Spur
1. In TN & other states of South India Pandal system is practiced 2. In MH, KA, Punjab and Haryana –Head System, Single stake system and Telephone system is practiced Training Systems
Head System
Advantages • Simplicity in shape • Ease in training • In expensive to establish • Possibility of cross cultivation Dis-advantages • The vines are slow to come to full production • Increased possibility of bunch rot and poor colour • The bud and flower drop is maximum compared to other systems.
Pandal System (Arbour, Pergola, Mandwa, Over head or Bower system)
• High productive potential, bower was a very popular system of training in the past. • It is highly suited for vigorous varieties like Anab-e-Shahi, Bangalore Blue and Gulabi. • Varieties like Thompson Seedless and Tas-A-Ganesh where vine vigour and excessive foliage density affects the productivity adversely, this system is not popular.
Advantages • Greater spread of the vines. • Better exposure of the foliage to the sun, resulting in better maturity of the canes. • Higher production. • More uniform bunch colour • Superior quality of fruits, which are free from sunscald. • The vines in general give uniform performance • It gives good protection to the canes against hot desiccating winds with ease in bird scaring. Dis advantages • It is the most expensive than all other systems • Pruning, training and spraying operations become difficult • The spraying material cannot reach effectively the leaves and shoots.
Telephone system (Overhead trellis / Telephone trellis system)
Advantages • Greater spread of the vine • Better exposure of the foliage to the sun resulting in the better maturity of canes. • Higher production • More uniform bunch colour • Superior quality of fruits free from sunscald • Vines in general give more uniform performance. Dis advantages • Cost of establishment is high. At present rates it may cost 60-70 thousand rupees. • It is a system difficult to develop i.e. vine training needs a lot of skill and effort. • Not suitable for vines making low to moderate growth.
Kniffin System (Espalier system)
Advantages • This system is cheaper when compared with bower system. • The average yields are 10-15 kg per vine when planted at 3.0 mx3.0 m spacing.
Dis-advantages • Cultivation is possible in one way • The lower arms become unproductive after some years. • Its cost of establishment is about 50-60 thousand rupees per hectare. • This system is mainly confined to research institutes and it is not popular with the farmers in any of the regions of the country.
Pruning of grapes • The vines are pruned at the end of 11 to 12 months from planting for the pandal trained vines. • At the end of 18 months, the vine is ready for pruning for fruit. • The pruning consists of mainly thinning out and heading back. • Generally, in medium to vigorous cultivar, 50 % canes are to be headed back to 9 bud level; the fruiting spurs are moved quite away from the centre of the vine.
A. Summer pruning • It is done during March – April in the states of Andhra Pradesh and Karnataka, but in June in Tamil Nadu. • In this pruning, the canes are cut back to one or two bud level for building up the fresh vegetative growth and to build framework. • Hence, it is called ‘back pruning’ or ‘growth pruning’. • The dried canes are also removed.
B. Winter pruning • Vines which have attained the age of one year can be subjected to this Pruning during December in Tamil Nadu. • The mature (about 6 months old) current season canes are pruned. • The entire foliage and immature shoots are removed. • Levels of pruning differ with varieties and can be ascertained by bud forecasting. • In general, Anab-e-Shahi and Bhokri are pruned to 5 bud level, Thompson Seedless 10 buds, • Bangalore Blue 4 buds and Gulabi 9 buds. • An ideal cane for pruning is of pencil thickness. More number of buds is retained on thicker canes and less on thinner ones. This is done to get fruiting canes. This pruning is also called ‘fruit pruning’ (or) ‘forward pruning’
PRODUCTION TECHNOLOGY OF GRAPES.pptx (jayaprakash)
Number of buds to be retained for different varieties • Bangalore Blue : 3-4 buds • Gulabi : 10-12 buds • Thompson Seedless : 10-14 buds • Beauty Seedless : 4-5 buds • Anab-e-shahi : 4-8 buds • Muscat and Pachadraksha : 5-6 buds
• Dormancy breaking chemical – Dormex • Bud breaking in North India – Hydrogen Cynamide (HCN) – 1.5%. -Induce uniform and early bud sprout. • Swabbing of buds with Hydrogen Cyanamide @1.5 - 4% with in 24-28 hrs for forward pruning. • Bud breaking in South India – Thiourea @ 4 %.
