Abstract
 Two field experiments were
conducted
at
the experimental farm of
Sakha
Agricultur
e R
esearch Station, S
akha, Kafr El
-Sh
eikh, Egypt during 2017 and 2018
seasons. The aim
of th
e current investigation
was to study the effective
of bio and
organic fertilizer
s in declining the mineral nitrogen fertilizer in rice fields (
Sakha 108 c
v.)
.
The treatments were:
T
1
: 165
kg N/ha
as
recommended
nitrogen rate (R
N), T
2
:
⅔
RN, T
3
:
⅔ R
N + 5 t/ha
poultry manure as organic fertilizer,
T
4
:
⅔
RN +
Anab
aena or
yza
e
(N
– fixing
anabaena) as bio
-fertilizer
, T
5
:
⅔
RN + organic manure + bio
-fertilizer,
T
6
:
⅓ R
N, T
7
:
⅓ RN
+ organic manure
, T
8
:
⅓ RN
+ bio
-fertilizer and
T
9
:
⅓ RN
+ org
anic manure + bio
-fertilizer.
The obtained results revealed that the integration among mineral, organic and bio
-
fertilization of T
5
(110kg N/ha + 5 t/ha poultry manure +
600 g/ha N
-fixing anab
aena) gave
the maximum values of tillers number m
-2
, days to hea
ding, dry matter accumulation, flag
leaf chlorophyll content, flag leaf area, leaf
area index, panicles number m
-2
, panicle
weight, 100-
grain weight, grain yield, straw yield, milling percentage and grain protein
content, as well as, the lowest number of u
nfilled grains panicles
-1
. However, the
differences between T
5
and
T
1
(165
kg N/ha as recommended mineral N
level) in panicles
number
m
-2
, number of unfilled grains per panicle, straw yield
, milling percentage and
grain protein content
were insignificant.
In addition, T
1
gave the tallest
plants and the
maximum values of number of
filled grains per panicle and hulling percentage, but the
differences with T
5
in number of filled grains panicle
-1
and
hulling percentage were
insignificant.
Number of branches pan
icle
-1
, panicle length, harvest index and head rice
had insignificant response
. It could sum up that adding ⅔ of the recommended mineral
nitrogen plus of 5 t/ha of poultry manure plus 6
00 g/ha
of
N-fixing anab
aena could be the
recommended for reducing min
eral nitrogen fertilizer and brining high grain yield of
Sakha 108 rice variety.
