Project 1: Plant Nursery (Part 1: Work with Life Forms)

About the Project

In Project 1: Plant Nursery you will set up a small plant nursery in your school and learn how new plants are raised. Plants propagate (reproduce themselves) in different ways — tiny seeds germinate and grow into trees or flowering plants, while some plants grow directly from branches of the mother plant or from tubers (e.g., potatoes).

Plants need air, sunlight, nutrients and water, but they also need a favourable environment — the right humidity and an optimal temperature. That is why more plants grow near streams, ponds, wells and taps: they get the right temperature, humidity and soil moisture. In a nursery, you create these conditions on purpose.

A plant nursery lets us grow plants whenever required, not only in the seasons usually suitable for them.

Nurseries are important for preserving original plant species, creating new varieties, and producing plants on a large scale. Because a nursery is smaller than a farm, it is easier to prevent pests and protect plants from heavy rain or severe heat.

Did you know? Thimmamma Marimanu, a banyan tree in Ananthapuramu district of Andhra Pradesh, is spread over 5 acres — the size of a small village — all from a single seed!

What You Will Learn

By the end of the project you will be able to:

  • Describe the needs of germinating seeds and young plants.
  • Cultivate new plants using different plant propagation methods.
  • Provide suitable conditions for the initial growth of plants.
  • Develop a plant nursery in the school.

    • Materials & Tools

  • Gardening tools: garden shovel, spade, hand cultivator, grafting knife, pruning shears (secateurs) or a sharp cutter, watering can, gardening gloves.
  • Nursery materials: seedling (plug) tray, cocopeat, sphagnum moss or coco husk, compost or manure, seed germination paper or cardboard (45 cm × 28 cm).
  • Other materials: shade-net, bamboo or wooden poles (8 ft), PVC pipe, tarpaulin sheet, bricks, measuring tape, plant labels, first-aid kit, lime powder, geometry scale, pencil, rubber bands, plastic tray and water.

    • Step-by-Step Activities

    Activity 1: Visit a nearby plant nursery

    Observe how air, sunlight, water, humidity, temperature and nutrition are maintained. Record the date, nursery name, type of nursery (vegetable, fruit, flowering, ornamental), plants grown, tools used and management practices (watering, pest control, nutrients). Ask the experts how they give the right sunlight and shade, keep the right temperature, water and humidity, protect plants from pests and animals, and transport plants. If there is no nursery nearby, invite a farmer or gardener to school.

  • In agricultural areas you find nurseries for vegetables (brinjal, tomato, onion) and crops like banana.
  • In urban areas, nurseries sell ornamental and flowering plants (rose, marigold).
  • In coastal and hilly areas, horticultural nurseries grow plants like mango and coconut.

    • Activity 2: Planning and laying out the nursery

  • Choose a place that gets at least 2–3 hours of sunlight and where waterlogging can be avoided.
  • About 150–200 square feet is enough. No land? Use an unused space, pathway, parking lot — or grow the nursery in pots.
  • Draw a layout with dimensions showing pathways, water source and beds.

    • Activity 3: Preparing land and setting up the shade-net

  • Clean the area — remove unwanted plants, debris and rocks.
  • Mark the boundary with lime powder, along with pathways and beds.
  • Fix a green shade-net on bamboo or wooden poles.
  • Choose shading of 50% or 75% based on plant needs. No shade-net? Use tree branches or old sarees. On a terrace, fix poles in tin boxes or drums filled with sand.
  • Make a protective fence from discarded pipes, bamboo or fallen branches to keep out animals and people.

    • The shade-net protects young plants from excessive heat and heat stress.

    Activity 4: Germinating seeds — the germination test

    Not all seeds germinate. The seed germination rate tells you how many seeds are likely to become plants, so you know how many seeds to sow.

  • Mark 3 × 3 cm squares on seed germination paper (or cardboard).
  • Soak the paper in water and let extra water drain.
  • Count 100 seeds and place them at equal distances.
  • Roll the paper gently, put rubber bands on it and keep it for 3–5 days.
  • Count the germinated seeds.
  • Calculate the germination percentage:
    • Germination % = (Number of seeds germinated ÷ Total seeds tested) × 100

    Example: if 85 out of 100 seeds sprout, the germination rate is 85%. Seed-packet labels also mention the germination rate.

    Activity 5: Raising plants in the nursery

    Seeds and cuttings contain reserve food (carbohydrates, protein, vitamins, nutrients) used during germination. Always sow more seeds than the number of plants you want.

    Method 1 – Raised-bed nursery

  • Dig and loosen soil; remove stones and pebbles.
  • Mix compost and soil in about 40:60, and raise the bed 15–20 cm above ground.
  • Bed length 3–5 m, width 1–1.5 m; keep 0.30–0.40 m between beds for walking, watering and weeding.
  • Raised beds let extra water drain and give roots air for respiration.
  • Mix very small seeds with fine sand or soil, sow gently, cover with soil and water with a watering can.

    • Method 2 – Plug or seedling trays

  • Useful when space is limited or for large-scale seedling production.
  • Soak cocopeat — 1 kg cocopeat absorbs 5–8 litres of water.
  • Fill trays gently, sow 1–2 seeds per hole, cover with tarpaulin or gunny bags for 2–3 days.
  • Once seeds germinate, move trays into the shade-net nursery.
  • No trays? Use coconut shells, old teacups or similar waste.
  • Growing media (cocopeat, vermiculite, bentonite) manage moisture better, help avoid disease and provide nutrients.

