PENGARUH MEDIA TUMBUH DAN LAMA PERENDAMAN TERHADAP PERKECAMBAHAN SORGUM VARIETAS NUMBU

Abstract

THE EFFECT OF GROWING MEDIUM AND SOAKING TIME ON GERMINATION OF SORGHUM VAR. NUMBU. The present study was conducted to elaboratethe effect of the growing medium andsoaking times on germination of sorghum varieties numbu. This research has been done to learn and obtain data on the effect of the plant growth media and the soaking times of the sorghum plant sprouts. The experiment consisted of a 3x4x3 factorial design with 3 levels of growing medium (100% original soil; 50% original soil + 50% burned soil; and 100% burned out soil) and 4 levels of soaking times (0,2,4, and 6 hours). After a significant F test (where necesarry) was employed to inspect differences among group means. Statistical difference was accepted at P < 0,05. Variables measured were: germination rates, germination, and leaf counts. Research results showed that growing medium gave a significant difference (P<0,01) on germination phase and germination rates. The interaction of growing medium andsoaking times gave a significant difference on leaf counts.It can be concluded that the growing medium gave a positive response on germination phase andgermination rates; while leaf counts of Sorghum var. Numbu interacted well with growing medium of 100% original soil and all level of soaking times. Keywords: growing medium, soaking times, sorghum var. Numbu, germination.
