THEME
    Factors to consider in Managing Large Scale Plantations

    Size of Manageable Plantation

  1. 10,000 Hectares (100 square Km)

  2. 5,000 Hectares (50 Square Km)

  3. 2,500 Hectares (25 square Km)

  4. 1,000 Hectares (10 square Km)

Divide large plantations into segments of 2,500 hectares.

    2,500 Hectare Plantation
  1. Boundary of Area

  2. Contours of Area

  3. Water Bodies

  4. Clearing the area

  5. Internal Roads

  6. Housing, food, water, electricity for labour

  7. Transport of labour and goods

  8. Nursery and Plantation

  9. Pruning and Maintenance

  10. Harvesting

    Boundary of Area
    Plot may be
  1. Square easier to manage

  2. Rectangular longer roads

  3. Irregular difficult to map

  4. Sloping better for water drainage and irrigation

  5. Rocky Patches useful for housing / storage sheds

    Contours of Area
  1. Mapping to be done

  2. Some leveling required

  3. Make water channels

  4. Create localized water bodies

  5. Difficult to use machines on sloping lands

    Water Bodies
  1. Use water from existing rivers

  2. Quality of water

  3. Create ponds / percolation tanks

  4. Sink Tube wells

  5. Sprinkling network

  6. Pumps and pumping cost

    Clearing the area
  1. Leave large trees

  2. Cut small bushes above ground

  3. Mulch cut bushes into soil

  4. Mix farm yard manure (FYM)

  5. Level the ground

  6. Do not burn the bushes

  7. Do not disturb organic system

    Internal Roads
  1. Use existing roads

  2. Main road every Km

  3. Create feeder roads every 200 meters

  4. Should be suitable for tractors, trucks

  5. Should not be steep

  6. Support sheds along roads

  7. Water channels should be away from road

    Housing, food, water, electricity
  1. Housing close to main road

  2. Relocatable houses

  3. Preferably on sloping or rocky land

  4. Water through tube wells

  5. Disposal of effluent

  6. Food supply through mobile kitchens

  7. Mobile electric supply units

    Transport of labour and goods
  1. Preferably in trucks

  2. Labour from camps to farm

  3. Product from farm to storage

  4. Distributed storage bins for seeds

  5. Central collection system

  6. Managers, supervisors for every 2,500 hectares

    Nursery
  1. One for every 2,500 hectares

  2. Nursery size will be 25 hectares

  3. Jatropha seeds required will be 15 tons

  4. Organic fertilizer required will be 15 tons

  5. Water required 25,000 cubic meters per month for 3 months

    Nursery Manpower
    Man hours per hectare of Plantation
  1. Mixing of Manure / Seeds Sowing : 50

  2. Mixing of Fertilizer / Application : 10

  3. Nursery Raising : 12

  4. Transport of plants : 3

  5. Total : (75)

    Plantation
    2 X 2 meters for manual plantation
    3 X 2 meters for mechanized plantation
    Man hours per hectare of Plantation
  1. Digging of Pits : 250

  2. Planting : 200

  3. Misc : 10

  4. Total : (460)
    Digging time can be reduced by using Post Hole Diggers attached to tractors