MANURE AND FERTILIZERS • Maximum nutrient requirement was reported during blooming stage. • In T.N the manures and fertilizers are applied twice a year after pruning. • Immediately after pruning, urea and super phosphate can be applied. • M.O.P is applied at flowering and fruits formation stage
MANURING Muscat & Seedless Varieties Arab-e-shahi & Other Vigorous Varieties Green leaves ( Kg) 50 50 FYM (Kg) 50 100 Ground nut cake 2 4 Urea (Kg) 0.5 1-2 Super Phosphate (Kg) 1.0 2 M.O.P. (Kg) 1.0 2
Method of fertilizer application • Active root zone depth is 45-75 cm and in a radius of 100-200 cm. • Fertilizer should be applied to reach the active root zone.

Foliar application • Application of Mg (0.02%), Fe (0.2%) and Bo (0.4%) result in high yield, better quality and lower number of unripe/shot berries.
IRRIGATION • Watering immediately after pruning and fertilizer application should be done. • Irrigation at an interval of 5-7days during initial berry development stage till they become pea size and at 10 days interval till maturity is better for good yields. • Watering should be withheld from 25-30 days prior to harvesting to ensure quality of produce. • Excess salt content in irrigation water, with EC value of more then one causes injury to vines. • 15-20 irrigations necessary per season.
WEED MANAGEMENT • Weeds are controlled manually, mechanically or by use of chemical weedicides like, • Pre-emergent: Atrazine (2-3 kg a.i. / ha), Simazine (2.0 - 6.0 kg a.i. / ha), Diuron (2-4 kg a.i. / ha). • Post-emergent: Paraquat (7.5 kg / ha), Glyphosate (2.0 kg a.i. / ha), Dalapon (8.75 kg / ha).( NRC Grapes, Pune: Crop Profile )
FLOWERING,POLLINATION AND FRUIT SET • Grape vines flower in about 18-20 months. • Flowering in the matured grape vine consists of the formation of Analgen or Primordia. • At the time of flowering, the cap of the flower falls from the flower. This is known as Blooming or calyptra fall stage. • In south India, bud burst for vegetative growth takes place in April-May and that for fruiting during October- November. • Fruit bud is initiated in 20-30 days after bud burst depending on varietal character and climatic conditions.
Calyptra

• A few varieties show parthenocarpic fruit formation Stimulative Parthenocarpy • where pollination acts as stimulus and seedless berries develop without fertilization is seen in varieties like Black Corinth. Stenospermocarpy • In a few seedless varieties like Thompson Seedless, Beauty Seedless, Pusa Seedless, Perlette and Delight, Stenospermocarpy takes place in which fertilization occurs followed by embryo abortion after some time.
PRODUCTION TECHNOLOGY OF GRAPES.pptx (jayaprakash)
Heat Requirement • Heat requirement for berry ripening varies from 1600 degree days in early maturity varieties to 3500 degree days in late season ones. • Estimated heat requirement in degree days for some varieties are as follows, under coimbatore conditions. Anab-e-Shahi : 3526 Bangalore Blue : 3562 Bhokri : 3284 Glulabi : 3508
Techniques of improving fruit quality Pruning: • Balanced pruning is essential. Thinning: Excessive bearing of vines can be reduced by cluster thinning or Berry thinning. Ringing or Girdling : • Removing complete ring of bark from any part of vine such as shoot, cane or arm or trunks. • Ringing interrupts the downward passage of carbohydrates through the phloem. • Berry size and crispiness are increased. • The width and depth of girdling are 1-1.5 mm. • Girdling is done at 4-5 mm diameter of the berries. • Girdling will ensure a TSS content of 20°B.
Girdling • Ring of bark removed from any part. One week before bloom - To improve berry set. Just after berry set - To increase berry size. At the beginning of color change • To advance ripening • To obtain uniform colour • Better eating quality
PRODUCTION TECHNOLOGY OF GRAPES.pptx (jayaprakash)
Use of Growth regulators in Grapes Application of gibberellic acid (GA) at 50 ppm, - at the just opened flowers in the clusters (calyptra stage) increases their size. Ethrel is used to advance ripening by a week and improve quality including colour improvement and uniform ripening. It is normally applied at 250 to 500 ppm concentration at berry start ripening stage.
