Ginger is grown in all over the country but wet and intermediate zones are major growing areas. Total cultivated extent in 2007 was 6000 ha and Kurunagala, Kandy, Gampaha, Colombo and Kegalle were main growing areas. In the western province ginger is largely grown as an inter crop with coconut and as a home garden crop.

Rangoon ginger- Rhizomes are medium in size and with well spreaded finger rhizomes.

Soils and Climatic needs

Well drained fertile sandy loam soils are the most suitable soil type.

Altitude – successfully grown in areas up to 1500MSL
Rain fall - Rain fall should be 1500 mm or more. If rain fall is low crop should be grown under irrigation.  
P.H - should be 5.5 – 6.5  
Medium shade is good for the successful growth
Ginger is a seasonal crop and the best time to cultivate ginger is between the middle of March and early April. Generally it takes 8-10 months to get yield. However in dry zone areas ginger is cultivated November-December season.

Crop establishment

Planting material:
Matured lateral rhizomes are the most suitable planting material. Piece of rhizome should be 40-50g in weight and be with 6-8buds. Planting material should be disease free and selected from a high yielding cultivation. Before planting rhizomes should be immersed in a fungicide (captan) for about 5-10minutes to avoid fungal growth during planting..
Planting material requirement is 1500kg/ha.

Field Planting

Ginger is planted in raised beds or on ridges. Field should be ploughed up to 35-40cm in depth and tilling soil is done. Beds are 100cm in width and length is vary width the space available. However when inter cropped with coconut width and length can be changed according to the available space. Height of the bed is about 15cm and drains, with 50cm in depth, should be prepared in between beds.
Spacing – between rows – 30cm
between plants – 25cm
04 rows per bed
Planting depth - 5-7.5cm               
Planting should be done after the rain. If no adequate moisture beds should be irrigated.

Crop management

To protect moisture and to keep weeds under arrest mulching should be done immediately after planting. Straw, coir dust, dry leaves or coconut leaves are most suitable mulching material.

Fertilizer application
To add adequate Ca and Mg dolomite is mixed with the soil immediately after ploughing at the rate of 2 mt./ha. To get a higher yield saw dust ash also added to the soil at the rate of 3-4kg/sq, meter of the bed during land preparation period.

Fertilizer recommendation

  Time Organic fertilizer Urea(kg) TSP (kg) MOP (kg)
Basal At the time of planting 20 mt   100  
1st app. After 01 months - 65   100
2nd app. After 03 months - 65   100

Fertilizer is applied after weeding and should be mixed with the soil. After that beds should be mulched. Fertilizer is applied with rain or should be irrigated after fertilizer application.     
In addition glyricidia leaves can be added as an organic fertilizer and thereby can cut down the need of chemical fertilizer and to protect the soil moisture.

Weeding has to be done after one month of planting. The second weeding is done after three months of planting and the beds should be mulched again to protect the moisture. Cleaning drains and earthling up also done with the weeding.

Crop Protection



Harvesting and Post Harvest practices
