Abstract:
An experiment was conducted at the Sher-e-Bangla Agricultural
University during the period from aman season (June-December 2013)
with a vicw to study the effect of different organic manures and chemical
fertilizers on the morphophysiological and yield contributing characters
of transplant anian rice cv. BRRldhan54. There were several treatments
viz. T
1 =Control, T=Recommended dose of NPK , T
3
=Green manure
+1/2 recommended dose of NPK, T
4
Green manure -r2/3
recommended dose of NPK, T5
=Poultry manure +1/2 recommended
dose of NPK, T= Poultry manure ±2/3 recommended dose of NPK,
T7=Cowdung +1/2 recommended dose of NPK. T= Cowdung +2 /3
recommended dose of NPK, T9
=Quick compost +1/2 recommended
dose of NPK, T10= Quick compost +2 /3 recommended dose of NPK,
T11
=Vermicompost +1/2 recommended dose of NPK, T
12=
Vermicompost +2/3 recommended dose of NPK, T1
= Magic growth
+1/2
recommended dose of NPK, T
14 =Magic growth +2/3
recommended dose of NPK. The experiment was laid out in a RCBD
design with three replications. All the plant growth and yield contributing
characteristics were affected at different treatments. Maximum plant
height was attained in T14 treatment (Magic growth +2/3 recommended
dose of NPK). T12 treatment (Vermicompost +2/3 recommended dose of
NPK) produce highest tillers hili'.dry weight, effective tillers hi1l,
panicle length, number of filled grain panic1e, 1000 grain weight, straw
yield, grain yield except harvest index, number of unfilled grain panicle',
and non effective tillers hilL Higher harvest index was found in T
7
treatment (Cowdung + 1/2 recommended dose of NPK). Unfilled grain
panicle', and non effective tillers hill1
were better in untreated plot.
Benefit cost ratio was highest in T2 recommended dose of NPK. Net
return was highest in
T2
.Significantly the highest grain yield was found
in
(5.95
t ha') by the T12 treatment (Vermicompost +2/3 recommended
dose of NPK) and lowest grain yield was found (3.80 t had ) in control or
without fertilization. So. T12 treatment (Vermicompost +2/3
recommended dose of NPK) is the best treatment with combined
application of inorganic fertilizers other than poultry manure, green
manure, cowdung, magic growth, quick compost and solitary application
of inorganic fertilizer.
