Agrotechniques for the cultivation of curcuma zedoaria (berg.) rosc.

Curcumazedoaria (Berg) Rose. (wild turmeric or kastoorimanjal of commerce rhizome is used as appetizer, tonic, blood purifier and cosmetic. It is useful in flatulence and dyspepsia and also for worms and skin diseases a study on the agrotechniques for its cultivation at the aromatic and Medicinal plants Research Station, Odakkali during 1996-1999 revealed that it is highly adaptable to a wide range of spacings, producing similar yields by adjusting the number of plants/hill. It produces maximum yield of rhizome (34t/ha), essential oil (0.33%) and oleoresin (5.%%) when 1.5 t/ha of seed rhizomes are planted at 60 ×40 cm spacing with the receipt of premonsoon showers in May and harvested in January. Application of 20/ha of FYM, 100:50:50 kg N:P:K/ha. Biofertilisers, green manuring and mulching maximize the yields. Combination and interaction effects of the various manorial treatments are to be studied further in detail. The nutrient removal by the crop for the production of rhizomes was115.96:9. 46:111.23 kg NPK/ha.
