MANAGEMENT OF FUSARIUM WILT OF BRINJAL (Fusarium oxysporum f. sp. melongenae) BY USING DIFFERENT ORGANIC AMENDMENTS

Abstract

A field experiment was conducted in the central farm of Sher-e-Bangla Agricultural University and lab experiment was conducted in the lab of Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka during the period from September 2021 to April, 2022. The study was carried out to evaluate the effect of selected treatments viz. T 0

= Control ; T 1 = Spent Mushroom Substrate (SMS) ; T 2 = Vermicompost ; T 3 = Poultry manure; T 4 = Biochar ; T 5 = Spent Mushroom Substrate + Biochar ; T 6 = Spent Mushroom Substrate + Poultry manure ; T 7 = Spent Mushroom Substrate + Vermicompost for the management of Fusarium wilt of brinjal. In response to different selected treatments, yield and yield attributes were recorded. On the basis of visible symptoms infected plants and percent disease incidence were also recorded. The lowest disease incidence was found in T 5 (Spent Mushroom Substrate + Biochar) followed by T 6 (Spent Mushroom Substrate + Poultry manure) and the highest disease incidence was found in T 0 . The effect of different treatments on yield and yield contributing characters also studied and significance variation was observed. For yield contributing characters the lowest result was found in untreated control T 0 and the highest result was found in T 5 which was statistically similar with T 6 .In response to different selected treatments for yield, the highest performances was observed where Spent Mushroom Substrate + Biochar was used. From the findings of the present study, it may be concluded that Spent Mushroom Substrate + Biochar and Spent Mushroom Substrate + Poultry manure can be used as ecofriendly approach for the management of fusarium wilt of brinjal. However, further investigation is needed to justify the present findings.
