Abstract

Abstract : An experiment was conducted to study the biochemical response of rapeseed ( Brassica campestris L.) to sulphur (S) fertilization at grey terrace soil. There were five treatments: S0 (control), S1 (20 kg S ha −1 ), S2 (40 kg S ha −1 ), S3 (60 kg S ha −1 ) and S4 (80 kg S ha −1 ). Chlorophyll content in the leaf was determined at 30, 40, 50 and 60 days after emergence (DAE). The biochemical properties were found responsive to S. The highest chlorophyll content of mustard leaves was found in 60 kg S ha −1 at 50 DAE. The same treatment also showed the maximum N content in the leaves at 45 DAE. The highest oil content was recorded in 60 kg S ha −1 . Other chemical characters such as acid value, peroxide and saponification values were lowest in 60 kg S ha −1 while iodine value was found highest in the same S level. Non-essential fatty acids such as palmitic, stearic and erucic acid were increased in the rapeseed with decrease in S level, whereas essential fatty acids were maximum in 60 kg S ha −1 . Therefore, 60 kg S ha −1 can be recommended to produce quality rapeseed in grey terrace soil of Bangladesh.
