The 'Langra' Mango, also known as the Banarasi Langra, is a mango cultivar mostly grown in Varanasi in Northern India. The 'Langra' fruit is also known as 'Malda' Mango in parts of northern India and Bihar, referring to the town of Malda in West Bengal. It is usually harvested in the second half of July Month. It's mostly used for slicing and canning.
They're flavored with exotic scents that can be found in big urban marketplaces, especially Varanasi. Produced by local farmers, they may be exported rather easily to other parts of the state. The skin color of the langra mangoes is yellowish and exceedingly light; it has a unique appearance and personality.
Soil and Climate Requirements
-
Mango thrives in any sort of soil as long as it is deep and well-drained.
-
Soils with a red loamy texture are good for cultivation.
-
Alkaline, poorly drained, and rocky substratum soils are not appropriate for mango crop production.
-
Mango is grown in India on lateritic, alluvial, and other soil types.
-
Rich, medium, and well-drained soils give better outcomes.
-
It can be grown in both tropical and subtropical climates.
-
It can tolerate a wide range of environmental conditions.
Propagation Technique
Mangoes can be grown from seed or vegetatively propagated. Several vegetative propagation strategies have been attempted, with varying degrees of success. Because most commercial cultivars in India are cross-pollinated and nonembryonic, seed propagation is unable to preserve the characteristics of the parent tree, while being simple and inexpensive. Plants also take longer to produce fruit. It is necessary to cultivate seedlings for use as rootstocks.
Spacing
Mango trees are generally planted at a range between 7 to 10 meters. It fluctuates between 5 × 5 m and 6 x 6 m under high-density planting. Amrapali is a North Indian cultivar that is ideal for dense planting.
Fertilizer Application
From the first to the tenth year of age, 170 gm urea, 110 gm single super phosphate, and 115 gm muriate of potash per plant per year, and then 1.7 kg, 1.1 kg, and 1.15 kg of these fertilizers per plant per year, respectively, can be applied in two equal split doses (June-July and October). In sandy areas, a foliar spray of 3% urea is recommended before flowering.
Pest Management
Pest: Fruit Fly
The pest can be controlled by spraying Fenthion 2 ml/lit or Malathion 2 ml/lit. The pupae will be exposed if the interspaces are ploughed. Female insects will be attracted to and killed by a pheromone trap with 1 ml of methyl eugenol in 1 liter of water + 1 ml of malathion solution.
Disease Management for Mango Malformations
-
Planting materials that are disease-free are used.
-
Plants that are infected should be removed.
-
Spraying 100-200ppm NAA during October reduced the incidence.
-
Pruning of unhealthy parts with the apparently healthy basal 15-20 cm portions.
-
After that, Carbendazim is sprayed (0.1 percent).
Harvesting and Yield
From fruit set to maturity, mangoes usually take 90-120 days. Pole harvesters are used to pick the fruit without causing any damage to it.
Mango grafts bear fruit in around 2-3 years, but commercial yields can be obtained in as little as 8-10 years and can last up to 40-60 years. The average yield of Langra Mango is 8 tons per hectare.
