Abstract: The field experiments on Integrated Nutrient Management in rice were carried out ( Kharif
2010,2011 and 2012 and summer 2011 and 2012) in red loamy soil at Agricultural and Horticultural Research
Station, Kathalagere, Channagiri taluk, Davanagere district of Karnataka, India to develop suitable integrated
nutrient management practices for rice using organic and inorganic sources of nutrients through integration of
paddy straw treated with combination of cow dung slurry @ 5% + Trichoderma harizianum @5 kg ha-1
+
Pleurotus sajor caju @ 5 kg ha-1
.The organic sources of nutrients used in the present study were FYM (Farm
yard manure), paddy straw and Gliricidia sipium. The results of the present investigation clearly indicated that
the supply of recommended dose of NPK with FYM or paddy straw treated with cow dung slurry @ 5% + T.
harizianum @5 kg ha-1
+ P. sajor caju @ 5 kg ha-1
or Gliricidia yielded significantly positive response in
increasing yield attributes like grain and straw yield in rice. The pooled experimental data of five season
experimentation confirmed the results for sustainability of rice productivity.

I. Introduction
Rice (Oryza sativa L.) is one of the most important cereal food crops of India in term of area,
production and consumer preference. India is also the second largest producer and consumer of rice in the
world. In command areas, rice-rice cropping system is the most common practice. The continued use of
inorganic fertilizers over years in paddy field without the application of organic amendments resulted in the
change of soil structure and increase in salinity or alkalinity apart from decreasing the soil fertility. The
availability of Farm Yard manure (FYM), the main source of organic fertilizers, is also one of the limiting
factors for application to the soil. Apart from the FYM, the paddy straw is also an important organic source of
plant nutrients which can be incorporated into the soil to supplement the nutrient requirement of the plant. Since
the paddy straw is available in bulk after each harvest, it could be utilized effectively after proper microbial
decomposition and could be used along with inorganic fertilizers for sustainable production of rice.
Rice straw contains nitrogen (0.5- 0.8%), P2O5 (0.16-0.27%), K2O (1.4-2.0%), S (0.05-0.10%) and Si
(4-7%) per ton on dry matter basis [1]. The composted rice straw is reported to contain 33 per cent carbon and
1.9 per cent N and, the carbon: nitrogen ratio was 18[2] in addition digestible organic matter (51.5%), cellulose
(47.2%), lignin (3.0%) and soluble phenolic compounds (4.3%) [3]. More than 70 per cent of nitrogen released
from the rice straw could be used by the rice crop in soil which receives continuous application of rice straw for
a period of 10 years [4].
The integrated use of both inorganic and organic sources of substrates enhances the efficiency of both
the substances to maintain soil productivity. However, the lack of proper knowledge of the use of organic
sources and their inability to meet the total nutrient requirement of crop to achieve sustained yield levels
resulted in the poor maintenance of soil health. Hence, the integrated application of organic substances with
inorganic fertilizers is not only essential for managing soil health but also to increase crop productivity. A
perusal of literature indicated that there is meager information on rice straw utilization in rice fields either in
combination with inorganic or organic substances.
In view of the above, it was aimed to study the effect of rice straw integration with inorganic fertilizer
and FYM on soil nutrient management for sustainable production of rice in different seasons of the year.

