Cultivar: Assam Lemon (Local).

The time of planting is May to August.

Loamy soil with uniform texture upto a depth of 3 m is ideal, for cultivation. Avoid waterlogged conditions.

Before monsoon, pits of 0.5m x 0.5m size with a spacing of 3m x 3m are prepared and refilled with soil-manure mixture (1:1) and then allowed to settle.

Propagation :
1. Stem cutting 2. Leaf bud cutting 3. Air layering
1. Stem cutting : The cuttings are usually prepared from fully matured stem. The size of cutting is 18 to 20 cm in length with a thickness of lead pencil. The upper cut is made 1 cm above the node and lower cut close below the node in a slanting manner. The cuttings are planted with a spacing of 30 cm x 30 cm in a slanting position in the nursery bed measuring 30 cm x 1 m x 10 m. The bed is prepared with a mixture of 1:1:1 decomposed cowdung, soil and sand respectively.
2. Leaf-bud cutting : Leaf-bud cutting should be taken from the branch having healthy well developed bud and actively growing leaves. The cuttings consist of a leaf blade and short piece of the stem measuring 2 cm. The nursery bed should be prepared with a mixture of leaf-mould, soil and sand in a ratio of 3:2:1. The cuttings are planted in rows 15 cm x 25 cm spacing and buried upto 2/3rd to their length in a slanting position. Before planting, cutting should be treated with plant growth regulator, viz. IBA (500 ppm) or Seradex B. The sprouted cuttings can be transplanted within 1 year in the field.
3. Air layering : The first step in air layering is to remove completely a strip of bark 3 cm in width at a point 15cm or more below the tip end. Scraping the exposed surfaces to ensure complete removal of the phloem and cambium is desirable to retard healing. About one to two handful of only slightly moistened sphagnum moss or mud pudding with a mixture of well decomposed cowdung, soil and sand with a ration of 1:1:1, respectively is placed around the stem to cover the cut surface. Then a piece of polyethylene sheet 15 to 20 cm wide is wrapped carefully around the branch so that the sphagnum moss or mud is completely covered. Both the ends of the polyethylene sheet should be tied firmly so that the moss or mud does not dry up.
The best time for Stem cutting, Leaf-bud cuttings and Air layering is MarchApril. Stem cutting may be raised in polyethylene bags under partial shade as the best nursery techniques.

Micronutrient: Spray 0.2 %( 2 ml per litre of water) of Polymax or Multiplex during new flushes.

Orchard Management: Weeding should be done frequently at monthly intervals. Paddy straw or black polyethylene can also be used as mulch for controlling weeds. To produce off-season crops, 15cm pruning after the harvest of main crop with a single spray of cycocel at 3000 ppm is recommended. Three irrigations at 15 days interval @ 15 lit/plant combined with black polythene (50 micron) mulching 1st week of November is effective in producing off-season crop (1st week of March).

Planting: Before monsoon, pits of 0.5m x 0.5m size with a spacing of 3m x 3m are prepared and refilled with soil-manure mixture (1:1) and then allowed to settle. The time of planting is May to August.

In the nursery stage, pruning should begin soon after the seedlings start sprouting from the Stem cutting or Leaf bud cutting or Air layering. After planting in the main field, upto 50-60cm from the ground level all side branches should be removed keeping only single main trunk. Above 50-60cm, pruning is confined to the training to develop. Mechanically strong trees with well spaced scaffold limbs before the onset of fruit setting. At the bearing stage, during winter when bearing of tree is low, the branches touching the ground should be cut close to the laterals without leaving any stub. All diseased, injured, cris-cross branches and water sprout should be removed.

This mixture is to be applied in two split doses, i.e. during February/March and October/November.
Fertilizer should be applied leaving about 15-45cm space around the tree trunk and well beyond the canopy spread. It should be incorporated into the soil by light hoeing.

Harvesting: After 2nd year of planting the plants start bearing. Bearing of Assam Lemon is continuous throughout the year. Harvesting should be done when fruits become fully matured. Peak period of bearing is July to September.
Benefit: Cost ratio: 3.50 after 4 years & 7.80 for full bearing plants
