Ideal Nutrient Management for Litchi Orchards to Enhanced Yield and Quality

Nursery Production and Nutrient Management in Litchi Orchards

Litchi plants can be successfully propagated through the air layering technique, also known as Gootee. In North India, air layering is typically performed from mid-July to September. To prepare the air layers, select terminal growth from the previous season, which should be about 45-60 cm long and 1.0-1.25 cm thick.

Remove a bark ring with a thickness of 4 cm from the middle of the selected shoots using a sharp knife. This prevents the downward flow of carbohydrates and photosynthates. The wood portion (xylem) should remain undisturbed to ensure an uninterrupted flow of water and mineral nutrients to the upper leaves. Choosing shoots that are not directly exposed to the sun is advisable. Shoots facing the northeastern and northwestern aspects of the tree canopy tend to produce more roots on the girdled portion.

Place sphagnum moss grass around the cut portion to promote root growth, and wrap it with a polythene strip. Tie the ends tightly to prevent drying. After a few weeks, roots will start emerging from the growing points formed by the cambium, which will be visible through the polythene sheet. Once many roots have developed, cut the Gootee from the mother tree just below the rooted portion. Dip the rooted portion in water and keep it in the shade. Prepare nursery beds under partial shade.

Gently remove excessive leaves and polythene covering around the rooted portion. Transplant the Gootee into pre-prepared holes slightly larger than the rooted portion. Fill the space around the Gootee with fine soil and press gently to avoid injury to the roots. Keep these rooted layers in the nursery for at least two years before transplanting them into the field to allow for sufficient root system development.

Harvesting Litchi
Soil Preparation and Nutrition Management

When preparing the soil in the pit for litchi plantation, mixing it with soil collected from the root zone of existing litchi orchards is recommended. This soil contains Mycorrhizae fungus, which aids nutrient uptake and root development. Integrated nutrient management is essential for proper vegetative growth and fruit yield. It is important to find the nutrient status of the soil and plants. During February-March, collect leaf samples from the mid-portion of 4-5 months old leaves of the autumn flush.

These samples should be collected from the second and third pairs of leaflets, starting from the terminal apex downwards. To prevent nutrient deficiency, fertilizer application should be based on soil and leaf analysis. Follow the recommended fertilizer schedule, starting with the plantation of Litchi in the orchard. Apply the entire dose of farmyard manure (FYM), single superphosphate, and muriate of potash in December. Divide the urea dose into two equal splits, applying half in the middle of February and the other half in mid-April after fruit.

Best Optimizing Litchi Orchards Conditions to Enhanced Yield and Quality

Canopy Management
  • Rejuvenating old orchards is done in August-September by pruning the trees.
  • Bordeaux mixture is applied to cut end portions to prevent fungal diseases.
  • New shoots are spaced out, and only 4-5 branches are kept on each pruned limb.
  • The application of recommended doses of fertilizers and light irrigation follows pruning.
  • Commercial bearing starts 3-4 years after pruning.
  • Tall and exhaustive crops should be avoided as intercrops in litchi orchards.
  • Legume field crops are recommended as intercrops to fix atmospheric nitrogen.
  • Filler crops like plum, peach, kinnow, and guava can be planted temporarily, but they should be removed when they start interfering with the main crop.
Fruit Bagging

Litchi fruit bunches can be covered with non-woven polypropylene bags to enhance fruit quality and reduce fruit cracking and pests.

  • Pre-bearing stage orchards are irrigated weekly/fortnightly.
  • Excessive irrigation should be avoided as it can damage the roots and cause decline and drying of trees.
  • Regular irrigation should be initiated in bearing orchards after the fruit set stage.
  • Critical fruit development stages require irrigation twice a week.
Harvesting and Storage
  • Litchi fruits are harvested based on visual appearance and eating quality.
  • Harvested fruits should be stored at low temperatures (2-3°C) with high humidity (90-95%) to enhance shelf life.
  • Fruits can be stored for 1-2 weeks, depending on maturity.
  • Short harvesting window and poor shelf life create market challenges.
  • Self-marketing or forming cooperative groups can help improve income and reduce price disparity.
  • Postharvest facilities like pack houses and storage infrastructure are recommended.
Plant Protection
  • Litchi fruit nut borer is a major insect pest that causes economic losses.
  • Pruning, orchard floor management, and regular plowing are recommended to control pests.
  • Spraying insecticides and fungicides at appropriate stages can help control pests and diseases.

Deficiency Nutrient Management Strategies to Enhance Litchi Production

Nitrogen (N): Nitrogen deficiency causes yellowing of older lower leaves, resulting in a light green appearance in the entire foliage. Severe deficiency leads to pale-yellow chlorosis starting from the leaf tip, which progresses to the whole leaf. N deficiency affects branching, fruit yield, leaflet size, panicle emergence, and root growth. It is common in soils with low organic carbon content, light-textured soils, intensive cropping systems, and waterlogged conditions.

