Abstract
The experiment was conducted at the
Agronomy farm of Sher-e-Bangla Agricultural University of Bangladesh
during March to June 2015 to identify the influence of different
combinations of inorganic and organic fertilizers in sesame. There
were 12 treatment combinations such as; T0 = control, T1 = chemical
fertilizer, T2 = mixed fertilizer, T3 = cowdung + 25% FRD (fertilizer
at recommended dose), T4 = vermicompost + 25% FRD, T5 = poultry
manure + 25% FRD, T6 = cowdung + 50% FRD, T7 = vermicompost + 50%
FRD, T8 = poultry manure + 50% FRD, T9 = cowdung + 75% FRD, T10 =
vermicompost + 75% FRD, T11 = poultry manure + 75% FRD. The
experiment was laid out following Randomized Complete Block Design
(RCBD) with three replications. The result revealed that application
of chemical fertilizer gave highest seed yield (1656.4 kg ha-1) which
may be attributed to the highest number of capsule plant-1 (88.93),
number of seeds capsule-1 (68.67), 1000 seed weight (2.83g), stover
yield (2309.82 kg ha-1) and harvest index (42.35) as were obtained
with this treatment. But treatment combination consisted of poultry
manure + 75% FRD and vermicompost + 75% FRD also produced
statistically similar seed yield as well as yield attributes as were
observed with chemical fertilizer. So, considering the soil
amendment, the poultry manure + 75% FRD and vermicompost + 75% FRD
seems to be promising in sesame cultivation which reduces the use of
25% chemical fertilizer.
