Coffee Family - Rubiaceae Genus - Coffea Species - arabica and canephora Presentation By: Rajat Sharma
Brief History of Coffee Origin Coffee’s origin can be traced to the 12th century in Ethiopia, where it is believed to have been first harvested. “Traders brought coffee to the Middle East, from where it began to spread outward in the 15th century, penetrating every corner of Europe over the next two hundred years”. Coffee became a very important means of European trade as it spread to the Dutch’s, French’s, and British’s colonies during the 18th and 19th century. At this time, people from Africa and natives of the colonies were enslaved to work in the coffee plantations. “During the period of decolonization, coffee was put forward as a miracle crop that would allow developing countries to achieve economic growth.”

Soil and climatic requirement Soil: Coffee is not very specific with respect to its soil requirements. Important features of ideal soil for profitable coffee cultivation are Soil depth : It should be more than 75 cm Shallow or compact soil: Poor root development and spread. Roots develop only on upper horizons and it rarely goes deeper than 30 cm. Deep and permeable soil (>75 cm): Well developed tap root system, and rhizosphere occupy considerable soil volume. Soil PH: Slightly acidic to neutral pH is preferred ( PH of 4.50 to 6.00 and even upto 7.00)

Chandragiri coffee:  It is a newly released coffee in 2007-08 by Coffee Board with the original source from Portugal  It was introduced in the year 1975 to CCRI Balehonnur from Portugal. Farm trials and intensive research trials were taken up at CCRI Balehonnur.  Features:  1) Bushy growth with slightly bigger leaves than Cauvery coffee  2) Bigger sized berries: It produces 25 per cent bigger sized berries compared to other varieties.  3) Resistant to leaf rust: Lower (5 to 7 %) leaf rust incidence in this variety is reported compared to other varieties (20 to 40 %).  4) Tolerant to drought
Coffee Tree Growth Cycle  Dry and/or cool season – Floral initiation – Reduced vegetative growth  Wet season – Flowers open, fruit set and begin development – Active vegetative growth  Dry and/or cool season – Fruit ripen – Flower buds initiate – Reduced vegetative growth
Coffee Tree Growth Habit  Orthotropic stem – Erect growth  Plagiotropic stems – Horizontal secondary stems growing off of orthotropic stems – These are the fruiting wood
Growing Conditions  Grown under many conditions – Plantations – small farms – Under shade – In full sun – Monoculture – Mixed farming systems
Coffee Production  Planting – Slightly acid (pH 5.2 to 6.3) well drained soil – Beginning of wet season – Vertical position or 30° angle  Spacing - need light for fruit ripening – Arabica, 1350 trees/ha – Robusta, 900-1000 trees/ha  Time to fruiting – Take 3-4 years to obtain mature plant – Fruit on year old wood
Planting and aftercare  Site selection: The selected site should have following provisions;  Water supply : As perennial source  Soil rich in organic matter (humus)  Gentle Slope : Slope towards N or NE or E direction  Drainage : Provision should be there for adequate drainage  Altitude: Minimum of 500 m asl (Arabica 1000 m to 1500m while robusta 500 m to 1000m asl)  Wind break: Eastern wind during December- February causes injury to plants (cold injury). Hence, wind belts of silver oak or orange or tree coffee should be raised  Partial shade: Clear natural vegetation for providing required partial shade to coffee growth. It can be done by selective felling /retention of desired species of wild shade trees in the natural forest vegetation.
SPACING AND PLANTING: SPACING Plane land = square system of planting sloppy lands =Contour planting Steep slopes = Terrace planting Sl. No Type of Coffee ( species) Variety Spacing 1 Arabica Talls 6’ x 6’ or 7’ x 6’ or 7’ x 7’ 2 Arabica Dwarfs (Cauvery / Sanramon) 5’ x 5’ 3 Robusta Talls (S-274 and old robustas) S-1 R and S-2 R 10’ x10’ or 12’ x 12’ 4 Robusta C x R ( S-3R) 8’ x 8’ Other robustas viz., Old robusta and S-274 10’ x10’ or 12’ x 12’
Opening up of pits  Time: March-April (Immediately after the first few summer showers to give scope for weathering for about a month (at least 15 to 20 days))  Size of pit: Depending on soil depth /type 45 cm x 45 cm x 45 cm (LBD) - Always leave 15 –20 days for weathering.  Planting material selection for planting:  Seed propagation and  Vegetative propagation A) Seed propagation in coffee Preparation of seeds  Selection of berries: Only ripe berries are marked from marked coffee trees for seed collection and remove pulp and get beans.  Discard floats and defective beans  Seed treatment: Treat seeds with fungicide and dry seeds under shade.
