Field experiments were conducted at Tamil Nadu Agricultural University, Coimbatore during the South West Monsoon and Summer seasons of 1985-86 to evaluate the nutrient uptake and the response of rice varieties to applied nitrogen and its percentage recovery with different water management practices. The results indicated that the N uptake increased with increment of N levels with continuous field submergence. The response to N application and per cent recovery revealed that application of N beyond 150 kg ha" could result in decrease in these parameters. Water stress resulted in lower uptake and hence lower response. The variety CO 37 showed more N uptake, response to applied N and per cent recovery of N than IR 50.
