Item Effect of nitrogen management practices on ammonia volatilization losses in transplanted rice(Kerala Agricultural University, 1994) Anila Kumar, K; Menon, P K G; Sivakumar, CField 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.Item Intake, retention and depletion of water in different rice soils as related to their physico-chemical properties(Kerala Agricultural University, 1994) Hassan, M A; Anila Kumar, KItem Nitrogen losses from the rice soils of Kerala with special reference to ammonia volatilization(Department of Soil Science and Agricultural Chemistry, College of Horticulture, Vellanikkara, 1989) Anila Kumar, K; Rajaram, K P
