Abstract/ Executive Summary:

The experiment was conducted at pot house of the RARS, Ishurdi, Pabna during 2010-11 to find out the effect of Mycorrhiza against foot and root rot of lentil and chickpea. The highest germination was recorded in inoculated Mycorrhizal pots and the lowest was recorded in uninoculated control. The lowest foot and root rot incidence was recorded in inoculated Mycorrhizal pots and the highest was in uninoculated control pots. Inoculated Mycorrhizal pots showed the highest seedling vigour, number of pods/plant, number of seeds/plant, weight of seed/plant and pot yield and the lowest of these parameters were recorded in uninoculated control for both lentil and chickpea.

Keywords: Mycorrhiza, Foot and root rot, Lentil, Chickpea

Location: RARS, Ishurdi

Start Date: 09-11-2010

End Date: 00-00-2011

Program Area: Pest Management

Commodity: Chickpea, Lentil

Objectives:

To find out the effect of Mycorrhiza against foot and root rot of lentil and chickpea.

Methodology:

The experiment was conducted at pot house of the RARS, Ishurdi, Pabna during 2010-11. The experiment was carried out following Completely Randomized Design with five replications. Lentil variety BARI masur-3 and chickpea variety BARI chola-1 were used in this experiment. Two treatments were T₁= Inoculated (Mycorrhiza) @100 g/pot and T₂=Uninoculated (control) were used for each crop. Twenty seeds were sown in each pot on November 9, 2010. Intercultural operations were done as per needed and to maintain the normal hygienic condition of crop in the pots. During the growing period the pots were inspected regularly to record the incidence of foot and root rot disease from seedling to maturity stage of the crops. Disease plant parts were collected in laboratory for identifying foot and root rot pathogens. Data were recorded on germination, foot and root rot, seedling vigour, plant height, no. of pod/plant, no. of seed/plant, wt. of seed/plant and pot yield. The recorded data were analyzed statistically to find out the level of significance and the variations among the respective data were compared following Duncan’s New Multiple Range Test (DMRT).

Achievement/Findings:

The highest germination (95.40%) was recorded in inoculated Mycorrhizal pots and the lowest (90.80%) was recorded in uninoculated control. The incidence of foot and root rot of lentil ranged from 7.55 – 18.39%, where the lowest incidence was recorded in inoculated Mycorrhizal pots and the highest was in uninoculated control pots. Seedling vigour, no. of pods/plant, no. of seeds/plant, wt. of seed/plant and pot yield of lentil were significantly influenced by the treatments. Inoculated Mycorrhizal pots showed the highest seedling vigour (2047), no. of pods/plant (79.60), no. of seeds/plant (91.88), wt. of seed/plant (3.29 g) and pot yield (30.70 g) and the lowest of these parameters were recorded in uninoculated control. The highest germination (97.10%) was recorded in inoculated Mycorrhizal pots and the lowest (91.67%) was recorded in uninoculated control. The incidence of foot and root rot of lentil ranged from 8.33 – 20.91%, where the lowest incidence was recorded in inoculated Mycorrhizal pots and the highest was in uninoculated control pots. Seedling vigour, no. of pods/plant, no. of seeds/plant, wt. of seed/plant and pot yield of chickpea were significantly influenced by the treatments. Inoculated Mycorrhizal pots showed the highest seedling vigour (2451), no. of pods/plant (20.95), no. of seeds/plant (38.69), wt. of seed/plant (3.95 g) and pot yield (28.86 g) and the lowest of these parameters were recorded in uninoculated control.
