    Conversion of urea placed at different depths and its subsequent impact on growth and yield of rice
    (Indian J. of Agric. Sci., 1980-11) Islam, A.; Mandal, R.; Ahmed, Z.; Rashid, M. H.
    In a study on the effect of urea with depths in rice {Oryza sativa Linn.), conversion of urea into NHj-N was maximum at 15 days in most of the treatments and into NOj-N was at 7 days. But with surface placement of urea it continued up to 15 days of placement and thereafter the concentrations of both declined with time in all the treatments. Fertilizers @ 80 kg N + 60 kg P + 40 kg K/ha placed 8-cm depth produced the highest dry matter and grain yield. At this treatment, the rice plants also accumulated highest amount of N in the shoot and grain.