    • Method 3 – Stem cuttings

  • Use nursery bags (5 × 4 inches) or old 500 ml milk pouches; make 2–3 drainage holes; fill with 2 parts soil + 1 part compost.
  • Take a stem from a healthy parent plant, make a slant cut (45°) at the base for more rooting surface. The cutting should be 4–6 inches long with at least 2–3 nodes.
  • Dip the cut end in rooting hormone powder or gel.
  • After proper shooting (30–45 days), shift the plant to a bigger polybag or the field.

    • Types of stem cuttings:

  • Softwood (10–15 cm, keep top 2–3 leaves): citrus, cherry, apple, peach; herbaceous: coleus, chrysanthemum, dahlia, tulsi, carnation. Also duranta, alternanthera.
  • Semi-hardwood (partly mature shoots): mango, guava, lemon, jackfruit, roses; also dieffenbachia, croton.
  • Hardwood (mature, woody, dormant season): grape, fig, mulberry, pomegranate; also rose, bougainvillea.

    • Did you know? Rahibai Soma Popere, the 'Seed Mother of India' and recipient of Padma Shri and Nari Shakti Puraskar, conserved more than 43 indigenous crop varieties in a seed bank at home.

    Activity 6: Watching plants grow

    Keep a record of each plant: nursery method, quantity of seeds or cuttings, date of planting, date of germination/first leaf, and observations. Apps for plant watering reminders, pest identification and timelapse photos can help. Care for young plants until they are ready for transplantation in the right season and place.

    Activity 7: Calculating the cost

    List unit cost, quantity and total price for every item — e.g., tomato seed at ₹10 per g × 5 g = ₹50. This helps decide a selling price for your plants.

    Safety First

  • Use the right tool for the job; handle heavy tools (spades, shovels, pickaxes) and sharp tools (cutters, knives) carefully.
  • Wear well-fitting gloves for a good grip.
  • Ask for help if unsure about a tool.
  • Wash hands after working with soil — it may contain disease-causing micro-organisms.
  • Lift correctly — bend your knees, not your back.
  • Store tools on racks or in marked places.
  • Internet safety: take your teacher's help; don't share personal information.

    • Key Terms

  • Propagation (प्रवर्धन) — producing new plants from seeds, stems or tubers.
  • Germination (अंकुरण) — a seed sprouting into a seedling.
  • Germination rate (अंकुरण दर) — percentage of seeds that sprout.
  • Humidity (आर्द्रता) — amount of water vapour in the air.
  • Optimal temperature (अनुकूल तापमान) — the best temperature for growth.
  • Shade-net (छाया जाल) — net that cuts sunlight to protect young plants.
  • Raised bed (उठी हुई क्यारी) — bed raised 15–20 cm for drainage.
  • Seedling / plug tray (पौध ट्रे) — tray with small cells for seedlings.
  • Cocopeat (नारियल का बुरादा) — growing medium from coconut husk.
  • Stem cutting (तना कलम) — part of a stem used to grow a new plant.
  • Node (गाँठ) — point on a stem where leaves grow.
  • Rooting hormone (जड़ वृद्धि हार्मोन) — helps cuttings form roots.
  • Transplantation (रोपाई) — moving a young plant to its final place.
  • Waterlogging (जलभराव) — excess water collecting in soil.

    • Think and Answer — Hints

  • What did you enjoy / what challenges did you face? Mention a specific activity (germination test, cuttings) and a real problem (e.g., seeds not sprouting, pests).
  • What will you do differently? Use your germination rate to sow the right number of seeds; choose better shade.
  • Why is a plant nursery important? Preserving species, new varieties, large-scale production, off-season growing, easier pest control.
  • What else can I do? Decorate pots as gifts, run a plantation drive on Independence or Republic Day, grow seasonal plants.

    • Career & Community Connections

    The book suggests jobs linked to this project: gardener, botanist, forest officer, farmer, agriculture scientist. Nursery owners and horticulturists also use these skills.

    Common Mistakes

  • Choosing a spot that gets waterlogged or has less than 2–3 hours of sunlight.
  • Sowing exactly as many seeds as plants needed, ignoring the germination rate.
  • Making a straight cut instead of a 45° slant cut, or taking cuttings with fewer than 2–3 nodes.
  • Forgetting drainage holes in nursery bags.
  • Keeping trays covered after seeds sprout instead of moving them to the shade-net.
  • Not washing hands after handling soil.

    • 💡 Key Learning Points

    • ✓Plants need air, sunlight, water and nutrients plus suitable humidity and optimal temperature to grow.
    • ✓A nursery site needs at least 2–3 hours of sunlight, no waterlogging and about 150–200 sq ft; a 50% or 75% shade-net protects young plants from heat stress.
    • ✓The germination test (100 seeds on marked, moist paper for 3–5 days) gives the germination rate = (germinated ÷ total) × 100, which tells us how many seeds to sow.
    • ✓Three propagation methods: raised beds (compost:soil ≈ 40:60, 15–20 cm high), seedling trays with cocopeat, and stem cuttings (45° slant cut, 2–3 nodes, rooting hormone).
    • ✓Keeping records and calculating costs helps plan care, transplantation and a fair selling price.

    👨‍🏫 Teaching Tips

    • →Begin with a nursery visit or invite a local gardener/farmer; give students the book's question list to interview them.
    • →Let groups measure and mark the site with lime powder themselves and draw a scaled layout.
    • →Run the germination test with 100 seeds per group and compare germination percentages across seed types.
    • →Demonstrate the 45° slant cut and node counting on a real rose or tulsi stem before students try.
    • →Set up all three sowing methods side by side so students can compare growth.
    • →Assign rotating duties (watering, weeding, record keeping) and maintain a class growth register.
    • →Use a real tomato seed packet to show germination rate on the label and practise the cost table.
    • →Plan a plantation drive or Kaushal Mela sale with the saplings raised.
