizobium strains viz. BARI Rca 201, BARI Rca 220, BARI Rca 202, BARI chickpea Rajshahi, BARI Rca IC 59, Chickpea pulse 1 were used. Seeds of BARIchola 1 were inoculated with BARI Rhizobium strains @ 40 g per kg seeds before sowing. Seeds were sown on November 9, 2010. Intercultural operations were done as per needed and to maintain the normal hygienic condition of crop in the field. During the growing period the plots were inspected regularly to record the incidence of foot and root rot disease from seedling to maturity stage of the crop. Dead plants were removed from the field after counting. Disease plant parts were collected in laboratory for identifying foot and root rot pathogens. The crop was harvested on March 16, 2011. Data were recorded on foot and root rot, plant survival, plant height, number of pods/plant, number of seeds/plant, weight of seeds/plant and yield. The data were analyzed statistically and means were separated by Duncan’s New Multiple Range Test (DMRT).

Achievement/Findings:

All BARI Rhizobium strains showed significant effect on foot and root rot disease of chickpea. The lowest incidence was recorded in BARI Chickpea Rajshahi and the highest incidence was recorded in untreated control. All other BARI Rhizobium strains significantly reduced the foot and root rot disease incidence compared to control. Plant height was not significantly influenced by Rhizobium strains. Number of pod/plant, number of seeds/plant, weight of seeds/plant and yield under BARI Rhizobium strains varied significantly from one strain to another. The highest number of pod/plant (47.80), number of seeds/plant (71.63), weight of seeds/plant (9.58 g) and yield (2090.55 kg/ha) were obtained from BARI Chickpea Rajshahi and the lowest of these parameters were obtained from untreated control.
