Thirteen plant specics were planted in pots experiment namely 6 vegetables Chinses kale, Chinese mustard, Chinese cabbage, chiness radish, lettuce and tomato and 7 field crops such as mungbean, soybean groundnut, roselle, white sesame, safflower and sweet corn watered with 5 salinity for ranging from 0.2 to 8 ds/m. Results showed that as salinity of irrigated water increased growth and plant crop yields decreased. The tolerance of vegetable are chinese Kalechinese radishchinese mustardchinese cabbageleaf lettucein the following sequence ranging from high to low and field crops are safflowersoybeansweet corntomatomungbeansesame and groundnut in the following sequence ranging from high to low, respectively. The salinity of water at 1.6-2.95, 1.8-3.08, 3.25-5.1, 7.3 and 7.8 dS/m caused the decrease in relative crop growth. Fresh and dry weight decreased by the decrease in 50 % leaf-lettuce, chinese cabbage, chinese mustard, chinese radish and chinese kale up to 3.95-4.1, 5.0-5.5, 6.8-6.9, 7.75-8.0 dS/m, respectively. Furthermore, it has been found that salinity increased the crop duration of sensitive species decreased. However, durating of tolerant species did not change with increasing salinity.
