| dc.description.abstract | An experiment was conducted at the farm of the Bangladesh Agricultural
Development Corporation (BADC), Khadimpara, Sylhet 3100 during the period
from August to November, 2014 to see the effect of K, S and Zn application on
the performance of BRRI dhan56 regarding to growth, yield and yield
contributing characters under the acidic soil in Sylhet region. The experiment
consists of eight treatments viz, Control, K80, S12, Zn1.8, K80S12, K80Zn1.8, S12Zn1.8
and K80S12Zn1.8. The experiment was laid out in a Randomized Complete Block
Design (RCBD) with three replications. Data were taken on plant height, number
of tillers hill
-1
, panicle length, grains panicle
-1
, 1000-grain weight, grain and straw
yields. Soil status of pre- and post harvest soil also analyzed to know the status
due to KSZn application. Result revealed that all the characters except 1000–
grain weight were affected significantly due to application of K, S and Zn where
K80S12Zn1.8 produced the highest plant height (100.40 cm), effective tillers hill
–1
(8.13), longest panicle (27.87 cm) and grains panicle
–1
(146.60). The highest
grain, straw and biological yield of 4.38, 6.03 and 10.40 t ha
–1
, respectively was
also produced from the treatment K80S12Zn1.8. The lowest performance was
observed in the control treatment for all characters. The soil analysis showed that
the nutrient content in post harvest soils under fertilizer applied soil was higher in
comparison to initial soil. | en_US |