B) Vegetative propagation: 1)Cuttings and 2) Grafting Propagation by cuttings:  Selection of shoots: Select orthotropic (vertical shoots) suckers from elite trees.  Age of shoot: Semihard wood and of about six months old. ( 3 to 6 months old shoots are better)
Shade and Coffee Production  Both species are understorey trees – Well adapted to shade – Initially coffee was planted under shade – Small holders may use mixed farming  Later unshaded plants were shown to produce higher yields
Shade and Coffee Production 0 1 2 3 4 5 6 7 8 Shaded Unshaded Fertilized No fertilizer Conclusion: High input system - better with fertilizer Low input system - not as essential
Coffee Production  Training/Pruning objectives – Maximize # plagiotrophic stems (fruiting wood) – Shape trees  Maximize use of space  Ease of management – Maintain open tree to allow good light penetration – Minimize biennial bearing – Remove diseased and dead wood
Types of training  Single stem training: Suitable under India conditions.  Multiple stem: Practiced in American and Latin American countries.  1) Single stem system:  Topping of growing main-stem  Purpose of topping/capping:  1) To restrict vertical growth and facilitating lateral branching giving increased fruiting area.  2) Thickening of main stem: It also helps in diversion of food material to thicken the main stem and primary branches.  As soon as the plant reaches a desirable height (first topping height) the growth of bush is restricted by topping/capping.
Raising of second tier:  Depending on the fertility of the soil and spreading of the plant when plants attain about 4.50 to 5 ft height (135 to 150 cm) the second tier is raised.
Table: First topping height in coffee Sl. No. Variety Topping height I - Tire (cm) Remarks II Tier height 1 Arabica Tall 60 to 75 ( 2.5 feet) In about 9-12 months stage after planting 4.50 to 5 ft 2 Arabica Dwarfs 90 to 135 ( 3 to 4.5 ft.) 3 Robusta 105 to 120 cm (3.50 to 4 ft) In about 18-24 months stage 4.50 to 5.00 ft
Single Stem Training (Central leader)  Cut back orthotropic stem – Encourages plagiotropic stem formation – Select one orthotropic as new leader  Repeat for 3-5 years – With each cycle the tree gets bigger – Lower limbs die due to lack of light  Rejuvenate after 3-5 years – To reduce size of tree – Cut back to 40-50 cm height
Single Stem Training (Central leader)
2) Multiple stem system (Agobiada system)  Countries: Practiced in African and Latin American countries. Here multiple stems are encouraged by bending the main stem ( i.e., Agobiada system  In India multiple stem training system is practiced under certain circumstances viz., Replanted fields: When old blocks are to be replanted with a new material, the old plants are stumped and converted into multiple stem to yield crops until the new plants come to bearing. High density planting: Here coffee is planted very closely in the initial years and later thinned out to normal spacing.  Here the plants which are to be thinned out ( removed or going plants) are raised on multiple stems for enabling the main plants to spread out their laterals.
Multiple Stem Training (Modified Central Leader)  Leave 2-8 orthotropic stems  Pruning – Cut out wood in center – Continues growing taller – Cropping area moves higher  Rejuvenation every 4-6 years – Need to lower fruiting surface – Allow basal suckers to grow

PRUNING IN COFFEE Benefits of pruning in coffee:  Yield regulation : Pruning reduces the risk of overbearing in any of the particular year.  Pest and disease incidence : By pruning there will be better entry of sunlight and air in to the bushes there by minimizing the incidence of pests and diseases.  Manageable shape : By proper pruning the tree is maintained in a manageable shape thereby improving the efficiency of field operations viz., spraying, swabbing, harvesting etc
Methods Of Pruning 1) Light pruning:  Time of pruning: Starts after the harvest of coffee ( December to February) and continues till the onset of monsoon. However, it is better to prune after few summer showers. Parts pruned during light pruning in coffee:  1) Old branches  2) Unproductive branches  3) Criss-cross branches  4) Dead and broaken/damaged branches  7) Disease and pest affected parts  8) Suckers II) Medium to severe pruning:  Periodicity of medium to severe pruning: It is done once in four years usually to replace the laterals.
