5. Why do farmers raise seedlings in nursery?
Farmers raise seedlings in nursery because of
the proper caring and nourishment that can be
easily given to the plants and the seedlings in
nursery. In a nursery, there are trained
professionals who keep an eye on the growth of
the plant's seedlings.
6. The key elements of nursery management:
Think before you start the nursery
Planning structures and flow of work
Planning crops and developing propagation
protocols
Three phases of crop development
Propagation environments
Media for raising nursery
Use of containers
7. A plant nursery is a place where any kinds
of plants are grown for the sake of being
moved or transplanted later.
It can occupy a field, garden, greenhouse,
or other form of growing space.
8. 1) The place;
2) The plant;
3) The person behind.
The place:
Selection of site:
In our country, less emphasis is given
on selection of site for the nursery.
An unsatisfactory site will increase the
cost of operation and poor stock
production.
9. • The nursery lay out should be compact and in rectangular or
square shape
• Wind break/ shelter break must be done all along the
boundary not only to protect against hot wind and wild life
but also to modify the micro-climatic situations.
• The nursery should be connected by main road for better
approach and disposal of produce.
• There should be proper provision for road and path,
irrigation and drainage channels, mother block, nursery
beds, growing structure, store, compost pit, etc.
10. The plant:
Plant types and propagation
Though, the availability of stock (seeds or mother plant) of
recent released varieties are low at initial stage, by
multiplying them even at smaller quantity, one can earn a
better price in the market.
The soil of seedbed should be worked well to break the clods.
The weeds, stones and stubbles should be removed.
Two parts of fine soil, one part of FYM can be incorporated to
each bed to improve aeration and fertility of the soil.
Production of quality planting materials is another factor, which
not only decides the establishment of plants in the field but also
useful in handling and transportation and ultimately earning of
better returns.
11. The person behind
• The ultimate success depends
upon the person who is dealing
the whole affairs of nursery
management.
• The nursery manager must
understand the dynamics of
business terrain.
• He should always keep in touch
with the organizations working
on nursery management to
understand the innovations
made in recent past.
12. Think further on financial aspects like:
•How much money can be invested in the
nursery at the outset?
•The labor force that can be hired.
•In what timeframe the nursery can start to
produce plants for sale
•What price can be charged for the plant
materials?
•How many plants can be produced? What
price can be charged for the plant
13. • Cucumbers-aged 20-23 days, presence
of two or three leaves.
• Tomatoes -at least 45 days, from 6
real leaves and, if possible, a flower
brush.
• Peppers -at least 70 days, 8 leaves and
25 cm in height, flower buds.
• Eggplant -about 50 days, 6-7 leaves.
14. Calculation of seedling needs:
Calculation of seedling needs should be done
based on the following:
Area to be planted
Planting scheme
15. X =10000 / (A x M)
Number of seedlings per 1 ha:
Ordinary way
M- distance between rows
A-distance between plants in a row
X =(100/L+M)∗N∗(100/A)
Distanced rows with 2 or 4 lines
M- distance between lines in a row
A-distance between plants in a line
N-number of lines in a row
L-width of row
16. Tray number (PCs)= number of seedlings
(PCs)/number of slots in cassette
Quantity of substrate (l)= volume of housing
(cm3) x number of housing / 1000
