Yields of rice can be substantially increased by the use of nitrogenous fertilizers, but the
return to the producer depends very much on the mode of application. This article reviews …

The effect of different methods of nitrogen fertilizer application on the algal flora and
biological nitrogen fixation (Acetylene-reducing activity) in a wetland rice soil was studied in …

Recovery of applied nitrogen by the rice crop is invariably low, often 30–50%(Prasad & De
Datta 1979). The poor recovery has been attributed to different types of losses occurring in …

A field experiment was made during the rainy season of 1982 and 1983 at the Indian
Agricultural Research Institute, New Delhi to study the relative efficiency of prilled urea, urea …

In a field experiment on a typic hapludoll in 1983 and 1984, deep placement of urea
supergranules at 40 and 80 kg N/ha proved to be the best N source, of five tested, for grain …

A laboratory study made with a sandy clay loam soil of pH 7.7 showed that hydrolysis of urea
was slower when applied as urea supergranules (USG) than commercial urea prills. This …

A field experiment was made on rice during the rainy seasons of 1982 and 1983 to study the
relative efficiency of prilled urea and urea super granules (USG) applied broadcast or deep …

A field experiment, made during the rainy seasons oof 1982 and 1983 at the Indian
Agricultural Research Institute, New Delhi, studied the effects of blending urea with …
