Salinity Effect on Yield and Component Characters in Rapeseed and Mustard Varieties

M. R. Islam, M. A. R. Bhuiyan, B. Prasad, M. H. Rashid and M. A. Quddus


Varieties Rai-5, Shambal and Daulat of Brassica juncea and varieties Barisarisa-7 and Barisarisa-8 of Brassica napus were tested for yield and component characters under different levels of soil salinity. The variations due to salinity levels, varieties and variety-salinity (interaction) were significant for different characters. The variable degrees of increase and decrease of regression coefficient estimates (curve estimation) indicated the performance as influenced by different salinity levels. The performance of the variety Barisarisa-7 in plant height and days to first flowering is the best followed by Barisarisa-8 and Daulat. Barisarisa-8 showed the best performance in days to maturity followed by Barisarisa-7 and Shambal. Shambal followed by Daulat and Barisarisa-7was performed incase of number of siliqua per plant. Daulat performed better than others incase of seed per plant and seed yield per plant followed by Rai-5. Considering all the characters the most tolerance ability was found in Daulat under B. juncea and Barisarisa-7 under B. napus which were followed by Barisarisa-8 of B. napus against different levels of salinity.