II. Materials And Methods
The field experiments were carried out during 2010-2012 in Kharif and summer seasons (Kharif 2010,
2011 and 2012 and summer 2011 and 2012) in moderately shallow and dark reddish brown clay soils with the
initial soil fertility status of pH
-6.40, 0.68 % organic carbon, 288 kgha-1
available nitrogen, 12.3 kg ha-1
available
phosphorus and 211.4 kgha-1
available potash at Agricultural and Horticultural Research Station, Kathalagere,
Channagiritaluk, Davanagere district that comes under Bhadra (river) command of Karnataka, India situated
between 130
2’ to 130
05’ North latitude and 760
15’ East longitude and an altitude of 561.6 meters above mean
sea level under Southern Transitional Zone ( Zone-7) of Karnataka which receives average annual rainfall of
654.0 mm.
The paddy straw was collected from the freshly harvested rice crop, dried in the field and cut into 12
inch segments then the paddy straw was treated with combination of freshly prepared cow dung slurry @
5%(volume/weight basis) + Trichoderma harizianum @5 kg ha-1
+ Pleurotus sajor caju @ 5 kg ha-1
.The
treatment regimes used in the present study were combination of NPK with FYM treated paddy straw or
Gliricidia sepium
The field experiments were laid out in Randomized Complete Block Design (RCBD) with 12
treatments replicated thrice in a treatment plot size of 8.4 x 6.9 m. The rice seedling nursery and the main crop
were raised as per the package of practices and the nutrient management practices were adopted as per the
experimental treatments [6]. The rice variety JGL-1798 healthy seedlings of 25 days old were planted with the
spacing of 20 cm x 10 cm. The treatment details include-T1:Control (without application of fertilizers), T2:50%
NPK, T3:75% NPK, T4:100% NPK, T5:50% NPK + 50% NPK through FYM, T6:75% NPK + 25% NPK through
FYM, T7:50% NPK + 50% NPK supplied through Paddy Straw treated with cow dung slurry @ 5% + T.
harizianum @5 kg ha-1
, T8: 75% NPK + 25% NPK supplied through Paddy Straw
treated with cow dung slurry @ 5% + T. harizianum @5 kg ha-1
,T9:50% NPK + 50%
NPK supplied through Gliricidia sipium, T10:75% NPK + 25% NPK supplied through Gliricidia, T11:Farmers
Practice(85:50:30 kg NPK ha-1
& 5t ha-1
FYM) and T12:Recommended dose NPK (100: 50: 50 kg NPK) + 10 t
ha-1
FYM.
The observation on yield attributes (productive tillers/hill and panicle weight), grain and straw yield of
rice were recorded at harvest and the data were subject for statistical ANOVA at P= 0.05 [5].
III. Results And Discussion
The pooled data of five seasons ( Kharif 2010,2011 and 2012 and summer 2011 and 2012) on yield
attributing factors revealed that the application of 75% NPK + 25% NPK supplied through Paddy Straw treated
with cow dung slurry @ 5% + T. harizianum @ 5 kg ha-1
treated plots had
significantly enhanced the number of productive tillers (19.42 per hill) and panicle weight (4.76 g per plant) as
compared to application of 100% NPK alone supplied through inorganic fertilizers ( 17.86/hill and 4.13 g,
respectively) [T8] followed by the application of 50% NPK + 50% NPK through paddy straw with cow dung
slurry @ 5% + T. harizianum @ 5 kg ha-1
[T7] (TABLE 1 & 2). The enhanced yield
attributing factors were related to the release of plant nutrients by the process of microbial degradation of rice
straw according to the plant demand.
Similarly, the pooled data of five seasons on grain and straw yield revealed that application of 75%
NPK + 25% NPK supplied through paddy straw treated with cow dung slurry @ 5% + T. harizianum@5 kg ha-1
treated plots recorded significantly highest yield of grain (7201 kg ha-1
) and straw
yield (9000 kg ha-1
) compared to application of 100% NPK alone supplied through inorganic fertilizers (6896 kg
ha-1
and 8609 kg ha-1
, respectively) and on par with the application of recommended dose of NPK + 10 tons
FYM ( 7050 kg ha-1
and 8829 kg ha-1
, respectively).
The results of the present investigation clearly indicated that supply of recommended dose of NPK
either through inorganic and organic sources showed that nutrients supplied in combination with FYM or paddy
straw treated with cow dung slurry @ 5% + T. harizianum @5 kg ha-1
+ P. sajor caju@ 5 kg ha-1
(T8) or
Gliricidia (T10) had significantly positive response in increasing yield attributes, grain and straw yield in rice.
The increased rice yield could be due to return of available nutrients in the form of NPK, C and other
minerals from decomposed rice straw treated with T. viridae to soil [6] as suggested by Man et al. In another
experiment Man et al showed that application of rice straw decomposed with Trichoderma spp and combined
with 50% NPK fertilizers increased rice yield over application of chemical fertilizers alone[7]. It has been
shown that the integrated use of fertilizers and manure or crop residue could be an efficient practice for getting
high crop yields in rice without degradation of soil fertility [8]. Studies conducted have also shown that use of
12 t ha-1
FYM and 60 kg/ha N [9] and application of 12 t ha-1
FYM in combination with 80 kg ha-1
N [10]
produced rice yields equivalent to that obtained with 120 kg ha-1
N. Also, application of 75% NPK through
fertilizers + 25% through Glyricidia or rice straw [11], 25% recommended N through FYM and 50%

recommended NPK through fertilizers plus 50% NPK through compost and FYM recorded similar rice grain
yields as that of 100% NPK applied through fertilizers[12].
The results of present investigation suggested that the application of 75% NPK through chemical
fertilizers in combination with 25% NPK supplied through Paddy Straw treated with cow dung slurry @ 5% +
T. harizianum @5 kg ha-1
was the best integrated nutrient management practices in
rice, since there was a balanced combination of organic and inorganic source of nutrients.
IV. Conclusion
The results of the present study showed that the application of the combination treatments of 75% NPK
+ 25% NPK supplied through Paddy Straw treated with cow dung slurry @ 5% + T. harizianum @5 kgha-1
+ P.
sajor caju @ 5 kg ha-1
helped in the balance maintaining the organic and inorganic nutrients in soil and hence the
increased rice productivity. The present study also showed that rice straw could be efficiently exploited for
conservation of soil nutrients under rice ecosystem through proper decomposing techniques, simultaneously
enhancing soil microorganisms beneficial for plant growth and productivity.
