Abstract:
The experiment was conducted during the period from November 2015 to
April, 2016 to study the performance of urea super granule (USG) and NPK
briquettes on growth and yield of boro rice (BRRI dhan28). The experiment
consists of the following treatments: T
1
ii
: No fertilizer; T
2
: RFD (Recommended
Fertilizer Dose) for Boro rice; T
3
: 1 granule of NPK of 2.4g weight in between
4 hills + SZn; T
4
: 2 granule of NPK of 2.4g weight in between 4 hills + SZn;
T
5
: 3 granule of NPK of 2.4g weight in between 4 hills + SZn; T
6
: 1 Urea
Super Granule of 2.7g weight in between 4 hills + PKSZn; T
7
: 2 Urea Super
Granule of 2.7g weight in between 4 hills + PKSZn; T
8
: RFD + 1 Urea super
granule of 2.7g weight in between 4 hills. The experiment was laid out in
Randomized Complete Block Design (RCBD) with three replications.
Application of urea super granule (USG) and NPK briquettes expressed
significant influence on growth attributes as well as grain and straw yields of
BRRI dha28. The highest grain yield (7.03 t/ha) was obtained in the T
6
(1 Urea
Super Granule of 2.7g weight in between 4 hills + PKSZn) treatment which
was significantly greater than that obtained from the rest of the treatments used
in the experiment. The highest straw yield (7.77 t/ha) was obtained in the T
6
(1
Urea Super Granule of 2.7g weight in between 4 hills + PKSZn) treatment
which was significantly greater than that obtained from the rest of the
treatments. The lowest grain yield (4.09 t/ha) was recorded in T
1
and lowest
straw yield (4.78 t/ha) was recorded in T
4
.
Although maximum number of total
grain/panicle (180.87) was obtained in the T
8
but maximum number of filled
grain/panicle (157.7) was obtained in the T
6
. So, the treatment T
6
(1 Urea Super
Granule of 2.7g weight in between 4 hills + PKSZn) may be recommended for
profitable cultivation of boro rice, BRRI dhan28.
