Plum Fruit Orchard Management

What is Plum Fruit Farming and its Overview?

Plum fruit farming is the cultivation of plums, which are fruits belonging to the Prunus subg. Prunus species. Prunes, often called dried plums, are a common form of plums in the United States. Plums are believed to have been among the first fruits domesticated by humans, originating in the East European and Caucasian mountains and China. They were later introduced to Britain from Asia and cultivated in Andalusia, southern Spain.

Plum trees, when pruned, can reach a height of 5-6 meters and produce drupe fruits with firm and juicy flesh. China is the largest producer of plums, followed by Romania and Serbia. Japanese or Chinese plums are popular for fresh consumption, while European plums are also prevalent in certain regions. Plums can be enjoyed fresh, used for making jams, or even fermented into wine or brandy.

It’s worth noting that plum kernels contain cyanogenic glycosides, but commercial availability of the oil derived from them is limited. Regarding nutrition, raw plums comprise 88% water, 12% carbohydrates, 1% protein, and less than 1% fat. They provide vitamin C but do not contain significant levels of other micronutrients.

Plums, a diverse group of fruit species, are commercially grown as medium-sized trees, usually pruned to 5-6 meters (16-20 ft). With moderate hardiness, they can reach heights of 12 meters (39 ft) if not pruned, spreading to 10 meters (33 ft). Blossoming time varies by region, occurring around January in Taiwan and early April in the United Kingdom. Plums are typically 2-7 centimeters (0.79-2.76 in) in diameter, with a firm, juicy flesh, and smooth peel that adheres to the fruit. They are drupes, with the fleshy part surrounding a single hard fruit stone enclosing the seed.

Importance of Month-Wise Planning for Plum Fruit Orchard Maintenance

Month-wise planning plays a crucial role in maintaining a plum fruit orchard. Each month brings different requirements and tasks that must be addressed for optimal orchard health and productivity. For instance, pruning is typically done during the dormant winter months to shape the trees and encourage fruiting.

Spring is crucial for pollination and pest control, while summer requires careful irrigation and disease management. Harvesting occurs in late summer or early fall, followed by post-harvest activities such as orchard cleanup and tree preparation for the next growing season.

Best Tips for Growing Plum Fruit Orchards for High Profits and Yield

Growing plum fruit orchards for high profits and yield requires following certain tips and techniques. Plum, also known as “Aloo Bukhara,” is a sweet and tasty fruit found in hilly regions and the northern plains of India. It belongs to the Rosaceae family and Prunus domestica genus. Plums come in various sizes and shades of purple, with a fleshy interior and a seed. They are rich in antioxidants and vitamins and can be consumed fresh, dried, or jams.

There are two types of plums: European and Japanese, with over 200 varieties worldwide. In India, plum varieties developed are of Japanese origin and belong to the Prunus salicina group. These varieties require fewer chilling hours, have excellent taste, and can be consumed fresh. Some Indian plum varieties include Kala Amritsari, Satluj Purple, Titron, and Kataru Chak.

Plums thrive in a temperate climate, ranging from the freezing winters of Kashmir to the scorching summers of Rajasthan. They require fewer chilling hours below 7.2 degrees Celsius. The ideal soil for plum cultivation is deep, loamy, sandy soil with a neutral pH range of 5 to 6.5. Proper drainage is essential for productive plum orchards. Propagation of plum trees can be done through cuttings or seeds.

Hardwood cuttings are used for varieties like Kala Amritsari, while the Kabul Green variety can also be used for propagation. The success rate can be increased by using an IBA solution. Kala Amritsari seeds are collected during summer and sown in sandy soil. The seedlings are then transplanted in rows with proper spacing. Planting plum trees is typically done in December, with a distance of 6 meters between plants and rows.

Training and pruning techniques vary based on the variety, with open center systems and modified leader structures commonly used. Proper fertilization is crucial, with the application varying based on the age of the plant. Intercropping with crops like black or green gram, cluster beans, or peas can be beneficial. Fruit thinning should be done to ensure proper spacing between fruits. 