Germinating Coffee Seeds Coffee Seedlings
Manuring in coffee Nutrition Management  Maintaining optimum pH by liming is essential requirement for nutrition management in coffee. If proper pH is not maintained, the applied fertilizers will not be utilised by the plants effectively.  Soil testing at least once in 2-3 years should be mandatory for lime and fertilizer applications.  Use agricultural lime analysing 80% calcium carbonate. November is the best period for lime application. Application of dolomite lime once in a while in rotation is beneficial.  Application of bulky organic manures like FYM or compost @ 5 tonnes/ha once in two years would improve the soil condition and better utilization of applied fertilizers.  The recommended dose of fertilizers should be applied in three splits (post-blossom, pre-monsoon, post-monsoon) by adopting drip circle method.

Shade management  Beneficial effects of shade in coffee – Quality improvement: Shade trees form natural canopy and it improves aromatic properties. – Improved foliar health: Shade helps in getting glassy elegant leaves and controls pre mature yellowing of leaves, defoliation and dieback. – Mulching effect: Leaves shed from the shade trees acts as soil mulch which in turn held in conserving the soil moisture and prevents soil erosion and improves soil organic matter status. – Temperature regulation: Insulation effect leading to buffering effect in soil temperature. – Improved organic matter status of soil : Decomposed leafy materials improves organic matter content of soil. There will be minimum loss of humus under shade thereby improving soil physical conditions. – Disease incidence : some of the diseases viz., Cercospora leaf spot and Colletotrichum etc are minimized under shaded situations – Yield regulations: Shaded situations prevents over bearing in any of the particular year and results in less variations / fluctuations in annual yields.

Harvesting and yield Hastening fruit ripening in coffee: Purpose: Speedy and uniform ripening will give scope for quick and early harvest = reduced cost of harvesting in coffee. Harvesting the berries: In India there is only one cropping season. Arabica coffee harvested from November to January and Robusta coffee from December to February. The crop will be ready for the first harvest in about 3 - 4 years but economic yields are obtained from 5 - 12 years onwards upto 50 years. The berries are harvested when they turn red to deep crimson colour. Season of harvest is from October to February. Harvesting is done in stages as follows;
Harvest  Most done by hand – Ripe berries only  Pick every 8-10 days – In Brazil, allow cherries to dry on tree  Machine harvest in Brazil
 Fly picking: Small scale picking of ripe berries from October - November to February.  Main picking: Well formed ripe berries are harvested in December.  Stripping: All left over berries irrespective of ripening are harvested after main picking.  Gleanings: Collection of fruits that have dropped down during harvesting.
Disease and Pests Problems  Losses due to diseases – Africa 15% – Asia 10% – S. Am. 12%  Coffee rust (Hemeleia vastatrix) – History  First in Sri Lanka in 1880  Now throughout world – Control  Robusta/hybrids resistant  Less serious above 1700 m  Cu fungicides  Coffee Berry Disease (Colletotrichum) – Cause berry rot
Disease and Pests Problems  Insert Fig 8.4, p 87  Losses due to pests – Africa 20% – Asia 15% – S. Am. 15%  Coffee Berry Borer – History  Originate in Africa  Now throughout world – Damage  Larvae feed on bean – Control  Berry removal  Chemicals  IPM  Monkeys, birds
Coffee Processing Bean Processing done on the Farm
Wet Method  Start on Harvest Day – Separate trash and defective berries by flotation – Good berries are depulped same day  Fermentation – Only to remove mucilaginous covering – Excessive heat destroys flavor
Wet Method  Washed – Water under pressure  Dried - spread out to dry – Sun – Artificial heat  Best quality – Gives coffee that is cleaner, brighter, fruitier, better acidity
Dry Method (Natural Method) (Most traditional and least expensive)  Drying (Indonesia, Ethiopia, Brazil, Yemen) – Initial drying done on trees – Spread on concrete, tile or matted surfac  2” thick and constantly raked  3-15 days until specific moisture  Pergamino is dry and crumbly
Dry Method (Most traditional and least expensive)  Remove pericarp – Mortar and pestle or machine  Chaff removed via winnowing and picking  Sorted by size, shape, density and color  Packed in 60 kg bags for processing
