3. INTRODUCTION
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
Integrated nutrient management (INM) involves efficient and
judicious use of all the major components of plant nutrient
sources for sustaining soil fertility, health and productivity
Integrated approach for plant nutrition is being advocated
because single nutrient approach often reduces fertilizer use
efficiency and consequently creates problem fertilizers can
help in enhancing and maintaining stability in production with
least degradation in chemical and physical properties of the
soil.
4. A healthy soil is a living, dynamic ecosystem that performs
many vital functions.
A healthy soil produces a healthy feed for consumption.
Improved soil health often is indicated by improvement on
physical, chemical and microbiological environment.
Introduction of high yielding varieties, irrigation and use of
high analysis fertilizer without proper soil tests, accelerated the
mining of native soil nutrient resources.
Under intensive cultivation without giving due consideration
to nutrient requirement has resulted in decline in soil fertility
and consequent productivity of crops
Vegetables are rich source of energy and nutrition.
5. It is known that in several parts of India, there are nutrient
deficiencies of N, P, K, S, and the micronutrients like Zn, Mn,
Fe and B in one or the other vegetable crops. Therefore, to
sustain or increase productivity of vegetable crops
management of nutritional disorders is of paramount
importance
Increase in vegetable production has to come primarily from
land saving technologies such as use of high yielding input
responsive varieties, better nutrient management preferably
through integrated nutrient management (INM), use of modern
methods of irrigation etc. Now-a-days the role of organic
manures in vegetable production is being increasingly
recognized
6. NEED FOR ENHANCED VEGETABLE CROP PRODUCTION
Our population is growing @ 1.13 % per year and at
this rate of population growth will be over 1.35
billion in 2020.(source – www.worldpopulationreview.com)
To meet the full dietary need of the common person, and to
relieve our stress on cereals, there is greater need of enhanced
vegetable production.
Upto 2020 the country’s vegetable demand would be around
135 million tonnes.(source – www.indiafoodsecurityportal.org)
To achieve target, it is important to integrate the various
technologies right from production to harvest in vegetable
production.
7. INM in relation to soil properties
The increasing use of chemical fertilizers to increase the
production of food and fibre is causing concern for the
following reasons :
• Soils which receive plant nutrients only through chemical
fertilizers are showing declining productivity despite being
supplied with sufficient nutrients.
• The decline in productivity can be attributed to the
appearance of deficiency in Secondary and micronutrients.
• The physical condition of the soil is deteriorated as a result
of long-term use of chemical fertilizers, especially the
nitrogenous ones. It also aggravates the problem of poor
fertilizer nitrogen use efficiency (NUE).
• Excess nitrogen use leads to groundwater and
environmental pollution apart from destroying the ozone
layer through nitrous oxide production.
8. Goals of INM
• To maintain soil productivity
• To ensure productivity and sustainable agriculture
• To reduce expenditure and cost of purchased inputs by using
farm manure and crops residues etc.
• To utilize the potential benefits of green manures, leguminous
crops and biofertilizers.
• To prevent degradation of the environment.
9. Advantages of INM
• Enhances the availability of applied as well as native nutrients.
• Provides balanced nutrition to the crops.
• Minimizes the antagonistic effects resulting from hidden
deficiencies and nutrient imbalance.
• Improves and sustains the physical, chemical and biological
properties of soil.
• Minimizes the deterioration of soil, water and ecosystem by
promoting carbon sequestration.
10. Disadvantages of INM
• Non availability of FYM, biofertilizers, soil testing facilities and
water.
• High cost of chemical fertilizers.
• Difficulties in growing green manure crops.
• Lack of knowledge and poor advisory services
• Non availability of improved seeds and credit facilities.

COMPONENTS OF INM
12.
13. Manures
Manures are the organic materials which improve soil
fertility when incorporate into the soil.
They are made up of animal remains and dead plants
and contain more than one nutrient element.
Concentration of nutrient in organic manure is low as
compared to chemical fertilizers.
Fertilizers
It is a chemical substance which is manufactured
artificially.
Fertilizer is rich source of nutrient and applied crop
protection to supply a particular nutrient in which
soil is deficient.
14. Advantages of manure
They improve soil physical properties like
structure, water holding capacity, etc,.
To increase nutrient availability.
They prevent the loss of nutrients by leaching or
erosion.
Manures supply plant nutrients including
micronutrients.
15. Benefits of green manuring
• Fit well in fallow period of 50-70 days.
• No extra land preparation.
• Improves soil organic matter.
• Increase the moister in soil
• Maintain the soil pH.
• Improve water holding capacity of soil.
16. Biofertilizers
• Biofertilizers are organisms which can bring about
enrichment of soil nutrients either by fixing
atmospheric nitrogen or by increasing the solubility
and availability of other nutrients, particularly
phosphate.
• The main source of Biofertilizers are Bacteria
(Rhizobium,Azospirillum), Fungi (Mycorrhiza),
Cynobacteria Anabaenas,
17. Classification of Biofertilizers
I) For Nitrogen
Rhizobium for legume crops.
Azotobacter l Azospirillum for non legume crops.
Acetobacter for sugarcane and sugarbeet.
Blue -Green Algae (BGA) and Azolla for low landpaddy.
2) For Phosphorous
with Rhizobium,Phosphatika for all crops to be applied
Azotobacter,
VAM(Vesicular - arbuscular mycorrhiza).
3) For Enriched Compost
Cellulolytic fungal culture.
Phosphotika and Azotobacter culture
18. Benefits of biofertilizer
• They are biodegradable.
• They do not Pollute soil and water resources.
• They are less expensive.
• Increase the grain yields by 10-40%.
• Improve texture, structure and water holding capacity
of soil.
• No adverse effect on plant growth and soil fertility.
• Replace 25-30% chemical fertilizers.

40. Conclusion
The combine use of organic and inorganic nutrients which lead to increased
uptake of NPK & Nutrient use efficiency.
INM help to maintain productivity, profitability & quality of vegetables.
Using poultry manure with inorganic source of fertilizer results maximum
vegetable production.
By using 25% RDF along with 75% neem cake considerably increase the
vegetative growth, yield and quality of brinjal fruit.
Application of 50% NPK + 50% FYM found best treatment in capsicum which
produced higher fruit yield.
In interaction of inorganic and organic manure, 150:120:60 kg/ha NPK with
FYM 40 t/ha were found superior in vitamin-C and chlorophyll content in
sweet pepper.
Use of vermicompost along with organic booster with a fermented mixture of
cow dung urine slurry (CDUS) is better for enhancing the yield of chilli crop
considerably.
Use of 50% RDF with 2.5 t/ha vermicompost and 2 spray of vermiwash found
superior in chilli cultivation.
The combined application of organic and chemical fertilizers with bacterial
41. By addition of FYM and VC there is enhancement of nutrient availability (NPK)
which ultimately enhanced microbial activity.
The balanced fertilization i.e., 100% NPK + FYM and biofertilizers enhanced the
bacterial count in the soil.
The integrated application of 50% NPK + 50% FYM + biofertilizers found
optimum for getting maximum productivity of carrot without reducing fertility
status of soil.
Application of organic manures such as FYM, vermicompost, crop residues
enhanced the soil available nitrogen, phosphorous and potassium as compared
to recommended dose of fertilizers
The application of 50% NPK + 15 mt/ha vermicompost in tomato found more
available NPK nutrient status in soil.
In cabbage an increase in organic carbon status of soil in vermicompost + RDN
along with biofertilizers treated plot is mainly due to increase in total microbial
population.