HARVESTING AND YIELD • Grapes is a Non-climacteric fruit. • Grapes berries begin to ripening stage is called veraison. • Period of harvest and yield of different varieties is given below Variety Yield (t/ha) Period of Harvest Average Potential Anab-e-Shahi 45 90 February-May, July, November- December Bangalore Blue 40 60 January-March, June-December Bhokri 30 50 November-December, June-July Gulabi 30 50 January-March, June-December Perlette 40 50 June Thompson Seedless and other seedless varieties 25 50 January-April

Post-harvest technology Packing  The CFB boxes of 2 to 4 kg are very popular for packing grapes.  "Grape Guard" is a brown-coloured paper (which is impregnated with potassium sulphite) which releases sulphur dioxide gas.  Control - grey mould disease of grapes. Prevent of germination and of fungal pathogens like Botrytis, Storage • The grape berries can be kept without spoilage for 7 days at room temperature. • Grapes can economically be stored up to 40-45 days in cold storage. • The optimum storage temperature recommended is 2 - 1.50C. • Fresh grapes can be stored for 90 to 180 days of time at 0-10C and 95%. • Raisins can be stored for long periods of time at room temperature due to low moisture content.

Physiological disorders Blossom-end rot A black sunken spot develops at the blossom-end of the berry which later on spreads with water-soaked region around it. Defective calcium nutrition and assimilation appear to be the cause for it. Spray of 1.0 per cent calcium nitrate may correct it. Boron deficiency The presence of small sized fruits and large sized fruits in the same bunch is known as HEN AND CHICKEN DISORDER. The fruits are sour in taste. Spraying of 0.2% boric acid a week before bloom and another at full bloom control the disorder effectively. Iron deficiency The leaves turn yellow (chlorosis) during iron deficiency and the entire shoot become yellow to yellowish green under extreme conditions. Iron deficiency may occur due to the presence of excess calcium in the soil (lime induced chlorosis). The corrective measure is two sprays of 0.2% ferrous sulphate, one before bloom and the second after fruit set.

Training • Numerous systems for training grape vine – head, kniffin, trellis and bower system of training. • Choice of training systems depends on many factors such as apical dominanace, vine-vigour, cultivars, bearing zone and climate. • In Tamil Nadu, the grapevine is trained over Pandal of 2 m height. • In some areas, like stakes of commiphera (Killuvai) are used for erecting the bowers, in the middle of which the vine is set out. • Recently stone and cement concrete pillars or even G.I. tubes are being used by the growers.
  • 24. The technical terms used in viticulture are as follows: • Trunk - is the main stem of the plant. • Arm - is the branching vine from the trunk. • Shoot - is the young growth of current season. • Cane - is the matured shoot of past season. • Spur - is that portion of cane left behind on the vine when it is pruned. • Fruiting spur - spur with 3 or more buds meant for bearing fruits. • Foundation spur (or) renewal spur - spur with only one bud for giving shoot for next crop.
  • 26. Arm
  • 27. Shoot
  • 29. Spur
  • 30. 1. In TN & other states of South India Pandal system is practiced 2. In MH, KA, Punjab and Haryana –Head System, Single stake system and Telephone system is practiced Training Systems
  • 32. Advantages • Simplicity in shape • Ease in training • In expensive to establish • Possibility of cross cultivation Dis-advantages • The vines are slow to come to full production • Increased possibility of bunch rot and poor colour • The bud and flower drop is maximum compared to other systems.
  • 33. Pandal System (Arbour, Pergola, Mandwa, Over head or Bower system)
  • 34. • High productive potential, bower was a very popular system of training in the past. • It is highly suited for vigorous varieties like Anab-e-Shahi, Bangalore Blue and Gulabi. • Varieties like Thompson Seedless and Tas-A-Ganesh where vine vigour and excessive foliage density affects the productivity adversely, this system is not popular.
  • 35. Advantages • Greater spread of the vines. • Better exposure of the foliage to the sun, resulting in better maturity of the canes. • Higher production. • More uniform bunch colour • Superior quality of fruits, which are free from sunscald. • The vines in general give uniform performance • It gives good protection to the canes against hot desiccating winds with ease in bird scaring. Dis advantages • It is the most expensive than all other systems • Pruning, training and spraying operations become difficult • The spraying material cannot reach effectively the leaves and shoots.
