An experiment was conducted at TCRC, BARI, Gazipur during November 2010- March 2011 to findout an appropriate approach for the management of common Scab of potato. Soil was amended by rice husk, saw dust, saw dust plus ammonium sulphate, and organic manuring by soybean and dhaincha. All the treatments significantly reduced scab severity as compared to control. However, application of rice husk appeared most effective in reducing potato scab in the field.

To develop a cultural approach to reduce potato scab.
This experiment was conducted in TCRC research field in Gazipur. Five treatments and a control were evaluated. Treatments were rice husk, saw dust, saw dust plus ammonium sulphate, soybean and dhaincha. Experimental plots were 3mx3m in size. Three months prior to tuber planting, soil in each plot was amended by 5 kg of dried rice husk, saw dust, saw dust plus 10 g ammonium sulphate in 5L water. At the same time, seeds of soybean and dhaincha were sown in plots at 60 kg/ha. After 40 days of planting, soybean and dhaincha were cut and incorporated in soil. Potato seeds (variety Diamant) were planted on 30 November 2010 with spacing 60 cm row to row and 25 cm seed to seed. All cultural practices were done according to recommendation. Potato was harvested timely. Scab incidence (%), severity (percent surface area) and yield were recorded. The experiment was laid down in RCBD with four replications. Data were analyzed by MSTAT-C program to get ANOVA. Mean separation was done using DMRT at 5% level of probability.
