Abstract/ Executive Summary:

The experiment was conducted at RARS, Ishurdi, Pabna during 2009-10 to find out the effect of bio control agent against foot and root rot of cauliflower. The lowest foot and root rot incidence (6.25 %) was recorded in Soil amendment with Trichooderma harzianum compost (1.0 t/ha) treated plots and the highest (18.75 %) was recorded in control. The yield ranged from 17.91 to 23.05 t/ha, the highest and lowest yields were recorded in Soil amendment with Trichooderma harzianum compost (1.0 t/ha) and untreated control, respectively

Location: RARS, Ishurdi, Pabna

Start Date: 00-00-2009

End Date: 00-00-2010

Program Area: Pest Management

Commodity: Cowpea, Black gram, Chickpea, Lentil

Objectives:

To find out the effect of Mycorrhiza against foot and root rot of lentil, chickpea, blackgram, cowpea

Methodology:

The experiment was conducted at pot house of the RARS, Ishurdi, Pabna during 2009-10. The experiment was carried out following CRD with five replications. Lentil variety BARI masur-1, chickpea variety BARI chola-1, black gram variety BARI mash-1, and cowpea variety BARI cowpea-1 were used in this experiment. Two treatments were T₁= Inoculated (Mycorrhiza) @100 g/pot and T₂=Uninoculated (control) were used for each crop. Seeds were sown on November 10, 2009. There 25 seeds /pot used. 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, seed rot, foot and root rot and plant survival.

Achievement/Findings:

The highest germination of lentil (88.40%) was recorded in Mycorrhizal inoculated pots and the lowest (79.80%) was recorded in uninoculated control. The lowest (11.60%) seed rot was recorded in Mycorrhizal inoculated pots and the highest (20.20%) was recorded in uninoculated control.The incidence of foot and root rot of lentil ranged from 10.60 – 16.58%, where the highest incidence was recorded in uninoculated control and the lowest was in Mycorrhizal inoculated pots. The highest plant survival (89.40%) was obtained from Mycorrhizal inoculated pots and the lowest (83.42%) was observed in uninoculated control The highest germination of chickpea (86.90%) was recorded in Mycorrhizal inoculated pots and the lowest (81.60%) was recorded in uninoculated control. The lowest (13.10%) seed rot was recorded in Mycorrhizal inoculated pots and the highest (18.40 %) was recorded in uninoculated control.The incidence of foot and root rot of chickpea ranged from 7.90 – 13.40%, where the highest incidence was recorded in uninoculated control and the lowest was in Mycorrhizal inoculated pots. The highest plant survival (92.10%) was obtained from Mycorrhizal inoculated pots and the lowest (86.60%) was observed in uninoculated control The highest germination of blackgram (85.30%) was recorded in Mycorrhizal inoculated pots and the lowest (79.10%) was recorded in uninoculated control. The lowest (14.70%) seed rot was recorded in Mycorrhizal inoculated pots and the highest (20.90 %) was recorded in uninoculated control. The incidence of foot and root rot of blackgram ranged from 11.90 – 17.60%, where the highest incidence was recorded in uninoculated control and the lowest was in Mycorrhizal inoculated pots. The highest plant survival (88.10%) was obtained from Mycorrhizal inoculated pots and the lowest (82.40%) was observed in uninoculated control The highest germination of cowpea (87.50%) was recorded in Mycorrhizal inoculated pots and the lowest (80.60%) was recorded in uninoculated control. The lowest (12.60%) seed rot was recorded in Mycorrhizal inoculated pots and the highest (19.40 %) was recorded in uninoculated control. The incidence of foot and root rot of cowpea ranged from 12.60 – 18.80%, where the highest incidence was recorded in uninoculated control and the lowest was in Mycorrhizal inoculated pots. The highest plant survival (87.40.%) was obtained from Mycorrhizal inoculated pots and the lowest (81.20%) was observed in uninoculated control
