The research aims to study the influence of growing media types on seed germination and seedlings growth of papaya IPB 3, IPB 4 and IPB 9 genotypes and know growing medium suitable for growth of papaya seedlings is good and has a light weight to facilitate the transportation of seedlings. The research was conducted in March until September 2011 in the greenhouse FATETA IPB, Leuwikopo Bogor and The Experimental Garden of PKBT IPB, Tajur Bogor. The design used was Randomized Complete Design Group two factors. The first factor is the growing media with 5 kinds with the same ratio (2:1:1), namely M1 = soil: sand: manure, M2 = soil: sand: rice husk charcoal, M3 = soil: sand: cocopeat, M4 = soil: manure: cocopeat, and M5 = soil: manure: rice husk charcoal. The experiment consisted of 15 combinations with 3 replicates then there were 45 experimental units . The results showed that papaya seeds germinate is the highest of the growing media mix of soil, manure, and rice husk charcoal (M5) is 70% and IPB 3 genotype (G1) is 70.91%. The composition of media soil, manure, and rice husk charcoal (M5) with a ratio of 2:1:1 is the best medium for papaya seedlings at 6 MST and has a weight of seedlings per polybag is the lightest compared with other growing media to facilitate the transportation of seedlings.
