Abstract:
An experiment was carried out on BRRI dhan 29 at the experimental field of Sher-c-
l3angla Agricultural University. Dhaka during November'07 to April'08 to evaluate
the elIèct of three forms of N-fertilizer viz. pilled urea. urea super granules (USG) and
foliar spray of urea and four levels of seedling/hill viz. 1. 2, 4 and 6. Forms of N-
fertilizer were assigned in main plot and number of seedling/hill in the sub plots in a
split-plot design with 3 replications
.. EtTect of forms of nitrogen fertilizer and number
of seedling/hill was signilicant in respect of all the plant and yield attributing
characters like plant height. effective tiller/hill, ineffective tiller/hill. grain/panicle.
sterile grain/paniele and thousand seed weight. Urea super granules (USG) have
significantly highest grain yield (6.4
t/ha)
lowest grain (5.1 c/ha) was found in the

grain yield (6.6 t/ha) was obtained from single seedling/hill followed by two
seedlings/hill (6.4 t/ha). The highest straw yield (7.5 c/ha) was obtained from six
seedlings/hill and the lowest (6.7 c/ha) was found from single seedling/hill. The
interaction effect of forms of N-fertilizer and number of seedling/hill differed
significantly for all the yield attributes, although the highest grain yield (7.0 c/ha) was
produced from the treatment combination of Urea super granule (USG)
