The experiment conducted at Joydebpur and Comilla with two doses of nitrogen and three doses of gypsum showed that all the treatments significantly reduced the scab incidence over control. Ammonium Sulphate @170 kg/ha-1/4 (as basal) + ½ (at 35 DAP) + ¼ (at 50 DAP) gave the lowest scab infected tuber and PDI value and the highest yield/hectare.

Pest Management
To find out the role of fertilizers and their application in minimizing the disease incidence.
The study was conducted at the BARI research farm, Gazipur and the farmer’s field of Comilla. Apparently health whole tubers of the variety Cardinal were used as planting material. The unit plot size was 3.0 X 3 m, spacing was 60x25 cm. Design was RCB with three replications. There were 10 treatments comprised with different split amount of Ammonium sulphate @150 kg/ha, Ammonium sulphate @170 kg/ha and different doses of Gypsum including control. In control treatment, recommended doses of fertilizers were used. Urea was used as nitrogen source with Gypsum and control. In all treatments recommended doses of phosphorus and potash fertilizers were used. Data were taken on infected tuber (%), PDI value, number and weight of scabby tubers and total yield.
