| dc.description.abstract | Abstract :
A pot experiment was conducted at the Research Farm of Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during 2013-14 to find out suitable organic amendment(s) for increasing germination and yield of potato tubers under saline condition. Three levels of salinity (S2= 4 dS/m, S = 8 dS/m and S =
12 dS/m) along with control (S,) were included in the trial. Tubers of the variety Diamant were planted after placing four different organic amendments viz. A,= saw dust, \= rice straw, A3= ashes and A4= rice bran around the tuber. Results revealed that at 20 DAP, the lowest emergence (16.67%) was recorded in the treatments, where ashes and rice bran were used with high salinity level (12 dS/m). At 25 DAP, 100% emergence was recorded in the treatments, where no salinity was imposed. More than 65% plants were emerged when salinity levels were 4 dS/m or 8 dS/m with any of the amendments used. Whereas, high salinity level (12 dS/m) was maintained and rice bran was used as amendment, the emergence was very low till 25 DAP (16.67%). The highest per plant yield was obtained from the interaction effect of (401.00 g) followed by that of S2A2 (365.33 g), S2A3 (353.50 g), S2A, (350.67 g), S,A3 (347.50 g), and SjA, (343.33 g), S3A, (330.67 g) and S3A2 (325.50 g). Therefore, using organic amendments like saw dust and rice straw, potato can be grown at a condition where salinity level is upto 8 dS/m. | en_US |
