Abstract/ Executive Summary:

A field experiment was conducted to find out an integrated management package for controlling root knot nematode Meloidogyne incognita. of Country bean. Efficacy of two organic soil amendments Poultry refuge and Mustard oil cake, Furadan 5G alone or its integration were tested in the field. Treatments namely, Furadan 5G, poultry refuge, Mustard Oil Cake and their combination like Poutry refuge+ Furadan 5G and Mustard Oil Cake + Fuardan 5G were treated in the field. All the treatments performed better and most importantly poultry refuge alone and its combinations with Furadan 5G gave the most satisfactory result by controlling nematode population and increased yield up to five times more than the control treatment.

Location: BARI, Gazipur

Start Date: 00-00-2010

End Date: 00-00-2011

Program Area: Pest Management

Commodity: Country bean

Objectives:

To observe the effect of two organic soil amendments namely, poultry refuge and mustard oil cake along with a chemical nematicide Furadan 5G( Carbofuran) in controlling the root knot nematodes in Country bean.

Methodology:

The field experiment was carried out during Rabi 2010-11, at the experimental field of Plant Pathology Division, BARI, Gazipur. The field was prepared with power tiller and prepared raised pit with keeping 80 cm distance from pit to pit. There were 8 treatments viz. 1.Control 2. furadan 5G @ 6gm/pit 3. Poultry refuge (PR) @1kg/pit 4. Poultry refuge @0.5 kg/pit 5. Poultry refuge @ 0.5 kg /pit + Furadan 5G @ 3gm /pit 6.Mustard oil Cake 100 gm/pit 7.Mustard Oil cake@50gm/pit and 8.mustard oil cake @50gm/pit + Furadan @3gm/pit. RCBD design was followed with 6 replications. Poultry refuge and MOC were applied three weeks before seed sowing and were incorporated with the soil properly for well decomposition. The nematicide Furadan 5G was applied at the time of seed sowing. The root knot nematode infected roots of tomato and country bean were collected from nematode sick bed and cut into pieces and used as inoculum @ 20gm/pit. The seeds of country bean variety local Jessore were sown in the pits and each pit received 10 seeds. Sixty days after germination, seedlings were uprooted to observe gall in early stage. After germination of seeds, five seedlings in each pit were kept to grow until harvest of fruits and to collect final data. Data collection: The following data were recorded by standard procedure. 1. yield (Fruit weight) 2. Gall index (0 -10 scale) (Zeck, 1971)

Achievement/Findings:

The highest yield of Country bean was recorded in treatment T₃ ( Poultry refuge@ 1kg/pit) followed by T₅= ( Poultry refuge+ Furadan 5G @ 3gm/pit). Moreover, the highest gall index value 2.17 was observed from control treatment. Poultry refuge alone and in combination with Furadan 5G significantly reduced gall of Country bean in comparison to control.