Phosphorus (P): Phosphorus deficiency stunts vegetative growth, reduces leaflet size, and lowers fruit production. Older leaves exhibit a dark to light green coloration that can change to reddish-brown or purple. Leaf necrosis, curling, and premature leaf drop may also occur. P deficiency is common in regions with low soil organic carbon content, soils exhausted by intensive or intercropping, acidic soils, and soils where the topmost layer has been removed.

Potassium (K): K deficiency reduces the internodal length and unhealthy dark green leaf growth. It is a mobile nutrient, translocating from older to younger leaves. Symptoms include pale-yellow chlorosis on leaf tips and necrosis of leaf margins. K deficiency affects fruit set, fruit size, pericarp color, and pulp/stone ratio. It is common in soils with light texture, low organic content, high Na, Mg, and Ca concentrations, high bicarbonate content in irrigation water, and acidic soils with pH < 6.0.

Calcium (Ca): Ca deficiency results in small branches and drastically reduced yield. Deficiency symptoms first appear on younger leaves, which are usually malformed. Necrotic patches develop in the interveinal tissues, progressing toward the leaf margin. Ca deficiency occurs in sodic soils with high exchangeable sodium percentages, low calcium content, and highly leached acidic sandy soils.

Magnesium (Mg): Mg deficiency causes pale green leaves, pale yellow interveinal chlorosis, low branching, necrotic leaf margins, and leaf dropping. Plants affected by Mg deficiency exhibit poor growth and a dull appearance. It is common in soils with high Ca or K content, acidic soils with low cation exchange capacity, and leached soils due to heavy rainfall.

Zinc (Zn): Zn deficiency results in stunted vegetative growth, pale and smaller leaflets, bronzing, smaller fruits with lower pulp/stone ratio, and sugar content. Symptoms include irregular interveinal chlorosis on fully mature newly emerged leaves, where veins remain green. Zn deficiency intensifies with the higher application of nitrogen fertilizers and is common in soils with pH > 7.5, leached sandy soils, and soils with excessive phosphatic fertilizer application.

Iron (Fe): Fe deficiency causes chlorosis of young leaves, spreading to older leaves and dieback of branches under severe conditions. It appears in soils with low organic matter, high pH, calcareous soils with high bicarbonate content, and soils with excessive phosphatic fertilizer application.

Boron (B): B deficiency leads to short leaves, wilting, necrotic symptoms, reduced pollen viability, poor fruit set, and cracking. It occurs in light-textured leached soils, calcareous soils, and soils excessively fertilized with potassic fertilizers.

Copper (Cu): Cu deficiency appears on older leaves, resulting in short leaves with interveinal pale greenish to pale yellow. Branch dieback and downward bending of leaf margins may occur. Cu deficiency is common in alkaline and calcareous soils, leached acidic soils, and soils with higher organic matter content.

Manganese (Mn): Mn deficiency causes pale-yellowish interveinal chlorosis in the middle portion of older leaves, progressing towards the tip and leaf base. The upper leaf surface may develop a purplish luster. Mn deficiency is less common but may occur in light-textured soils.

Nutrient Management Through Fertilizer Applications in Litchi Orchards

  • The timing of fertilizer application depends on the age of the trees. The initial phase of establishing the orchard should focus on creating healthy plantations rather than expecting immediate yields. Generally, newly established plantations only require a small amount of fertilizer. 
  • However, applying sufficient farmyard manure (FYM) benefits low-fertility soils. This provides nutrients to the plants and improves soil conditions and its ability to hold water and nutrients. In the pre-bearing stage, urea is applied in three equal split doses in February-March, June-July, and August-September. 
  • During the bearing stage, urea is applied in two equal splits, with half the dose in mid-February and the other half after the fruit set in April. FYM, single super phosphate (SSP), and muriate of potash (MOP) were applied in December. If any micronutrient deficiency is observed, it can be sprayed as needed.
  • When applying fertilizers, it’s important to consider the shallow root system of litchi trees. Fertilizers should not be applied near the base of the plants to avoid causing damage. Instead, manures and fertilizers should be applied in a circle about one meter inside the plant’s canopy and mixed into the soil. 
  • Light irrigation can be applied if the soil moisture is low during fertilizer application. A pit measuring 1 meter by 1 meter by 1 meter should be dug to facilitate better root penetration. The pit should be exposed to sunlight for at least 15 days to disinfect the soil. 
  • Adding 15 ml of Chlorpyriphos 20 EC mixed with about 2 kg of soil to each pit helps protect against white ants. The soil in the pit for litchi plantation should be mixed with soil collected from the root zone of litchi orchards as it contains Mycorrhizae fungus, which aids in nutrient uptake and root development. 
  • The pits should be filled to a height of about 2-5 cm above the ground level using a mixture of well-rotted farmyard manure, silt, and topsoil in equal proportions. Finally, thorough irrigation should ensure the loose soil settles properly.
