The rhizome finds extensive use in the indigenous systems of medicine. The quality of mango- ginger is mainly determined by its volatile oil, non-volatile ether extract (NVEE), fibre and starch contents. They also reported to have antimicrobial, antioxidant, anticancer, anti-inflammatory, antidepressant, antitubercular and platelet aggregation inhibitory activities (Policegoudra et al., 2010). The geographical distribution of the genus ranges from India to Thailand, Indo-China, Malaysia, Indonesia and Northern Australia. It is found wild in parts of West Bengal and is cultivated in Gujarat, Uttar Pradesh, Kerala, International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 08 (2018) Journal homepage: http://www.ijcmas.com Mango ginger (Curcuma amada Roxb.) is popular in Southern and Eastern India mainly due to its typical pleasant flavor. It is a spice cum medicinal plant that has been reported to possess anti-inflammatory, antioxidant and antitumor properties. The rhizomes find an extensive application in the preparation pickles because of its exotic mango aroma. A field experiment was conducted at College of Horticulture, Mudigere to standardize the nutrition levels and seed rhizome weight for getting higher yields. The treatments consisted of two factors viz., rhizome weight (W 1 -20, W 2 -40, W 3 -60g) and nutrition levels (N 1 -Control, N 2 -60:50:100 kg NPK/ha, N 3 -90:75:150 kg NPK/ha, N 4 -120:100:200 kg NPK/ha, N 5 -150:125:250 kg NPK/ha, N 6 -180:150:300 kg NPK/ha). Among 18 treatment combinations, W 3 N 6 (rhizomes weighing 60g with 180:150:300 kg NPK /ha) recorded maximum yield per hectare, essential oil content and it was observed that maximum B:C ratio was recorded in the treatment combination W 1 N 6 (2.11) followed by W 3 N 6 (2.05).