Industrial Processing (Usually by importing company)  Grading process – Redry and clean the parchment beans before using – Remove testa (hulling and polishing) – Sort on size and density  Roasting (370°F to 540°F) – Removes moisture  Light roast lose 3-5% moisture  Dark roast lose 8-14% moisture – Time (up to 30 min) determines flavor
Industrial Processing (Usually by importing company)  Caffeine Reduction – Add water to beans – Extract with  Methylene chloride and ethyl acetate  Residual solvent removed via low level steam drying – Caffeine can be recovered with water extraction of organic solvent

  • 25. Coffee Tree Growth Cycle  Dry and/or cool season – Floral initiation – Reduced vegetative growth  Wet season – Flowers open, fruit set and begin development – Active vegetative growth  Dry and/or cool season – Fruit ripen – Flower buds initiate – Reduced vegetative growth
  • 26. Coffee Tree Growth Habit  Orthotropic stem – Erect growth  Plagiotropic stems – Horizontal secondary stems growing off of orthotropic stems – These are the fruiting wood
  • 27. Growing Conditions  Grown under many conditions – Plantations – small farms – Under shade – In full sun – Monoculture – Mixed farming systems
  • 28. Coffee Production  Planting – Slightly acid (pH 5.2 to 6.3) well drained soil – Beginning of wet season – Vertical position or 30° angle  Spacing - need light for fruit ripening – Arabica, 1350 trees/ha – Robusta, 900-1000 trees/ha  Time to fruiting – Take 3-4 years to obtain mature plant – Fruit on year old wood
  • 29. Planting and aftercare  Site selection: The selected site should have following provisions;  Water supply : As perennial source  Soil rich in organic matter (humus)  Gentle Slope : Slope towards N or NE or E direction  Drainage : Provision should be there for adequate drainage  Altitude: Minimum of 500 m asl (Arabica 1000 m to 1500m while robusta 500 m to 1000m asl)  Wind break: Eastern wind during December- February causes injury to plants (cold injury). Hence, wind belts of silver oak or orange or tree coffee should be raised  Partial shade: Clear natural vegetation for providing required partial shade to coffee growth. It can be done by selective felling /retention of desired species of wild shade trees in the natural forest vegetation.

  • 35. Coffee Production  Training/Pruning objectives – Maximize # plagiotrophic stems (fruiting wood) – Shape trees  Maximize use of space  Ease of management – Maintain open tree to allow good light penetration – Minimize biennial bearing – Remove diseased and dead wood
  • 36. Types of training  Single stem training: Suitable under India conditions.  Multiple stem: Practiced in American and Latin American countries.  1) Single stem system:  Topping of growing main-stem  Purpose of topping/capping:  1) To restrict vertical growth and facilitating lateral branching giving increased fruiting area.  2) Thickening of main stem: It also helps in diversion of food material to thicken the main stem and primary branches.  As soon as the plant reaches a desirable height (first topping height) the growth of bush is restricted by topping/capping.
  • 37. Raising of second tier:  Depending on the fertility of the soil and spreading of the plant when plants attain about 4.50 to 5 ft height (135 to 150 cm) the second tier is raised.
  • 38. Table: First topping height in coffee Sl. No. Variety Topping height I - Tire (cm) Remarks II Tier height 1 Arabica Tall 60 to 75 ( 2.5 feet) In about 9-12 months stage after planting 4.50 to 5 ft 2 Arabica Dwarfs 90 to 135 ( 3 to 4.5 ft.) 3 Robusta 105 to 120 cm (3.50 to 4 ft) In about 18-24 months stage 4.50 to 5.00 ft
  • 39. Single Stem Training (Central leader)  Cut back orthotropic stem – Encourages plagiotropic stem formation – Select one orthotropic as new leader  Repeat for 3-5 years – With each cycle the tree gets bigger – Lower limbs die due to lack of light  Rejuvenate after 3-5 years – To reduce size of tree – Cut back to 40-50 cm height
  • 41. 2) Multiple stem system (Agobiada system)  Countries: Practiced in African and Latin American countries. Here multiple stems are encouraged by bending the main stem ( i.e., Agobiada system  In India multiple stem training system is practiced under certain circumstances viz., Replanted fields: When old blocks are to be replanted with a new material, the old plants are stumped and converted into multiple stem to yield crops until the new plants come to bearing. High density planting: Here coffee is planted very closely in the initial years and later thinned out to normal spacing.  Here the plants which are to be thinned out ( removed or going plants) are raised on multiple stems for enabling the main plants to spread out their laterals.
