Abstract:
Field experiments were conducted in kharif and rabi seasonsto study the volatilization
losses under different nitrogen management practices in transplanted rice. The treatments receiving
application of urea 111 three splits and the combined applica tion of urea and green leaves in 1:1
proportion on N basis recorded the lowest N loss through volatilization in both seasons. Seventy
five per cent of ammonia volatilization was recorded within 6 days after fertilization. The loss was
more during rabi season and the losses significantly increased with increase in pi I, I ICC>3~ and
Nl Lj-N content of flood water.
