Abstract
The study was conducted at the net House, Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh, Bangladesh during 2013 to 2014 to find out the effect of soil salinity on proline content of soybean. The pot experiment was conducted Salinity and variety along or in combination significantly affected the yield and most of the yield attributes of soybean. In case of salinity treatment, plant height, number of leaves plant-1, number of pod plant-1, number of seed plant-1, grain yield, straw yield, biological yield and harvest index were obtained highest when treatment with S2 (2.0 dSm-1) and their lowest value were remained in S14 (14.0 dSm-1). In case of variety treatment, plant height, grain yield, straw yield, biological yield and harvest index were found by Shohag and number of leaves plant-1 number of branches plant-1 were obtained highest with Bangladesh soybean-4 and number of pod plant-1, harvest index were obtained highest with BARI soybean-5. Proline content of soybean grain was also significantly affected by both treatments individually or in combination. Bangladesh soybean-4 individually or in a combination along with other salinity levels and varieties showed positive effect in most cases and consequently for obtaining satisfactory highest grain yield 1763 (kg/ha), straw yield 2784 (kg/ha), biological yield 4547 (kg/ha), harvest index 38.77% and best proline content 39.71% respectively.
