Abstract/ Executive Summary:

Soil amendments with Sand, Ash, Sawdust, Cowdung, Poultry refuse, Neem compost, Vermi compost along with Control were evaluated for seed germination, seedling growth and control of damping off disease of eggplant and tomato. Soil application of Poultry refuse (T₆), Neem compost (T₇) and Vermicompost (T₁) showed better performance in controlling damping off seedlings as well as increased seed germination and influenced growth characters. The highest seedling population 89.67% at 18 DAS in eggplant and 93.00% at 13 DAS in tomato were recorded under the treatment Poultry refuse (T₆) where seed germination was increased 40.11% and 37.43% over control in eggplant and tomato, respectively. Poultry refuse reduced damping off incidence by 90.56% (30 DAS) in eggplant and 84.81% (25 DAS) in tomato seedlings over control, respectively. Seedlings growth characters like shoot length, root length, seedling height, fresh shoot weight, fresh root weight and fresh seedling weight of eggplant and tomato were also enhanced by poultry refuse. Application of neem compost and vermicompost also showed promising effect against damping off disease and also enhanced seed germination and growth characters of eggplant and tomato seedlings.

Start Date: 00-09-2007

End Date: 00-12-2007

Program Area: Crop-Soil-Water Management

Commodity: Brinjal, Tomato

Objectives:

To evaluate the efficacy of different soil amendments against damping off disease as well as evaluate their effect on seed germination and seedling growth of eggplant and tomato seedlings

Methodology:

The pot experiment was conducted in a completely randomized block design with three replication during the period of September 2007 to December 2007 in the Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka. Eggplant variety BARI Begoon 4 (Kazla) and Tomato variety BARI Tomato 2 (Ratan) were used in the experiment. The treatments were: T₁= Soil amendment with Vermicompost, T₂= Soil amendment with Sand, T₃= Soil amendment with Ash, T₄= Soil amendment with Saw dust, T₅= Soil amendment with Cowdung, T₆= Soil amendment with Poultry waste, T₇= Soil amendment with Neem compost and T₈= Control. Different treatment materials were mixed at 1:3 ratio with experimental soil. After soil amendment experimental pot were left for one month. Then the soil was exposed and pulverized before sowing. Data were recorded on percent seedling population, damping off disease incidence at different days after sowing and seedling growth characters such as shoot length, root length, seedling height, fresh shoot weight, fresh root weight, fresh seedling weight at 30 DAS for tomato and 45 DAS for eggplant. The disease incidence was calculated by the following formula:

% Disease Incidence = Number of infected plant(s) ÷ Number of total plants X 100

The data were statistically analyzed using computer package program (MSTATC). Treatments means were compared by DMRT (Duncan’s Multiple Range Test).

Achievement/Findings:

Among the applied soil amendments, application of poultry waste, neem compost and vermicompost could be used as eco-friendly approach and may be advised to the farmers for the management of damping off disease of vegetable seedlings and as well as increasing seed germination and seedling growth.
