Abstract

A field experiment was conducted during kharif 2017-18 to investigate the effect of nitrogen application through urea and azolla on growth, yield of rice (Oryza sativa L.) and temporal soil phosphorus availability with six treatments viz., control (T1), Azolla incorporation @ 16000 kg ha-1 (T2), 30 kg N ha 1through urea(T3), 60 kg N ha 1through urea(T4), 30 kg N ha 1through urea+ Azolla incorporation @ 16000 kg ha-1 (T5) and 60 kg N ha 1through urea with Azolla incorporation @ 16000 kg ha-1(T6) . The experiment was laid out in RBD and replicated four times. The experimental soil was having pH 5.1, SOC 1.75 per cent, available N, P and K as 288.62, 17.23and 201.46kg ha-1, respectively. The experimental results revealed that the application of 60 kg N ha 1 through urea along with azolla incorporation @ 16000 kg ha-1 (T6) recorded highest plant height (118.67 cm) at 90 DAT of rice which is significantly superior over control (98.17 cm) with 17.27 per cent increase. Similarly, 60 kg N ha 1 through urea with azolla incorporation @ 16000 kg ha-1 produced highest grain and straw yield i.e. 4.2 t ha-1 and 7.68 t ha-1 followed by T5 and T4. Further, it was observed that the grain yield obtained in T2 was statistically at par with T3. The grain and straw yield obtained in T4 was also found statistically at par with the values obtained in T5.
