Different rabi crops specially vegetables were screened in saline area under rainfed condition at CDSP II site, Char Majid, Noakhali during rabi season 2003-2004. Five farmer’s lands having different degree of salinity (viz. S1=4 ds/m, S2=6 ds/m, S3=6.5 ds/m, S4=8.0 ds/m and S5=9.0 ds/m) were used for the study. Among the vegetable crops batisak showed better performance in all level of soil salinity but tomato and cabbage resulted better yield in the soil having low salinity. In case of spices and oil seed crops, both the crops produce yield in the land having average soil salinity up to 6.08. With the increase of soil salinity; yields of almost all crops reduced drastically and it was not possible the plant of spices and oil seed crops tested in the study to reach up to maturity to produce yield in the soil having salinity more than 6.08ds/m.
rabi, salinity, crops
To evaluate the variability in salinity tolerance of different rabi crops in coastal area
The experiment was conducted in farmer’s field at CDSP II Site, Char Majid, Noakhali. Five farmer’s field having different degrees of soil salinity (viz. S1=3.49 ds/m, S2=5.75 ds/m, S3=6.08 ds/m, S4=8.23 ds/m and S5=9.14 ds/m) were used for the study. Detailed Salinity status of the experimental site of CDSP II at Char Majid is presented in Appendix 1. Vegetable crops namely; tomato, batisak and cabbage, spices crops viz. chilli and garlic and oil seed crop - mustard were tested in the selected farmer’s field. Seedlings of different crops were raised at the seedbed. Seedlings of different crops at optimum age were transplanted in the main field having unit plot size 5m x 2m. Transplanting was done from December 15 -17, 2003. Recommended spacing and fertilizer doses were maintained depending upon the nature of crops. Weeding was done as and when necessary. Harvesting was done depending upon the crops. Data on yield of different crops were collected.
Annual Research Report, 2003-04 published by OFRD, BARI
Yield of different crops against varying degree of salinity are presented in Table 1. Among different vegetable crops batisak showed better performance in all the fields resulting highest yield in S3 (23.00 t/ha), but tomato and cabbage perform better in lower saline soil. Yield of vegetable crops under study reduce with the increase of salinity and tomato and cabbage could not grow in the soil having salinity more than 8 ds/m. Similar observation was recorded in case of spice and oil seed crops. Chilli resulted better yield in the soil having salinity up to 6 ds/m. the highest yield (0.75 t/ha) of garlic was found in the land having salinity 4 ds/m. With the increase of soil salinity; yield of garlic gradually decreased. Maximum seed yield (385.00 kg/ha) of mustard was recorded from the field with salinity 4 ds/m. With the increase of soil salinity; yields of almost all crops under study reduced drastically and it was not possible the plant of spices and oil seed crops to reach upto maturity to produce yield in the soil having salinity more than 6.50ds/m.
