Title: Integrated nutrient management in mango


1
Organic manures as a component of INM in Mango


Organic manures are important for maintaining
soil health by enhancing the biological cycles
and improving yield and quality of mango fruits.
It is advisable to apply 1/3rd required quantity
of nutrients through organic manure and rest
thorough inorganic fertilizers for getting
maximum return without damaging soil health.
Manuring in mango plant should be starts right
from planting operation in the orchard. Well
decomposed organic manure can be given each year
to create proper soil physical environment and to
avoid the infestation of harmful pests like
termite.

Therefore, knowledge of source, time and methods
of organic manures is very important for getting
maximum benefit of organic manure in mango.

Hence in this RLO you will learn the sources and
nutrients content in different organic manure and
time and methods of application.
3

Objective
After completing this lesson, you will be able to

Explain the different sources, doses, time and
methods of application of organic manure in mango.

Doses of organic manure

Age of the plant (year) Organic manure (kg/tree)
1 10.00
2 10.00
3 15.00
4 20.00
5 25.00
6 30.00
7 35.00
10 50.00
5
Time of application

At time of planting Pit should be filled with
20 kg FYM 5 kg vermi compost with top soil.
In bearing and non bearing orchards, apply full
quantity of organic manures in October with last
irrigation.
6
Application method

In addition to source of nutrients, time of
application and doses, the method of manure
application is also important in nutrient
management.
Organic manure like FYM, vermi compost, Nadep etc
must be equally distributed on the root zone
area from 30 cm tree trunk to drip line in mango
trees.
7
Application method
After broad casting, organic manure should be
incorporated thoroughly to the soil by
cultivating the top soil.
Care should be taken not to damage the roots.
After manure application, trees must be irrigated
immediately.

Source and nutrient content in different manures

Manure N P K Ca Mg S
Cattle 1.5 1.5 1.2 1.1 0.3
Poultry Broiler litter Hen-litter 3.0 1.8 3.0 2.8 2.0 1.4 1.8 0.4 0.3
Sheep manure 0.6 0.3 0.2
Sewage sludge 5.0 6.0 0.5 3.0 1.0 1.0

General suggestions
Depending upon the soil conditions, availability
of the forms and source, organic manure should be
decided.

For full growing mango trees, application of 40
kg FYM and 250 g culture of azosprillum should be
applied just after harvesting.
