• Nursery


  A managed site, designed to produce seedlings grown under favorable conditions until they are ready for planting

  
• What a nursery is

  • Plants are grown
  • Nurtured
  • Sold out
• Plant growers require good quality seedling / sapling of true type

  
• Types of nursery based on duration

  • Temporary nursery
  • Permanent nursery
• Types of nursery based on plants produced

  • Ornamental nursery
  • Vegetable nursery
  • Fruit plant nursery
  • Forest nursery
• Types of nursery based on structure used


  • Open field nursery
  • Hi-tech nursery (Thatched roof
  • Shade-net
  • Poly-tunnel
  • Greenhouse or poly-house)
• Types of nursery based on arrangement

  • Raised bed
  • Flat bed
  • Sunken bed
• Importance of nursery


  • Possible to provide favourable growth conditions
  • Better care of younger plants
  • Saving of land and labour
  • Allows additional time for doing land preparation
  • Seed requirement of nursery raised crops is less as compared to direct seed sowing
  • Possible to grow and maintain a large number of plants per unit area
  • Can increase germination percentage and the vigour of the seedlings
  • Manipulation of growing conditions for plants become easy
  • Better and uniform crop growth can be obtained in the main field

  
• Factors to consider when selecting a nursery site

  • Location
  • Topography of land
  • Soil and climate
  • Water
  • Drainage
  • Transportation
  • Labour
  • Protection from animals
  • Market needs and size
• Components of a nursery

  • Fence
  • Road and paths
  • Progeny block/Mother block
  • Nursery office, store
  • Sales area
  • Seed bed
  • Nursery bed
  • Potting mixture and potting yard
  • Compost pit
  • Propagation area
  • Media preparation and storage
  • Production areas
  • Packing shed
  • Propagation structure
  • Service area
  • Wind break
• Nursery layout
• Good nursery practices


  • Pricking Out
  • Shading
  • Watering (Seedling age, Amount of sunlight, Soil type)
  • Weeding
  • Application of fertilizers
  • Root pruning
  • Hardening off

  
• Common possible errors in a nursery

  • Containers not filled properly
  • Container not in upright position
  • Soil or sand used in germination beds not changed after each production cycle
  • Sowing seed too deep
  • Lifting transplant seedlings individually and wrenching them
  • Exposure of seedlings to air after lifting
  • Bad transplanting and delayed transplant to container beds
  • Leaving air space around the root of the young seedling after transplanting
  • Bad root pruning while transplanting
  • Hardening off process starting too late or neglected

• Land preparation


  1. Ploughing

  2. Leveling
• Ploughing


  • Process of loosening and turning of soil
  • Allows the roots to penetrate deeper easily
  • Soil is overturned and properly aerated
• Traditional & Modern ploughing

  • Laser aided land leveling
• Sowing / Planting


  1. Broadcasting

  2. Seed drill

  3. Direct seeding

  4. Transplanting
• Manuring


  Feed the plants with nutrients
• Three Rs of manuring

  • Right material
  • Right time
  • Right amount
• Manure and fertilizers


  Natural and chemical compounds that supplement plant nutrients
• Irrigation


  1. Farrow

  2. Drip

  3. Sprinkler

  4. Basin
