This study was conducted to examine the yield of lotus leaves and roots per one native white lotus grown in Hoesan, Muan of Jeonnam districts, which were promoted by Muan-Gun, Jeonnam as a local speciality. We planted the rhizomes with 2 internodes in a rubber pot in the middle of April. Then on September, 24, 2008, we dug out the main rhizomes and it had grown by 810cm. From the data, the leaf area was $34,442\;cm^2$, the fresh leaf weight was 1,230g, and the dry leaf weight was 235.4g. The weight of the edible fresh stalk and dry weight leaf were 1,325g and 164.3g. Yield of the white lotus root were 1,480g on Sept. 4, 3,880g on Sept. 20 and 4,172g on Oct. 18. Native white lotus are able to be harvested early as September, however, it is be better that it is harvested in the middle of October based on the yield.

This study was conducted to examine the difference in yield and size of enlarged rhizome according to the kinds of native white lotuses. Four white lotuses (Nelumbo nucifera) were collected from 4 different sites, Jeonbuk Jeonju ('Garam'), Jeonnam Muan ('Hoesan'), Chungnam Buyeo ('Ihnchuisa'), and Chungnam Cheongyang('Cheongyang'). Each enlarged rhizome was planted in an area of 3.3 $m^2$ on 10. April, 2007 and digged out on 19. February, 2008. The yield of enlarged rhizome was in the order of Hoesan (3.0 kg/$m^2$), Cheongyang (2.5 kg/$m^2$), Garam (2.0 kg/$m^2$) and Ihnchuisa (1.0 kg/$m^2$). The number of enlarged rhizomes was in the order of Ihnchuisa (4.9/$m^2$), Garam (4.3/$m^2$), Hoesan (4.2/$m^2$) and Cheongyang (4.1/$m^2$). Total number of nodes in the enlarged rhizomes were much more in the order of Hoesan (17.0/$m^2$), Ihnchuisa (16.0/$m^2$), Cheongyang (15.3/$m^2$) and Garam (14.1/$m^2$). Component ratio of enlarged rhizome length below 50cm for Ihnchuisa, Garam, Hoesan and Cheongyang were 76.3%, 53.0%, 38.2% and 40.3% respectively. Native white lotus had a longer enlarged rhizome in the first node than the other nodes, and their enlarged rhizome length and width became thin. And it became thick and short from the second node of enlarged rhizome. Accordingly the amount of enlarged rhizomes 'Hoesan' was extremely much than others.
