Pakistan produces chilies, coriander, garlic, onion, and turmeric in commercial quantity but its ginger production is not enough to meet local requirements. Its large scale commercial cultivation is limited to just 10 districts in upper, middle, and lower Sindh. Ginger is propagated by its stem rhizome, cut into small pieces with one or two eye-buds on each piece which generates new shoots within 8-10 days after sowing.
It can also be sown in flatbeds and on ridges, and the seed of which should not be planted deep. Ginger grows in semi-tropical and temperate zones. High temperatures are desiccating and result in death of the seedlings. Ginger grows well in sandy clay and clayey loam soils with adequate organic matter for retention of moisture.
The climatic conditions especially in Sukkur, Mirpurkhas, and Dadu are most favorable for ginger cultivation which can be further exploited by providing technology and incentives to the growers.
