Indian Gooseberry/Amla Orchard Management

What is Indian Gooseberry/Amla Farming and its Overview?

Amla farming involves cultivating the Phyllanthus emblica tree, known as Indian Gooseberry or Amla, for its nutritious and medicinal fruit. The tree is small to medium-sized, up to 8 meters (26 feet) tall. Its leaves are light green and resemble pinnate leaves. Indian Gooseberry, scientifically known as Phyllanthus emblica or Amla, is a deciduous tree belonging to the Phyllanthaceae family. It is native to tropical and southern Asia.

The tree is small to medium-sized, ranging from 1 to 8 meters (3.3 to 26.3 feet) in height. Its branchlets are covered with fine hair-like structures and can measure 10 to 20 centimeters (3.9 to 7.9 inches) in length. The leaves are simple, subsessile (almost stalkless), and densely arranged along the branchlets. They are light green and resemble pinnate leaves.

The flowers of the Indian Gooseberry are greenish-yellow in color. The nearly spherical fruit appears light greenish-yellow and has a smooth, hard texture. It typically displays six vertical stripes or furrows. The diameter of the fruit can reach up to 26 millimeters. While wild Amla fruits weigh around 5.5 grams, cultivated fruits average between 28.4 grams and 56 grams.

Importance of Month-Wise Planning for Indian Gooseberry/Amla Orchard Maintenance

Each month presents unique tasks and considerations that directly impact the health and productivity of the orchard. From pruning and fertilization to pest control and irrigation, strategic planning ensures the timely execution of these activities. For example, pruning in winter stimulates new growth, while fertilization in spring promotes fruit development.

Adequate planning optimizes resource utilization, minimizes risks, and enhances overall orchard health, leading to higher yields and better quality Amla fruits. It is the key to successful orchard maintenance throughout the year.

Best Tips for Growing Indian Gooseberry/Amla Orchard Maintenance Practices

Indian Gooseberry, also known as Amla or Aonla (Emblica officinalis), is native to the Indian subcontinent. India leads the world in both area and production of this crop. Apart from India, Amla trees are naturally found in different parts of the world, including Sri Lanka, Cuba, Puerto Rico, USA (Hawaii & Florida), Iran, Iraq, Pakistan, China, Malaysia, Bhutan, Thailand, Vietnam, Philippines, Trinidad, Panama, and Japan. The most popular cultivable varieties of Amla are Banarasi, NA 7, Krishna, Kanchan, Chakaiya, and BSR 1.

Soil: Indian Gooseberry or Amla thrives well in light to medium-heavy soils. Purely sandy soil should be avoided. The tree is adaptable to dry regions and can also grow in moderately alkaline soils. Amla is a subtropical plant that thrives in dry climates. It is a hardy plant and can adapt to different soil conditions. The crop has good tolerance to salinity and alkalinity.

Climate: Amla grows in a tropical climate. A rainfall of 630-800 mm per year is ideal for its growth. Young plants under the age of three should be shielded from high winds in May and June, as well as frost in the winter. Mature plants can tolerate freezing temperatures and high temperatures up to 46°C.

Spacing and Planting: For planting Amla, seedlings, grafts, and buddings are used. The ideal time for planting is during July-August, with a recommended spacing of 6 x 6 meters. The pits for planting should be either 1 x 1 meter or 1.25 x 1.25 meters. Before planting, each pit should be filled with surface soil mixed with 15 kg of FYM and 0.5 kg of phosphorus. Additionally, 30 g of nitrogen should be applied each year during September-October for up to 10 years for each tree.

Dig pits of 1 m³ from May to June at a distance of 4.5 x 4.5 m. Expose the pits to sunlight for 15-20 days. Fill each pit with surface soil mixed with 15 kg of FYM and 0.5 kg of phosphorus before planting the grafted seedlings. Plant at least three varieties in a ratio of 2:2:1 to ensure pollination and maximum yield. For example, in an acre, plant 80 grafts of NA-7, 80 grafts of Krishna, and 40 grafts of Kanchan.

Irrigation is required to establish the plants. However, no irrigation is needed during the rainy and winter seasons. Drip irrigation is suitable as it can conserve water up to 40-45%. After the monsoon rains, drip irrigation should provide approximately 25-30 liters of water per day per tree from October to December.

Pruning and Manuring: The main branches should appear 0.75-1 meter above the ground level to promote proper branching. Training the plants to a modified central leader system is recommended. Encouraging two to four branches with wide crotch angles, appearing in opposite directions, in the early years is beneficial. After pruning, manuring should be done immediately. The following manures and fertilizers are recommended for bearing trees: 10 kg of Farm Yard Manure (FYM), 200 g of nitrogen (N), 500 g of phosphorus (P), and 200 g of potassium (K).

Intercropping options include green gram, black gram, cowpea, and horse gram for up to 8 years.

Plant protection: Regarding plant protection, Amla orchards may face pests such as gall caterpillars and bark-eating caterpillars. The gall caterpillars bore into the shoots during the rainy season, causing damage. Infected apices should be cut off, and a prophylactic spray of systemic insecticide like Dimethoate 0.03% can help control the pest. Bark-eating caterpillars damage the stems and branches of mature trees, and affected portions should be cleared with a few drops of kerosene applied in the holes to control them.

Harvesting: Amla trees start bearing fruit after two years of planting. Harvest the fruits during February when they turn dull greenish-yellow from light green. Mature fruits are hard and require vigorous shaking or the use of long bamboo poles with hooks for harvesting. A well-maintained tree can yield 50-70 kg of fruit at around ten years of age. The average weight of the fruit is 65g, and each kilogram contains about 15-20 fruits. A well-maintained tree can continue to yield fruit up to the age of 70 years.

Yield: Amla trees yield about 100 kg of fruit per tree annually. Rust is a common disease that appears as circular reddish spots on leaves and fruits. Spraying 0.2% Mancozeb for 7 to 28 days from July to September can help control rust.
