| Popis: | An experiment was conducted at Tuber Crops Research Centre, BARI, Bogra during 2008-2009 to evaluate the organic amendment for controlling the stem canker and black scurf of potato. The different kinds of organic amendments were: T 1 =Poultry refuse (PR) at 4 t ha -1 , T 2 =PR at 5 t ha -1 , T 3 =PR at 6 t ha -1 , T 4 =Mustard oil cake (MOC) at 300kg ha -1 , T 5 =MOC at 500kg ha -1 , T 6 =Neem oil cake (NOC) at 300kg ha -1 , T 7 =NOC at 500kg ha -1 , T 8 =Sawdust burning and T 9 = Control. The experiment was laid out in a randomized complete block design (RCBD) with four replications. The organic amendment significantly influenced the disease incidence, yield attributes and yield of potato. The lowest disease incidence (17.5%) and per cent disease index (9.99) were found in T 3 (poultry waste at 6 t ha -1 ). The minimum russet, deformed and Sclerotia infected tubers were also recorded in poultry waste at 6 t ha -1 . The highest healthy tubers and tuber yield were found in the same treatment. Therefore, poultry manure 6 t ha -1 along with recommended dose of chemical fertilizer can be recommended to produce healthy tubers and maximum tuber yield of potato. |