  • 42. Multiple Stem Training (Modified Central Leader)  Leave 2-8 orthotropic stems  Pruning – Cut out wood in center – Continues growing taller – Cropping area moves higher  Rejuvenation every 4-6 years – Need to lower fruiting surface – Allow basal suckers to grow
  • 46. PRUNING IN COFFEE Benefits of pruning in coffee:  Yield regulation : Pruning reduces the risk of overbearing in any of the particular year.  Pest and disease incidence : By pruning there will be better entry of sunlight and air in to the bushes there by minimizing the incidence of pests and diseases.  Manageable shape : By proper pruning the tree is maintained in a manageable shape thereby improving the efficiency of field operations viz., spraying, swabbing, harvesting etc
  • 47. Methods Of Pruning 1) Light pruning:  Time of pruning: Starts after the harvest of coffee ( December to February) and continues till the onset of monsoon. However, it is better to prune after few summer showers. Parts pruned during light pruning in coffee:  1) Old branches  2) Unproductive branches  3) Criss-cross branches  4) Dead and broaken/damaged branches  7) Disease and pest affected parts  8) Suckers II) Medium to severe pruning:  Periodicity of medium to severe pruning: It is done once in four years usually to replace the laterals.
  • 49. Manuring in coffee Nutrition Management  Maintaining optimum pH by liming is essential requirement for nutrition management in coffee. If proper pH is not maintained, the applied fertilizers will not be utilised by the plants effectively.  Soil testing at least once in 2-3 years should be mandatory for lime and fertilizer applications.  Use agricultural lime analysing 80% calcium carbonate. November is the best period for lime application. Application of dolomite lime once in a while in rotation is beneficial.  Application of bulky organic manures like FYM or compost @ 5 tonnes/ha once in two years would improve the soil condition and better utilization of applied fertilizers.  The recommended dose of fertilizers should be applied in three splits (post-blossom, pre-monsoon, post-monsoon) by adopting drip circle method.
  • 51. Shade management  Beneficial effects of shade in coffee – Quality improvement: Shade trees form natural canopy and it improves aromatic properties. – Improved foliar health: Shade helps in getting glassy elegant leaves and controls pre mature yellowing of leaves, defoliation and dieback. – Mulching effect: Leaves shed from the shade trees acts as soil mulch which in turn held in conserving the soil moisture and prevents soil erosion and improves soil organic matter status. – Temperature regulation: Insulation effect leading to buffering effect in soil temperature. – Improved organic matter status of soil : Decomposed leafy materials improves organic matter content of soil. There will be minimum loss of humus under shade thereby improving soil physical conditions. – Disease incidence : some of the diseases viz., Cercospora leaf spot and Colletotrichum etc are minimized under shaded situations – Yield regulations: Shaded situations prevents over bearing in any of the particular year and results in less variations / fluctuations in annual yields.

  • 55. Harvesting and yield Hastening fruit ripening in coffee: Purpose: Speedy and uniform ripening will give scope for quick and early harvest = reduced cost of harvesting in coffee. Harvesting the berries: In India there is only one cropping season. Arabica coffee harvested from November to January and Robusta coffee from December to February. The crop will be ready for the first harvest in about 3 - 4 years but economic yields are obtained from 5 - 12 years onwards upto 50 years. The berries are harvested when they turn red to deep crimson colour. Season of harvest is from October to February. Harvesting is done in stages as follows;
  • 56. Harvest  Most done by hand – Ripe berries only  Pick every 8-10 days – In Brazil, allow cherries to dry on tree  Machine harvest in Brazil
  • 57.  Fly picking: Small scale picking of ripe berries from October - November to February.  Main picking: Well formed ripe berries are harvested in December.  Stripping: All left over berries irrespective of ripening are harvested after main picking.  Gleanings: Collection of fruits that have dropped down during harvesting.
