4. Indian mustard (Brassica juncea L.) belonging to the family
Cruciferae is one of the major oilseed crop with a high quality of edible
oil (37- 49%). Mustard is the 3rd important oilseed crop in the world after
soybean (Glycine max L.) and Ground nut (Arachis hypogea L.)oil.

5. Integrated Nutrient Management
Concept and Its Role
Definition:
Integrated Nutrient Management refers to the
maintenance of soil fertility and of plant nutrient
supply at an optimum level for sustaining the
desired productivity through optimization of the
benefits from all possible sources of organic,
inorganic and biological components in an
integrated manner.
5
6. Concepts :
1.Regulated nutrient supply for optimum
crop growth and higher productivity.
2.Improvement and maintenance of soil
fertility.
3.Zero adverse impact on agro-ecosystem
quality by balanced fertilization of
organic manures, inorganic fertilizers and
bio-inoculants (biofertilizers).
6
7. The three main role of INM, as defined by
FAO 1998 –
1. Maintain or enhance soil productivity through
a balanced use of fertilizers combined with
organic and biological sources of plant
nutrients.
2.Improve the stock of plant nutrients in the
soils.
3.Improve the efficiency of plant nutrients
limiting the losses in the environment.
7
9. 1. Enhances the availability of applied as well as native
soil nutrients.
2. Synchronizes the nutrient demand of the crop with
nutrient supply from native and applied sources.
3. Provides balanced nutrition to crops and minimizes the
antagonistic effects resulting from hidden deficiencies
and nutrient imbalance.
4. Improves and sustains the physical, chemical and
biological functioning of soil.
5. Minimizes the deterioration of soil, water and ecosystem
by promoting carbon sequestration, reducing nutrient
losses to ground and surface water bodies and to
atmosphere. 9
Advantages of Integrated Nutrient management
10. Common constraints encountered by the
farmers in adoption of INM technology are
as follows :
10
1. Lack of knowledge and poor advisory services.
2. Difficulties in growing green manuring crops.
3. Non-availability of FYM and composts.
4. Non-availability of soil testing facilities.
5. Non-availability of Bio-fertilizers.
6. High cost of chemical fertilizers.
7. Non-availability of improved seeds.
11. Mulching
Definition:
Mulch is a material placed on the soil surface to
maintain Soil moisture, reduce weed growth,
mitigate soil erosion and improve soil
conditions. Mulching is one of the simplest and
beneficial practices for soil and moisture
conservation. 11
13. Mulching improves the soil structure and increases the
infiltration-capacity of the soil.
Protects soil from erosion.
Conserve moisture in soil thus saving the need for
frequent irrigation.
Maintains a more even soil temperature.
Prevents weed growth to check loss of soil nutrients.
Crop residues act as a mulch and reduces soil
evaporation.
Sorghum stalk spread over 40 cm depth with 15 cm wide
in the beds increased 20-30% crop yield .
Coir waste can hold water five times as of its own weight.
It enriches soil by adding organic matter and reduces
weed infestation.

36. Conclusion
The application of chemical fertilizer in combination
with organic manures and biofertilizers is the most
suitable INM module/practice for mustard crop.
Apply of 75% NPK+N-25%(FYM)+S@40kg+mulching
@5 t/ha are reported that the highest seed yield
(22.08q/ha), stover yield (51.43q/ha), H.I (30.87%),
Gross return (Rs.92835), Net return (Rs.52309) and B:C
ratio 1.29 (Diwakar et al.,2021).
