properties of soil 6. Protects the setts and sprouts from hot sun 7. Provides favourable conditions for the sprouting of the setts. First mulching is to be done at planting with 10-12 tonnes of green leave per ha. Second mulching is done at 40-60 days after first mulching with 5 tonnes of green leaves. Farm yard manure is spread over the green leaves. In irrigated crop – raise cow pea and black gram as live mulches. Remove the mulches 60 days after sowing during rains. Castor seeds are sown on bunds at 9 m intervals, to serve as wind breaks. Irrigation: Irrigate at 4- 10 day interval. During mid September to 3rd week of December irrigate at fortnightly interval. Manuring: At the time or before planting 25 – 30 tonnes of cattle manure 50 kg P 2 O 5 ; 25 kg K 2 O are applied as basal dressing. At 60 and 90 days after planting Nitrogen is applied in two splits @ 37.5 and 37.5 kg per ha along with 25 kg K 2 O. In Andhra Pradesh: Basal dose: 15-20 tonnes of FYM per ha : 60 kg P 2 O 5 ; 30 kg K 2 O per ha. Top dressing: 120 kg Nitrogen (40 + 40 + 40 ); 60 kg K 2 O (20 + 20 + 20) per ha is applied in three equal splits at 40, 80, 120th day after planting. The plants are earthed up after each application of ferlilisers. Weed control: Reduce competition by weeds. 3-4 weedings are necessary between June to September. After each weeding, mulch is to be replaced. Clumps are removed and earthed up in September. Harvesting: For Green Ginger: 6 months after planting. For Dry Ginger: 8 months after planting, when leaves turn yellow and start drying between 245 to 260 days. Preserved Ginger: 7 months after planting. Before they fully mature, after which they become more fibrous. Light irrigation is given before harvesting. Dig the plants carefully. Soak them overnight. Wash thoroughly. Sundry for a day or two before marketing as green ginger. Yield: Average yield under rain fed condition is 10-15 tonnes per ha. Average yield under irrigated condition is 15 – 25 tonnes per ha.

8 Processing: I. Dry Ginger: Preparation of commercial dry zinger involves a series of steps. Fully developed rhizomes are harvested after 8 months of planting for preparation of Dry Ginger. 1. Soaking in water: The rhizomes are soaked overnight in cement tubs for easy removal of skin. 2.Trampling: The rhizomes are trampled under feet in the tub. Avoid damage to epidermal cells containing flavouring oil. 3. Peeling: The skin is peeled off, with sharp bamboo knives. Don’t rupture epidermal cells. This step hastens drying process. 4.Washing and Drying: The peeled rhizomes are wahsed and sundried for 3-4 days on cement floors. 5.Polishing: After drying the rhizomes are polished by rubbing with a coarse cloth to remove all bits of skin or dirt. These are called unbleached ginger. To get bleached Ginger , peeled rhizomes are soaked in 2% lime water for 6 hours, fumigated with sulphur for 12 hours.
