4. Nursery site selection (flat land, near water perennial sources)
• Number of plants to be produced each year
• Species to be selected
• Type and size of plants
• Location of the plantations and villages where plants are supplied
• Expected life of the nursery
The ideal nursery location should fulfil the following requirements:
• Land availability
• Good permanent water supply or piped water system.
• Good drainage with gentle slope
• Easy accessibility with road communication
• Good supply of suitable soil materials
• No chance of flooding
• Not prone to erosion
6. Basic facilities:
• Entry gate
• Internal paths
• Fence or wall
• Office room
• Storage room
• Labour shed
• Vehicle shed
• Drinking water facility
• Toilet
Infrastructures to produce seedlings:
• Mother beds
• Seedbeds
• Poly house
• Hardening shed
• Drying shed
• Water tanks
• Water distribution system
• Drainage system
• Soil storage shelter
• Compost-making area
• Seed treatment pit
• Research area(Room)
7. Construction
Land preparation
cleared of all rocks, stumps, trees and shrubs
desirable to plough or hoe the soil in the winter and allow it to weather for some time.
The Nursery beds may be raised if the area is plain to ensure good drainage, in hill sides it may be a
little sunken to conserve moisture during heavy rain.
Fence or wall
brick wall 1.8m high is ideal
It should be about 60cm below ground and 120cm above,
A layer of thorny shrubs on top of it will be effective
A brick wall is effective and long lasting.
Nursery beds and other structures
Ideal size of the nursery bed is 1m to 1.2m wide and 15 cms high.
The typical length of the bed is 5m to 10m
the beds should be oriented from east to west
Paths should be 50cm to 60cm wide to provide adequate working space.
Nursery beds can be temporal or permanent
Permanent beds are made on the concrete floor
8. • Some important species do not seed every year. Plantations of these species can be raised
annually only by collecting all available seed in years of moderate and good seed years and
sowing it in nursery to raise seedlings to be planted out in various years.
• Some species grow very slowly and if the seed sown directly in plantation that can be
damaged and killed due to the competition of weeds. So, the slow growing species are
generally raised in nursery and planted out only when the seedlings are not liable to be
damaged by weeds.
• Success of roadside avenue plantations depends largely on planting tall and sturdy plants
which can only be obtained from a nursery.
• Seedling production at nursery is very essential to introduce exotic species (e.g. Tropical
Pines, Poplars, Eucalyptus) since planting is the only way.
• For barren site and poor regenerating area planting of nursery grown plants is the only
method of artificial regeneration.
• There is a wide scope for fruit orchards, ornamental, vegetable, and landscape gardens at
public places, highways and co-operative housing societies.
• Nursery provides employment opportunities for technical, skilled, semi-skilled, unskilled
Labour.
Importance of Nursery
9. Preparation of soil
• dry fine textured consistent soil may be prepared
• Collect topsoil, break clods, remove foreign materials, and mixsoil with sand
and farm yard manure (FYM) if required
• Generally,soil can be mixed with 2(soil):1(sand):1(manure).
• Preparation of mother beds
Prepare mother beds including breaking clods, removing foreign materials,
mixing sand with decomposed cow dung/ compost, and sow seeds and make
watering.
Soil solarisation: Solarisation is an effective and eco-friendly method of soil
sterilization and it involves trapping of solar heat and energy through polythene
covering. This raises the temperature to levels at which many soil-borne plant
pathogens will be killed or greatly weakened.
10. • Seed sowing:
• Small sized seeds: a thin layer of fine soil is spread evenly over the seeds
• Bigger sized seeds: a small straight furrow across the length of the bed may be made in the beds
with a light dibble or a wooden stick and the seeds sown in the furrows and covered up with soil.
Seeds may be sown directly into the bags during the sowing season i.e. February-June.
Azotobactor/Rhizobium(Nitrogen fixing bacteria) 4-5gm/poly bag and neem cake (organic manure) 5
gm/poly bag will yield good results.
Maintaining Moisture/Temperature of the Beds
To achieve this, the beds may be covered with transparent polythene sheets with its end weighed
down by small stones or clods of soil. This will prevent moisture loss through evaporation and increase
the temperature of the nursery beds. It is more practical to expose the beds to the Sun to water the beds
to maintain the correct moisture level in the nursery beds.
