When turmeric is ripening and has to be pulled out of the ground in a fortnight, a trench is dug on an elevated place, preferably a hillock. The trench is dug sufficiently deep enough to accommodate all the turmeric. This trench is left open for 10 to 16 days for sunlight to dry it up. Spread wheat straw and date palm husk at the base of the trench. Thereafter fill this trench with the gunnybags full of turmeric rhizome, till half-a-feet space is left for sealing. Put a lid on the trench and cover it with gunny bags. Again spread wheat straw up to the surface level of the ground and then pack it with mud and plaster it with cowdung. Turmeric can be preserved for three to four months by this technique.

"A pit is dug deep at an elevated site and allowed to dry under Sun for 8-10 days. A sheet layer of date palm leaves is placed at the bottom and along the walls of the pit. Dry wheat husk and straw are filled between the soil and palm leaves. The bags of turmeric are stacked one upon another in the pit till 20 to 25 cm space from the top.”
