Abstract/ Executive Summary:

A field experiment was conducted at the Regional Agricultural Research Station, Hathazari, Chittagong during 2009-2010 to find out the accurate management package for controlling the root-knot disease. The treatment T₅(Poultry refuge @3 t/h + Furadan 5 G @ 20 kg/h, 15 gm/plot) showed the best result. It showed the best performance 64.33 cm shoot length, 198.3g shoot weight, 17.00 cm root length and 16.00% gall index at 60 days and at harvest condition, it also showed 95 cm shoot length, 526.7 g shoot weight, 25 cm root length, 28.72% gall index and yield 43.05 ton/ ha followed by T₈ (Mustard oil cake @ 300 kg / h + Furadan 5 G @ 20 kg/h). T₅ decreased 51.51% and 40.71% gall index at 60 days from planting and at harvest time respectively. It also increased about 132% yield over the control.

Keywords: Brinjal, Root knot nematode

Location: Regional Agricultural Research Station, Hathazari, Chittagong

Start Date: 00-00-2009

End Date: 00-00-2010

Program Area: Pest Management

Commodity: Diseases

Objectives:

To control the root knot nematode of Brinjal in an integrated way

Methodology:

The field experiment was conducted at the Regional Agricultural Research Station, Hathazari, Chittagong during 2009-2010 to find out the a management package for controlling the root-knot disease .Eight treatments were used viz. T₁ = Control, T₂ = Furadan 5 G @ 40 kg/h, 29 gm/ plot, T₃ = Poultry refuge @5 t/h, T₄ = Poultry refuge @ 3 t/h, T₅ = Poultry refuge @3 t/h + Furadan 5 G @ 20 kg/h, 15 gm/plot, T₆= Mustard oil cake @ 600 kg / h, T₇ = Mustard oil cake @ 30 kg / h and T₈ = Mustard oil cake @ 300 kg / h + Furadan 5 G @ 20 kg/h, 15 gm/plot. Firstly, at 60 days from planting of eggplant, the shoot length, shoot weight, root length and root gall data were taken following the Fassuliotis (1973) and modified by Ahmad et al (1987). Lastly when the field was matured, the data of the mentioned parameter were taken. The BARI Begun-1 was cultivated. The experimental field was properly prepared and added recommended doses of manures and fertilizers (Anon, 2006). Four weeks old seedlings of brinjal were carefully transplanted in 2.4m ×3 m unit plot maintaining 75cm row to row and 60cm plant to plant distance. Irrigation and weeding were done as and when necessary.

Achievement/Findings:

All treatment showed the statistically significant results at 5% level. The treatment T₅ (Poultry refuge @3 t/h + Furadan 5 G @ 20 kg/h, 15 gm/plot) showed statistically significant result at 5% level. It showed the best performance 64.33 cm shoot length, 198.3 g shoot weight, 17.00 cm root length and 16.00% gall index at 60 days and at harvest time, it also showed 95 cm shoot length, 526.7 g shoot weight, 25 cm root length, 28.72% gall index and yield 43.05 ton/ ha followed by T₈ (Mustard oil cake @ 300 kg / h + Furadan 5 G @ 20 kg/h). T5 decreased 51.51 and 40.71% gall index at 60 days from planting and at harvest time respectively. It also increased about 132% yield over the control