Weed control using glyphosate is important, and water irrigation should be maintained from March to May for better fruit development. Harvesting should be done based on the desired ripeness. Locally sold plums can be picked when fully ripe, while those for transportation should be harvested when half skin color develops. Proper handling and packaging techniques should be employed to avoid damage during transportation.

Plum Fruit Orchard Management

Pruning is an essential aspect of plum fruit orchard management. Annual pruning helps renew the fruit wood, remove vigorous shoots known as “water sprouts,” and ensure adequate light penetration in the lower canopy. The most common training system for plums is the open center or vase-shaped system. Irrigation is crucial for plum orchards, although plums are less susceptible to fruit disorders caused by water stress compared to other stone fruit species like peach and nectarine.

Plum Fruit

Drip or micro-sprinkler irrigation is typically used for plums, with some instances of flood irrigation in Central California. Cross-pollination is necessary for most Japanese plum cultivars as they are “self-incompatible,” meaning they require pollen from another compatible cultivar to set fruit. While some cultivars can achieve limited fruit sets without a pollinizer, commercial production requires adequate cross-pollination. Fruit set without pollinizers can vary across different geographic regions.

When planning an orchard, growers must consider local climate, soil conditions, pests, fruit characteristics, harvest timing, and pollination compatibility. California’s commercial nurseries provide recommendations for compatible cultivars.  Pollinizer cultivars are usually interspersed with the primary cultivar in an orchard. The ratio of pollinizers to primary trees depends on the fruit quality and pollination requirements. Different planting strategies can be employed, such as alternating four-row blocks of pollinizer and primary cultivars or grafting pollinizer limbs onto the primary cultivar.

General Maintenance Operations and Management Practices in Plum Fruit Orchards

Rootstocks
  • Sow peach or plum seeds in late October or early November. The seeds will sprout between February and March.
  • Allow the seedlings to grow until they reach around 7 inches in length and 2mm in diameter.
  • The shield budding technique is best suited for budding, which should be done from May to June.
Seed Collection and Sowing
  • Collect seeds during summer and store them. Sow the accumulated seeds in sandy soil around November, with a 5cm thickness of sand covering the seeds for proper germination.
  • Once shoots appear, transplant the seedlings in rows, maintaining a distance of 8-10cm between each plant and 25-30cm between the rows.
  • Light irrigation is sufficient, and the plants will be ready for grafting the following year.
Planting
  • After growing for approximately one year, the young shoots can be planted in the fields, preferably in December. Maintain a distance of 6 meters between the plants and rows.
  • Adopt a square cultivation system, planting around 270-320 trees per hectare.
Training/Pruning
  • Training depends on the variety, with open center systems suitable for spreading habit varieties (e.g., most Japanese varieties) and modified leader structures for upright growing plants.
  • Alter the leader branches after four years of plantation and collect 4 to 5 secondary branches.
  • Light pruning in January promotes proper growth, and good quality spurs development.
  • Plum fruits appear after one year on older wood spurs.
Fertilizer Application
  • Apply fertilizer according to the soil type, with loamy soil requiring more and hard soil requiring less. The fertilizer composition depends on the age of the plant.
  • For 1-2-year-olds: 5-10 Kilos of Farmyard manure, 50-100 grams of Urea, 60-120 grams of Superphosphate, and 25-50 grams of potash.
  • For 3-4-year-olds: 15-20 Kilos of Farmyard manure, 150-200 grams of Urea, 180-240 grams of Superphosphate, and 75-100 grams of potash.
  • For 5-6-year-olds: 25-30 Kilos of Farmyard manure, 250-300 grams of Urea, 300-400 grams of Superphosphate, and 125-150 grams of potash.
  • For seven years and older: 40 Kilos of Farmyard manure, 300 grams of Urea, 400 grams of Superphosphate, and 200 grams of potash.
  • These maintenance operations and management practices are essential for ensuring the healthy growth and high-quality yield of plum fruit orchards.
