      abstract = {An experiment was conducted at the Soil Science Field  Laboratory of Bangladesh Agricultural  University,
Mymensingh during the aman season of 2012 to  investigate the effects of prilled urea (PU), urea super  granule
(USG) and NPK briquette on NH4- N concentration in  field water, yield and nitrogen (N) use efficiency (NUE) of  BR22
rice under reduced water conditions. The experiment  was laid out in a randomized complete block design with  three
replications. There were altogether eight treatment  combinations viz. T1: Control (No N fertilizer), T2: 52 kg  N ha-1
from USG, T3: 104 kg N ha-1 from USG, T4: 78 kg N  ha-1 from PU, T5: 120 kg N ha-1 from PU, T6: 51 kg N ha-1  from
NPK briquette, T7: 78 kg N ha-1 from USG and T8: 78 kg  N ha-1 from NPK briquette. Water samples were  collected
from rice field for seven consecutive days after  deep placement of USG and the first split application of PU  and the
samples were analyzed for NH4-N. The Highest  concentration of NH4-N in water was observed at the second  day of
PU application followed by gradual decrease with  time. The yield contributing characters like plant height,  panicle
length, number of effective tillers hill-1 and  grains panicle-1 were significantly influenced by different  treatments. The
highest grain yield of 3.93 t ha-1 was  recorded from 104 kg N ha-1 as USG (T3) and the lowest  value of 2.12 t ha-1 was
obtained from control. The N use  efficiency was increased when the N was applied as USG. The  overall results
revealed that application of USG and NPK  briquette may be practised for obtaining better yields in  addition to
increasing the efficiency of N fertilizer.},
