    EFFECT OF Trichoderma harzianum AND SOME SELECTED SOIL AMENDMENTS AGAINST DAMPING OFF DISEASE OF SOME WINTER VEGETABLE
    (DEPARTMENT OF PLANT PATHOLOGY, 2009) UDDIN, MD. MINHAJ
    Effect of Trichoderma harzianum and some selected soil amendments against damping off disease of some winter vegetable were studied in the field condition during the period of 2008-2009 at Sher-e- BangIa Agricultural University, Dhaka. Soil application with poultry waste, cocodust, vermicompost, ash, sawdust, khudepana, cowdung, solarized sand, Trichoderma harzianum and or seed treatment with Trichoderma harzianum were evaluated against damping-off, seed germination and growth characters of potato, tomato, eggplant, chilli, cabbage and cauliflower seedlings. All the treatments were significantly reduced percent damping-off of these six vegetable over untreated control. The most effective treatment was Trichoderma harzianum followed by poultry waste and vermicompost in terms of suppressing damping-off disease incidence with increasing plant growth characters. The highest seed germination percentage of potato (94.00%), tomato (92.00 %), chilli (86.67%), eggplant (94.33%), cabbage (88.00%) and cauliflower (90.00%) was recorded in Til (Seed treatment with T. harzianum + Soil application with T. harzianum). The most effective control measure for damping-off diseases of selected winter vegetable was recorded in Til. The highest growth character was observed in Ttl «Seed treatment with T. harzianum + Soil application with T. harzianumy T12 (Seed treatment with T.~',· harzianum + Soil application with poultry waste) & T14 (Seed treatment with T. harzianum + Soil application with vermicompost) respectively. It was also found that, Trichoderma harzianum treated seed sown in different amended soil showed better result in all parameters than seed sown only on amended soil. Among the different soil amendments, poultry waste and vermicompost have promising effect on seed germination, percent damping-off and seedling growth characters of six selected winter vegetable seedlings.