Timing of Sowing: depends on the spp
Pricking out:To get quality sized seedling (thumb size), the seed may be sown broadcasting in the mother
bed and when they have few leaves, some may be pricked out so that the remaining may be spaced at
about 3-4 cm apart. The pricked out seedling may be planted in polybag nursery.
Fertility of the nursery: normally fertile soil (not too fertile) would be best suited in the field
condition.
11. ELEMENT ROLE IN SEEDLING NUTRITION
N (Nitrogen) Essential part of chlorophyll and proteins; fosters vegetative growth.
P (Phosphorus) Promotes root growth and stem strength; important in all energy transfers within
plants
K (Potassium) Promotes starch and sugar formation, root
growth, resistance, shoot strength, and plant vigor.
Ca (Calcium) Enhances N uptake, cell elongation, and development of meristematic tissues
Mg (Magnesium) Major constituent of chlorophyll in plants; important in P metabolism and enzyme
activation.
S (Sulfur) Essential for synthesis of S-containing
amino acids and nitrogen fixation by legumes.
Fe (Iron) Important in chlorophyll production and enzyme activation.
Mn (Manganese) Activates enzymes regulating carbohydrate metabolism and essential for to chemical
(Hill)reaction.
Cu (Copper) Metal activator for several enzymes and possibly light reaction in plants
Zn (Zinc) Metal activator of enzymes.
B (Boron) Responsible for several regulator mechanisms in many plants, including sugar
translocation across cell membranes and oxidation processes.
Mo (Molybdenum) Required for N-fixation in legumes and ni- trate reduction in nonlegumes.
13. Filling Polybag with soil
Soil must be compacted by holding the fully filled bag and dropping it to the ground from 30 cm above the
ground without letting the soil spill out.
If the soil settles at a level less than the mouth of the bag, more soil may be added to make the soil almost
filling the bag fully.
The sown poly bags should be preferably kept in shade and the soil not allowed to becoming dry.
Watering the plants
Water should be sprayed in the beds preferably till root systems of the seedlings are well developed.
Beds should be moist rather than wet.
If beds are kept constantly moist, it may not require sheds.
The seeds are allowed to be germinated and grow up to about 3-5 cm and then pricked out and planted in
the poly bags and grown till it is fit for plantation in the field.
Weed control
Weed control in the nursery aims to minimize competition from weeds for light, water and nutrients.
Nursery can be weeded only when the root system of the seedlings has established properly.
Leaves of the mature seedlings may be plucked off to distribute sunlight to other smaller seedlings, so that
all seedlings attain equal size.
At the time of preparing nursery sites, the plant debris should be burnt thoroughly to increase the nutrient
level in the soil.
14. Hardening seedlings
• In order to survive for seedlings in a harsh environment in the field, seedlings are exposed to the rough treatment
called “Hardening”.
• The main treatment for hardening is the reduction of water with full exposure to sunlight withdrawing from the
favourable conditions in order to make seedlings to be more tolerant under such conditions.
• The hardening treatment should begin well in advance of the timing of transporting out.
• It should be not later than a halfway through the life of the seedling in the nursery.
• The process to reduce the amount and frequency of watering depends upon the species and local climatic
conditions; commonly reducing watering gradually to two or three applications per week.
Hardened seedlings have the several important characteristics of
1) firm, lignified stems, often brown in colour,
2) sturdy, well developed crowns with leaves extending over three quarters,
3) the length of the stem, and
4) vigorous, healthy, leathery leaves, compact rather than oversized and weak.
15. Nursery calendars: A nursery calendar to help plan
necessary actions and purchases of seed,supplies and
equipment.
Plant development registers: A plant development
register for collecting species-specific information
about seed treatment, germination requirements and
duration, plant development, special requirements for
potting substrate, watering, shading or disease control.
Nursery inventory: A nursery inventory to keep track of
the species and numbers of seedlings in different
stages of development.
Records of nursery experiments: A record of on-going
nursery experiments.
Nursery Journal to be maintained.
