Raziuddin Ansari
Abstract:
Growth performance of S-5, S-9 and S-N varieties of
Brassica campestris
L. (Sarson) and R-l 1-1, R-II-32 and R-II-40 varieties of
Brassica juncea L. (Raya) were tested in soil having 0.2, 0.4 and 0.6% of sodium
chloride and sodium sulphate in equal proportions. With increasing salt
concentrations plant height, grain and plant dry weight, magnesium and
potassium contents generally decreased, while days to flowering, ash,
nitrogen, phosphorus, calcium and sodium contents increased. Taking
plant growth as an index, all varieties were relatively tolerant upto
0.4% salinity whereas at 0.6% salinity effects were pronounced.