  • 36. Telephone system (Overhead trellis / Telephone trellis system)
  • 37. Advantages • Greater spread of the vine • Better exposure of the foliage to the sun resulting in the better maturity of canes. • Higher production • More uniform bunch colour • Superior quality of fruits free from sunscald • Vines in general give more uniform performance. Dis advantages • Cost of establishment is high. At present rates it may cost 60-70 thousand rupees. • It is a system difficult to develop i.e. vine training needs a lot of skill and effort. • Not suitable for vines making low to moderate growth.
  • 39. Advantages • This system is cheaper when compared with bower system. • The average yields are 10-15 kg per vine when planted at 3.0 mx3.0 m spacing.
  • 40. Dis-advantages • Cultivation is possible in one way • The lower arms become unproductive after some years. • Its cost of establishment is about 50-60 thousand rupees per hectare. • This system is mainly confined to research institutes and it is not popular with the farmers in any of the regions of the country.
  • 41. Pruning of grapes • The vines are pruned at the end of 11 to 12 months from planting for the pandal trained vines. • At the end of 18 months, the vine is ready for pruning for fruit. • The pruning consists of mainly thinning out and heading back. • Generally, in medium to vigorous cultivar, 50 % canes are to be headed back to 9 bud level; the fruiting spurs are moved quite away from the centre of the vine.
  • 42. A. Summer pruning • It is done during March – April in the states of Andhra Pradesh and Karnataka, but in June in Tamil Nadu. • In this pruning, the canes are cut back to one or two bud level for building up the fresh vegetative growth and to build framework. • Hence, it is called ‘back pruning’ or ‘growth pruning’. • The dried canes are also removed.
  • 43. B. Winter pruning • Vines which have attained the age of one year can be subjected to this Pruning during December in Tamil Nadu. • The mature (about 6 months old) current season canes are pruned. • The entire foliage and immature shoots are removed. • Levels of pruning differ with varieties and can be ascertained by bud forecasting. • In general, Anab-e-Shahi and Bhokri are pruned to 5 bud level, Thompson Seedless 10 buds, • Bangalore Blue 4 buds and Gulabi 9 buds. • An ideal cane for pruning is of pencil thickness. More number of buds is retained on thicker canes and less on thinner ones. This is done to get fruiting canes. This pruning is also called ‘fruit pruning’ (or) ‘forward pruning’
  • 45. Number of buds to be retained for different varieties • Bangalore Blue : 3-4 buds • Gulabi : 10-12 buds • Thompson Seedless : 10-14 buds • Beauty Seedless : 4-5 buds • Anab-e-shahi : 4-8 buds • Muscat and Pachadraksha : 5-6 buds
  • 46. • Dormancy breaking chemical – Dormex • Bud breaking in North India – Hydrogen Cynamide (HCN) – 1.5%. -Induce uniform and early bud sprout. • Swabbing of buds with Hydrogen Cyanamide @1.5 - 4% with in 24-28 hrs for forward pruning. • Bud breaking in South India – Thiourea @ 4 %.
  • 47. MANURE AND FERTILIZERS • Maximum nutrient requirement was reported during blooming stage. • In T.N the manures and fertilizers are applied twice a year after pruning. • Immediately after pruning, urea and super phosphate can be applied. • M.O.P is applied at flowering and fruits formation stage

  • 51. Foliar application • Application of Mg (0.02%), Fe (0.2%) and Bo (0.4%) result in high yield, better quality and lower number of unripe/shot berries.
  • 52. IRRIGATION • Watering immediately after pruning and fertilizer application should be done. • Irrigation at an interval of 5-7days during initial berry development stage till they become pea size and at 10 days interval till maturity is better for good yields. • Watering should be withheld from 25-30 days prior to harvesting to ensure quality of produce. • Excess salt content in irrigation water, with EC value of more then one causes injury to vines. • 15-20 irrigations necessary per season.
  • 53. WEED MANAGEMENT • Weeds are controlled manually, mechanically or by use of chemical weedicides like, • Pre-emergent: Atrazine (2-3 kg a.i. / ha), Simazine (2.0 - 6.0 kg a.i. / ha), Diuron (2-4 kg a.i. / ha). • Post-emergent: Paraquat (7.5 kg / ha), Glyphosate (2.0 kg a.i. / ha), Dalapon (8.75 kg / ha).( NRC Grapes, Pune: Crop Profile )
  • 54. FLOWERING,POLLINATION AND FRUIT SET • Grape vines flower in about 18-20 months. • Flowering in the matured grape vine consists of the formation of Analgen or Primordia. • At the time of flowering, the cap of the flower falls from the flower. This is known as Blooming or calyptra fall stage. • In south India, bud burst for vegetative growth takes place in April-May and that for fruiting during October- November. • Fruit bud is initiated in 20-30 days after bud burst depending on varietal character and climatic conditions.
