Abstract
A pot experiment was conducted to study the effect of time of nitrogen application at two salinity levels (EC. 1.6 and 10 dS mI). Salinity was developed by a mixture of salts before transplanting rice seedlings of KS 282. Various combinations of different proportions of nitrogen fertiliser was applied to nursery, at transplanting, 10 days after transplanting (10 OAT) and at panicle initiation stage. Tillering capacity, fresh panicle weight, paddy and straw yield decreased significantly at high salinity. Among the nitrogen treatments, grow'th and yield was maximum where 1/2 N was applied 10 OAT and 1/2 at panicle initiation stage. Application of 1/3rd N to nursery bed gave better results in terms of paddy yield at high salinity. Chemical composition of the paddy with respect to N, K +, Na + and Cl" as well as K:Na ratio has been discussed
