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.

Sixty (60) samples of goat milk from udder halves were analysed. The samples were grouped into Normal, Subclinical 1 + , Subclinical 2 + , Subclinical 3 + and Clinical, based on the score of California Mastitis Test (CMT). The average Somatic Cell Count (SCC) of milk was lowest (7.17 ± 0.11 x 10 5 cells/ml) in normal group and highest (48.62 ± 1.00 x 10 5 cells/ml) in Clinical group. The average SCC of milk for Subclinical 1 + , Subclinical 2 + and Subclinical 3 + were 13.29 ± 0.56 x 10 5 cells/ml, 28.58 ± 0.66 x 10 5 cells/ml and 41.08 ± 0.50 x 10 5 cells/ml, respectively. These results indicated increase in SCC of milk with increase in the severity of the mastitis. As such, if the threshold level is established, the SCC of milk can be used as a diagnostic value for clinical and subclinical conditions of udder infections in does.