  • 57. • A few varieties show parthenocarpic fruit formation Stimulative Parthenocarpy • where pollination acts as stimulus and seedless berries develop without fertilization is seen in varieties like Black Corinth. Stenospermocarpy • In a few seedless varieties like Thompson Seedless, Beauty Seedless, Pusa Seedless, Perlette and Delight, Stenospermocarpy takes place in which fertilization occurs followed by embryo abortion after some time.
  • 59. Heat Requirement • Heat requirement for berry ripening varies from 1600 degree days in early maturity varieties to 3500 degree days in late season ones. • Estimated heat requirement in degree days for some varieties are as follows, under coimbatore conditions. Anab-e-Shahi : 3526 Bangalore Blue : 3562 Bhokri : 3284 Glulabi : 3508
  • 60. Techniques of improving fruit quality Pruning: • Balanced pruning is essential. Thinning: Excessive bearing of vines can be reduced by cluster thinning or Berry thinning. Ringing or Girdling : • Removing complete ring of bark from any part of vine such as shoot, cane or arm or trunks. • Ringing interrupts the downward passage of carbohydrates through the phloem. • Berry size and crispiness are increased. • The width and depth of girdling are 1-1.5 mm. • Girdling is done at 4-5 mm diameter of the berries. • Girdling will ensure a TSS content of 20°B.
  • 61. Girdling • Ring of bark removed from any part. One week before bloom - To improve berry set. Just after berry set - To increase berry size. At the beginning of color change • To advance ripening • To obtain uniform colour • Better eating quality
  • 63. Use of Growth regulators in Grapes Application of gibberellic acid (GA) at 50 ppm, - at the just opened flowers in the clusters (calyptra stage) increases their size. Ethrel is used to advance ripening by a week and improve quality including colour improvement and uniform ripening. It is normally applied at 250 to 500 ppm concentration at berry start ripening stage.
  • 64. HARVESTING AND YIELD • Grapes is a Non-climacteric fruit. • Grapes berries begin to ripening stage is called veraison. • Period of harvest and yield of different varieties is given below Variety Yield (t/ha) Period of Harvest Average Potential Anab-e-Shahi 45 90 February-May, July, November- December Bangalore Blue 40 60 January-March, June-December Bhokri 30 50 November-December, June-July Gulabi 30 50 January-March, June-December Perlette 40 50 June Thompson Seedless and other seedless varieties 25 50 January-April
  • 66. Post-harvest technology Packing  The CFB boxes of 2 to 4 kg are very popular for packing grapes.  "Grape Guard" is a brown-coloured paper (which is impregnated with potassium sulphite) which releases sulphur dioxide gas.  Control - grey mould disease of grapes. Prevent of germination and of fungal pathogens like Botrytis, Storage • The grape berries can be kept without spoilage for 7 days at room temperature. • Grapes can economically be stored up to 40-45 days in cold storage. • The optimum storage temperature recommended is 2 - 1.50C. • Fresh grapes can be stored for 90 to 180 days of time at 0-10C and 95%. • Raisins can be stored for long periods of time at room temperature due to low moisture content.
  • 69. Physiological disorders Blossom-end rot A black sunken spot develops at the blossom-end of the berry which later on spreads with water-soaked region around it. Defective calcium nutrition and assimilation appear to be the cause for it. Spray of 1.0 per cent calcium nitrate may correct it. Boron deficiency The presence of small sized fruits and large sized fruits in the same bunch is known as HEN AND CHICKEN DISORDER. The fruits are sour in taste. Spraying of 0.2% boric acid a week before bloom and another at full bloom control the disorder effectively. Iron deficiency The leaves turn yellow (chlorosis) during iron deficiency and the entire shoot become yellow to yellowish green under extreme conditions. Iron deficiency may occur due to the presence of excess calcium in the soil (lime induced chlorosis). The corrective measure is two sprays of 0.2% ferrous sulphate, one before bloom and the second after fruit set.
