Climate

• Tropical climate
• Cultivated up to an altitude of 1000 m or so elevation.
• Strong wind and cold are harmful to its cultivation.
• The average annual rainfall should not exceed 75 cm.

Soil

• Well-drained, deep (1.5 m), medium to light soil is suitable.

Propagation

• Mainly done by seed.

Planting

• In the summer season, 60-75 cm³ sized pits are dug.
• Lime is planted at a distance of 5×5 or 6×6 meters.
• The best time for planting is the onset of monsoon.

Manure and Fertilizers

• FYM – 50 kg, N : P: K – 500 gm: 400 gm: 900 gm/tree from the 5th year onwards.
• Every year it is given for the first time in spring before flowering in December-January and the second dose in June-July.

Irrigation

• At an interval of 15-20 days in winter and at an interval of 8-10 days in summer.
• Adequate soil moisture should be maintained during fruit formation and fruit development.

Interculture and Intercropping

• Weeding once or twice a year (after monsoon)
• Legumes or some vegetables can be taken in the early stages of growth.

Training and pruning

• Training is done in the initial stage, and if necessary support is provided with bamboo sticks.
• Later pruning of unwanted branches of the trees can be done.

Flowering and Fruiting

• The tree starts flowering in the fourth year after planting.
• The fruits ripen six months after flowering.
• Spraying of ZnSo₄6% + 2, 4-D 20 ppm in early January results in more fruit setting, minimum fruit drop, and higher fruit yield.

Harvesting

• In Gujarat, 60% of the total crop is harvested from July to September, 30% from October – January, and 10% from February to May.
• In North India Harvesting is done from August – September.
• Fruits are harvested when the rind colour changes from green to yellow.
