  1. Introduction • Mango is cross pollinated and heterozygous annual fruit crop if propagated by seed (stones) leads to large scale variation in progenies. • Commercially various vegetative propagation methods are successfully adopted in Mango seedling nursery under protective structures. • The best one is Shade Net House for propagation of Mango seedlings in nursery.

  2. Establishment of Shade Net Nursery • A shade net house of 20m x 10m size and 2m height should be erected using a framework of GI (Galvanized Iron) pipes. • UV (Ultra Violet) stabilized HDPE (High Density Polyethylene) shade net of 50 % intensity is used to cover the nursery. • 40 mesh UV stabilized nylon insect proof net is used to prevent entry from outsider pests in shade net house.

  3. Selection of Seed • Theseed are collected from fully mature or riped Mango fruits. • The seed should be free from post harvest diseases and seed /stone weevils. • Mango seeds/stones lose viability to germinate in a short time and therefore, seeds should be sown within a week after collection. • Husking or decortications of the hard endocarp of seeds improves germination. • Before sowing, stones should be treated with 1 percent organo-mercurial fungicides to check soil borne diseases.

  4. Methods of Vegetative Propagation • Select the proper propagation method which you can adopt in the nursery and followed it. • Raising of Rootstocks. • The seeds are raised in polythene bags with perforations at the base of polythene bags for drainage. • The polythene bags are filled with a mixture of garden soil and compost in equal proportion (1:1). • Germination of seed / stone takes place within 10-15 days after sowing.

  5. Preparation of scion • Scion sticks should be prepared from healthy and disease free mother plants of the desired Mango variety. • Scion sticks are defoliated 8-10 days before separation from mother plant for grafting operation. • The length of scion should be 10 to 20 cm. Very short or very long scion stick should be avoided in Mango grafting.

  6. After Care • The seedlings are regularly irrigated and fertilized to attain satisfactory growth. • Seedlings must be kept free from diseases and pest by timely application of fungicides and insecticides . • The nursery should be closed monitored for weeds and sanitation. • Union of the graft takes place after 8-10 days of grafting operations. • The polythene strip is removed after successful union.
