Grapes Orchard Management

What is Grapes Farming and its Overview?

Grapes, scientifically known as a berry, belong to the Vitis genus and grow on deciduous woody vines. They are considered a non-climacteric fruit and are commonly found in clusters. Grape cultivation dates back approximately 8,000 years, and grapes have played a significant role in human food consumption. Apart from being enjoyed fresh, grapes are dried to make raisins, currants, and sultanas. Furthermore, grapes hold cultural importance worldwide, particularly in winemaking. Additionally, grapes create various products such as jams, juices, vinegars, and oils.

Grapes exhibit diverse colors, including crimson, black, dark blue, yellow, green, orange, and pink. Surprisingly, “white” grapes are green and have evolved from purple grapes due to mutations in specific regulatory genes that disable anthocyanin production, responsible for purple grape coloration. The presence of anthocyanins and other pigment chemicals, part of the polyphenol family, contribute to the varying shades of purple in red wines. In terms of shape, grapes typically resemble an ellipsoid, similar to a prolate spheroid.

Importance of Month-Wise Planning for Grapes Orchard Maintenance

By implementing a well-structured plan, grape growers can strategically address various tasks and challenges specific to each month. During spring, pruning, training, and trellis maintenance focus on shaping the vines and promoting healthy growth. Summer months require attention to watering, pest control, disease prevention, and monitoring grape development. As autumn approaches, activities shift towards harvesting, proper storage, and post-harvest care. Finally, winter is the time for vineyard renovation, soil management, and preparation for the upcoming season.

Best Tips for Growing Grapes Orchard Maintenance Practices

Economic Importance: Grapes hold significant economic value as a fruit crop with multiple objectives, including table consumption, export, winemaking, and raisin production. Fresh grapes provide essential minerals like calcium, phosphorous, iron, and vitamins such as B. Additionally, renowned champagnes and other dessert wines are derived from grapes.

Climatic Requirements: Grapes thrive in a Mediterranean climate, growing and producing fruit during hot and dry periods. In South Indian conditions, the vine’s vegetative growth occurs from April to September, followed by the fruiting period from October to March. Temperatures between 10°C to 40°C impact yield and quality. High humidity and cloudy weather increase the risk of fungal diseases and affect the sugar-acid ratio.

Soil Preference: Grapes adapt well to various soil conditions, but the highest yield and quality are achieved on fertile soils with a pH range of 6.5 to 8.5, organic carbon content above 1.0%, free from lime, and possessing moderate water-holding capacity. Medium yield with high Total Soluble Solids (T.S.S.) can be obtained on medium-type soils.

Rooted cuttings are occasionally planted in the field, while grafting uses suitable rootstocks and varieties.

Planting and Season: Grape planting typically occurs from October to January, with rare planting instances during June-July when the monsoon is delayed. Monsoon planting is avoided to prevent diseases in young growth. Planting trenches are dug in the N-S direction and filled with organic manures, fertilizers, and amendments based on soil type, variety, and training method. Spacing between rows ranges from 2 to 3 meters, with distances within rows adjusted accordingly.

Intercultural: Several important aspects of grape orchard maintenance include gap filling, recutting for uniform growth, supporting vines with bamboo, regular weeding, irrigation management, application of fertilizers, and plant protection measures based on pest and disease incidence.

Care of Young Orchard: Young grape vines require specific care during the first 1.5 to 2 years after planting. This includes training the vines on suitable trellises, initial pruning for trunk and arm development, application of fertilizers, and adherence to plant protection schedules.

Special Horticultural Practices: Pruning and training play vital roles in grapevine management. Pruning is done twice a year, with the first round in April for new vegetative growth and the second in October for fruiting canes. Girdling techniques can be employed during bloom to enhance fruit set, weight, T.S.S., and maturity. Hormones like GA3 and CCC are used at different stages and concentrations to increase yield and improve bunch quality.

Irrigation: Grape cultivation requires regular irrigation. Flood irrigation intervals range from 5-7 days in summer, 8-10 days in winter, and 15-20 days in the rainy season. Drip irrigation involves applying 40-50 L per day per vine during summer, with reduced amounts during other seasons.

Nutrition: To ensure a good crop yield and quality, grapevines require balanced nutrition using chemical, organic, and biofertilizers. Application rates of nitrogen (N), phosphorus (P), and potassium (K) range from 700 to 900 kg/ha/year, 400 to 600 kg/ha/year, and 750 to 1000 kg/ha/year, respectively. Various fertilizers and techniques, such as fertigation, are employed to optimize grape production.
