THEME
Factors to consider in Managing Large Scale Plantations
Size of Manageable Plantation
10,000 Hectares (100 square Km)
5,000 Hectares (50 Square Km)
2,500 Hectares (25 square Km)
1,000 Hectares (10 square Km)
Divide large plantations into segments of 2,500 hectares.
2,500 Hectare Plantation
Boundary of Area
Contours of Area
Water Bodies
Clearing the area
Internal Roads
Housing, food, water, electricity for labour
Transport of labour and goods
Nursery and Plantation
Pruning and Maintenance
Harvesting
Boundary of Area
Plot may be
Square – easier to manage
Rectangular – longer roads
Irregular – difficult to map
Sloping – better for water drainage and irrigation
Rocky Patches – useful for housing / storage sheds
Contours of Area
Mapping to be done
Some leveling required
Make water channels
Create localized water bodies
Difficult to use machines on sloping lands
Water Bodies
Use water from existing rivers
Quality of water
Create ponds / percolation tanks
Sink Tube wells
Sprinkling network
Pumps and pumping cost
Clearing the area
Leave large trees
Cut small bushes above ground
Mulch cut bushes into soil
Mix farm yard manure (FYM)
Level the ground
Do not burn the bushes
Do not disturb organic system
Internal Roads
Use existing roads
Main road every Km
Create feeder roads every 200 meters
Should be suitable for tractors, trucks
Should not be steep
Support sheds along roads
Water channels should be away from road
Housing, food, water, electricity
Housing close to main road
Relocatable houses
Preferably on sloping or rocky land
Water through tube wells
Disposal of effluent
Food supply through mobile kitchens
Mobile electric supply units
Transport of labour and goods
Preferably in trucks
Labour from camps to farm
Product from farm to storage
Distributed storage bins for seeds
Central collection system
Managers, supervisors for every 2,500 hectares
Nursery
One for every 2,500 hectares
Nursery size will be 25 hectares
Jatropha seeds required will be 15 tons
Organic fertilizer required will be 15 tons
Water required 25,000 cubic meters per month for 3 months
Nursery Manpower
Man hours per hectare of Plantation
Mixing of Manure / Seeds Sowing : 50
Mixing of Fertilizer / Application : 10
Nursery Raising : 12
Transport of plants : 3
Total : (75)
Plantation
2 X 2 meters for manual plantation
3 X 2 meters for mechanized plantation
Man hours per hectare of Plantation
Digging of Pits : 250
Planting : 200
Misc : 10
Total : (460)
Digging time can be reduced by using Post Hole Diggers attached to tractors
